Question

我有一部法典,可以与HttpsUrlConnection一起执行《社会、文化权利国际公约》中的要求,但该法典的某些使用者拥有一个封闭的用户组的SIM卡,他们需要在自己身上设置代理。如果他们确定代理人,就需要修改我的代码。我对此表示担忧:

    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();
}

我现在收到错误:

javax.net.ssl.SSLException:链接由同行关闭

如果使用尿液。开放Connection () wuithout Proxy and without Proxyppings in the apn, the Code work, what may be the Problem?

Answer 1

您可以尝试这种登记代理服务器的替代方式:

Properties systemSettings=System.getProperties();

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

Answer 2

您可使用NetCipher的图书馆,在使用时,便利代位和现代TLS config。电话:NetCipher.setProxy() ,以建立全球对应代理。 NetCipher also configures the HttpsURLConnection instance to use the better support TLS edition,movs SSLv3 support, and configures the Bestripe of ciphers for that TLS edition. 首先,在build.gradle上添加:

compile  info.guardianproject.netcipher:netcipher:1.2

或您可下载netcipher-1.2.jar,并直接列入您的附录。然后,不要说:

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

呼吁:

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