As shown below:

import urllib,json,requests
url = 'http://127.0.0.1:8000/account/login'
headers = {}
data = {'username':'asd','pwd':'123456$'}
request = requests.post(url=url, data=data,json=True . headers=headers)
response = request.content.decode()
# Those that need to carry the request header can all be written in headers Inside, data Is the request body, need to carry additional information can also be added
print(response)
#1 Under normal circumstances, you can successfully request the return value

If the request fails, it is a cross-domain problem or a parameter error.
