GET请求
首先构造一个最简单的get请求，请求的链接为http://httpbin.org/get
import requests 2 r = requests.get("http://httpbin.org/get") 3 print(r.text) #运行结果 { "args": {}, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Host": "httpbin.org", "User-Agent": "python-requests/2.18.4", "X-Amzn-Trace-Id": "Root=1-5f704dcf-78e431abe1d838c6c44e50ac" }, "origin": "58.17.121.223", "url": "http://httpbin.org/get" }
可以发现我们成功的发起了get请求,并且返回结果中包括了请求头，URL,IP等信息
如果发起请求的URL地址需要参数,利用params这个参数
import requests 2 date = { 3 "name":"germey", 4 "age":22 5 } 6 r = requests.get("http://httpbin.org/get",params = date) 7 8 print(r.text) #运行结果 { "args": { "age": "22", "name": "germey" }, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Host": "httpbin.org", "User-Agent": "python-requests/2.18.4", "X-Amzn-Trace-Id": "Root=1-5f704f27-854822ce60e1c5f94da41517" }, "origin": "58.17.121.223", "url": "http://httpbin.org/get?name=germey&age=22" }
通过运行结果我们可以判断，请求的链接自动被构造成了：http://httpbin.org/get?age = 22&name= germey
添加headers
有些网站如果不传递headers则会被禁止访问，所以一般在发起请求之前我们都要进行ＵＡ伪装
POST请求
import requests 2 data = {"name":"germey","age":22} 3 r = requests.post("http://httpbin.org/post",data = data) 4 print(r.text) #运行结果 { "args": {}, "data": "", "files": {}, "form": { "age": "22", "name": "germey" }, "headers": { "Accept": "*/*", "Accept-Encoding": "gzip, deflate", "Content-Length": "18", "Content-Type": "application/x-www-form-urlencoded", "Host": "httpbin.org", "User-Agent": "python-requests/2.18.4", "X-Amzn-Trace-Id": "Root=1-5f70517c-43382ec6284d9ce2a3cd28f1" }, "json": null, "origin": "58.17.121.223", "url": "http://httpbin.org/post" }
其中form就是需要提交的数据
