一.requests
Python标准库中提供了：urllib、urllib2、httplib等模块以供Http请求，但是，它的 API 太渣了。它是为另一个时代、另一个互联网所创建的。它需要巨量的工作，甚至包括各种方法覆盖，来完成最简单的任务。
Requests 是使用 Apache2 Licensed 许可证的 基于Python开发的HTTP 库，其在Python内置模块的基础上进行了高度的封装，从而使得Pythoner进行网络请求时，变得美好了许多，使用Requests可以轻而易举的完成浏览器可有的任何操作。
1、GET请求
#<1>、GET请求 #1、无参数实例 ret=requests.get("https://github.com/timeline.json") print (ret.url) #输出：https://github.com/timeline.json print (ret.text) #输出：{"message":"Hello there, wayfaring stranger. If you’re reading this then you probably didn’t see our blog post a couple of years back announcing that this API would go away: http://git.io/17AROg Fear not, you should be able to get what you need from the shiny new Events API instead.","documentation_url":"https://developer.github.com/v3/activity/events/#list-public-events"} # 2、有参数实例 payload = {‘key1‘: ‘value1‘, ‘key2‘: ‘value2‘} ret = requests.get("http://httpbin.org/get", params=payload) print(ret.url) #输出：http://httpbin.org/get?key1=value1&key2=value2 print(ret.text) #输出：{"args":{"key1":"value1","key2":"value2"},"headers":{"Accept":"*/*","Accept-Encoding":"gzip, deflate","Connection":"close","Host":"httpbin.org","User-Agent":"python-requests/2.18.4"},"origin":"182.48.111.194","url":"http://httpbin.org/get?key1=value1&key2=value2"} #<2>、POST请求 #1、基本POST实例 payload={"key1":"value1","key2":"value2"} ret=requests.post("http://httpbin.org/post",data=payload) print (ret.text) #输出：{"args":{},"data":"","files":{},"form":{"key1":"value1","key2":"value2"},"headers":{"Accept":"*/*","Accept-Encoding":"gzip, deflate","Connection":"close","Content-Length":"23","Content-Type":"application/x-www-form-urlencoded","Host":"httpbin.org","User-Agent":"python-requests/2.18.4"},"json":null,"origin":"182.48.111.194","url":"http://httpbin.org/post"} #2、POST请求 import json url=‘https://api.github.com/some/endpoint‘ payload={"some":"data"} headers={‘content-type‘: ‘application/json‘} ret=requests.post(url,data=json.dumps(payload),headers=headers) print (ret.text) # 输出：{"message":"Not Found","documentation_url":"https://developer.github.com/v3"} print (ret.cookies) #输出：<RequestsCookieJar[]> #3、其他请求 requests.get(url, params=None, **kwargs) requests.post(url, data=None, json=None, **kwargs) requests.put(url, data=None, **kwargs) requests.head(url, **kwargs) requests.delete(url, **kwargs) requests.patch(url, data=None, **kwargs) requests.options(url, **kwargs) # 以上方法均是在此方法的基础上构建 requests.request(method, url, **kwargs)
