V2.0 Java SDK如何配置网络代理 - 阿里云SDK

本文为您介绍V2.0 Java SDK对于代理的配置方式。

代理配置方式

说明

代理配置优先级：RuntimeOption配置>Client配置，优先级依次降低。

支持通过运行时参数（RuntimeOptions）配置当前请求的代理。

import com.aliyun.ecs20140526.Client;
import com.aliyun.ecs20140526.models.DescribeRegionsRequest;
import com.aliyun.teaopenapi.models.Config;
import com.aliyun.teautil.models.RuntimeOptions;

public class Sample {
    public static void main(String[] args) throws Exception {
        Config config = new Config();
        // 从环境变量获取RAM用户的AccessKey ID
        config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        // 从环境变量获取RAM用户的AccessKey Secret
        config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
        // 地域ID
        config.setRegionId("<regionId>");
        Client client = new Client(config);

        // 运行时参数设置，仅对使用了该运行时参数实例的请求有效
        RuntimeOptions runtimeOptions = new RuntimeOptions();
        runtimeOptions.httpProxy = "http://127.0.0.1:9898";
        runtimeOptions.httpsProxy = "http://user:password@127.0.0.1:8989";
        runtimeOptions.noProxy = "127.0.0.1,localhost";

        DescribeRegionsRequest describeRegionsRequest = new DescribeRegionsRequest();

        client.describeRegionsWithOptions(describeRegionsRequest, runtimeOptions);
    }
}

支持通过Config在初始化Client阶段设置请求的代理。

import com.aliyun.ecs20140526.Client;
import com.aliyun.ecs20140526.models.DescribeRegionsRequest;
import com.aliyun.teaopenapi.models.Config;
import com.aliyun.teautil.models.RuntimeOptions;

public class Sample {
    public static void main(String[] args) throws Exception {
        Config config = new Config();
        // 从环境变量获取RAM用户的AccessKey ID
        config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        // 从环境变量获取RAM用户的AccessKey Secret
        config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
        // 地域ID
        config.setRegionId("<regionId>");
        // Client代理参数设置
        config.setHttpProxy("http://127.0.0.1:9898");
        config.setHttpsProxy("http://user:password@127.0.0.1:8989");
        config.setNoProxy("127.0.0.1,localhost");
        Client client = new Client(config);

        RuntimeOptions runtimeOptions = new RuntimeOptions();
        DescribeRegionsRequest describeRegionsRequest = new DescribeRegionsRequest();

        client.describeRegionsWithOptions(describeRegionsRequest, runtimeOptions);
    }
}
