Python “如何修复”；类型错误：'；dict'；对象不可调用"；请求中

我的目标是使用Mailgun发送电子邮件。我使用Flask调用它，使用

请求

库：

contact.py

def index():
  data = request.form.to_dict()
  send_email(data)
  return "Success!"

发送电子邮件（）

我知道这与

send\u email（）

功能有关，但我目前正忙于解决这个问题

您错误地使用了

api

参数。您希望以元组形式传入用户名和密码组合：

Mailgun API确实存在，但要使用

auth

关键字参数发送基本身份验证标头，您可以传入：

使用HTTP Basic Auth发出请求非常简单：

>>> from requests.auth import HTTPBasicAuth
>>> requests.get('https://api.github.com/user', auth=HTTPBasicAuth('user', 'pass'))
<Response [200]>

>>from requests.auth import HTTPBasicAuth
>>>请求。获取（'https://api.github.com/user，auth=HTTPBasicAuth（'user'，'pass'））

事实上，HTTP Basic Auth非常常见，请求为使用它提供了方便的速记：

>>> requests.get('https://api.github.com/user', auth=('user', 'pass'))
<Response [200]>

>>请求。获取（'https://api.github.com/user，auth=（'user'，'pass'））

在这样的元组中提供凭据与上面的

HTTPBasicAuth

示例完全相同

对，所以

auth={“api”：api_KEY}

是字典。那是因为这个。

>>> from requests.auth import HTTPBasicAuth
>>> requests.get('https://api.github.com/user', auth=HTTPBasicAuth('user', 'pass'))
<Response [200]>

>>> requests.get('https://api.github.com/user', auth=('user', 'pass'))
<Response [200]>
