requests接口自动化测试

一、什么是requests？

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、下载

pip install requests

三、请求方式

1.get请求

# GET无参请求
r = requests.get('http://www.baidu.com')

# GET有参请求

1.方法一
canshu = {"consName": "水瓶座","key":26183f3f48d787b5541aa3d0e767b359}
r = requests.get("http://web.juhe.cn:8080/constellation/getAll", params=canshu)
print(r)

2.方法二
r = requests.get("http://web.juhe.cn:8080/constellation/getAll?consName=水瓶座&key=26183f3f48d787b5541aa3d0e767b359")
print(r.text)

2.post请求

canshu = {"consName": "水瓶座", "key": "26183f3f48d787b5541aa3d0e767b359"}
r = requests.post("http://web.juhe.cn:8080/constellation/getAll", data=canshu)
print(r.text)

3.响应的内容

r.encoding                       # 获取当前的编码
r.encoding = 'utf-8'             # 设置编码
r.text                           # 以encoding解析返回内容。字符串方式的响应体，会自动根据响应头部的字符编码进行解码。
r.content                        # 以字节形式（二进制）返回。字节方式的响应体，会自动为你解码 gzip 和 deflate 压缩。

r.headers                        # 以字典对象存储服务器响应头，但是这个字典比较特殊，字典键不区分大小写，若键不存在则返回None

r.status_code                     # 响应状态码
r.raw                             # 返回原始响应体，也就是 urllib 的 response 对象，使用 r.raw.read()   
r.ok                              # 查看r.ok的布尔值便可以知道是否登陆成功
 #*特殊方法*#
r.json()                         # Requests中内置的JSON解码器，以json形式返回,前提返回的内容确保是json格式的，不然解析出错会抛异常
r.raise_for_status()             # 失败请求(非200响应)抛出异常

4.超时设置

requests.get(url,timeout=1) # 超过等待时间则报错

5.添加请求头信息

requests.get(url,headers=headers) # 设置请求头

6.添加文件

requests.post(url, files=files) # 添加文件 

7.文件传输

url = 'http://httpbin.org/post' 
files = {'file': open('report.xls', 'rb')} 
r = requests.post(url, files=files)

四、requests+pytest+allure

1.读取csv文件
