HttpClient 4.2.3 - 连接重置异常

标签： java apache java-ee apache-httpclient-4.x

我正在开发一个应用程序，使用Apache HttpClient 4.2.3发送带URL参数的https POST请求。我必须在POST请求中发送URL参数，如“？username = abc”。我正在获得连接重置异常。我不知道为解决这个问题需要解决的问题。如果有人帮我解决这个问题，我会很高兴的。

“httpClient.execute（httpPost）;”时抛出“连接重置”异常代码被执行。

以下是获取httpClient的代码：

    .  .. . . . . .. . . . .
    System.out.println("--Enter HttpClient.getSSLHttpClient--");

    // a trust manager that trusts everything
    X509TrustManager allTrustManager = new AllTrustManager();

    // SSLContext
    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, new TrustManager[] { allTrustManager }, null);

    SSLSocketFactory sslSocketFactory = new SSLSocketFactory(sslContext);
    Scheme httpsScheme = new Scheme("https", port,sslSocketFactory);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(httpsScheme);

    ClientConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);

    //System.out.println("--Exit HttpClient.getSSLHttpClient--");

    DefaultHttpClient httpClient = new DefaultHttpClient(cm,getHttpParams());

    System.out.println("--Exit HttpClient.getSSLHttpClient--");

    return httpClient;  
    .  .. . . . . .. . . . .



Here is the stake trace:

2 个答案:

答案 0 :(得分：1)

最后，我找到了解决方案。我提到过我使用过HttpClient 4.2.3。以前，我使用以下代码来获取HttpPost对象：

HttpPost httpPost = new HttpPost("https://xyz.com:443/user?username=abc&password=123");
.. . .. . .
httpClient.execute(httpPost);
..  .. . . . .

并获得“连接重置”例外。

然后我删除了端口并再次尝试。现在，我已成功获得服务器的响应：

HttpPost httpPost = new HttpPost("https://xyz.com/user?username=abc&password=123");
.. . .. . .
httpClient.execute(httpPost);
..  .. . . . .

工作正常，但我还有一个问题： 为什么我在删除端口后成功响应？

答案 1 :(得分：0)

前几天我遇到了同样的问题，我通过移除443端口解决了这个问题。 我仍然不明白为什么会造成问题。问题是，如果我将网址复制/粘贴到浏览器，它就可以正常工作......
