how to pass header in retrofit 1.9 API

Question

Requirement->

To get list of Objects Using GET Request:

passing Request headers:

X-ACCESS-TOKEN = Token received after successful sign in

X-USER-EMAIL = Email used in login.

I am using this code to login->

private void normalLoginToServer() {
    final ProgressDialog progressDialog = GeneralUtil.createProgressDialog(this, "Logging into app..");
    progressDialog.show();

Instead of using JSONObject, i need to pass Request Headers.
in a below Astrike code. how to pass Headers.? please help me.

    ***JSONObject outer_body = new JSONObject();
    JSONObject body = new JSONObject();
    try {
        body.put(Constants.USER_EMAIL, _emailText.getText().toString().trim());
        body.put(Constants.USER_PWD, _passwordText.getText().toString().trim());

        outer_body.put(Constants.USER, body);***

        try {
            TypedInput typedInput = new TypedByteArray("text/plain", outer_body.toString().getBytes("UTF-8"));

            apiService.loginToServer(typedInput, new Callback<UserInfo>() {
                @Override
                public void success(UserInfo response, Response response2) {
                    int status = response2.getStatus();
                    switch (status) {
                        case 200:
                            if (progressDialog.isShowing())
                                progressDialog.dismiss();
                            if (response == null)
                                return;
                            String status1 = response.getStatus();
                            if (status1.equalsIgnoreCase("success")) {
                                Toast.makeText(context, "Successful login", Toast.LENGTH_SHORT).show();
                                Data data = response.getData();
                                User user = data.getUser();
                                String token = user.getAccess_token();

                                Intent intent = new Intent(context, MainActivity.class);
                                intent.putExtra(Constants.ACCESS_TOKEN, token);
                                startActivity(intent);
                                finish();
                            } else if (status1.contains("failure")) {
                                Toast.makeText(context, "Username not found", Toast.LENGTH_SHORT).show();
                            }
                            break;

                        case 500:
                            Toast.makeText(context, getResources().getString(R.string.server_error), Toast.LENGTH_SHORT).show();

                    }
                }

                @Override

Answer 1

Assuming you want to pass static headers(those who won't change for a individual requests). for example this code adds cache control header to /tasks request

public interface UserService {  
    @Headers("Cache-Control: max-age=640000")
    @GET("/tasks")
    List<Task> getTasks();
}

and if you need to pass dynamic headers (those changing on individual requests)

public interface UserService {  
    @GET("/tasks")
    List<Task> getTasks(@Header("Content-Range") String contentRange);
}

You can use @Header in your retrofit api interface. For example, something like:

void loginToServer(@Header("your_header") String yourHeaderValue, Callback<UserInfo> callback);
