php curl post请求,java后台用request文件流方式接收

php curl请求：

[php] view plain copy

1. <?php   
2.       
3.             $userid = 'test';  
4.             $key   = 'testkey';  
5.             $sign  = md5($userid.$key);      
6.             $data='data';  
7.             $data_string=json_encode(array('userid'=>$userid,'sign'=>$sign,'data'=>$data));  
8.             $url = "http://xxx.WWW.com/quick/test";  
9.             $ch = curl_init($url);  
10.             curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
11.             curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);//$data JSON类型字符串  
12.             curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
13.             curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data_string)));  
14.             $result = curl_exec($ch);  
15.             echo "<pre>";  
16.             print_r($result);  
17.             echo "</pre>";  
18.             ?>  

java 后台:

[java] view plain copy

1. private static String getRequestStr(HttpServletRequest request) throws Exception {  
2.   
3.       StringBuilder sb = new StringBuilder();  
4.          BufferedReader in=new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8"));  
5.          String line = null;  
6.          while ((line = in.readLine()) != null) {  
7.              sb.append(line);  
8.          }  
9.   
10.      return  sb.toString();  
11.  }
