【问题描述】：

我正在做一个 django 项目。我是 django 项目，我有一个用于将用户注册到服务的表单。用户注册后，我应该可以向他们发送促销电子邮件。对于发送电子邮件本身，我使用mailchimp。到目前为止，这是我的代码

models.py

class RegistrationModel(models.Model):
    firstName = models.CharField(max_length=200)
    lastName = models.CharField(max_length=200)
    email = models.EmailField(max_length=70)
    phone = models.IntegerField()
    address1 = models.CharField(max_length=200)
    address2 = models.CharField(max_length=200, blank=True)
    city = models.CharField(max_length=200)
    state = models.CharField(max_length=200)
    pincode = models.IntegerField()
    timestamp = models.DateTimeField(auto_now_add=True)

    def publish(self):
        self.save()

    def __str__(self):
        return self.email

forms.py

from .models import RegistrationModel

class RegistrationForm(forms.ModelForm):
    class Meta:
        model = RegistrationModel
        widgets = 
            'firstName': forms.TextInput(attrs='placeholder': 'First Name'),
            'lastName': forms.TextInput(attrs='placeholder': 'Last Name'),
            'email': forms.TextInput(attrs='placeholder': 'Email'),
            'phone': forms.TextInput(attrs='placeholder': 'Phone Number'),
            'address1': forms.TextInput(attrs='placeholder': 'Address1'),
            'address2': forms.TextInput(attrs='placeholder': 'Address2'),
            'city': forms.TextInput(attrs='placeholder': 'City'),
            'state': forms.TextInput(attrs='placeholder': 'State'),
            'pincode': forms.TextInput(attrs='placeholder': 'Pincode'),
        
        fields = ('firstName', 'lastName', 'email', 'phone', 'address1', 'address2', 'city', 'state', 'pincode')

settings.py

MAILCHIMP_API_KEY = 'I have added the api key here'
MAILCHIMP_DATA_CENTER = 'I have added the data center here'
MAILCHIMP_EMAIL_LIST_ID = 'I have added the audience id here'

views.py

from django.conf import settings
from django.shortcuts import render, redirect
from django.core.mail import send_mail
from django.http import HttpResponseRedirect
from .models import RegistrationModel
from .forms import RegistrationForm

import requests, json


MAILCHIMP_API_KEY = settings.MAILCHIMP_API_KEY
MAILCHIMP_DATA_CENTER = settings.MAILCHIMP_DATA_CENTER
MAILCHIMP_EMAIL_LIST_ID = settings.MAILCHIMP_EMAIL_LIST_ID

api_url = f'https://MAILCHIMP_DATA_CENTER.api.mailchimp.com/3.0'
members_endpoint = f'api_url/lists/MAILCHIMP_EMAIL_LIST_ID/members'

def subscribe(email):
    data = 
        "email_address": email,
        "status": 'subscribed'
    

    r = requests.post(
        members_endpoint,
        auth=("", MAILCHIMP_API_KEY),
        data=json.dumps(data),
    )

    return r.status_code, r.json()

def index(request):
    if request.method == "POST":
        form = RegistrationForm(request.POST)

        if form.is_valid():
            RF_qs = RegistraionModel.objects.filter(email=form.instance.email)
            if RF_qs.exists():
                messages.info(request, "You are already subscribed")
            else:
                subscribe(form.instance.email)
                form.save()

        return HttpResponseRedirect(request.META.get("HTTP_REFERER"))

    else:
        form = RegistraionForm()
        context = 'reg_form': form
        return render(request, 'index.html', context)

urls.py

from sample_project import views

urlpatterns = [
    path('', views.index, name='home'),
    path('subscribe/', views.index, name='subscribe'),
    path('about', views.about, name='about'),
    path('contact', views.contact, name='contact'),
]

但是当我在应用程序中提交表单时，什么都没有发生，并且没有填充 mailchimp 中的受众。我不确定我做错了什么。

我正在关注这个video 来创建服务

【参考方案1】：

我认为您需要向 mailchimp 发送一个 json 有效负载，这还需要设置 content-type 标头和接受标头。为此，请更新subscribe 中的调用：

 r = requests.post(
        members_endpoint,
        auth=("", MAILCHIMP_API_KEY),
        json=data,
    )
 print(f'Response to mailchimp call [r.status_code]: r.json()')

【讨论】：

好像没有变化。我还在问题中添加了 urlpatterns。如果你需要看那个

您需要尝试捕获对 request.post 的响应并将其记录到控制台（使用记录器或打印）。

上例中添加。

终端中似乎没有打印任何内容。这可能是因为未调用订阅函数吗？还是网址不对之类的？

是的，这意味着该表单未被发现是有效的。 RegistrationForm 是否与 VittalParivarmodel 而不是 RegistrationModel 模型相关联？
