V2.0 Go SDK如何配置網路代理程式 - Alibaba Cloud SDK

本文為您介紹V2.0 Go SDK對於代理的配置方式。

V2.0 SDK代理配置方式

說明

代理配置優先順序：RuntimeOption配置->Client配置，優先順序依次降低。

通過運行時參數（RuntimeOptions）配置當前請求的代理。

package main

import (
	"encoding/json"
	"fmt"
	"os"

	openapi "github.com/alibabacloud-go/darabonba-openapi/v2/client"
	ecs20140526 "github.com/alibabacloud-go/ecs-20140526/v4/client"
	util "github.com/alibabacloud-go/tea-utils/v2/service"
	"github.com/alibabacloud-go/tea/tea"
)

func main() {
	config := &openapi.Config{
		// 從環境變數擷取RAM使用者的AccessKey ID
		AccessKeyId: tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID")),
		// 從環境變數擷取RAM使用者的AccessKey Secret
		AccessKeySecret: tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET")),
		// Region ID
		RegionId: tea.String("<RegionId>"),
	}
	client, _err := ecs20140526.NewClient(config)
	if _err != nil {
		panic(_err)
	}
	describeRegionsRequest := &ecs20140526.DescribeRegionsRequest{}
	// 建立RuntimeObject執行個體並設定運行參數。
	runtime := &util.RuntimeOptions{}
	// 通過RuntimeOptions配置代理
	runtime.HttpProxy = tea.String("http://127.0.0.1:9898")
	runtime.HttpsProxy = tea.String("http://user:password@127.0.0.1:8989")
	runtime.NoProxy = tea.String("127.0.0.1,localhost")
	resp, _err := client.DescribeRegionsWithOptions(describeRegionsRequest, runtime)
	if _err != nil {
		panic(_err)
	}
	body, err := json.Marshal(resp.Body)
	if err != nil {
		panic(err)
	}
	fmt.Printf("body: %s\n", string(body))
}

通過Config在初始化Client階段配置請求的代理。

package main

import (
	"encoding/json"
	"fmt"
	"os"

	openapi "github.com/alibabacloud-go/darabonba-openapi/v2/client"
	ecs20140526 "github.com/alibabacloud-go/ecs-20140526/v4/client"
	util "github.com/alibabacloud-go/tea-utils/v2/service"
	"github.com/alibabacloud-go/tea/tea"
)

func main() {
	config := &openapi.Config{
		// 從環境變數擷取RAM使用者的AccessKey ID
		AccessKeyId: tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID")),
		// 從環境變數擷取RAM使用者的AccessKey Secret
		AccessKeySecret: tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET")),
		// Region ID
		RegionId: tea.String("<RegionId>"),
		// 通過Config配置代理
		HttpProxy:  tea.String("http://127.0.0.1:9898"),
		HttpsProxy: tea.String("http://user:password@127.0.0.1:8989"),
		NoProxy:    tea.String("127.0.0.1,localhost"),
	}
	client, _err := ecs20140526.NewClient(config)
	if _err != nil {
		panic(_err)
	}
	describeRegionsRequest := &ecs20140526.DescribeRegionsRequest{}
	// 建立RuntimeObject執行個體並設定運行參數。
	runtime := &util.RuntimeOptions{}
	resp, _err := client.DescribeRegionsWithOptions(describeRegionsRequest, runtime)
	if _err != nil {
		panic(_err)
	}
	body, err := json.Marshal(resp.Body)
	if err != nil {
		panic(err)
	}
	fmt.Printf("body: %s\n", string(body))
}
