learning-API-test

帮助你学习API接口测试。

开始

安装

克隆或下载项目，安装依赖。

$ pip install -r requirements.txt

启动接口服务

$ python api_server.py

* Serving Flask app "api_server.py" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 208-740-173

Flask Web框架可以非常简单的方式实现API，项目中的所有API都在api_server.py 文件中。

接口测试库

所有例子使用Requests 库调用，你也可以使用其他API测试工具，如Postman、JMeter等。

http接口的基本信息

URL (http://www.xxx.com/v1/login)
方法：GET/POST/PUT/DELETE
Auth
Header
参数类型（form-data/json..）
参数值（id=1，name=tom）
参数加密方式
返回值（错误码/提示信息/数据）

接口测试例子

最简单的接口调用

import requests

r = requests.get("http://127.0.0.1:5000/")
result = r.json()
print(result)

返回结果：

{"code": 10200, "message": "Welcome to API testing"}

RESTful 风格的API

import requests

name = "tom"
r = requests.get("http://127.0.0.1:5000/user/"+name)
result = r.json()
print(result)

返回结果：

{"code": 10200, "message": "hello, tom"}

根据用户id返回不同的结果

import requests

uid = "1"
r = requests.get("http://127.0.0.1:5000/id/"+uid)
result = r.json()
print(result)

返回结果：

{"code": 10101, "message": "user id null"}
{"code": 10200, "data": {"age": 22, "id": 1, "name": "tom"}, "message": "success"}

一般GET请求

方法一

import requests

payload = {'q': 'selenium'}
r = requests.get("http://127.0.0.1:5000/search/", params=payload)
result = r.json()
print(result)

方式二

import requests

r = requests.get("http://127.0.0.1:5000/search/?q=selenium")
result = r.json()
print(result)

返回结果：

{"code": 10200, "data": ["selenium教程", "seleniumhq.org", "selenium环境安装"], "message": "success"}

POST请求

参数类型为：from-data/x-www-from-urlencode格式

import requests

payload = {'username': 'admin', "password": "a123456"}
r = requests.post("http://127.0.0.1:5000/login", data=payload)
result = r.json()
print(result)

返回结果：

{"code": 10102, "message": "username or passwrord is None"}
{"code": 10203, "message": "username or passwrord is null"}
{"code": 10104, "message": "username or password error"}
{"code": 10200, "message": "login success"}

POST请求

参数类型为：JSON格式

import requests

payload = {'name': 'jack', "age": 22, "height": 177}
r = requests.post("http://127.0.0.1:5000/add_user", json=payload)
result = r.json()
print(result)

返回结果：

{"code": 10102, "message": "key null"}
{"code": 10103, "message": "name null"}
{"code": 10104, "message": "name exist"}
{"code": 10105, "message": "format error"}
{"code": 10200, "message": "add success",  
 "data": {
   "age": 22, "height": 177, "name": "jack"
   },
}

带Header的接口

import requests

headers = {"Content-Type": "application/json",
            "token": "3d80caXELzU1aWmHwxl0TzW7jtterObm8l5EeAfipnhyaKmhFl8KdhFRvy4"}
r = requests.post("http://127.0.0.1:5000/header", headers=headers)
result = r.json()
print(result)

返回结果：

{
  "code": 10200, "message": "header ok!", 
  "data": {
    "Content-Type": "application/json",
    "token": "3d80caXELzU1aWmHwxl0TzW7jtterObm8l5EeAfipnhyaKmhFl8KdhFRvy4"
   },
}

带Basic Auth认证的接口

import requests

auth = ("admin", "admin123")
r = requests.post("http://127.0.0.1:5000/auth", auth=auth)
result = r.json()
print(result)

返回结果：

{"code": 10101, "message": "Authorization None"}
{"code": 10102, "message": "Authorization null"}
{"code": 10103, "message": "Authorization fail!"}
{"code": 10200, "message": "Authorization success!"}

上传文件的接口

import requests

files = {'file': open('D:\\log.txt', 'rb')}
r = requests.post("http://127.0.0.1:5000/upload", files=files)
result = r.json()
print(result)

返回结果：

{"code": 10200, "message": "upload success!"}

同一个URL，根据方法实现不同功能

GET请求，一般用作获取数据接口。

import requests

r = requests.get("http://127.0.0.1:5000/phone/1")
result = r.json()
print(result)

返回结果：

{"code": 10101, "message": "The phone id is empty"}
{"code": 10201, "message": "get success", 
 "data": {
   "id": 1, "name": "小米手机", "price": 1999
  }
}

PUT请求，一般用作更新数据接口。

import requests

data = {"name":"华为手机", "price": "3999"}
r = requests.put("http://127.0.0.1:5000/phone/1", data=data)
result = r.json()
print(result)

返回结果：

{"code": 10102, "message": "The updated phone id is empty"}
{"code": 10202, "message": "update success",
 "data": {
   "id": 1, "name": "华为手机", "price": "3999"
  }
}

DELETE请求, 一般用作删除数据接口。

import requests

r = requests.delete("http://127.0.0.1:5000/phone/1")
result = r.json()
print(result)

返回结果：

{"code": 10103, "message": "The deleted phone id is empty"}
{"code": 10203, "message": "delete success"}

通过Session记录登录状态

import requests

s = requests.Session()
r = s.post("http://127.0.0.1:5000/user_login", data={"username": "jack", "password": "123"})
result = r.json()
print(result)

r2 = s.get("http://127.0.0.1:5000/user_data")
result2 = r2.json()
print(result2)

返回结果：

{"code": 10200, "message": "login success"}
{"code": 10200, "message": "hello, jack"}
