Python请求：从返回的JSON字符串中获取属性

本文介绍了Python请求：从返回的JSON字符串中获取属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 import requests r = requests.get('httpbin/get'); r.text

返回：

u'{\n "url": "httpbin/get",\n "headers": {\n "Host": "httpbin",\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']
