Generating Clients/SDKs Using Swagger Codegen

I am trying to generate a client using swagger-codegen in aspnetcore. When I generate the client everything gets generated but all the code in the controllers is filled with TODO comments rather than the actual code for the method:

Example:

public virtual IActionResult Login([FromQuery]string clientId, [FromQuery]string clientSecret)

        { 

            //TODO: Uncomment the next line to return response 200 or use other options such as return this.NotFound(), return this.BadRequest(..), ...

            // return StatusCode(200, default(AccessToken));



            //TODO: Uncomment the next line to return response 400 or use other options such as return this.NotFound(), return this.BadRequest(..), ...

            // return StatusCode(400, default(Error));



            //TODO: Uncomment the next line to return response 404 or use other options such as return this.NotFound(), return this.BadRequest(..), ...

            // return StatusCode(404, default(Error));



            string exampleJson = null;

            exampleJson = "{\n  \"access_token\" : \"access_token\",\n  \"token_type\" : \"token_type\",\n  \"expires_in\" : 0\n}";

            

            var example = exampleJson != null

            ? JsonConvert.DeserializeObject<AccessToken>(exampleJson)

            : default(AccessToken);

            //TODO: Change the data returned

            return new ObjectResult(example);

        }

However, when I generate the client using .net starndard, everything gets generated fine and I can consume the API endpoints as documented.

Here is the command I’m running:

swagger-codegen generate -i swagger.json -l aspnetcore -o LookerAPI

Does the swagger file provided by looker (API 3.0) support dotnet core? Seems like it might not be completed yet…

Chat would be better. Where can we get connected in chat. ?

Scott input was valuable and I was able to get swagger.json not I have moved to next level where I am writing the API script to connect looker via python. I was getting the error. The error is very much similar in early post. But I didn’t see any solution on that but people have overcome this.

to answer second question I even ran the curl via terminal and I get similar error which read as

HTTP/1.1 401 Unauthorized

Content-Type: application/json;charset=utf-8

Vary: Accept-Encoding

X-Content-Type-Options: nosniff

Content-Length: 84

@scott.hoover

I am getting 404 error similar well not similar its same as mentioned by @Grayson_Williams. I am not sure how this was solved I am not able to follow the post comment on this clear. Could you please guide me on this?

Hello @scott.hoover -

I am stuck with the python script here. when I run the client side I get below error

William - thanks for your input this was informative but it didn’t help me completely.

Appreciated. This is going to help me in future thou 🙂

@svarun

You could indeed use the github site and hit “Clone or Download”:

I hope this helps!

Hey @svarun ,

It sounds like you might have a firewall between your ssh host and github that is blocking traffic on port 22. Try from a location outside of your internal network.

Cheers,

William

Hello there!

I’m having a similar problem to @scottmdavidson. But, my base_url is already correct syntax. I’m getting an ApiException: (400) error. It only happens when using functions whose method in the response variable is ‘POST’ (create_user, create_user_access_filter). I am able to run anything else that I’ve tried (all_users, all_user_access_filters).

What I mean by response variable whose method is post:

    response = self.api_client.call_api(resource_path, 'POST',

                                        path_params,

                                        query_params,

                                        header_params,

                                        body=body_params,

                                        post_params=form_params,

                                        files=local_var_files,

                                        response_type='User',

                                        auth_settings=auth_settings,

                                        callback=params.get('callback'))

Any thoughts? Thanks!

Hey,

I still received the 404 error but the issue is resolved. You were correct it was a permission issue.

I re-looked (no pun intended) at the info from my original curl query and found the space id from the curl query was different than the space id from the front end application. I contacted the admin and the admin setup new api keys for the “right” account. Thanks for the help!

Ok thanks for the advice.

1. I can see the look in the front end (I created it).

Can you point me in the direction to run the look via curl or tell me the syntax. Below is what I have:

curl https://looker.mycompany:19999/api/3.0/looks/15133/run/csv -H "Authorization: Bearer access_token here"

Hello,

I’m having similar issues to scottmdavidson and I am unable to run a look as I get a 404 error. See code below:

import swagger_client as looker

import os





client_id = os.environ.get('LOOKER_CLIENT_ID')

client_secret = os.environ.get('LOOKER_SECRET_KEY')

#base_url = 'https://looker.mycompany.com:9999/api/3.0/'

base_url = 'https://looker.mycompany.com:19999/api/3.0/'





unauthenticated_client = looker.ApiClient(base_url)

unauthenticated_authApi = looker.ApiAuthApi(unauthenticated_client)





token = unauthenticated_authApi.login(client_id=client_id, client_secret=client_secret)

client = looker.ApiClient(base_url, 'Authorization', 'token ' + token.access_token)



looks = looker.LookApi(client)

looks.run_look(9669,'json')

The error I receive:

ApiException: (404)

Reason: Not Found

HTTP response headers: HTTPHeaderDict({'Server': 'nginx', 'Date': 'Thu, 29 Jun 2017 19:14:36 GMT', 'Content-Type': 'application/json;charset=utf-8', 'Content-Length': '69', 'Connection': 'keep-alive', 'Vary': 'Accept-Encoding', 'X-Content-Type-Options': 'nosniff'})

HTTP response body: {"message":"Not found","documentation_url":"http://docs.looker.com/"}

I can authenticate successfully and receive a token. I tested that access_token in curl and it retrieves my user info successfully. Any help here to run a look would be great!
