無法從httpRequest獲取參數

Question

我想將客戶端的字符串傳輸到Web服務器。

客戶端代碼：

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); 

服務器代碼：

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

} 

的服務器輸出「空」的控制檯，我希望應該是「Hello服務器」，每次的客戶端請求httpPut。這是如何造成的，我該如何解決這個問題。

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);
