Question

此代码的目标是使用Mailgun发送电子邮件。我正在使用requests库从Flask调用它：

contact.py

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

send_email（）

def send_email(data: dict):
  data = format_data(data)

  return requests.post(
    API_URL,
    auth={ "api": API_KEY },
    data=data,
  )

我知道它与send_email()函数有关，但是我目前仍在解决该问题上。

编辑：这是完整的追溯：

您错误地使用了api参数。您想将用户名和密码组合作为元组传递：

auth=("api", API_KEY),

Mailgun API确实是requires you to pass in the API key as a Basic Auth password，但是要使用auth关键字参数发送基本身份验证标头，则您可以传入HTTPBasicAuth() instance or a tuple：

使用HTTP基本身份验证进行请求非常简单：
>>> from requests.auth import HTTPBasicAuth
>>> requests.get('https://api.github.com/user', auth=HTTPBasicAuth('user', 'pass'))
<Response [200]>
实际上，HTTP基本身份验证非常普遍，因此请求提供了使用它的便捷方式：
>>> requests.get('https://api.github.com/user', auth=('user', 'pass'))
<Response [200]>
在这样的元组中提供凭据与上面的HTTPBasicAuth示例完全相同。

如何修复请求中的“ TypeError：'dict'对象不可调用”
