post請求-android Volley Post請求參數丟失

android Volley Post請求參數丟失

自定義的Request
package cn.flymeal.androidApp.http;

import java.io.UnsupportedEncodingException;
import java.util.HashMap;
import java.util.Map;

import com.android.volley.AuthFailureError;
import com.android.volley.NetworkResponse;
import com.android.volley.ParseError;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.Response.ErrorListener;
import com.android.volley.Response.Listener;
import com.android.volley.toolbox.HttpHeaderParser;
import com.google.gson.Gson;

/**

• 自定義網絡請求(基於Volley)
• @author zx

• @param
  */
  public class GsonRequest extends Request {

  private static final String PROTOCOL_CHARSET = "utf-8";
  private static final String PROTOCOL_CONTENT_TYPE = String.format(
  "application/json; charset=%s", PROTOCOL_CHARSET);

  private Gson mGson;
  private final Listener mListener;
  private Map mParams=new HashMap(); ;
  private Class mClass;
  private Map headers = new HashMap();

  public GsonRequest(int method, String url, Class cls,
  Map params, Map headers,
  Listener listener, ErrorListener errorListener) {

  super(method, url, errorListener);
  mGson = new Gson();
  mClass = cls;
  mListener = listener;
  mParams = params;
  this.headers = headers;
  

  }

  /**

  • 將返回的數據處理
    */
    @Override
    protected Response parseNetworkResponse(NetworkResponse response) {
    try {
    String jsonString = new String(response.data,
    HttpHeaderParser.parseCharset(response.headers));
    T parseJson = mGson.fromJson(jsonString, mClass);
    return Response.success(parseJson,
    HttpHeaderParser.parseCacheHeaders(response));

    } catch (UnsupportedEncodingException e) {
    return Response.error(new ParseError(e));
    }
    }

  @Override
  protected void deliverResponse(T response) {

  mListener.onResponse(response);
  

  }

  @Override
  public Map getHeaders() throws AuthFailureError {

  return headers != null ? headers : super.getHeaders();
  

  }

  public void setHeaders(Map headers) {

  this.headers = headers;
  

  }

  @Override
  public String getBodyContentType() {

  return PROTOCOL_CONTENT_TYPE;
  

  }

  @Override
  protected Map getParams() throws AuthFailureError {

  return mParams;
  

  }

}
這是分裝好的一個發送請求的方法
/**
* 基於Gson的網絡Volley請求(新接口返回數據格式Volley請求)
*
* @param method
* @param url
* @param params
* @param requestListener
*/
public void executeGsonRequest(int method, String url,
Map params, Map headers,
final RequestListener requestListener) {

    requestListener.onStart();

    request = new GsonRequest<ResponseData>(method, url, ResponseData.class,
            params, headers, new Listener<ResponseData>() {

                @Override
                public void onResponse(ResponseData response) {


                    if (response.getStatus().equals("success")) {

                        requestListener.onSuccess(response.getData());
                        Log.i("volley", response.toString());

                    } else {

                        requestListener.onMessage(response.getMsg());
                    }

                    closeDialog();
                }

            }, new ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {

                    error.printStackTrace();
                    if (error instanceof NetworkError) {
                    } else if (error instanceof ServerError) {
                    } else if (error instanceof AuthFailureError) {
                    } else if (error instanceof ParseError) {
                    } else if (error instanceof NoConnectionError) {
                    } else if (error instanceof TimeoutError) {
                    }
                    requestListener.onError(error);
                    closeDialog();
                }
            });
    requestQueue.add(request);

}

public void checkNum(Context context,String str,RequestListener requestListener){

    UrlParamJoin urlJoin=new UrlParamJoin("mvc/order/api/mobile/submitOrder.do");
    Map<String, String> headers=new HashMap<String, String>();
    headers.put(GlobalConstant.API_VERSION, "v3");
    Map<String, String> param=new HashMap<String, String>();
    param.put("orderStr", str);
    FlymealHttpClient httpClient=new FlymealHttpClient(context);
    httpClient.executeGsonRequest(Method.POST, urlJoin.getUrl(), param, headers, requestListener);

}

這是一個業務方法 求大神指導為什麼POST請求參數沒有傳過去 ？在線等！！！1

最佳回答：

有些版本的volley只支持StringRequest，然後參數以getParams形式傳入，提交方式為GET，樓主試一下吧，應該可以
