如何发布json数组对象在服务器上使用volley库在android ..？

Question

您好，我希望在服务器上发布这个[{“name”：“fdfdfdfdfdfdfdfdfdfdfdfdf”]}简单数组。使用凌空libray IM， 请求方法是POST， DATAFORMAT是数组，

任何人都可以解释我这样做..？

这为我工作 1.创建一个新的Java类

package com.hudutech.hakiki.hfarm; 

import com.android.volley.NetworkResponse; 
import com.android.volley.ParseError; 
import com.android.volley.Response; 
import com.android.volley.toolbox.HttpHeaderParser; 
import com.android.volley.toolbox.JsonRequest; 

import org.json.JSONArray; 
import org.json.JSONException; 
import org.json.JSONObject; 

import java.io.UnsupportedEncodingException; 

/** 
* Created by New LAptop on 10/03/2017. 
*/ 
public class JsonPostArrayRequest extends JsonRequest<JSONObject> { 

    JSONArray params; 
    public JsonPostArrayRequest(String url,JSONArray params, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) { 
     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)); 
     } 
    } 
} 

呼叫要发布阵列

JsonPostArrayRequest req = new JsonPostArrayRequest(Paths.register_animal_url,obj, new Response.Listener<JSONObject>() { 
    @Override 
    public void onResponse(JSONObject response) { 
     //Toast.makeText(getApplicationContext(), response.getString("message")+poultry_kind, Toast.LENGTH_LONG).show(); 
     dialog.hide(); 
     try{ 
     Toast.makeText(getApplicationContext(), response.getString("message"), Toast.LENGTH_LONG).show(); 
     VolleyLog.v("Response:%n %s", response.toString(4)); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 
    } 


}, new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError volleyError) { 
     // Handle error 
     VolleyLog.e("Error: ", volleyError.getMessage()); 
     String message = null; 
     if (volleyError instanceof NetworkError) { 
      message = "Cannot connect to Internet...Please check your connection!"; 
     } else if (volleyError instanceof ServerError) { 
      message = "The server could not be found. Please try again after some time!!"; 
     } else if (volleyError instanceof AuthFailureError) { 
      message = "Cannot connect to Internet...Please check your connection!"; 
     } else if (volleyError instanceof ParseError) { 
      message = "Parsing error! Please try again after some time!!"; 
     } else if (volleyError instanceof NoConnectionError) { 
      message = "Cannot connect to Internet...Please check your connection!"; 
     } else if (volleyError instanceof TimeoutError) { 
      message = "Connection TimeOut! Please check your internet connection."; 
     } 
     Toast.makeText(getApplicationContext(), message,Toast.LENGTH_LONG).show(); 
     dialog.dismiss(); 
    } 
}); 

类MySingleton.getInstance（getApplicationContext（））addToRequeue（REQ）。

这可能是一个迟到的答案，但可能有助于某人。
