WebAPI call using volley

Question

I am trying to get access tokens from a server using a Stull String request. I also tried to do a JsonObjectRequest. Both are below.

public void getAuthenticationTokens(Object param1, final CustomListener<String> listener) { //String url = prefixURL + "this/request/suffix"; String url = "https://lw.xxx.co.uk/connect/token"; StringRequest request = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() { @Override public void onResponse(String response) { // response Log.e("Response", response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { // error Log.e("Error.Response", error.networkResponse.toString()); } } ) { @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String,String> params = new HashMap<>(); params.put("Content-Type","application/x-www-form-urlencoded"); //..add other headers return params; } @Override protected Map<String, String> getParams() { Map<String, String> params = new HashMap<String, String> (); params.put("scope", "openid email phone profile offline_access roles"); params.put("resource", "window.location.origin"); params.put("grant_type", "password"); params.put("username", " [e-mail] "); params.put("password", "tempPxxx"); return params; } }; requestQueue.add(request); 

.

 public void getAuthenticationTokens(Object param1, final CustomListener<String> listener) { //String url = prefixURL + "this/request/suffix"; String url = "https://lw.xxx.co.uk/connect/token"; Map<String, Object> jsonParams = new HashMap<>(); jsonParams.put("scope", "openid email phone profile offline_access roles"); jsonParams.put("resource", "window.location.origin"); jsonParams.put("grant_type", "password"); jsonParams.put("username", " [e-mail] "); jsonParams.put("password", "tempPxxx"); JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams), new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { Log.d(TAG + ": ", "somePostRequest Response : " + response.toString()); if(null != response.toString()) listener.getResult(response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { if (null != error.networkResponse) { Log.e(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode); listener.getResult(null); } } }){ @Override public Map<String, String> getHeaders() throws AuthFailureError { // Map<String,String> params = super.getHeaders(); // if(params==null)params = new HashMap<>(); Map<String,String> params = new HashMap<>(); params.put("Content-Type","application/x-www-form-urlencoded"); //..add other headers return params; } }; requestQueue.add(request); 

.

I get the following response from the server:

 E/Volley: [31388] BasicNetwork.performRequest: Unexpected response code 400 for https://lw.xxx.co.uk/connect/token 

.

My colleague, who wrote the server code, asked how to convert the following Angular code (its code that works with the API) to Android.

Can anyone help with this?

 getLoginEndpoint(userName: string, password: string): Observable<Response> { let header = new Headers(); header.append("Content-Type", "application/x-www-form-urlencoded"); let searchParams = new URLSearchParams(); searchParams.append('username', userName); searchParams.append('password', password); searchParams.append('grant_type', 'password'); searchParams.append('scope', 'openid email phone profile offline_access roles'); searchParams.append('resource', window.location.origin); let requestBody = searchParams.toString(); return this.http.post(this.loginUrl, requestBody, { headers: header }); } 

Answer 1

The problem was a few things.

I replaced "params.put (" resource "," window.location.origin ");" with "params.put (" resource "," https://lw.xxx.co.uk ");"

Also, I found out that Volley ignores the overriding of getHeaders, so I commented on this method and used the following to set the headers.

 @Override public String getBodyContentType() { return "application/x-www-form-urlencoded"; } public void getAuthenticationTokens(Object param1, final String userName, final String password, final CustomListener<JSONObject> listener) { String url = "https://lw.xxx.co.uk/connect/token"; StringRequest request = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() { @Override public void onResponse(String response) { // response Log.e("Response", response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { // error Log.e("Error.Response", error.networkResponse.toString()); } } ) { /* @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String,String> params = new HashMap<>(); params.put("Content-Type","application/x-www-form-urlencoded"); //..add other headers return params; }*/ @Override public String getBodyContentType() { return "application/x-www-form-urlencoded"; } @Override protected Map<String, String> getParams() { Map<String, String> params = new HashMap<String, String> (); params.put("scope", "openid email phone profile offline_access roles"); params.put("resource", "https://lw.xxx.co.uk"); params.put("grant_type", "password"); params.put("username", userName); params.put("password", password); return params; } @Override protected VolleyError parseNetworkError(VolleyError response) { try { String json = new String(response.networkResponse.data, HttpHeaderParser.parseCharset(response.networkResponse.headers)); Log.e(TAG, "reponse error = " + json); }catch (Exception e){} return super.parseNetworkError(response); } }; requestQueue.add(request); }//end of getAuthenticationTokens
