python中requests模块使用

import requests

1.发送get请求
url = 'http:///api/user/stu_info'

req = requests.get(url,params=data) #发送get请求
print(req.json()) #字典 单引号'
print(req.text) #string 双引号"

2.发送post请求
url = 'http:///api/user/login'
data = {
    'username':'niuhanyang',
    'passwd':'aA123456'
} #请求数据
req = requests.post(url,data)#发送post请求
print(req.json())

3.入参是json类型
import random
phone = random.randint(10000000000,99999999999)
url = 'http:///api/user/add_stu'
data =  {
    "name":"yyy",
    "grade":"天蝎座",
    "phone":phone,
    "sex":"男",
    "age":28,
    "addr":"河南省济源市北海大道32号"
  }
req = requests.post(url,json=data)
print(req.json())

4.添加cookie
url = 'http:///api/user/gold_add'
data = {'stu_id':468,'gold':100000}
cookie = {'niuhanyang':'337ca4cc825302b3a8791ac7f9dc4bc6'}
req = requests.post(url,data,cookies=cookie)
print(req.json())


5.添加header
url = 'http:///api/user/all_stu'
header = {
    'Referer':'http://api.nnzhp.cn/'
}
req = requests.get(url,headers = header)
print(req.json())

6.上传文件
url = 'http:///api/file/file_upload'

  #  'file':open('baidu.html',encoding='utf-8')  #图片与excel是rb
    'file':open('E:神州-BDCSC测试相关文档getSumByViewId.csv','rb')
}
req = requests.post(url,files = data,)
print(req.json())

url = 'url = 'http:///wp-content/uploads/2018/01/soup.jpg''
req = requests.get(url)
print(req.content) #返回的二进制
fw = open('m.mp3','wb')#二进制写模式wb
