Python request操作步骤及代码实例
作者:天天向上327 时间:2022-03-16 10:42:47
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
入参为json格式需要把字典转成json格式: json_data =json.dumps({"usename": "test","password" : "123456"}) ,
请求报头为json格式:self.json_headers= {'content-type': 'application/json'}
调用post(请求与返回都是josn格式):
r = requests.post(url,data=json_data,headers=self.json_headers)
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']
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()
运行结果
