Not getting headers in response for android client

[kpradeepkumarreddy]

Description

I have generated code for android client that uses volley library. I want to get headers from response. How can i get the headers from the response ???

Swagger-codegen version

swagger-codegen-cli-2.2.1.jar

Swagger declaration file content or url

 paths:
   /login:
    post:
      summary: send mobileNum and otp to login
      description: send mobileNum and otp to login
      parameters:
       - name: args
         in: query
         description: send mobileNum and otp in args 
         required: true
         type: string
         format: string
     tags:
       - login
     responses:
       '200':
         headers:
           Authorization:  
             description: access token will be set in the authorization header
             type: string
         description: login successful, received accessToken in header and refreshToken in body
         schema:
           $ref: '#/definitions/ResponseTO'
     ```

 ##### Command line used for generation
java -jar swagger-codegen-cli.jar generate -i login1.yml -l android --library=volley -o login-source-code/ -c config.json

=> for adding header to the request, i can use the following code,
     LoginApi loginApi = new LoginApi();
     loginApi.addHeader(String key, String value)

=> How can i get the headers from the response ??????

@kpradeepkumarreddy there should be a WithHttpInfo method (for every endpoint) to get the response headers as well as status code.

If you need further help, let us know. Closing the issue for the time being.

Can you please explain your answer little more elaborately with an example.
In the above yaml file, the end point is /login. I don't see any method with WithHttpInfo().
I'm actually clueless about how to get it to work.

Yes my company is using Swagger Codegen. I have added my company name to the list.

@kpradeepkumarreddy my bad. We've not yet added that (WithHttpInfo method) to the Android (Volley) API client. Please use the Java API client which comes with the WithHttpInfo: https://github.com/swagger-api/swagger-codegen/wiki/FAQ#how-can-i-generate-an-android-sdk

For example:
addPet
addPetWithHttpInfo

can you please add the WithHttpInfo() method to the android(volley). Because, till now i was using android(volley) and i know how to use the code generated for android(volley). Now when i generated the code for java (retrofit2 or okhttp-gson), the generated code is different from what is generated for android(volley). Now with this newly generated code, i don't know how to make a request and get the responses.

using android(volley) generated code i used to make the request and get response as follows:-

ApiInvoker.initializeInstance();

LoginApi loginApi = new LoginApi();
LoginTO requestArgs = new LoginTO();
requestArgs.setMobileNum(mobileNum);
requestArgs.setOtp((String) params[0]);

Gson gson = new Gson();
String reqArgStr = gson.toJson(requestArgs);

ResponseTO responseTO = loginApi.loginPost(reqArgStr);

=> Now the generated code for java(retrofit2 or okhttp-gson) is different. I don't know how to use this code.

[wing328]

For Java (okhttp-gson) API client, it comes with documentation and the README.md is a good starting point.

can you please add the WithHttpInfo() method to the android(volley). Because, till now i was using android(volley) and i know how to use the code generated for android(volley).

May I know if you've time to contribute the enhancement? If yes, I can show you some good starting points.
