凌空没有要求getParams

凌空没有要求getParams

本文介绍了凌空没有要求getParams()方法为标准的POST请求的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想发布一些参数,我在Android中使用凌空轨API。这是code:

我试着用两个日志语句,一个在 getParams()方法,另一个在 getHeaders()。一个在 getHeaders()的,而另一种是没有记录的。为什么凌空忽略 getParams()方法

  {
// FULL_NAME,电子邮件,密码是私有变量定义为这个类

字符串URL =htt​​p://10.0.2.2:3000/users/sign_up.json;

JsonObjectRequest jsonObjReq =新JsonObjectRequest(Request.Method.POST,
                 URL,空,
                 新Response.Listener<的JSONObject>(){

                     @覆盖
                     公共无效onResponse(JSONObject的响应){
                         Log.d(TAG,response.toString());
                         pDialog.hide();
                     }
                 },新Response.ErrorListener(){

                     @覆盖
                     公共无效onErrorResponse(VolleyError错误){
                         VolleyLog.d(TAG,错误:+ error.getMessage());
                         pDialog.hide();
                     }
                 }){

             @覆盖
             公共地图<字符串,字符串> getParams()方法{
                 地图<字符串,字符串> PARAMS =新的HashMap<字符串,字符串>();

                 //这不会出现在日志中
                 Log.d(TAG,它分配PARAMS?);


                 params.put(姓名,full_name.getText()的toString());
                 params.put(电子邮件,email.getText()的toString());
                 params.put(密码,password.getText()的toString());

                 返回PARAMS;
             }
             @覆盖
             公共地图<字符串,字符串> getHeaders()抛出AuthFailureError {

                 //这出现在日志中
                 Log.d(TAG,它分配头?);

                 HashMap的<字符串,字符串>标题=新的HashMap<字符串,字符串>();
                 headers.put(内容类型,应用/ JSON的;字符集= UTF-8);

                 返回头;
             }

         };

        //添加请求,请求队列
        。VHelper.getInstance()addToRequestQueue(jsonObjReq,tag_json_obj);

}
 

解决方案

在地方JsonObjectRequest的使用StringRequest

  StringRequest SR =新StringRequest(Request.Method.POST,网址,新Response.Listener<字符串>(){
        @覆盖
        公共无效onResponse(字符串响应){
            Log.d(TAG,response.toString());
        }
    },新Response.ErrorListener(){
        @覆盖
        公共无效onErrorResponse(VolleyError错误){
            VolleyLog.d(TAG,错误:+ error.getMessage());
            Log.d(TAG,+ error.getMessage()+,+ error.toString());
        }
    }){
        @覆盖
        保护地图<字符串,字符串> getParams()方法{
            地图<字符串,字符串> PARAMS =新的HashMap<字符串,字符串>();
            params.put(ID,28);
            params.put(值,1);

            返回PARAMS;
        }

        @覆盖
        公共地图<字符串,字符串> getHeaders()抛出AuthFailureError {
            地图<字符串,字符串>标题=新的HashMap<字符串,字符串>();
            headers.put(内容类型,应用程序/ x-WWW的形式urlen codeD);
            headers.put(ABC,价值);
            返回头;
        }
    };

        。AppController.getInstance()addToRequestQueue(SR);
 

I am trying to post some parameters to my rails API using Volley in Android. This is the code:

I tried with two log statements, one in getParams() and another in getHeaders(). The one in getHeaders() is logged while the other one is not. Why is volley ignoring getParams()?

{
//full_name,email,password are private variables defined for this class

String url =  "http://10.0.2.2:3000/users/sign_up.json" ;

JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
                 url, null,
                 new Response.Listener<JSONObject>() {

                     @Override
                     public void onResponse(JSONObject response) {
                         Log.d(TAG, response.toString());
                         pDialog.hide();
                     }
                 }, new Response.ErrorListener() {

                     @Override
                     public void onErrorResponse(VolleyError error) {
                         VolleyLog.d(TAG, "Error: " + error.getMessage());
                         pDialog.hide();
                     }
                 }) {

             @Override
             public Map<String, String> getParams() {
                 Map<String, String> params = new HashMap<String, String>();

                 //This does not appear in the log
                 Log.d(TAG,"Does it assign params?") ;


                 params.put("name", full_name.getText().toString());
                 params.put("email",email.getText().toString());
                 params.put("password", password.getText().toString());

                 return params;
             }
             @Override
             public Map<String, String> getHeaders() throws AuthFailureError {

                 //This appears in the log
                 Log.d(TAG,"Does it assign headers?") ;

                 HashMap<String, String> headers = new HashMap<String, String>();
                 headers.put("Content-Type", "application/json; charset=utf-8");

                 return headers;
             }

         };

        // Adding request to request queue
        VHelper.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);

}
解决方案

Using StringRequest in place of JsonObjectRequest

StringRequest sr = new StringRequest(Request.Method.POST, url , new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.d(TAG, response.toString());
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(TAG, "Error: " + error.getMessage());
            Log.d(TAG, ""+error.getMessage()+","+error.toString());
        }
    }){
        @Override
        protected Map<String,String> getParams(){
            Map<String, String> params = new HashMap<String, String>();
            params.put("id", "28");
            params.put("value", "1");

            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String,String> headers = new HashMap<String, String>();
            headers.put("Content-Type","application/x-www-form-urlencoded");
            headers.put("abc", "value");
            return headers;
        }
    };

        AppController.getInstance().addToRequestQueue(sr);
