httpClient - ＆gt; HTTP / 1.1 500内部服务器错误

Question

当我尝试使用HttpClient在我的REST客户端应用程序中执行PUT / POST时，我总是收到此错误（ HTTP / 1.1 500内部服务器错误）。

你知道它可能是什么样的错误吗？这不是代码中的错误吗？ 它告诉我在服务器.. 如果你需要我的一些代码，那就请求它！

由于

这是我在服务器日志中收到的消息：

您的服务器收到请求，但处理它的逻辑（如果是java，一个servlet）会导致错误。您必须获取服务器日志并查找堆栈跟踪，错误消息等...

Answer 2

我已经用不同的方式解决了我的问题。

我是这样做的：

    httpPut.addHeader("Accept", "application/json");
    httpPut.addHeader("Content-type", "application/json");

    List <NameValuePair> nvps = new ArrayList <NameValuePair>();

    nvps.add(new BasicNameValuePair("Accept", "application/json"));
    nvps.add(new BasicNameValuePair("Content-Type", "application/json"));

    nvps.add(new BasicNameValuePair("userID", "user1"));
    nvps.add(new BasicNameValuePair("firstName", "teste"));
    nvps.add(new BasicNameValuePair("lastName", "Alves"));

    httpPut.setEntity(new UrlEncodedFormEntity(nvps));

    HttpResponse response = httpclient.execute(httpPut);

现在我这样做了：

        httpPut.addHeader("Content-type", "application/json");
        httpPut.addHeader("Accept", "application/json");

        JSONObject obj = new JSONObject();  
            obj.put("userID", "user1");
            obj.put("firstName", "Antonio");
            obj.put("lastName", "Alves");

        StringEntity se = new StringEntity(obj.toString());
        se.setContentEncoding("UTF-8");
        se.setContentType("application/json");
        httpPut.setEntity(se);

        HttpResponse response = httpclient.execute(httpPut);

一切都很顺利......

如果您尝试使用HTTP标头解决方案的选项不足，请尝试将以下密钥添加到Windows注册表中的Internet Explorer中，如果您看到“内部服务器错误”之前的“没有此类窗口异常”。以下为我解决了这个问题。
