无法从httpRequest获取参数

Question

我想将客户端的字符串传输到Web服务器。

客户端代码：

String uriString = "http://128.128.4.120:8080/GCMService/GCMBroadcast"; 
URI uri = null; 
try { 
    uri = new URI(uriString); 
} catch (URISyntaxException e) { 
    e.printStackTrace(); 
} 
DefaultHttpClient httpClient = new DefaultHttpClient(); 
HttpPut httpPut = null; 
if(uri!=null) 
httpPut = new HttpPut(uri); 
HttpParams params = new BasicHttpParams(); 
params.setParameter("mymsg", "HELLO SERVER"); 
httpClient.setParams(params); 
HttpResponse resp = httpClient.execute(httpPut); 

服务器代码：

@Override 
protected void doPut(HttpServletRequest req, HttpServletResponse resp) 
throws ServletException, IOException {  
    System.out.println(req.getParameter("mymsg")); 

} 

的服务器输出“空”的控制台，我希望应该是“Hello服务器”，每次的客户端请求httpPut。这是如何造成的，我该如何解决这个问题。

String uriString = "http://128.128.4.120:8080/GCMService/GCMBroadcast"; 
URIBuilder uriBuilder = new URIBuilder(uriString); 
uriBuilder.addParameter("mymsg", "HELLO SERVER"); 
DefaultHttpClient httpClient = new DefaultHttpClient(); 
HttpPut httpPut = new HttpPut(uriBuilder.build()); 
HttpResponse resp = httpClient.execute(httpPut);
