使用android/httpclient與流發佈json數據到REST服務

Question

我在將數據發佈到我的REST WCF服務時遇到了一些困難。我需要向它發送一個json對象/數組，但是我的POST方法正在期待一個Stream，然後將它分開以獲取JSON（不能更改此部分）。

我已經在C＃中使用此代碼來實現這一點：

public static string CallPostService(string url, string data) 
    { 
     url = Config.serviceAddress + url; 
     string json = data; 
     byte[] buffer = Encoding.UTF8.GetBytes(json); 
     HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); 
     request.Method = "POST"; 
     request.Credentials = new NetworkCredential("user", "pass"); 
     request.ContentType = "application/x-www-form-urlencoded"; 
     using (StreamWriter sw = new StreamWriter(request.GetRequestStream())) 
     { 
      sw.Write(json); 
      Console.WriteLine(json); 
     } 
     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
     using (StreamReader sr = new StreamReader(response.GetResponseStream())) 
     { 
      string res = sr.ReadToEnd(); 
      return res; 
     } 
    } 

我需要一些相應的Java代碼，要做到這一點，最好是使用Apache的HttpClient。我是http庫的新手，所以我希望有一個方向。

EDITS：

這是從我的WCF服務的方法頭。請求主體需要是一個流，以便服務可以處理它。

[WebInvoke(Method = "POST", UriTemplate = "person/delete", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] 
    Person DeletePerson(Stream streamdata) { //bla }

查看此代碼段。 我真的憑着嘗試過，但它應該工作

public void postData() { 
try {  
// Create a new HttpClient and Post Header 
HttpClient httpclient = new DefaultHttpClient(); 
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php"); 
String auth = android.util.Base64.encodeToString(
(username + ":" + password).getBytes("UTF-8"), 
android.util.Base64.NO_WRAP 
); 
httppost.addHeader("Authorization", "Basic "+ auth); 

    // Add your data 
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
    nameValuePairs.add(new BasicNameValuePair("id", "12345")); 
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!")); 
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

    // Execute HTTP Post Request 
    HttpResponse response = httpclient.execute(httppost); 

} catch (ClientProtocolException e) { 
    // TODO Auto-generated catch block 
} catch (IOException e) { 
    // TODO Auto-generated catch block 
} 
}

 String MyData;// Data need to post to server JSON/XML 
     String reply; 
     try { 

     URLConnection connection = url.openConnection(); 
     HttpURLConnection httppost = (HttpURLConnection) connection; 
     httppost.setDoInput(true); 
     httppost.setDoOutput(true); 
     httppost.setRequestMethod("POST"); 
     httppost.setRequestProperty("User-Agent", "UA Here"); 
     httppost.setRequestProperty("Accept_Language", "en-US"); 
     httppost.setRequestProperty("Content-Type", "content type here"); 
     DataOutputStream dos = new DataOutputStream(httppost.getOutputStream()); 
     dos.write(MyData.getBytes()); // bytes[] b of post data 

     InputStream in = httppost.getInputStream(); 
     StringBuffer sb = new StringBuffer(); 
     try { 
      int chr; 
      while ((chr = in.read()) != -1) { 
       sb.append((char) chr); 
      } 
      reply = sb.toString(); 
     } finally { 
      in.close(); 
     } 

     Log.v("POST RESPONSE",reply); 

    } catch (ClientProtocolException e) { 
    } catch (IOException e) { 
    }
