一、介绍
requests是一个很实用的python http客户端库,编写爬虫和测试服务器响应数据时经常会用到,requests是python语言的第三方的库,专门用于发送http请求
二、前提
1
|
pip install requests |
三、get的请求
3.1 get无参请求
1
|
r = requests.get( 'http://www.baidu.com' ) |
3.2 get传参
1
2
|
payload = { 'key1' : 'value1' , 'key2' : 'value2' , 'key3' : none} r = requests.get( 'http://www.baidu.com ' , params = payload) |
案例:测试聚合数据

import requests class userequestclass(): #get传参的第一种方式 def xwttmethod( self ): r = requests.get( "http://v.juhe.cn/toutiao/index?type=guonei&key=4b72107de3a197b3bafd9adacf685790" ) print (r.text) #get传参的第二种方式 def xwttmethod( self ): params = { "type" : "guonei" , "key" : "4b72107de3a197b3bafd9adacf685790" } r = requests.get( "http://v.juhe.cn/toutiao/index" ,params = params) print (r.text) |
四、post请求
类似python中的表单提交
1
2
|
payload = { 'key1' : 'value1' , 'key2' : 'value2' } r = requests.post( "http://httpbin.org/post" , data = payload) |

import requests class userequestclass(): def xwttpostmethod( self ): params = { "type" : "guonei" , "key" : "4b72107de3a197b3bafd9adacf685790" } r = requests.post( "http://v.juhe.cn/toutiao/index" ,params = params) #print(r.status_code) return r.status_code |
五、requests响应
1
2
3
4
5
6
|
r.status_code 响应状态码 r.heards 响应头 r.cookies 响应cookies r.text 响应文本 r. encoding 当前编码 r. content 以字节形式(二进制)返回 |
最常用的是根据响应状态码判断接口是否连通,经常用于做接口中断言判断
六、request扩充

1. 添加等待时间 requests.get(url,timeout = 1 ) #超过等待时间则报错 2. 添加请求头信息 requests.get(url,headers = headers) #设置请求头 3. 添加文件 requests.post(url, files = files) #添加文件 |
文件传输

|
url = 'http://httpbin.org/post' files = { 'file' : open ( 'report.xls' , 'rb' )} r = requests.post(url, files = files) |
七、requests+pytest+allure
7.1 流程如下
读取文件中的数据
requests拿到数据请求接口返回状态码
通过断言验证返回状态码和200对比
生成allure的测试报告
7.2 模块总览

通过excel另存为csv即可。
7.3.2 读取数据(readdemo)
