Python+requests测试接口、关联接口

一个通过筛选，一个提取cookie（有两种写法）

一、依赖接口

（1）第一种方法：requests.session 

准备两个接口：一个登录接口，一个用户查询接口

登录接口：http://cms.duoceshi.cn/manage/loginJump.do

请求体：

userAccount:admin

loginPwd:123456

用户查询接口：http://cms.duoceshi.cn/manage/queryUserList.do

请求体：

startCreateDate:

endCreateDate:

searchValue:

page:1

import   requests
s=requests.Session()
url="http://cms.duoceshi.cn/manage/loginJump.do"
data={'userAccount':'admin','loginPwd':'123456'}
headers={"Content-Type":"application/x-www-form-urlencoded"}
dx=s.request("post",url=url,data=data,headers=headers,)
print(dx.text) #{"code":"200","msg":"登录成功！","model":{}} 响应体
url2="http://cms.duoceshi.cn/manage/queryUserList.do"
data2={'startCreateDate':'','endCreateDate':'','searchValue':'','page':1}
headers2={"Content-Type":"application/x-www-form-urlencoded"}
dx2=s.request("post",url=url2,data=data2,headers=headers2)

print(dx2.text)

（2）通过cookies保持会话

请求头有一个cookie值

将登录接口的cookie值提取（复制）出来，作为下一个接口的请求头

import  requests
class Cms(object):
    def  __init__(self):
        pass
    def  dl(self):
        url="http://cms.duoceshi.cn/manage/loginJump.do"
        data={'userAccount':'admin','loginPwd':'123456'}
        headers={"Content-Type":"application/x-www-form-urlencoded"}
        dx=requests.request("post",url=url,data=data,headers=headers,)
        print(dx.text) #{"code":"200","msg":"登录成功！","model":{}} 响应体
        # print(dx.cookies)
        c=str(dx.cookies) # 将cookie和转换成字符串
        self.s=c.split(" ")[1]
    def yhgl(self):
        url2="http://cms.duoceshi.cn/manage/queryUserList.do"
        data2={'startCreateDate':'','endCreateDate':'','searchValue':'','page':1}
        headers2={"Content-Type":"application/x-www-form-urlencoded","Cookie":self.s}
        dx2=requests.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)
if __name__ == '__main__':
    d=Cms()
    d.dl()
    d.yhgl()

（2）通过提取登录接口的cooike ，作为一个返回值return

（1）

import  requests
class Cms(object):
    def  __init__(self):
        pass
    def  dl(self):
        url="http://cms.duoceshi.cn/manage/loginJump.do"
        data={'userAccount':'admin','loginPwd':'123456'}
        headers={"Content-Type":"application/x-www-form-urlencoded"}
        dx=requests.request("post",url=url,data=data,headers=headers,)
        print(dx.text) #{"code":"200","msg":"登录成功！","model":{}} 响应体
        # print(dx.cookies)
        c=str(dx.cookies) # 将cookie和转换成字符串
        s=c.split(" ")[1]
        return s
    def yhgl(self):
        f=self.dl()
        url2="http://cms.duoceshi.cn/manage/queryUserList.do"
        data2={'startCreateDate':'','endCreateDate':'','searchValue':'','page':1}
        headers2={"Content-Type":"application/x-www-form-urlencoded","Cookie":f}
        dx2=requests.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)
if __name__ == '__main__':
    d=Cms()
    d.dl()
    d.yhgl()

关联接口：省份接口，关连接口

上一个接口的响应体，作为下一个接口的请求体

案例：

准备省份接口

城市接口：

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportProvince

城市接口：

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity

入参：

byProvinceName:城市名称

案例1：管理接口单独调通

import  requests
s=requests.Session()
class Gl(object):
    def __init__(self):
        pass
    def  sf(self):
        url="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportProvince"
        headers = {"Content-Type": "application/x-www-form-urlencoded"}
        dx=s.request("get",url=url,headers=headers)
        print(dx.text)
    def  cs(self):
        url2="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity"
        data2={"byProvinceName":"浙江"}
        headers2 = {"Content-Type": "application/x-www-form-urlencoded"}
        dx2=s.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)

if __name__ == '__main__':
    d=Gl()
    d.sf()
    d.cs()

管理接口：

将省份的响应体提取出来，用到re正则提取，

在存放在城市的请求体中

提取汉字：

<string>（.+?）</string>   内容匹配0次或1次或n次，

. 匹配任意字符   +  匹配1次或n次   ？是匹配0次或1次

（1）管理接口中 通过self.实例变量

import re
import  requests
s=requests.Session()
class Gl(object):
    def __init__(self):
        pass
    def  sf(self):
        url="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportProvince"
        headers = {"Content-Type": "application/x-www-form-urlencoded"}
        dx=s.request("get",url=url,headers=headers)
        nr=dx.text
        self.tq=re.findall("<string>(.+?)</string>",nr)[3]
        print(self.tq)
    def  cs(self):
        url2="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity"
        data2={"byProvinceName":self.tq}
        headers2 = {"Content-Type": "application/x-www-form-urlencoded"}
        dx2=s.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)

if __name__ == '__main__':
    d=Gl()
    d.sf()
    d.cs()

（2）通过return 来进行传递

import  requests
import  re
s=requests.Session()
class Gl(object):
    def __init__(self):
        pass
    def  sf(self):
        url="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportProvince"
        headers = {"Content-Type": "application/x-www-form-urlencoded"}
        dx=s.request("get",url=url,headers=headers)
        nr=dx.text
        tq=re.findall("<string>(.+?)</string>",nr)[3]
        return tq
    def  cs(self):
        c=self.sf()
        url2="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity"
        data2={"byProvinceName":c}
        headers2 = {"Content-Type": "application/x-www-form-urlencoded"}
        dx2=s.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)

if __name__ == '__main__':
    d=Gl()
    d.sf()

d.cs()

重点是提取：所有的省份    tq=re.findall("<string>(.+?)</string>",nr)

（3）随机获取省份

import  requests
import  re
import  random
s=requests.Session()
class Gl(object):
    def __init__(self):
        pass
    def  sf(self):
        url="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportProvince"
        headers = {"Content-Type": "application/x-www-form-urlencoded"}
        dx=s.request("get",url=url,headers=headers)
        nr=dx.text
        tq=re.findall("<string>(.+?)</string>",nr)
        self.b=random.choice(tq)  #调用随机模块

    def  cs(self):
        c=self.sf()
        url2="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity"
        data2={"byProvinceName":self.b}
        headers2 = {"Content-Type": "application/x-www-form-urlencoded"}
        dx2=s.request("post",url=url2,data=data2,headers=headers2)
        print(dx2.text)

if __name__ == '__main__':
    d=Gl()
    d.sf()
    d.cs()
