Android的Http请求ClientProtocolException [英] Android Http request ClientProtocolException

问题描述

我有一个似乎是工作完美的，当我使用Firefox的REST客户端或谷歌Chrome浏览器的简单的REST客户端测试它的API
然而，当我使用Android SDK中发送HTTP请求我得到以下异常：

I have an API that seems to be working perfect when I test it using Firefox's "REST Client" or Google Chrome's "Simple REST Client" However, when I send an Http request using Android SDK I get the following exception:

ClientProtocolException：服务器没有一个有效的HTTP响应响应

ClientProtocolException: the server failed to respond with a valid HTTP response

还当我测试使用谷歌Chrome浏览器的高级REST客户端我得到了一个空的响应，所以什么可能会导致此任何想法？

also when I test using Google Chrome's "Advanced REST client" I got an empty response, so any idea about what might be causing this ?


DefaultHttpClient的HttpClient =新DefaultHttpClient（）;结果
HTT presponse HTT presponse = NULL;结果
HttpPost httpPost =新HttpPost（Constants.URL）;结果
httpPost.setHeader（内容类型，应用/ JSON）;结果
httpPost.setHeader（接受，应用/ JSON）;结果
StringEntity SE =新StringEntity（参数，可以HTTP.UTF_8）;结果
httpPost.setEntity（SE）;结果
httpClient.execute（httpPost）;


推荐答案

这应该工作

HttpParams httpParams=new BasicHttpParams();
DefaultHttpClient httpClient = new DefaultHttpClient(httpParams);
HttpResponse httpResponse = null;
HttpPost httpPost = new HttpPost(Constants.URL);
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept", "application/json");
StringEntity se = new StringEntity(params,HTTP.UTF_8);
httpPost.setEntity(se);
httpClient.execute(httpPost);
