推荐答案
可能会帮助您:
使用MultiValueDict的get方法.这也出现在标准字典上,并且是一种在不存在默认值的情况下获取值的方法.
Use the MultiValueDict's get method. This is also present on standard dicts and is a way to fetch a value while providing a default if it does not exist.
username = request.POST.get("username", False)
password = request.POST.get("password", False)
