Requests 是用Python语言编写，基于 urllib，采用 Apache2 Licensed 开源协议的 HTTP 库。

它比 urllib 更加方便，可以节约我们大量的工作，完全满足 HTTP 测试需求。

# 1.GET请求 #

## 不带参数 ##

import requests
    
    print('==== get1 ====')
    req = requests.get(url='https://movie.douban.com/chart')
    print(req.status_code)

## 带参数 ##

import requests
    
    print('==== get2 ====')
    req = requests.get(url='https://www.baidu.com/s', params={
       'wd': 'python'})
    print(req.url)
    print(req.text)

# 2.POST请求 #

import requests
    import json
    
    print('==== post ====')
    req = requests.post('https://api.github.com/some/endpoint', data=json.dumps({
       'some': 'data'}))
    print(req.json())

# 3.设置header头 #

import requests
    
    print('==== header ====')
    data = {
       'some': 'data'}
    headers = {
       'Content-Type': 'application/json;charset=UTF-8',
               'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'}
    
    req = requests.post('https://api.github.com/some/endpoint', data=data, headers=headers)
    print(req.text)

# 4.上传文件 #

import requests
    
    print('==== upload ====')
    url = 'http://www.test.com/upload'
    files = {
       'file': open('data/blur.jpg', 'rb')}
    
    req = requests.post(url, files=files)
    print(req.text)

# 5.设置Cookies #

import requests
    import json
    
    print('==== cookies ====')
    url = 'http://github.com'
    cookies = {
       'name_cookie': 'xiao', 'age_cookie': '25'}
    # 特殊符号都不能作为Cookie的内容
    req = requests.get(url, cookies=cookies)
    
    print(req.json())
    print(req.cookies['name_cookie'])

# 6.设置请求超时 #

import requests
    
    req = requests.get('http://github.com', timeout=0.001)
    print(req.status_code)
