回答您的问题

from .templatetags.CoinbaseWalletAuth import CoinbaseWalletAuth

def test(request):
 if request.method == 'POST':
      api_url = 'https://api.coinbase.com/v2/'
      auth = CoinbaseWalletAuth # call the class based function in views(This is not working)
      r = requests.get(api_url + 'user', auth=auth)
      data= r.json()
      return HttpResponse(data)

使用templatetags的要点是在渲染模板时运行somelogic ...在您的视图中，您已经可以使用python编写逻辑，如果您必须在应用程序中使用templatetag的某些逻辑，那么您应该将其编写为方法（类，静态或其他方法），并在您的templatetag中调用此方法...，以便您可以在应用之间共享此逻辑

在您项目的某些文件中（可能是模型，也可能是实用程序）

CoinbaseWalletAuth.py

API_KEY = '******************'
API_SECRET = '***************'

class CoinbaseWalletAuth(AuthBase):
    def __init__(self, api_key, secret_key):
        ...

    def __call__(self, request):
        ...
        return request

coinbase_templatetag.py

from django import template
from .utils import CoinbaseWalletAuth # utils will the folder that you store that file

register = template.Library()

register.tag('CoinbaseWalletAuth', CoinbaseWalletAuth(API_KEY,API_SECRET))

如何在Django中的views.py中调用基于类的模板标签？
