python - 'method' 对象未找到 django 类型错误

Question

我正在开发 Django 项目，出现以下错误

TypeError at /log_in/
'method' object is not subscriptable
Request Method: POST
Request URL:    http://127.0.0.1:8000/log_in/
Django Version: 1.8.4
Exception Type: TypeError
Exception Value:    
'method' object is not subscriptable
Exception Location: D:\pfd\recom\views.py in log_in, line 95

下面是我的 log_in def

def log_in(request):
    context = RequestContext(request)
    if request.method == 'POST':
        username = request.POST.get['username','']
        password = request.POST.get['password','']
        user = auth.authenticate(username=username, password=password)

    if user is not None:
        if user.is_active:
            auth.login(request,user)
            return HttpResponseRedirect('/loggedin/')
        else:
            return HttpResponse("Inactive user.")
    else:
        return HttpResponseRedirect('error.html')

return render_to_response('error.html')

不明白出了什么问题。

将 request.method 更改为 request.POST。删除上下文时，未检测到帖子，仅执行最后一条语句。

当尝试删除 request.method 时，会出现相同的错误。请帮忙...

Answer 1

您的问题出在以下代码行中:

    username = request.POST.get['username','']
    password = request.POST.get['password','']

应该是

    username = request.POST.get('username','')
    password = request.POST.get('password','')

或者，甚至

    username = request.POST['username']
    password = request.POST['password']

请注意，如果 key 不存在，使用第二种语法会引发异常。
