Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As mentioned above, in practical applications, a server is often connected to a plurality of remote terminals of different models or types, the screen sizes and resolutions of the remote terminals are usually different, and when the APPs are respectively tested on the remote terminals, the server usually adjusts different display scales in order to fully display the screen of the remote terminal on the software of the user PC.
For example, due to the difference between the screen sizes and resolutions of the remote terminal 1 and the remote terminal 2, the resolution of the picture showing the screen of the remote terminal 1 is 3000 × 4000, the resolution of the picture showing the screen of the remote terminal 2 is 3500 × 5000, and the resolution on the user PC is 1024 × 1024; in order to fully present the screen of the remote terminal 1 and the screen of the remote terminal 2, different display scales are generally adjusted. Wherein the adjusted horizontal ratio is about 1/3 and the vertical ratio is about 1/4 when the screen of the remote terminal 1 is displayed, and the adjusted horizontal ratio is about 1/3.5 and the vertical ratio is about 1/5 when the screen of the remote terminal 2 is displayed.
Based on this, the embodiment of the present application provides a terminal display method, which can be used for the problems in the prior art. In order to facilitate understanding of the terminal display method provided by the application, a simple introduction can be firstly made to the remote real machine test system. As shown in fig. 1, the system 10 is a schematic structural diagram of the system 10, and the system 10 includes a user side 11 and a server side 12, where the server side 12 includes a server 121, a controller 122, and a plurality of terminals (including a terminal 1, a terminal 2, and a terminal n) connected to the controller 122.
In the system 10, the user terminal 10 may be a PC (personal computer), a mobile phone, a tablet, etc. used by the user for testing, and the screen of the terminal may be displayed on the software of the user terminal 10. Where the software may typically be a web browser or other application, etc.
The plurality of terminals included in the server 12 may be mobile phones, computers, tablets, or the like, and the terminals are installed with Agent agents, and data of a screen can be obtained from a terminal memory through the Agent agents, and the data can be used to generate a picture, and the picture can show the screen of the terminal.
For example, the terminal 1 is installed with an Agent, and the Agent can obtain data of the screen of the terminal 1 from the memory of the terminal 1, so as to generate a picture according to the data, so as to display the screen of the terminal 1.
And a controller 122 in the server 12, wherein the controller 122 is connected to the server 121 at one end, is connected to a plurality of terminals at the other end, and can be used for receiving pictures generated and sent by each terminal through the Agent program Agent. In practical applications, the server 12 may include a plurality of controllers 122, and the controllers 122 are respectively connected to the server 121 and a plurality of terminals.
The server 121 is connected to the user terminal 11 and the controller 122, and can obtain the picture from the controller 122 and send the obtained picture to the user terminal 11. In addition, the server 121 may also install the APP to be tested on the terminal of the model or type selected by the user according to the selection of the user, where the terminal on which the APP to be tested is installed is the terminal to be displayed; of course, if the user does not select to test on a certain terminal, the server 121 may also randomly select to install the APP to be tested on the certain terminal, or determine the certain terminal according to a preset priority order or other rules, and install the APP to be tested on the certain terminal.
For example, the terminals 1 to n are mobile phones of different models, and the user needs to test the APP on the terminal 2; at this time, the user can upload the APP to the server 121 through the user terminal 11, and select the terminal 2 as a test terminal, and after the server 121 receives the APP, the APP is installed in the terminal 2 according to the selection of the user, so as to perform a test.
The above is a brief introduction to the system 10, and the terminal display method provided by the embodiment of the present application can be specifically described below with reference to fig. 1 and fig. 2. As shown in fig. 2, the method comprises the following specific steps:
step S21: and determining a picture for displaying a terminal screen.
The picture is generated by acquiring data in a memory of the terminal according to an Agent program Agent on the terminal to be displayed (which may be any one of the terminal 1 to the terminal n), wherein the data can reflect the brightness and color specifically displayed by each pixel on the screen of the terminal, and therefore, the picture for displaying the screen of the terminal can be generated through the data.
In addition, the picture determined to be used for displaying the terminal screen may be an Agent on the terminal to be displayed in the server 12, the Agent acquires data from a memory of the terminal to be displayed and generates a picture according to the data, and after the Agent generates the picture, the Agent may send the picture to the controller 122, so that the server 121 can acquire the picture from the controller 122. In this way, the Agent on the terminal to be displayed generates a picture, and transfers the picture to the server 12 to connect with the controller 122 of the terminal to be displayed. Of course, the picture for displaying the terminal screen is determined, and the server 121 in the server 12 may also obtain the picture from the terminal to be displayed through the controller 122.
Step S22: compressing the picture, wherein the horizontal resolution of the compressed picture is less than or equal to a horizontal threshold and the vertical resolution is less than or equal to a vertical threshold.
The image compression method may generally be in various manners, for example, the image may be compressed by using image processing software such as ACDS, Photoshop, and the like, and may also be compressed by using other manners, where the specific manner used for compressing the image is not limited, and only the horizontal resolution of the compressed image is less than or equal to the horizontal threshold, and the vertical resolution is less than or equal to the vertical threshold.
It should be noted that, the sizes of the horizontal threshold and the vertical threshold may be preset and modified, in the specific setting and modifying process, the network transmission speed of the user may be detected first, and then the sizes of the horizontal threshold and the vertical threshold are determined according to the network transmission speed of the user, for example, when the network transmission speed is fast, a relatively large horizontal threshold and a relatively large vertical threshold may be set, so that the compressed picture is relatively large, the display effect on the terminal screen is good, and when the network transmission speed is slow, a relatively small horizontal threshold and a relatively small vertical threshold may be set, so that the compressed picture is relatively small and is easier to transmit.
The horizontal threshold and the vertical threshold may be set to fixed values as needed, for example, the horizontal threshold may be set to 750, and the vertical threshold may be set to 1024 (of course, other values may be used). Generally, the horizontal threshold and the vertical threshold are both set to be fixed values, which is more convenient for displaying in a fixed area of the user terminal, for example, the user terminal may display a compressed picture through a web browser, the picture is usually displayed in a fixed area allocated in a web of the web browser, and the horizontal threshold and the vertical threshold are both set to be fixed values, which is more convenient for dividing the fixed area, so as to display the picture. Of course, the fixed values of the horizontal threshold and the vertical threshold may be determined according to a/B test or the like.
In order to make the horizontal resolution of the compressed picture equal to or less than the horizontal threshold and the vertical resolution equal to or less than the vertical threshold, the compression may be performed while keeping the aspect ratio or may be performed without keeping the aspect ratio.
When the aspect ratio is kept compressed and the compressed lines are compressed, there are various ways, such as determining a horizontal compression ratio according to the horizontal resolution of the picture, wherein the horizontal compression ratio is used for indicating that the horizontal resolution of the picture is compressed to be less than or equal to a horizontal threshold, and after determining the horizontal compression ratio, compressing the picture according to the horizontal compression ratio under the condition of keeping the aspect ratio; or determining a vertical compression rate according to the vertical resolution of the picture before compression, wherein the vertical compression rate is used for indicating that the vertical resolution of the picture is compressed to be less than or equal to a vertical threshold, and after determining the vertical compression rate, compressing the picture according to the vertical compression rate under the condition of keeping the aspect ratio. When aspect ratio compression is usually maintained, the compressed picture is not easily distorted.
Of course, the compression may be performed without maintaining the aspect ratio, and at this time, a horizontal compression rate may be determined according to the horizontal resolution of the picture, and a vertical compression rate may be determined according to the vertical resolution of the picture, where the horizontal compression rate is used to instruct to compress the horizontal resolution of the picture to equal to or less than a horizontal threshold, the vertical compression rate is used to instruct to compress the vertical resolution of the picture to equal to or less than a horizontal threshold, and after the horizontal compression rate and the vertical compression rate are determined, the picture is compressed according to the horizontal compression rate and the vertical compression rate. Compression without maintaining aspect ratio is generally more flexible since the horizontal compression ratio and the vertical compression ratio can be set independently.
The compressing of the picture may be performed by the server 121 in the server 12, or may be performed by the controller 122. For example, when it is determined that the picture for displaying the terminal screen is specifically, the server 121 in the server 12 obtains the picture from the terminal to be displayed through the controller 122 (the picture is generated by the terminal to be displayed through the Agent), the server 121 performs the step of compressing the picture in step S22; when it is determined that the picture for displaying the terminal screen is specifically, when the controller 122 in the server 12 receives the picture from the terminal to be displayed, the step of compressing the picture by the controller 122 may be performed, or the step of compressing the picture by the server 121 may also be performed, and if the server 121 compresses the picture at this time, the server 121 should further obtain the picture from the controller 122.
Step S23: and sending the compressed picture to a user terminal 11 for displaying the compressed picture with the horizontal resolution of the horizontal threshold and the vertical resolution of the vertical threshold through the user terminal 11.
The compressed picture can be sent to the user terminal 11 through the server 121 in the server 12, and when the server 121 sends the compressed picture, a plurality of different sending modes can be adopted, for example, the compressed picture can be sent to the user terminal 11 in a video streaming (streaming media) mode, so that the user terminal can display the compressed picture through an application program such as a video streaming player or a web browser; of course, the compressed picture may also be sent to the user end 11 in a fixed frame rate (sending a fixed number of pictures per second); of course, in practical applications, the server 121 may also send the compressed picture to the user end 11 in other manners, which is not described herein again.
Of course, after receiving the compressed picture sent by the server 121, the user terminal 11 may display the corresponding terminal screen by displaying the picture. The way of the user end 11 displaying the compressed picture may be various, for example, the compressed picture may be displayed through a web browser, and in order to display the compressed picture at a fixed position of the web browser, the horizontal threshold may be used as a horizontal resolution, and the vertical threshold may be used as a vertical resolution to display the compressed picture.
Fig. 3 is a schematic diagram of the user terminal 11 displaying the compressed picture through a web browser. In fig. 3, the user terminal 11 is specifically a PC, the terminal is a mobile phone, and the user performs APP test on a remote mobile phone through the PC and displays a screen of the mobile phone through a web browser on the PC. As can be seen from fig. 3, the left side is a mobile phone screen displayed on a web browser, multiple APPs such as "music", "mail", and the like are displayed on the mobile phone screen, a terminal identifier (including a model of the mobile phone, and the like) is provided above the mobile phone screen, and the left side of the terminal identifier can adjust displayed definition (including modes such as high definition, smoothness, and the like) and a button for displaying a horizontal screen or a vertical screen of the mobile phone screen; the right side of the web browser comprises a space, for example, the user can click an 'upload local application' under the 'application' to upload an APP to be tested, and the lower part comprises a plurality of information display labels.
By adopting the terminal display method provided by the embodiment of the application, after the picture for displaying the terminal screen is determined, the picture is compressed, so that the horizontal resolution of the compressed picture is less than or equal to the horizontal threshold and the vertical resolution is less than or equal to the vertical threshold, and then the compressed picture is sent to the user side for displaying the compressed picture through the user side according to the horizontal resolution of the horizontal threshold and the vertical resolution of the vertical threshold. Therefore, when the screens of different terminals are displayed on the software of the client PC, even if the screen sizes or resolutions are different, the pictures for displaying the terminal screens can be completely displayed by adopting the same display proportion because the horizontal resolution of the pictures is compressed to be less than or equal to the horizontal threshold and the vertical resolution is compressed to be less than or equal to the vertical threshold, thereby improving the display effect. In addition, after the picture is compressed, the size of the picture file can be reduced, and occupied network transmission resources can be reduced when the picture file is sent to the user side.
It should be noted that all execution main bodies of the steps of the terminal display method provided in the embodiment of the present application may be the same device, or all the steps of the method may also be executed by different devices. For example, the execution subjects of step S21 and step S22 may be the apparatus 1; for another example, the execution subject of step S21 may be device 1, and the execution subjects of steps S22 and S2; and so on.
The foregoing is a specific description of the terminal display method provided in the embodiments of the present application, and for convenience of understanding, the method may be further described with reference to specific examples. In this example, the user side is specifically a PC, the software for displaying the terminal screen on the user side PC is specifically a web browser, the terminal of the server side is specifically a mobile phone (including mobile phones 1 to n), and the mobile phone is installed with an Agent. The user uploads the APP to be tested to the server through the web browser, selects a mobile phone (which may be any one of the mobile phones 1 to n, and is referred to as a target mobile phone) specifically used for testing, and then the server installs the APP to be tested into the target mobile phone according to the selection of the user. The whole testing process is shown in fig. 4, and comprises the following steps:
step S31: a user uploads an APP to be tested through a PC (personal computer), and selects a target mobile phone as a mobile phone for testing;
step S32: the server receives the APP to be tested and installs the APP to be tested on the target mobile phone according to the selection of the user;
step S33: an Agent on the target mobile phone acquires data in the memory, generates a picture and sends the picture to the controller;
the data acquired by the Agent program Agent from the memory can reflect the specific displayed brightness and color of each pixel on the screen of the target mobile phone.
Step S34: the controller compresses the received picture, wherein the horizontal resolution of the compressed picture is less than or equal to a horizontal threshold and the vertical resolution is less than or equal to a vertical threshold;
step S35: the server acquires a compressed picture from the controller;
step S36: the server sends the compressed picture to a PC of a user;
step S37: and the user PC displays the compressed picture through a web browser at the horizontal resolution of the horizontal threshold and the vertical resolution of the vertical threshold.
