python－－requests模块详解

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
