代理配置

升级版本 SDK 同样也可以通过以下环境变量设置代理：

或者通过 Config 在初始化 Client 阶段设置请求的代理，升级版 SDK 还支持通过运行时参数（RuntimeOption）配置当前请求的代理。优先级：RuntimeOption > Client > 环境变量：

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 com.aliyun.teaopenapi.models.Config();
        // 从环境变量获取RAM账号的AccessKey ID
        config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        // 从环境变量获取RAM账号的AccessKey ID
        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");
        com.aliyun.ecs20140526.Client client = new com.aliyun.ecs20140526.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);
    }
}
