Question

我正在处理Django项目，并出现以下错误

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

以下是我的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')

无法理解错误。

将request.method更改为request.POST。删除上下文时，未检测到帖子，只会执行最后一个语句。

尝试删除request.method时，会显示相同的错误。请帮忙......

您的问题出在以下几行代码中：

    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，如果密钥不存在，使用第二种语法会引发异常。
