public static String XXXPost(String url, String json)throws Exception{
//创建一个DefaultHttpClient的实例
HttpClient httpClient = new DefaultHttpClient();
//创建一个HttpPost对象,传入目标的网络地址:
HttpPost post = new HttpPost(url);
//参数传递
StringEntity postingString = new StringEntity(json);// json传递
postingString.setContentType("application/x-www-form-urlencoded");
//参数传入
post.setEntity(postingString);
//执行execute()方法之后会返回一个HttpResponse对象,服务器所返回的所有信息就保护在HttpResponse里面.
先取出服务器返回的状态码,如果等于200就说明请求和响应都成功了:
HttpResponse response = httpClient.execute(post);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);
return content;
}
