这是分装好的一个发送请求的方法
/**
* 基于Gson的网络Volley请求(新接口返回数据格式Volley请求)
*
* @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);
}
这是一个业务方法 求大神指导为什么POST请求参数没有传过去 ？在线等！！！1
