0x01 Django

• Build a Blog Application

  • Sending e-mails with Django

    • 发送邮件的话，需要一个本地的 SMTP 服务器或者 网络 SMTP 服务器

  • 网络 STMP 服务器的话，需要在 settings.py 中添加：

    • EMAIL_HOST : SMTP 服务器主机，默认 localhost
    • EMAIL_PORT : SMTP 接口，默认25
    • EMAIL_HOST_USER : 用户名
    • EMAIL_HOST_PASSWORD : 密码
    • EMAIL_USE_TLS : 是否用 TLS 安全连接
    • EMAIL_USE_SSL : 是否用 SSL 安全连接
    • 例如，添加:

      EMAIL_HOST = 'smtp.163.com'
      EMAIL_HOST_USER = 'your_account'
      EMAIL_HOST_PASSWORD = 'your_password'
      EMAIL_PORT = 25
      EMAIL_USE_TLS = True
    

    • 调用命令行，可以测试发送功能是否成功
    • python manage.py shell

      >>> from django.core.mail import send_mail
      >>> send_mail('Django mail', 'Test!!!!', 'your_account@163.com', ['recipient@xxx.com']， fail_silently=False)

    • fail_silently 这个参数可以回显发送是否成功，成功返回 1，失败的话，返回异常
    • 将上面的代码，添加到 views.py 中

      from django.core.mail import send_mail
      from .forms import EmailPostForm
    
      def post_share(request, post_id):
          # 通过id检索post内容
          post = get_object_or_404(Post, id=post_id, status='published')
          sent = False
    
          if request.method == 'POST':
              # 表单已提交
              form = EmailPostForm(request.POST)
              if form.is_valid():
                  # 表单字段合法
                  cd = form.cleaned_data
                  post_url = request.build_absolute_uri(post.get_absolute_url())
                  subject = '{} ({}) recommends you reading "{}"'.format(cd['name'], cd['email'],                            post.title)
                  message = 'Read "{}" at {}\n\n{}\'s comments: {}'.format(post.title, post_url, cd['name'], cd['comments'])
                  send_mail(subject, message, 'your_account@163.com', [cd['to']])
                  sent = True
          else:
              form = EmailPostForm()
          return render(request, 'blog/post/share.html', {'post': post, 'form': form, 'sent': sent})

    • 上面定义了一个参数 sent ，如果发送了则为 True，否则 False，这个参数会在之后的 html 模板中出现
    • 视图完成后，还需要在 blog/urls.py 中添加一个 URL pattern

      urlpatterns = [
          # ...
          url(r'^(?P<post_id>\d+)/share/$', views.post_share, name='post_share'),
      ]
