1、demo1：登录接口

1.1 Flask代码

from flask import request, Flask, jsonify

# 创建1个实例
app = Flask(__name__)

# 解决接收中文报文乱码问题
app.config['JSON_AS_ASCII'] = False


# 登录接口
# 指定路由和请求方法。strict_slashes=False 对URL最后的/符合是否严格要求。False时，路径带不带/都可以。如果是True, 不能加/
@app.route('/api/login', methods=['POST'], strict_slashes=False)
def login():
    # debug信息，打印请求方法
    print(request.method)
    # 获取请求数据，将数据变成字典
    data = request.get_json()
    # 打印请求的数据
    print(data)
    print(type(data))

    # 定义用户名和密码变量，从data中取值
    username = data['username']
    pwd = data['password']

    """
        测试场景（可以根据实际测试情况进行补充）：
        1、参数为空
        2、用户名密码正确
        3、用户密码错误
    """

    if username == "" or pwd == "":
        """
            Flask框架里，可以用jsonify返回json数据
            使用jsonify时，返回的http response的Content-Type是application/json
            这样做是符合HTTP协议规定的，这就是使用jsonify的原因之一
        """
        return jsonify({
            "code": "001",
            "msg": "username or password can not be null"
        })
    elif username == "zz" and pwd == "123456":
        return jsonify({
            "address": {
                "city": "beijing"
            },
            "httpstatus": 200,
            "info": {
                "age": 18,
                "name": "zz"
            },
            "msg": "success",
            "token": "2334nkdnknkadfnkndafkanfdkasnk"
        })
    else:
        return jsonify({
            "code": "001",
            "msg": "username or password is not correct"
        })


if __name__ == '__main__':
    # debug=True 开启调试模式
    # 非debug模式，如果运行的时候代码报错了，网页不会提示详细错误，只会报服务器内部错误
    app.run(debug=True)

1.2 客户端请求

test_case.py

import requests
import pytest

# 账号和密码正确
def test_01():
    data = {
        "username": "cc",
        "password": "123456"
    }

    url = "http://127.0.0.1:5000/api/login"
    resp = requests.post(url=url, json=data)
    print(resp)
    print(resp.text)

# 账号密码都为空
def test_02():
    data = {
        "username": "",
        "password": ""
    }

    url = "http://127.0.0.1:5000/api/login"
    resp = requests.post(url=url, json=data)
    print(resp)
    print(resp.text)

# 账号或密码不正确
def test_03():
    data = {
        "username": "c",
        "password": "123456"
    }

    url = "http://127.0.0.1:5000/api/login"
    resp = requests.post(url=url, json=data)
    print(resp)
    print(resp.text)
    
if __name__ == '__main__':
    pytest.main(['-s', 'test_case.py'])

2、demo2：查询用户信息

2.1 Flask代码

# 查询个人用户信息接口
@app.route('/api/getuserinfo', methods=['GET'], strict_slashes=False)
def api_getUserInfo():
    # 服务端希望token在headers中传过来，不是url
    token = request.headers.get('token')
    if token == "2334nkdnknkadfnkndafkanfdkasnk":
        return jsonify({
            'code': 200,
            'data': [
                {
                    "userid": 122222,
                    "username": "cc",
                    "nickname": "橙子",
                    "openid": "UWENSNNIFIIF3i43344",
                    "userbalance": 5678.02,
                    "userpoints": 43221
                }
            ]
        })
    else:
        return jsonify({
            "code": 1000,
            "msg": "user info is incorrect"
        })

2.2 客户端请求

修改test_01如下

def test_01():
    data = {
        "username": "cc",
        "password": "123456"
    }

    url = "http://127.0.0.1:5000/api/login"
    resp = requests.post(url=url, json=data)
    print(resp)
    print(resp.text)
    token = resp.json()['token']
    # 基于获取的token来实现个人信息的查找
    url = "http://127.0.0.1:5000/api/getuserinfo"
    headers = {
        "token": token
    }
    resp = requests.get(url=url, headers=headers)
    print(resp)
    print(resp.text)
