If the incoming request is /release/apia/20171012/index.html
and the API with the path of /apia/
is hit, then:
/apia/20171012/index.html
;/endpoint/
, /apia/
will be cut off and the remainder will be pasted after the backend path to form /endpoint/20171012/index.html
.=
, it will have the highest priority, and exact match will be used.^~
, it will have the second priority and cannot contain regular expressions, and prefix match will be used.When creating an API, if you select "Support CORS", then API Gateway will support cross-origin requests. The default configuration is as follows:
#define CORS_DEFAULT_AC_ALLOW_ORIGIN ("*")
#define CORS_DEFAULT_AC_ALLOW_METHODS ("GET,POST,PUT,DELETE,HEAD,OPTIONS,PATCH")
#define CORS_DEFAULT_AC_ALLOW_CREDENTIALS ("true")
#define CORS_DEFAULT_AC_ALLOW_HEADERS ("X-Api-ID,X-Service-RateLimit,X-UsagePlan-RateLimit,X-UsagePlan-Quota,Cache- Control,Connection,Content-Disposition,Date,Keep-Alive,Pragma,Via,Accept,Accept-Charset,Accept-Encoding,Accept-Language,Authorization,Cookie,Expect,From,Host,If-Match,If-Modified-Since,If-None-Match,If-Range,If-Unmodified-Since,Range,Origin,Referer,User-Agent,X-Forwarded-For,X-Forwarded-Host,X-Forwarded-Proto,Accept-Range,Age,Content-Range,Content-Security-Policy,ETag,Expires,Last-Modified,Location,Server,Set-Cookie,Trailer,Transfer-Encoding,Vary,Allow,Content-Encoding,Content-Language,Content-Length,Content-Location,Content-Type")
#define CORS_DEFAULT_AC_EXPOSE_HEADERS (CORS_DEFAULT_AC_ALLOW_HEADERS)
#define CORS_DEFAULT_AC_MAX_AGE ("86400")
After you create an API service, if calls to it often fail with the following prompt returned:{"message":"There is no api match uri[\/api\/v1\/tool\/123\/ico] host [service-asoj98o0-1251762227.ap-guangzhou.apigateway.myqcloud.com]"}
Check whether the API service has been published in an environment.
A created API service can be called only after it is published in an environment. If it is modified, it won't take effect until it is published again.
If a service is published in different environments, the default call address should contain the environment name, such as:service-asoj98o0-1251762227.ap-guangzhou.apigateway.myqcloud.com/release/user path
