Endpoint resolution

1. User-defined

   The user-defined method has the highest priority. It lets you specify the exact endpoint.

   # Takes effect globally
   client = AcsClient()
   client.add_endpoint("<region_id>", "<product>", "<endpoint>")
   
   # Takes effect only for the current request
   request = DescribeRegionsRequest()
   request.set_endpoint("<endpoint>")

2. Endpoint construction rule

   This resolution method applies only when you send a request over a VPC network or when the product SDK has an endpoint data file. For an example of an endpoint data file, see the Ecs Endpoint Data File.

   # Public network request
   request.request_network = "public" # Because the default value of `network` is `public`, you do not need to configure `network` by default.
   
   # Cross-origin request
   request.request_network = "share"
   
   # IPv6 request
   request.request_network = "ipv6"
   
   # Proxy request
   request.request_network = "proxy"
   
   # Internal request
   request.request_network = "inner"
   
   # IPv4/IPv6 dual-stack
   request.request_network = "dualstack"
   
   # VPC request
   request.request_network = "vpc"

3. Resolution based on the endpoints.json data file in the Python SDK Core

   This is an internal operation and requires no extra configuration.

4. Remote retrieval using the Location Service API

   The product SDK must have a ServiceCode.
