WCF收不到POST传值，求解

[moonface007]

调用方法如下
[OperationContract(Name = "SendMessage")]

[WebInvoke(Method= "POST",ResponseFormat=WebMessageFormat.Json,RequestFormat=WebMessageFormat.Json,UriTemplate = "SendMessage?message={message}", BodyStyle = WebMessageBodyStyle.Wrapped)]

String SendMessage(String message);

JAVA中调用：

HttpPost post = new HttpPost(BASE_URL+"/SendMessage?message=");

List<NameValuePair> value=new ArrayList<NameValuePair>();

value.add(new BasicNameValuePair("message","hello"));

try
{

HttpEntity httpcode=new UrlEncodedFormEntity(value,HTTP.UTF_8);

post.setEntity(httpcode);

HttpResponse httpResponse = client.execute(post);

statusCode = httpResponse.getStatusLine().getStatusCode();

if(statusCode==HttpStatus.SC_OK)

{

result = retrieveInputStream(httpResponse.getEntity());

}

}catch(Exception e)

{

}

可以调用，但String SendMessage(String message);中message值为空
