android - 执行 JSON 请求时出现内部错误

Question

我正在开发一个通过 JSON 消息与服务器通信的应用程序。

一些消息已正确发送和接收结果。但是我的一个例程抛出了一个错误，我不确定这是我的问题还是服务器的问题。

错误是:

 org.apache.http.client.HttpResponseException: Internal Server Error
     at org.apache.http.impl.client.BasicResponseHandler.handleResponse(BasicResponseHandler.java:71)
     at org.apache.http.impl.client.BasicResponseHandler.handleResponse(BasicResponseHandler.java:59)

     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626)
     at dalvik.system.NativeStart.main(Native Method)

我要发布的代码是这样的:

    private String post(String json) {
        int TIMEOUT_MILLISEC = 10000; // = 10 seconds
        HttpParams httpParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
        HttpClient client = new DefaultHttpClient(httpParams);

        HttpPost request = new HttpPost(
                "https://my server url");
        try {
            StringEntity entity = new StringEntity(json);
            entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,
                    "application/json"));
            request.setEntity(entity);

            ResponseHandler<String> handler = new BasicResponseHandler();
            return client.execute(request, handler);
        } catch (Throwable e) {
            e.printStackTrace();
            return "";
        }
    }

我阅读了 BasicResponseHandler 文档:

“一个 ResponseHandler，它将响应主体作为成功 (2xx) 响应的字符串返回。如果响应代码 >= 300，则使用响应主体并抛出 HttpResponseException。如果与 {@link org 一起使用.apache.http.client.HttpClient#execute( org.apache.http.client.methods.HttpUriRequest, ResponseHandler), HttpClient 可以在内部处理重定向(3xx 响应)。”

所以现在我认为这是一个服务器端错误。我需要知道到底是哪个错误。

谢谢

您的服务器正在返回 500 Internal Server Error 响应状态。所以问题出在您的服务器上。
