接口自动化测试（一）Requests模块基本操作

 字符串解码和查看请求信息

# lebo='天津杰森'
# print(lebo)
# 字符串编码
# lebo_text=lebo.encode()
#print(lebo_text)
# 字符串解码
# print(lebo_text.decode())

import requests

url='http://www.baidu.com'
# 发起get请求
response=requests.get(url)
# 查看状态码
# print(response.status_code)
# 响应头
# print(response.headers)
# 请求头
print(response.request.headers)

# 指定utf-8格式，进行解码
# response.encoding='utf-8'
# print(response.text)

# 默认使用utf-8进行解码
# print(response.content.decode())

发送get请求

import requests

# url='https://www.baidu.com'
url='https://www.zhihu.com'

#构建请求头
headers={
	'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36'
}

response=requests.get(url,headers=headers)
#打印response对应的request请求头
print(response.request.headers)
#打印响应状态吗
print(response.status_code)
# print(response.content.decode())

pip list打开编辑器所有已安装的包

​​import requests

url='https://www.baidu.com/s'

#构建请求头
headers={

	'wd':'python'
}
response=requests.get(url,headers=headers,params=params)

with open('test.html','w',encoding='utf-8') as f:
	f.write(response.content.decode())

发送请求

import requests

class login(object):
	def __init__(self):
		self.url=' http://106.13.46.164:8080/iwebshop/index.php?controller=simple&action=login_act'
		self.data={
			'login_info': 'zhang',
			'password': '111111'
				   }
		self.headers={
	'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36'
}

	def post_method(self):
		response=requests.post(url=self.url,headers=self.headers,data=self.data)
		return response.content
if __name__=='__main__':
	login=login()
	res=login.post_method()

	with open('test.html', 'w', encoding='utf-8') as f:
		f.write(res.decode())
	# 断言是否登录成功
	assert 'zhang' in res.decode()

jason接口

import requests
import json

url='http://106.13.46.164:8080/iwebshop/index.php?controller=simple&action=joinCart&goods_id=147&random=0.771087505969752&type=goods'

#构建请求头

}
response=requests.get(url,headers=headers)
print(response.content.decode('unicode-escape'))
# jason 格式转换为字典
dict_data=json.loads(response.content)

print(dict_data)
# 断言 false 小写传过来变为大写
assert dict_data['isError'] is False

# with open('test.html','w',encoding='utf-8') as f:
# 	f.write(response.content.decode())

设置代理
