Requests接口测试-对cookies的操作处理(一)
大家都对cookie都不陌生,我们本篇文章使用requests结合cookie进行实例演示。我们使用一个接口项目地址,因为接口项目涉及到隐私问题,所以这里接口的地址我暂时不会给大家开放,但是我会给大家演示一个整体cookie的处理流程,因为这部分在实际的接口测试中是十分重点的。大家只需要把处理cookie的流程和原理整明白了,其他的就都好说了。。。我们接下开始干:
首先呢,我们要知道整个cookie的一个实现:
其实cookie是一个客户端的机制,关于cookie的实现其实是很复杂的。大家可以访问这篇文章去学习和了解:深入理解cookie和session ok,我们了解了什么是cookie以后在来看下面的操作。首先我们要知道cookie的一个整个请求处理流程:
1.发送登陆请求
2.登陆成功后
3.获取session信息并返回
4.带着登陆成功后的session登陆后的其他接口
在访问登陆接口时,我们先开启charles进行抓包,然后在定义一个login方法,来看代码的实现方法:
抓取登陆请求后,我们使用requests进行编写login接口:
import requests
def login():
r = requests.post(
'http://xxxxxxx:20080/auth/login',
data={"username":'system',"password":"123456"}
)
return r.json()
print (login())
我们查看登陆后,系统返回的结果:
C:\Python35\python.exe E:/project/index.py
{'code': 200}
Process finished with exit code 0
很明显,返回了一个code=200的状态码,这个并不是我们需要的,我们需要的是登陆后,服务器返回的session,我们要获取这个Session,方便我们访问系统的其他接口,所以,这里面,我们需要使用一个特殊的方法来获取登陆系统后,服务器返回的session,继续往下看,我们将上面的代码进行处理: r.cookies是获取服务器返回的session方法
import requests
def login():
r = requests.post(
'http://xxxxxxx:20080/auth/login',
data={"username":'system',"password":"123456"}
)
return r.cookies
print (login())
返回结果:
<RequestsCookieJar[<Cookie port=20080 for 117.39.63.66/>, <Cookie session=.eJwdjsuKwkAQRX9Fau0ibesmMIuGSJNAdxGoGKo2wmh8lMkmjsRp8d8nzvZwz-W8YH8au_sF8p_x0S1hfz1C_oLFN-SAPqyDbldIO-U2bIQOv-hrw63ceKgT68EK8SYOpYnaGKHGiopyclZ8MyGFp2h_ZS2nD0dqMmznDUkvhQyh_Xhyi-qykESDryde7fqQI7gveS3jcu_G_Hwy8_wA-akbj.DlapFg.6CIk-zQ13C3TbJ-mjjNP_tpxySw for 117.39.63.66/>]>
OK,我们得到了服务端返回的cookies,类似这种的<Cookie session=.eJwdjsuKwkAQRX9Fau0ibesmMIuGSJNAdxGoGKo2wmh8lMkmjsRp8d8nzvZwz-W8YH 然后我们取到session,使用的方法是:r.cookies["session"],看代码如下:
import requests
def login():
r = requests.post(
'http://xxxxxxx:20080/auth/login',
data={"username":'system',"password":"123456"}
)
return r.cookies['session']
print (login())
返回结果如下:
.eJwdjsuKwkAQRX9Fau0ibesmMIuGSJNAdxGoGKo2wmh8lMkmjsRp8d8nzvZwz-W8YH8au_sF8p_x0S1hfz1C_oLFN-SAPqyDbldIO-U2bIQOv-hrw63ceKgT68EK8SYOpYnaGKHGiopyclZ8MyGFp2h_ZS2nD0dqMmznDUkvhQyh_Xhyi-qykESDryde7fqQ2GBx7KOyRV8N828KdE5M1QWpnptKK4XLkCplcs9I7gveS3jcu_G_Hwy8_wA-akbj.Dlaprw.y-qE1LxdvCMnz0W9B87H6Cv8W80
ok,整个cookie的获取流程我们就到这里了。假设如果我们不带上session,直接访问系统的其它任意一个接口,我们来看一下是否可以呢?我们继续定义一个方法,叫getInfo,代码如下:
import requests
def login():
r = requests.post(
'http://xxxxxxx:20080/auth/login',
data={"username":'system',"password":"123456"}
)
return r.cookies['session']
def getInfo():
r =requests.get('http://xxxxx:20080/settings/option/cloud/data')
return r.text
print(getInfo())
查看返回结果:

答案显而易见,我们没有登录成功,所以这个接口我们是无法访问的.这时候我们就要带上session来访问我们刚刚的接口了,我们继续来看 加上session后的整个代码的处理:
import requests
def login():
r = requests.post(
'http://117.39.xxxx/auth/login',
data={"username":'system',"password":"123456"}
)
return r.cookies['session']
def getInfo():
r =requests.get('http://117.39.xxxxx/settings/option/cloud/data',
cookies={"session":login()}) #增加session
return r.json()
print(getInfo())
查看返回的结果:
{'code': 200, 'data': {'cloud_ip': {'value': 'sc.parkingwang.com'}, 'waiting_enable_flag': {'value': '0'}, 'parkno_type': {'value': 0}, 'terminal_operator': {'value': '192.168.199.1'}, 'total_full_limit_type': {'value': '1'}, 'tmp_full_limit_flag': {'value': '0'}, 'cloud_port': {'value': '9001'}, 'arm_no': {'value': '7100000005'}, 'connected': {'value': '1'}, 'pic_upload': {'value': '1'}, 'cloud_url': {'value': 'http://api.com/picupload/'}, 'auth_car_waiting_enable_flag': {'value': '0'}, 'fixed_full_limit_flag': {'value': '0'}}}
很明显,我们登录成功了,系统的接口也访问成功了。
