我怎样才能发送一个json数组到webserver使用凌空？

Question

我可以接收一个json数组，但是如何使用volley发送一个json数组？

JsonArrayRequest arrayReq = new JsonArrayRequest(URL, 
     new Listener<JSONArray>() { 

}

尝试使用下面的代码段实现它，我希望它会工作：

public class JsonPostArrayRequest extends JsonRequest<JSONObject> { 

    JSONArray params; 
    public JsonPostArrayRequest(String url, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener,JSONArray params) { 
     super(Method.POST, url, null, listener, errorListener); 
     this.params=params; 
    } 

    @Override 
    public byte[] getBody() { 
      if (this.params != null && this.params.length() > 0) { 
       return encodeParameters(this.params, getParamsEncoding()); 
      } 
      return null; 

     } 

    private byte[] encodeParameters(JSONArray params, String paramsEncoding) { 
      try { 
       return params.toString().getBytes(paramsEncoding); 
      } catch (UnsupportedEncodingException uee) { 
       throw new RuntimeException("Encoding not supported: " + paramsEncoding, uee); 
      } 
     } 

     @Override 
     protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) { 
      try { 
       String jsonString = 
         new String(response.data, HttpHeaderParser.parseCharset(response.headers)); 
       return Response.success(new JSONObject(jsonString), 
         HttpHeaderParser.parseCacheHeaders(response)); 
      } catch (UnsupportedEncodingException e) { 
       return Response.error(new ParseError(e)); 
      } catch (JSONException je) { 
       return Response.error(new ParseError(je)); 
      } 
     } 
}
