httpclient () post a wonderful question!

httpclient () post http android

 private String connServerForResult (String path, String contents) {
/ / TODO Auto-generated method stub 
HttpClient client = new DefaultHttpClient (); 
String json = null; 

try {
/ / Destination address 
HttpPost request = new HttpPost (path); 
/ / Constructor string data 
StringEntity entity = new StringEntity (contents); 
/ / Set the type 
entity.setContentType ("application / x-www-form-urlencoded"); 

entity.setContentEncoding (new BasicHeader (HTTP.CONTENT_ENCODING, HTTP.UTF_8)); 
Data 
 / / Set requestrequest.setEntity (entity); 
/ / Execute 
HttpResponse response = client.execute (request); 
HttpEntity httpentity = response.getEntity (); 
/ / Result 
json = EntityUtils.toString (httpentity); 
System.out.println ("account" + json); 
} Catch (Exception e) {
e.printStackTrace (); 
} 
return json; 
} 
}; 

This is the code! When tested post no problem! But the real address changed after the server can not obtain the data I post up! Can return an error message! This is what ah? (Server code is the same)

Determine under your server address is correct, see what type of error return. Whether the server receives a request

respones can see the code, and a code to see what is wrong, and then re-check the correctness of combining url
