So I am making a POST JSonObjectRequest to my server and when it is successful everything works and the info is posted, but if there is an error and I try to display it in a toast, it shows up as blank. Here is my request:
private void logUserIn() {
final String URL = Globals.BASE_URL +"/auth/login/";
// Post params to be sent to the server
HashMap<String, String> params = new HashMap<String, String>();
params.put("username", username.getText().toString());
params.put("password", password.getText().toString());
JsonObjectRequest req = new JsonObjectRequest(URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
Log.d("Log In User", response.toString());
//logged in db, changes screens
Intent nextScreen = new Intent(getApplicationContext(), MyProfile.class);
startActivity(nextScreen);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
VolleyLog.e("Error: ", error.getMessage());
}
});
// add the request object to the queue to be executed
Globals.mRequestQueue.add(req);
}
error.getMessage() is always blank. Here is my response (tested using CURL) when the server returns an error:
{ "non_field_errors": [ "Unable to login with provided credentials." ] }
I can't seem to print this message. What am I missing? The POST works but the error response is showing blank...
The VolleyError object has a networkResponse reference, try to check it to see if you can get some useful information from there.
@Override
public void onErrorResponse(VolleyError error) {
if (error == null || error.networkResponse == null) {
return;
}
String body;
//get status code here
final String statusCode = String.valueOf(error.networkResponse.statusCode);
//get response body and parse with appropriate encoding
try {
body = new String(error.networkResponse.data,"UTF-8");
} catch (UnsupportedEncodingException e) {
// exception
}
//do stuff with the body...
}
