twilio java 与代理身份验证的连接

Question

我正在使用 api 示例 here.

中的示例 Twilio java-sdk 设置 java Twilio 连接

唯一的区别是我需要运行我的 Twilio 连接通过网络代理和身份验证。

还有其他关于通过网络代理连接到 Twilio 的问题，但没有可接受的答案。例如 this，基于这个答案，我尝试实施这样的解决方案：

import com.twilio.sdk.TwilioRestClient;
import com.twilio.sdk.TwilioRestException;
import com.twilio.sdk.resource.factory.MessageFactory;
import com.twilio.sdk.resource.instance.Message;

import org.apache.http.HttpHost;
import org.apache.http.NameValuePair;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.impl.conn.DefaultProxyRoutePlanner;
import org.apache.http.message.BasicNameValuePair;

import java.util.ArrayList;
import java.util.List;

public class Example {

    // Find your Account Sid and Token at twilio.com/console
    public static final String  ACCOUNT_SID = "asdfasdfasdfdasf";
    public static final String  AUTH_TOKEN = "asdfasdfasdfasdf";
    public static final String  PROXY_ADDRESS = "1.2.3.4";
    public static final int     PROXY_PORT = 80;
    public static final String  PROXY_USER = "user";
    public static final String  PROXY_PASSWORD = "password";

    public static void main(String[] args) {

        //Set up Proxy host
        HttpHost proxy = new HttpHost(PROXY_ADDRESS, PROXY_PORT);
        DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);

        //Set up Proxy user credentials
        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
                new AuthScope(PROXY_ADDRESS, PROXY_PORT), 
                new UsernamePasswordCredentials(PROXY_USER, PROXY_PASSWORD));

        //Set up HttpClient with proxy and credentials
        CloseableHttpClient httpClient = HttpClients.custom()
                .setRoutePlanner(routePlanner)
                .setDefaultCredentialsProvider(credsProvider)
                .build();


        TwilioRestClient client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN); 
        client.setHttpClient(httpClient);


        // Build a filter for the MessageList
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("Body", "Hello from Java"));
        params.add(new BasicNameValuePair("To", "+12345678901"));
        params.add(new BasicNameValuePair("From", "+12345678901"));

        MessageFactory messageFactory = client.getAccount().getMessageFactory();

        try {
            Message message;
            message = messageFactory.create(params);
            System.out.println(message.getSid());

        } catch (TwilioRestException e) {
            System.out.println(e.getErrorCode());
            System.out.println(e.getErrorMessage());
            e.printStackTrace();
        }

    }

}

它似乎是通过代理服务器到达 Twilio API 但它每次都 returns 一个 20003 error。（权限被拒绝）

我怀疑 http-client web 代理身份验证正在覆盖 twilio 帐户 SID 和身份验证令牌，但我不确定，或者是否有解决此问题的方法。

我已经三次检查了我自己的帐户 SID 和授权令牌，还尝试使用 Twilio 为该帐户提供的 "testing" SID 和授权令牌，但我得到了相同的结果。

对运行通过网络代理使用 Twilio java-sdk 有什么建议吗？

我正在使用 apache http-client 库 4.5.2

已解决...只需要在代理凭据后添加另一组范围为 api.twilio.com 的凭据：

    //Set up Proxy user credentials
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            new AuthScope(PROXY_ADDRESS, PROXY_PORT), 
            new UsernamePasswordCredentials(PROXY_USER, PROXY_PASSWORD));

    //Set up Twilio user credentials
    credsProvider.setCredentials(
            new AuthScope("api.twilio.com", 443), 
            new UsernamePasswordCredentials(ACCOUNT_SID, AUTH_TOKEN));

我会把它留在这里供后代使用，因为对此有几个问题但没有公认的答案。
