六、python request运用

操作步骤

• A.cmd输入：pip install requests，安装requests
• B.py文件导入：import requests
• C.get
  调用get： r = requests.get(url)
  断言：self.assertEqual(r.status_code, 200)
  说明：status_code为状态返回值，如200表示访问成功
• D.post

1. 入参为json格式需要把字典转成json格式： json_data =json.dumps({"usename": "test","password" : "123456"}) ，
2. 请求报头为json格式：self.json_headers=
3. 调用post（请求与返回都是josn格式）：
   r = requests.post(url,data=json_data,headers=self.json_headers)
4. 如果返回内容为：[{'name': 'zhangshan', 'age': '18'}, {'name': 'lisi', 'age': '29'}]
   断言1：self.assertEqual(r.json()[0]['name'], 'zhangshan') ，说明r.json()转成list，list里面是字典，取list[0]第一个值，取字典key值['name']
5. 如果返回内容：{'success': 'true', 'msg': 'chengong'}
   断言2：self.assertEqual(r.json()['success'], 'true')，说明r.json()转成字典，取字典key值['success']

config.json 配置文件内容：

[
  {
    "request" :
      {
        "method": "post",
        "uri" : "/login",
        "file": {
          "json": "user.json"
        }
      },
    "response" :
    {
      "json": {"success": "true","msg": "chengong"}
    }
  },
  {
    "request" :
      {
        "method": "post",
        "uri" : "/data"
      },
    "response" :
    {
      "file" : "data.json"
    }
  },
  {
    "request" :
      {
        "method": "get",
        "uri" : "/home"
      },
    "response" :
    {
        "text" : {
          "template": "true"
        }
    }
  }
]

data.json 返回值文件内容：

[
  {
    "name": "zhangshan",
    "age": "18"
  },
  {
    "name": "lisi",
    "age": "29"
  }
]

user.json 入参文件内容：

{
	"usename": "test",
	"password" : "123456"
}

python文件“login.py”内容：

#!/usr/bin/python3
# encoding:utf-8
import unittest
import requests
import json

class login(unittest.TestCase):
    def setUp(self):
        self.d ='http://127.0.0.1:9999'
        self.json_headers= {'content-type': 'application/json'}
        
    def tearDown(self):
        pass
    def test_gethome(self):
        url = self.url('/home')#http://127.0.0.1:9999/home
        r = requests.get(url)
        self.assertEqual(r.text, 'true')
        self.assertEqual(r.status_code, 200)
        
    def test_postlogin(self):
        url= self.url('/login')
        json_data =json.dumps({"usename": "test","password" : "123456"}) 
        r = requests.post(url,data=json_data,headers=self.json_headers)
        #{'success': 'true', 'msg': 'chengong'}
        self.assertEqual(r.json()['success'], 'true')
        
    def test_postdata(self):
        url= self.url('/data')
        r = requests.post(url,data={},headers=self.json_headers)
        print(len(r.json()))#r.josn返回list，长度2
        #[{'name': 'zhangshan', 'age': '18'}, {'name': 'lisi', 'age': '29'}]
        self.assertEqual(r.json()[0]['name'], 'zhangshan')
        self.assertEqual(r.json()[-1]['age'],'29')
  
        
    def url(self,path):
        return self.d + path
if __name__=='__main__':
    unittest.main()
