Alibaba Cloud SDK:Configure a proxy

Configuration method

• The following code provides an example on how to configure a proxy when you initialize an SDK client.

  import (
  	"fmt"
  
  	"os"
  
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk/auth/credentials"
  	ecs "github.com/aliyun/alibaba-cloud-sdk-go/services/ecs"
  )
  
  func main() {
  	// Specify runtime parameters.
  	config := sdk.NewConfig()
  	// Use the AccessKey ID and AccessKey secret of the Resource Access Management (RAM) user.
  	credential := credentials.NewAccessKeyCredential(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"), os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
  	client, err := ecs.NewClientWithOptions("cn-hangzhou", config, credential)
  	if err != nil {
  		panic(err)
  	}
  	// Configure a proxy when you initialize an SDK client.
  	client.SetHttpsProxy("http://user:password@127.0.0.1:8989") // Configure an HTTPS proxy.
  	client.SetHttpProxy("http://127.0.0.1:8080")                // Configure an HTTP proxy.
  	client.SetNoProxy("127.0.0.1,localhost")                    // Configure the IP addresses or domain names that do not require proxies.
  
  	// Create a request.
  	request := ecs.CreateDescribeRegionsRequest()
  	request.Scheme = "https"
  	// The request parameters.
  	request.InstanceChargeType = "PrePaid" // The billing method of the instance.
  	request.ResourceType = "instance"      // The resource type.
  	// Send the request and obtain a response.
  	response, err := client.DescribeRegions(request)
  	if err != nil {
  		fmt.Print(err.Error())
  	}
  	fmt.Printf("response is %#v\n", response)
  }

• You can also use the following environment variables to configure a proxy:

  • HTTP_PROXY or http_proxy. Example of a valid value: http://127.0.0.1:8080.

  • HTTPS_PROXY or https_proxy. Set the environment variable in the following format: http://<user>:<password>@127.0.0.1:8989.

  • NO_PROXY or no_proxy. Set the environment variable in the following format: 127.0.0.1,localhost.
