Example 2
The Web service gray scale release control method provided by this embodiment is further refined on the basis of embodiment 1, and is mainly embodied in that:
the grayscale strategy of the present embodiment includes grayscale control logic and verification logic. The gray scale strategy can be specifically configured with a plurality of configuration items, and is favorable for realizing more complex gray scale control and version verification. The configuration items for implementing the gray scale control logic may include, but are not limited to, configurations:
KEY (KEY, e.g., KEY = request URL) for matching of the grayscale policy;
URL (old _ version _ URL) of the original version;
the Web service specifies at least one alternate version of access (version, such as version = version N, N being a positive integer);
URL of each alternative version (version N _ URL, which may be a relative path such as/tem/v 1, or an absolute path such as server internal forwarding address http:// a.local/item/v1, redirection address http:// a.com/item/v 1);
control logic for each alternate version (version _ control _ logic, e.g., version _ control _ logic = lua code);
a request distribution policy (version n _ dispatch, e.g., version n _ dispatch = redirect/forward) for each alternate version, the request distribution policy being used to indicate whether a server internally forwards to the url of the version n or redirects to the url of the version n when distributing a request;
whether each alternative version is executed in the background (such as version n _ background = 0/1), if so, it means that the traffic is copied to version n without executing the gray logic;
exception handling rules for each alternate version, the exception handling rules for configuring at least one exception logic and corresponding solutions when the exception logic occurs, wherein the exception logic preferably includes, but is not limited to, at least one of the following conditions:
generating an erroneous response status code (versionjerror _ status, such as versionjerror _ status =404,500,502, 503);
an access timeout (version n _ timeout, e.g., version n _ timeout =5 s);
access limit (version _ limit, e.g., version _ limit = 100/s);
the solutions corresponding to the above conditions may be the same or different, and the solutions of the present embodiment preferably include but are not limited to: forwarding the access request to the original version.
The verification logic is configured to verify whether the contents of the alternate version are correct. Configuration items for implementing the verification logic may include, but are not limited to, configuration:
a verification rule (version n _ validity _ rule, for example, version n _ validity _ rule = lua code) is used to verify whether the content of version n is correct, and if 0 is returned, it indicates that the verification fails.
The configuration items of each alternative version may be the same or different according to actual needs. The specific configuration of each configuration item can be the same or different according to actual needs.
Fig. 2 shows a Web service gradation issuance control method of the present embodiment. For the gray scale control logic of the present embodiment, the method for controlling Web service gray scale issuance includes the following steps:
step 21: receiving an access request of a client, wherein the access request comprises a request URL, a source IP, a request parameter and a request header, and the request URL is used for representing a Web service which is requested to be accessed.
Step 22: and using the request URL to acquire a KEY as a gray level strategy of the request URL.
Step 23: and judging whether the alternative version of the gray scale control logic configuration of the gray scale strategy is empty, if so, executing the step 24, and if not, executing the step 25.
Step 24: forwarding the access request to the original version of the URL.
Step 25: executing the control logic of the alternative versions one by one until finding the alternative version hit by the value of the client on the preset information, taking the hit alternative version as the corresponding alternative version, and then executing step 27. For example, assuming that the candidate versions of the Web service designated access are version1 and version2, the control logic of version1 is executed first, where dynamic configuration can be realized by loadstring (one function type) dynamic parsing script using lua (one scripting language) scripting language, the request URL, the source IP, the request parameter and the request header are transmitted to the lua function and executed, assuming that the access request is forwarded to version1 with the preset information uid and the preset uid mantissas 1, 3 and 5, if the executed return value is 1, it indicates that version1 is hit, otherwise it indicates that version1 is not hit, then the control logic of version2 is executed, and it is also determined whether the return value is 1, if return 1, it indicates that version2 is hit, otherwise, it indicates that version2 is not hit.
Step 26: if the value of the client on the preset information does not hit any alternative version, step 24 is executed.
Step 27: forwarding the access request to the corresponding alternate version of the URL. When the access request is forwarded to the corresponding alternative version, request distribution is required to be carried out according to the request distribution strategy, if the access request is forwarded, the request distribution strategy indicates that the access request is internally forwarded to the URL of the corresponding alternative version, and if the access request is redirected, the request distribution strategy indicates that the access request is redirected to the URL of the corresponding alternative version; and if the corresponding alternative version is configured to be executed in the background, the background forwards the access request to the corresponding alternative version, and judges whether the corresponding alternative version is correct or not by observing a log under the condition of not being online.
Step 28: and judging whether any abnormal logic appears or not, wherein the judgment includes whether a response state code is correct after a response is forwarded and returned, whether the response state code is overtime or not and whether the current is limited or not, if any abnormal logic appears, executing the step 24, and if any abnormal logic does not appear, executing the step 29.
Step 29: and verifying whether the response result of the alternative version is correct according to the verification logic, and if the response result of the alternative version is incorrect, executing the step 24.
In this embodiment, the control of the gray release is very flexible, can support multi-version gray, can support the configuration of gray, can support complex gray control and verification logic, can copy the flow to come the gray verification function, can flexibly and adaptively handle abnormal logic, and can be quickly and automatically degraded to the original version for processing when encountering problems without worrying about influencing user experience, thereby realizing flexible multi-version gray.
The Web-gray-scale service publishing control method in embodiment 1 and embodiment 2 can be implemented by using a Nginx (a high-performance HTTP and reverse proxy service, and also an IMAP/POP3/SMTP service) access layer (or by using other technologies similar to the Nginx, such as writing an access layer in go language) + lua.

The obtaining module 52 is configured to obtain the KEY as the grayscale policy of the request URL by using the request URL.
The determining module 53 is configured to determine whether the candidate version configured by the grayscale control logic is empty, if so, invoke the forwarding module 54 to forward the access request to the URL of the original version, if not, execute the control logic of each candidate version one by one until finding the candidate version hit by the value of the client on the preset information, then regard the hit candidate version as the corresponding candidate version, invoke the forwarding module 54 to forward the access request to the URL of the corresponding candidate version, and if not, invoke the forwarding module 54 to forward the access request to the URL of the original version.
When the forwarding module 54 forwards the access request to the URL of the corresponding alternative version, it needs to perform request distribution according to the request distribution policy, if the access request is forwarded, it indicates that the access request is forwarded to the URL of the corresponding alternative version inside the server, and if the access request is redirected, it indicates that the access request is redirected to the URL of the corresponding alternative version; and if the corresponding alternative version is configured to be executed in the background, the background forwards the access request to the corresponding alternative version, and judges whether the corresponding alternative version is correct or not by observing a log under the condition of not being online.
The exception handling module 55 is configured to, after forwarding the access request to the URL of the corresponding candidate version, determine whether any exception logic occurs, including whether a response status code is correct after forwarding a return response, whether timeout occurs, and whether current limiting occurs, and if any exception logic occurs, invoke the forwarding module 54 to forward the access request to the URL of the original version.
The verification module 56 is configured to, after forwarding the access request to the URL of the corresponding alternative version, verify whether the response result of the alternative version is correct according to the verification logic, and if the verification is incorrect, invoke the forwarding module 54 to forward the access request to the URL of the original version.

Example 6
Fig. 6 shows a gradation control system of the present embodiment. The gradation control system 60 includes: the module 61 is configured. The configuration module 61 is configured to configure a grayscale policy.
In this embodiment, the grayscale strategy includes grayscale control logic. The gray control logic is used for configuring at least one alternative version which is distinguished by the Web service according to the preset information and is appointed to access. The gray control logic of this embodiment indicates that the client has different values in the preset information, and the alternative versions of the Web service designated for access are different.
In this embodiment, the preset information includes at least one of an IP, a uid, a User-Agent, and a third-party service caller, and compared with the conventional gray-scale distribution, the preset information is more information capable of supporting gray-scale, so that the entire gray-scale distribution is more flexible.
The gray scale strategy can be specifically configured with a plurality of configuration items, which is beneficial to realizing more complex gray scale control. The configuration items for implementing the gray scale control logic may include, but are not limited to, configuration items:
KEY (KEY, e.g., KEY = request URL) for matching of grayscale policy;
URL of the original version (old _ version _ URL);
the Web service specifies at least one alternative version of access (version, such as version = version N, N is a positive integer);
URL of each alternative version (version N _ URL, which may be a relative path such as/tem/v 1, or an absolute path such as server internal forwarding address http:// a.local/item/v1, redirection address http:// a.com/item/v 1);
control logic for each alternate version (version n _ control _ logic, e.g., version n _ control _ logic = lua code);
a request distribution policy (versionjdispatch, such as versionjdispatch = redirect/forward) for each alternate version, the request distribution policy being used to indicate whether a server internally forwards to the url of versionN or redirects to the url of versionN when distributing a request;
whether each alternative version is executed in the background (such as version n _ background = 0/1), if so, it means that the traffic is copied to version n without executing the gray logic;
exception handling rules for each alternate version, the exception handling rules for configuring at least one exception logic and corresponding solutions when the exception logic occurs, wherein the exception logic preferably includes, but is not limited to, at least one of the following conditions:
generating an error response status code (version n _ error _ status, e.g., version n _ error _ status =404,500,502, 503);
an access timeout (version n _ timeout, e.g., version n _ timeout =5 s);
access limit (version _ limit, e.g., version _ limit = 100/s);
the solutions for the above conditions may be the same or different, and the solutions of the present embodiment preferably include but are not limited to: forwarding the access request to the original version.
In this embodiment, the grayscale policy may further include a verification logic. The verification logic is to verify whether the contents of the alternate version are correct. Configuration items for implementing the verification logic may include, but are not limited to, configuration:
a verification rule (version n _ validity _ rule, for example, version n _ validity _ rule = lua code) is used to verify whether the content of version n is correct, and if 0 is returned, it indicates that the verification fails.
The configuration items of each alternative version may be the same or different according to actual needs. The specific configuration of each configuration item can be the same or different according to actual needs.
The gray scale control system 60 of the present embodiment may be used alone to implement the configuration of the complex gray scale policy, or may be used in conjunction with the Web service gray scale distribution control apparatus 40 or 50 in embodiment 4 or embodiment 5, for example:
a Web service system as shown in fig. 7 includes a Web service gradation issuance control apparatus 40 or 50 and a gradation control system 60. The Web service gray scale release control device 40 or 50 calls the gray scale control system 60 after receiving the access request of the client, and the gray scale control system 60 returns the gray scale strategy matched with the Web service to the Web service gray scale release control device 40 or 50 to ensure the gray scale control. The Web service system may further include a Web server 70 that publishes the original version and a Web server 80 that publishes the alternative version.
