API Series #2 - Building an API with Flask in Python

[@thomives4353]

I agree with everyone that this video is awesome. However, if you're on linux, I found that I had to add location='values' to the parser.add_argument method calls in the post method -> parser.add_argument('userId', required=True, location='values') . Once I did that, problems solved. The message that I was getting was "{ "message": "Did not attempt to load JSON data because the request Content-Type was not 'application/json'." }"

Hi, James, thank you for the practice. I have a question. The post method works great at 127..0.0.1:5000. However, when I deployed the python flask to IIS, the post method is not working at localhost:port/users?…not sure if I miss anything.

[@JummaJara]

Thank you every much for easy practice, it’s help me a lot to conclude how flask-rest API works. Keep it up!!

Bro, you are an Angel for me, Finally, I learn how to make an API after a couple of months I waste.

[@jamesbriggs]

awesome, happy to help!

This was short, sweet and exactly what I was looking for. Thank you!!

Thanks James, the TDS article is excellent. Having the article to go with the video is really useful👍

18:24 gave me an error without adding location='args' to parser.add_argument().

[@wilrulez811]

Hello! I'm following along and just finished the POST method, but whenever I try to do the command I get a 400 error, even after copy/pasting the code from the article. Help?

[@ianault8599]

I have the same issue, did you find the cause yet?

[@xRays6]

yooo, same error, any solution?

[@ianault8599]

@@xRays6 Yes! parser.add_argument("email", required=False, type=str, location="args") You need to add the location="args" at the end!!! Something to do with Mac and Windows being different I think but with the location="args" it works on everything.

Well explained! Looking forward to part 3.

[@rmunson96]

Getting this error trying to run the code "Object of type method is not JSON serializable" the error is coming from this line return {'data': data}, 200 because the data prints correctly just before this

how to get/post data from/to sql server instead of csv file ?

[@MrLeMarius]

Thanks a lot for this explanation, very clear and will save me a lot of time!

[@zelaTVV]

It's really well explained !

[@mrunalsonawane3363]

Hey! So I wanna build an API with GET and POST methods and with access tokens or API keys. I want to limit functionality of certain keys to only the GET method while some should be able to do both. Can you tell me how I can do that securely?

[@jamesbriggs]

You want to use JSON web tokens (JWT), take a look at this article geekflare.com/securing-flask-api-with-jwt/ This is a good idea for a video though - will be doing this soon, thanks!

[@mrunalsonawane3363]

Great video! Masterfully explained

hi james. is there a flask library for graphql ?

[@jamesbriggs]

I haven't used graphql but it seems there is, can find it here: github.com/graphql-python/flask-graphql

[@stangerdanger7252]

Is there any difference between REST APIs written in Python or others. Like, can we call Python API from Flutter Android app. Is that be a good practice?

[@jamesbriggs]

Internally they are written in another language, but externally they should appear and behave in the exact same way. Eg if I want to communicate with the Twitter/Reddit API, I should be able to use any language and not care about which language they wrote the API in So yes Python API from Flutter Android app is completely fine :)
