Python接口自动化测试之Requests库&Pytest框架

  1. 发送get请求

#导包
import requests
#定义一个url
url = "http://xxxxxxx"
#传递参数
payload="{\"head\":{\"accessToken\":\"\",\"lastnotice\":0,\"msgid\":\"\"},\"body\":{\"user_name\":\"super_admin\",\"password\":\"b50c34503a97e7d0d44c38f72d2e91ad\",\"role_type\":1}}"
headers = {
  'Content-Type': 'text/plain',
  'Cookie': 'akpsysessionid=bafc0ad457d5a99f3a4e53a1d4b32519'
}
#发送get请求
r = requests.get( url=url,headers=headers, data=payload)
#打印结果
print(r.text)
#解码
print(r.encoding)
print(r.text.encode('utf-8').decode('unicode_escape'))#先把返回的结果转换成utf-8，再去解码成中文的编码

  1. 发送post请求

#导包
import requests
#定义一个url
url = "http://xxxxxxx"
#传递参数
payload="{\"head\":{\"accessToken\":\"\",\"lastnotice\":0,\"msgid\":\"\"},\"body\":{\"user_name\":\"super_admin\",\"password\":\"b50c34503a97e7d0d44c38f72d2e91ad\",\"role_type\":1}}"
headers = {
 'Content-Type': 'text/plain',
 'Cookie': 'akpsysessionid=bafc0ad457d5a99f3a4e53a1d4b32519'
}
#发送post请求
r = requests.post( url=url,headers=headers, data=payload)
#打印结果
print(r.text)

  1. 发送https请求

import requests
url='https://www.ctrip.com/'
#第一种解决方案，发送请求的时候忽略证书，证书的参数verify用的比较多
r=requests.post(url=url,verify=False)#verify参数默认为True，值为False，表示忽略证书
#第二张解决方案，verify里面添加证书的路径
r=requests.post(url=url,verify='证书的路径')#verify参数默认为True，值为False，表示忽略证书
print(r.text)

  1. 文件上传

import requests
file = {
    'filename':open('文件名称','rb')
}
response = requests.post("网址",file)
print(response.text)

  1. 文件下载

#小文件下载
import requests
r = requests.get("https://img.sitven.cn/Tencent_blog_detail.jpg")
with open(r"D:\a.jpg", "wb") as f:
    f.write(r.content)
 
#大文件下载
import requests
def test_downloads(url, file):
    s = requests.session()
    r = s.get(url, stream=True, verify=False)
    with open(file, "wb") as f:
        for chunk in r.iter_content(chunk_size=512):
            f.write(chunk) 
if __name__ == "__main__":
    url = "https://www.url.com/test/export"
    file = "D:\\a.xlsx"
    test_downloads(url=url, file=file)
#转载至：https://blog.csdn.net/weixin_43507959/article/details/107326912

  1. timeout超时

#导包
import requests
#循环10次
for i in range(0,10):
    try:
        url="http://xxxxxxxxxxxxxxxx"
        data={
            "head":{"lastnotice":0,"msgid":"","accessToken":"89a08bff-15d7-4d7a-9967-0b5f4fb699ce"},
            "body":{"clinicid":"978f661e-1782-43bd-8675-b0ff1138ab7c","deptid":"09b8515b-b01b-4771-9356-aed6b5aa01bf","doctorid":"65ac0251-10ff-473a-af8a-20e8969176f7","registtype":0,"card_num":"","bcc334":"","patientopt":1,"bkc368":"1","patient":{"cardid":"","medicalcardid":"","label":"","sourcetype":1,"nationid":"01","maritalstatus":0,"address":"","company":"","jobname":"","email":"","remark":"","bcc334":"","name":"11","gender":1,"phone":"","birthdate":"2020-03-23","patienttype":1,"szsbcardid":""}}
        }
#发送post请求，超时时间0.03s
        r=requests.post(url=url,json=data,timeout=0.03)
        print(r.text)
        print(r.cookies)
    except:
        print('error')
#可参考：https://blog.csdn.net/weixin_44350337/article/details/99655387

  1. 鉴权

7.1 auth参数鉴权

import requests
url = 'http://192.168.1.1'
headers = {} # 有的不带头也能请求到 不带头可以忽略这行 和headers=headers,这两处
r = requests.get(url, auth=('admin', '123456'), headers=headers, timeout=10)
print(r.text)

7.2 session操作

#实例化session
session = requests.session()
#使用session发起请求
response = session.post(url,headers=req_header,data=form_data)

7.3 token操作

import requests
url="http://xxxxxxxxxxxxxxx"
 
json={
    "head":{"accessToken":"","lastnotice":0,"msgid":""},
    "body":{"username":"15623720880","password":"48028d2558577c526a017883211b4066","forceLogin":0}
}
r=requests.post(url=url,json=json)
print(r.text)
print(r.cookies)
 
#登录成功后返回token，带入下一个接口
for i in range(0,1):
    try:
        url="xxxxxxxxxxxxxxxxxx"
        data={
            "head":{"lastnotice":0,"msgid":"","accessToken":"89a08bff-15d7-4d7a-9967-0b5f4fb699ce"},
            "body":{"clinicid":"978f661e-1782-43bd-8675-b0ff1138ab7c","deptid":"09b8515b-b01b-4771-9356-aed6b5aa01bf","doctorid":"65ac0251-10ff-473a-af8a-20e8969176f7","registtype":0,"card_num":"","bcc334":"","patientopt":1,"bkc368":"1","patient":{"cardid":"","medicalcardid":"","label":"","sourcetype":1,"nationid":"01","maritalstatus":0,"address":"","company":"","jobname":"","email":"","remark":"","bcc334":"","name":"11","gender":1,"phone":"","birthdate":"2020-03-23","patienttype":1,"szsbcardid":""}}
        }
        r=requests.post(url=url,json=data,timeout=0.09)
        print(r.text)
        print(r.cookies)
    except:
        print('error')

7.4 sign签名

# appid：wxd930ea5d5a258f4f
# mch_id：10000100
# device_info：1000
# body：test
# nonce_str：ibuaiVcKdpRxkhJA
import hashlib
#需要加密的字符串
stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_id=10000100&nonce_str=ibuaiVcKdpRxkhJA";
#构建一个对象为md
md=hashlib.md5()
#对stringA字符串进行编码
md.update(stringA.encode()) 
#生成后的加密值
AES=md.hexdigest()
#把加密的结果，小写转大写 upper函数
AES=AES.upper()
print(AES)

common 公共的方法（python package）
testdata 测试数据（python package）
test_case测试用例（python package）
report 报告（directory）
run_case 测试执行（python package）
log 日志

8.1 config配置文件

def server_ip():
    '''
    ait_ip=''开发环境的服务器ip
    sit_ip=''测试环境的服务器ip
    :return: 返回不同服务器的地址
    '''
 
 
    server_add={
        'dev_ip' : 'http://his.xxxxxxxxxxx.com',
        'sit_ip' : 'http://his.xxxxxxxxxxxx.comm'

 8.2 common 公共的方法

# 封装一个读取Excel表格数据的函数
# 对Excel表格数据的读取需要用到一个库——xlrd库

    读取表中一行的数据
    :return:返回2，3行数据
    '''

    # sheet = book.sheet_by_name("Sheet1") 根据工作表的名字，获取一个工作表对象
    sheet = book.sheet_by_index(0)  # 获取一个工作表，以index的方式，这里是获取第1个工作表
    return sheet.cell_value(i,1),sheet.cell_value(i,2)

8.3 testdata 测试数据

主要存放xls，txt，csv测试数据

Python接口自动化测试之Requests库&Pytest框架-LMLPHP

8.4 test_case测试用例

 8.5 report 报告

主要存放html，xml报告

Python接口自动化测试之Requests库&Pytest框架-LMLPHP

8.6 run_case 测试执行

import pytest
 
'''
测试文件以test_开头，（以—_test结尾也可以）
测试类以Test开头，并且不能带有init 方法
测试函数以test_开头
断言使用基本的assert即可
'''
#如何去运行测试用例，_test开头的函数就可以，判断用例运行是否成功，assert断言
if __name__=="__main__":
    #单个文件运行，运行添加，对应的文件路径，路径要用相对路径
    # pytest.main(['../test_case//test_case_01.py'])
    #多个文件运行，运行添加多个对应的文件路径，列表的形式，去添加多个文件的路径
    # pytest.main(['../test_case/test_fore.py','../test_case/Dynamic correlation_token.py'])
    #运行整个目录，添加目录的路径
    pytest.main(['../test_case/','--html=../report/report.html','--junitxml=../report/report.xml'])
 
'''
pytest生成报告：
1、生成html报告
'--html=../report/report.html'
2、生成xml报告
'--junitxml=../report/report.xml'
'''
