Question

我有一个使用HttpsUrlConnection执行POST请求的代码，代码工作正常，但我的一些用户拥有一个封闭用户组的SIM卡，他们需要在他们的apn设置中设置代理。如果他们设置代理，我需要修改我的代码。我试过这个：

    HttpsURLConnection connection = null;
    DataOutputStream outputStream = null;
    DataInputStream inputStream = null;
    String urlServer = "https://xxx";
    String boundary = "*****";

try {

    URL url = new URL(urlServer);
    SocketAddress sa = new InetSocketAddress("[MY PROXY HOST]",[My PROXY PORT]);
    Proxy mProxy = new Proxy(Proxy.Type.HTTP, sa);

    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;boundary=" + boundary);

    //this is supposed to open the connection via proxy
    //if i use url.openConnection() instead, the code works
    connection = (HttpsURLConnection) url.openConnection(mProxy);

    //the following line will fail
    outputStream = new DataOutputStream(connection.getOutputStream());

    // [...] 

} catch (Exception ex) {
   ret = ex.getMessage();
}

现在我收到错误：

javax.net.ssl.SSLException：由peer
关闭的连接

如果我在apn中使用url.OpenConnection（）wuithout Proxy而没有Proxysettings，代码可以工作，可能是什么问题？

您可以尝试这种注册代理服务器的替代方法：

Properties systemSettings=System.getProperties();

systemSettings.put("http.proxyHost", "your.proxy.host.here");
systemSettings.put("http.proxyPort", "8080"); // use actual proxy port

使用Android的HttpsURLConnection时，您可以使用NetCipher库轻松进行代理设置和现代TLS配置。致电NetCipher.setProxy()以设置应用全局代理。 NetCipher还将HttpsURLConnection实例配置为使用支持最佳的TLS版本，删除SSLv3支持，并为该TLS版本配置最佳密码套件。首先，将其添加到 build.gradle ：

compile 'info.guardianproject.netcipher:netcipher:1.2'

或者您可以下载 netcipher-1.2.jar 并将其直接包含在您的应用中。然后而不是呼叫：

HttpURLConnection connection = (HttpURLConnection) sourceUrl.openConnection(mProxy);

请致电：

NetCipher.setProxy(mProxy);
HttpURLConnection connection = NetCipher.getHttpURLConnection(sourceUrl);
