Python请求：从返回的JSON字符串中获取属性 [英] Python requests: get attributes from returned JSON string

问题描述

import requests
r = requests.get('http://httpbin.org/get');
r.text

返回：

u'{\n  "url": "http://httpbin.org/get",\n  "headers": {\n    "Host": "httpbin.org",\n    "Accept-Encoding": "gzip, deflate, compress",\n    "Connection": "close",\n    "Accept": "*/*",\n    "User-Agent": "python-requests/2.2.1 CPython/2.7.5 Windows/7",\n    "X-Request-Id": "db302999-d07f-4dd6-8c1e-14db45d39fb0"\n  },\n  "origin": "61.228.172.190",\n  "args": {}\n}'

如何获得 origin 和 headers / Host 值？

谢谢

推荐答案

返回的是 JSON 字符串;你需要先解析它才能方便地使用它。如果您拨打 r.json（）而不是 r.text ，请求可以为您执行此操作。

What's being returned is a JSON string; you need to parse it before you can conveniently use it. Requests can do this for you if you call r.json() instead of r.text.

然后这只是做的事情：

resp = r.json()
print resp['origin']
print resp['headers']['Host']
