How to pass credentials using post like username in get method

@patilanup246: credentials are passed in the same way for GET and POST requests.

@patilanup246: use the options provided by Postman for HTTP Basic Authentication.

Thanks Miguel, this was very helpful. Just what i was looking for, well explained and easy to understand.

@ineam how to solve that Unicode error ?

@sskanishk You can just replace it with str in python 3+
if 'title' in request.json and type(request.json['title']) != str:
abort(400)
if 'description' in request.json and type(request.json['description']) is not str:
abort(400)

solved; thanks

Copied the code verbatim. But after curl -u miguel:python -i http://localhost:5000/todo/api/v1.0/tasks
I get the error message:

raise TypeError(repr(o) + " is not JSON serializable")
TypeError: <map object at 0x10a405160> is not JSON serializable

Thank you!
Great tutorial!!

Thank you so much, Miguel, for this wonderful code. Do you happen to have any advice or examples for anyone writing a client for a server like this?

@ronk7 for a JavaScript client I wrote a follow-up tutorial: https://blog.miguelgrinberg.com/post/writing-a-javascript-rest-client. For a Python client use the requests package.

@ronk7 pip install requests

Hey @robinvd, I fixed the issue by wrapping map with list:

return jsonify( { 'tasks': list(map(make_public_task, tasks)) } )

And the same happens with filter:

task = list(filter(lambda t: t['id'] == task_id, tasks))

The fixes are needed for Python3.

Hello,Miguel, sorry for my question about it. I'm beginner in flask , true, I'am front-end developer , but i need learn Flask and write Rest server for my task. But i have error while i copy-paste your code.
If a write request curl -i http://localhost:5000/todo/api/v1.0/tasks/2
I getting Error in JSON , why? Can u help me.
See you soon

@CPPtrueCoder What's the error? You don't have any JSON, so what do you mean by "error in JSON"?

When i get curl -i http://localhost:5000/todo/api/v1.0/tasks/2
From server response {
"error": "Not found"
}
but tasks is available :(

@CPPtrueCoder How do you know it is available? What is the response when you send a request to http://localhost:5000/todo/api/v1.0/tasks?

if request : http://localhost:5000/todo/api/v1.0/tasks then tasks like your guide , but then i try request with ID , i have troubles

(venv) C:\Users\a.rodin\PycharmProjects\flaskProject>curl -i http://localhost:5000/todo/api/v1.0/tasks/1
HTTP/1.0 404 NOT FOUND
Content-Type: text/html; charset=utf-8
Content-Length: 232
Server: Werkzeug/1.0.1 Python/3.8.8

<title>404 Not Found</title>

Not Found

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

i tried rewrite it according updates from comments , but no result , unfortunately

Lol, i changed function :
@app.route('/todo/api/v1.0/tasks/<task_id>', methods=['GET']), instead @app.route('/todo/api/v1.0/tasks/int:task_id', methods=['GET'])
And it's working , but i think it isnt' safely, isn't it ?

@CPPtrueCoder you should use the code as shown above. That is the best. Neither of the two options you posted above matches my code.

Thank you. exactly what i needed as a complete beginner

super useful and straightforward... thanks!!

Thanks, this is helpful, but I do not get the id in the response:

~ curl -u username:password -i http://localhost:5000/todo/api/v1.0/tasks
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 407

{
  "tasks": [
    {
      "description": "Milk, Cheese, Pizza, Fruit, Tylenol",
      "done": false,
      "title": "Buy groceries",
      "uri": "http://localhost:5000/todo/api/v1.0/tasks/1"
    },
    {
      "description": "Need to find a good Python tutorial on the web",
      "done": false,
      "title": "Learn Python",
      "uri": "http://localhost:5000/todo/api/v1.0/tasks/2"
    }
  ]
}

And so I am unable to DELETE it either:

line 102, in delete_task
    if len(task) == 0:
TypeError: object of type 'filter' has no len()

@arafatmohammed you are obviously using different code than what I posted here, so I have no way to tell you what's wrong. Try using my code exactly as shown here.

@miguelgrinberg Thnks for ur great job.
I think you'd better rename this function name to sth better as it conflicts with this function name.
I suggest using def bad_request(error) instead.

Awesome step by step tutorial, Thank you miguel.
