Journey, operate in same physical machine.
Specifically, Fig. 2 is based on, as shown in figure 3, the embodiment of the present invention provides a kind of determination method of cache policy, the party
Method can include：
S101, API manage cluster and carry out statistical to the multiple API request message received and multiple API response messages
Analysis.
The plurality of API request message corresponds with the plurality of API response messages, and each API request message is corresponding
API response messages in carry identical AP mark.
In embodiments of the present invention, API manages cluster and can respond the API request message received and corresponding API
Message is input in caching analysis module, is counted according to API marks, to determine that the API for carrying each API marks is responded
Whether message can be cached, and obtain statistic analysis result in the case of it is determined that can cache.
In one example, API, which manages cluster, can analyse whether a period be present, and API is managed within the period
Content all phases of API response messages corresponding to the API request message for the identical API marks of all carryings that reason cluster receives
Together, whether the content of the API response messages of API marks is carried with determination can be cached.
By taking the first API marks as an example, API manages cluster and responded by the API request message to receiving and corresponding API
After message carries out statistical analysis, if in first time period, corresponding to the API request message of the first API of all carryings marks
The content all same of API response messages, then carrying the content of the API response messages of the first API marks can be cached, API
Management cluster can count the content identical first time period for the API response messages for carrying the first API marks, to be united
Count analysis result.
Wherein, first time period is that API manages receive first of cluster and carries the first API in the first time period
At the time of the API request message of mark, to the first time period in API management cluster receive last carry this first
Corresponding to the API request message of API marks at the time of API response messages.
For example, it is assumed that the xxxx xx months 01, API management clusters have received 10000 and carry the first API marks
API response messages corresponding to API request message and each API request message.If API manages cluster by statistical analysis, really
API request message pair of the fixed 100th API request message for carrying the first API marks to the 1000th carrying the first API mark
The content for the API response messages answered all is identical, and API management clusters can then determine to carry the API request of the first API marks
The content of API response messages can be cached corresponding to message.
So, API manage cluster can according to receive the 100th carry the first API identify API request message when
At the time of carving, and receive API response messages corresponding to the 1000th API request message for carrying the first API marks, the is determined
One period.For example, API manages cluster the 01 day 9 xxxx xx months:When 00, receive the 100th and carry the first API marks
The API request message of knowledge, the 01 day 10 xxxx xx months:When 00, receiving the 1000th API for carrying the first API marks please
API response messages corresponding to message are sought, i.e. first time period is on the xxxx xx months 01 9:00~10:00.So as to API management
The statistic analysis result that cluster obtains is the 01 day 9 xxxx xx months:00~10:The API of 00, the first API of all carryings mark
The content all same of API response messages corresponding to request message.
It should be noted that in the examples described above, API manages cluster in first time period, the carrying first received
The parameter carried in all API request message of API marks may be identical, it is also possible to entirely different, it is also possible to possess phase
Same partial parameters, but other specification is different.
In one example, API, which manages cluster, can analyse whether a period be present, and API is managed within the period
The API responses corresponding to the identical API marks of all carryings and the API request message of same section parameter that reason cluster receives disappear
The content of breath is all identical, to determine whether the content for carrying API marks and the API response messages of the partial parameters can be carried out
Caching.Wherein, API request message API response messages corresponding with its carry identical API marks and partial parameters.
By taking the first API marks and the first parameter as an example, if API manages cluster in first time period, what is received is all
The content all same of API response messages corresponding to the API request message of the first API marks and the first parameter is carried, then carries the
One API is identified and the content of the API response messages of the first parameter can be cached, and API management clusters can count carrying
First API is identified and the content identical first time period of the API response messages of the first parameter, to obtain statistic analysis result.
In embodiments of the present invention, first time period is that API manages first that cluster receives in the first time period
Carry the first API mark and the first parameter API request message at the time of, to the first time period in API management cluster connect
At the time of receiving API response messages corresponding to the API request message that last carries the first API marks and the first parameter.
Wherein, the first parameter in API request message can be the URL of the API request message
Parameter (parameters) in (Uniform Resoure Locator, URL), accordingly, first in API response messages
Parameter is the parameter in the URL of the API response messages；The first parameter in API request message can also be the API request message
Data volume (body) in parameter, accordingly, the first parameter in the API response messages can also be the API response messages
Data volume in parameter.
In one example, when multiple periods in a cycle being present, each period in the plurality of period
In, the content of API response messages corresponding to the request message for the API of all carryings the first marks that API management clusters receive is all
When identical, the plurality of period can be respectively a first time period, can also form a first time period.
For example, the 9 of the xxxx xx months 01:00~10:00,11:00~12:00, and 15:00~16:00 this three
In each period in the individual period, the request message for the API of all carryings the first marks that API management clusters receive is corresponding
API response messages content it is all identical, or, API management cluster receive the API of all carryings the first mark and first ginseng
The content of API response messages is all identical corresponding to several request messages, then can be by 9:00~10:00,11:00~12:00, with
And 15:00~16:The period set of 00 these three periods composition is defined as first time period.Can also be by 9:00~
10:00,11:00~12:00, and 15:00~16:00 is identified as a first time period.
In one example, API manage cluster to the API of carrying the first that the receives multiple API request message identified and
Before API response messages corresponding to each API request message carry out statistical analysis, API management cluster can also be to receiving
The QoS class informations carried in API request message are verified, it is determined that the QoS class informations received whether meet it is default etc.
Level.
For example, the class information carried in API request message can include App QoS grades, or the QoS of App user
Grade, accordingly, predetermined level can be gold medal App grades, or Gold Subscriber grade etc..
For example, the QoS grades of the App user carried in the API request message that API management clusters receive are Gold Subscriber
Grade, then the API request message and its corresponding API response messages can be input in caching analysis module and carry out statistical
Analysis.
I.e. in embodiments of the present invention, if the grade letter carried in multiple API request message that API management clusters receive
Breath meets predetermined level, and API management clusters then carry out statistical analysis to the plurality of API request message and multiple API response messages.
So as to realize that high-grade App or user API request preferentially carry out caching analysis.
S102, API management cluster determine cache-time section according to statistic analysis result.
Wherein, it is corresponding with the first time period in the cycle after cache-time section cycle where first time period
Period.
For example, it is assumed that 1 day is 1 cycle, first time period is on the xxxx xx months 01 9:00~10:00, then
9 in every day after the xxxx xx months 01:00~10:00 is the period corresponding with first time period.At this
In inventive embodiments, API manages 9 in every day after cluster can determine the xxxx xx months 01 according to the actual requirements:
00~10:00 is cache-time section, can also determine 9 in every day in one month after the xxxx xx months 01:00
~10:00 is cache-time section, on the other hand, the embodiment of the present invention is not restricted.
In one example, when multiple periods in a cycle being present, each period in the plurality of period
In, the content of API response messages corresponding to the request message for the API of all carryings the first marks that API management clusters receive is all
When identical, if multiple periods can be respectively a first time period, API management clusters can then be directed to each period
Determine a cache policy；If a time collection of the plurality of period composition is combined into first time period, first time period can be with
A period being made up of multiple periods gathers, and API management clusters can then determine that one is delayed according to the plurality of period
Deposit strategy.
S103, API management cluster determine cache policy, and the cache policy is used to indicate API management clusters according to caching
First received in period carries the content of API response messages corresponding to the API request message of the first API marks, right
