我正在与Parsley.js和Django建立前端用户身份验证检查。 这是我的观点

@requires_csrf_token
def password_check(request):
    email = request.POST.get('email')
    password = request.POST.get('password1')
    user = authenticate(email=email, password=password)

    if request.is_ajax():
        if user and user.is_active:
            res = "These password and e-mail are ok."
            ajax_vars_login = {'response': res, 'email': email, 'password': password}
            json_data_login = json.dumps(ajax_vars_login)
        else:
            res = "The e-mail or the password field aren't correct."
            ajax_vars_login = {'response': res, 'email': email, 'password': password}
            json_data_login = json.dumps(ajax_vars_login)

        return HttpResponse(json_data_login, content_type='application/json')

这是欧芹验证员:

Parsley.addAsyncValidator(
  'emailPwCombination', function (xhr) {
       var password = $('#password').parsley();
       var email = $('#email').parsley();
       var response = xhr.responseText;
       var jsonResponse = JSON.parse(response);
       var jsonResponseText = jsonResponse["response"];

       if(jsonResponseText == 'These password and e-mail are ok.')
           return true;
       if(jsonResponseText == '404')
           return false;
  }, '/password_check/'
);

问题是电子邮件似乎没有发送到服务器,因为每当我按下提交时,我都会得到两个xhr响应。
第一反应:

{password: null, response: "The e-mail or the password field aren't correct.",…}
email: "example@gmail.com"
password: null
response: "The e-mail or the password field aren't correct."

第二个回复:

{password: "examplepassword", response: "The e-mail or the password field aren't correct.", email: null}
email: null
password: "examplepassword"
response: "The e-mail or the password field aren't correct."

我错过了什么?

此代码位于异步验证器中,因此每次在值上调用.parsley()时,它都会将其发送到后端。因此,您将收到两个单独的请求,一个仅包含电子邮件,另一个只包含密码。

我认为你不明白什么是欧芹。它是根据一系列标准验证各个领域的;而不是将完整形式的数据发送到后端进行处理。这可以通过几行基本的jQuery非常简单地完成,这里根本不需要欧芹。
