Python request操作步骤及代码实例
操作步骤
A.cmd输入:pipinstallrequests,安装requests
B.py文件导入:importrequests
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 importunittest importrequests importjson classlogin(unittest.TestCase): defsetUp(self): self.d='http://127.0.0.1:9999' self.json_headers={'content-type':'application/json'} deftearDown(self): pass deftest_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) deftest_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') deftest_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') defurl(self,path): returnself.d+path if__name__=='__main__': unittest.main()
