发送JSONObject使用HttpConnection POST与黑莓

Question

我试图做一个blackbery应用程序，可以发送JSONObject通过HttpConnection POST请求。 JSONObject是

{ 
    "Contrasena" : "hy1tSPQc3K4IlSZLvd7U7g==", 
    "Plataforma" : "A", 
    "Usuario" : "user2323" 
} 

任何人都知道如何？

Answer 1

您可以使用URLEncodedPostData类。使用像

httpConn.setRequestMethod(HttpConnection.POST); 

    httpConn.setRequestProperty("Content-Type", "application/json"); 

    URLEncodedPostData encPostData = new URLEncodedPostData("UTF-8", false); 

    encPostData.setData(JsonString);//set your jsonstring 

    byte[] postData = encPostData.toString().getBytes("UTF-8"); 

    httpConn.setRequestProperty("Content-Length", String.valueOf(postData.length)); 

    httpConn.openOutputStream().write(encPostData.getBytes()); 

    int Response = httpConn.getResponseCode();
