python - 如何修复返回 TypeError 的 Python 代码：'str' object is not callable？

问题描述

我一直在尝试使用（第一次使用它）发送一个POSTHTTP 请求，它一直返回一个PythonTypeError: 'str' object is not callable

我的代码：

import requests
import json

c100 = "100";
url ="http://api.orange.com/smsmessaging/v1/outbound/tel+21654614211/requests"

payload = {
  "outboundSMSMessageRequest": {
    "address": "tel+21653424499",
    "outboundSMSTextMessage": {
      "message": "Capteur "+ c100 +"  est en incendie"
    },
    "senderAddress": "tel+21654614211",
    "senderName": "GCI"
  }
}
headers = {'content-type': 'application/json'}
r = requests.post(url, auth=('Basic <omitted>'), data=json.dumps(payload), headers=headers)

输出：

Traceback (most recent call last):
  File "main.py", line 18, in <module>
    r = requests.post(url, auth=('Basic U0cwUE1aeGZmZ0JLbUkzWUV2ZWlsM0xBdEt0UVZ4Q1k6SVRqWXQxRU5nWlV4SGM5OQ=='), data=payload, headers=headers)
  File "/usr/lib/python3/dist-packages/requests/api.py", line 88, in post
    return request('post', url, data=data, **kwargs)
  File "/usr/lib/python3/dist-packages/requests/api.py", line 44, in request
    return session.request(method=method, url=url, **kwargs)
  File "/usr/lib/python3/dist-packages/requests/sessions.py", line 433, in request
    prep = self.prepare_request(req)
  File "/usr/lib/python3/dist-packages/requests/sessions.py", line 371, in prepare_request
    hooks=merge_hooks(request.hooks, self.hooks),
  File "/usr/lib/python3/dist-packages/requests/models.py", line 291, in prepare
    self.prepare_auth(auth, url)
  File "/usr/lib/python3/dist-packages/requests/models.py", line 470, in prepare_auth
    r = auth(self)
TypeError: 'str' object is not callable

解决方案

您的身份验证是错误的，而且问题是：您是否需要身份验证？

基本身份验证许多需要身份验证的 Web 服务都接受 HTTP 基本身份验证。这是最简单的一种，Requests 直接支持它。

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]>

事实上，HTTP Basic Auth 是如此普遍，以至于 Requests 提供了一个方便的简写方式来使用它：

>>> 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。

笔记：

如果你有令牌，你可能需要类似的东西：

import requests

auth_token='sdasadadsadas'
head = {'Authorization': 'Bearer ' + auth_token}
payload = {
  "outboundSMSMessageRequest": {
    "address": "tel+21653424499",
    "outboundSMSTextMessage": {
      "message": "Capteur "+ c100 +"  est en incendie"
    },
    "senderAddress": "tel+21654614211",
    "senderName": "GCI"
  }
}

url = 'http://api.orange.com/smsmessaging/v1/outbound/tel+21654614211/requests'
response = requests.post(url,  json = payload, headers=head)
