DRF：“详细信息”：“未提供身份验证凭据。”

Question

I am new to django rest framework and I am not able to figure out why this is happening.

I guess the problem lies in this particular file. Please help me figuring out the problem.(If any other details files are required let me know)

settings.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

This is the message that I get when I run the server. I looked through the internet stuff, but none got me the solution.

Answer 1

You are using 'rest_framework.authtoken' so you need to send a TOKEN in your request header (Authorization: Token [token]) And I think this web site can be useful for you. :)
