基于Python Django开发的一个mock

最近研究了一下python的django框架, 发现这个框架不比Java spring boot差, mock同样一个接口, 代码量少很多, 维护起来也很方便, 废话不多说,直接上代码

1. 安装django: pip install django

2. 创建项目: django-admin startproject postdemo

3. 启动项目: python manage.py runserver 0.0.0.0:8001

启动Django项目就这么简单, 三步完成, O(∩_∩)O

postdemo 包下创建views.py

from django.http import HttpResponse

from .utils import process_parameters, validate_parameters, read_response


def postdemo(request):
    if request.method == 'POST':
        dic_params = process_parameters(request.body.decode('utf-8'))   # 一定要用utf-8解码,不然传入的是bytes类型b'body'
        if validate_parameters(dic_params):
            result = read_response()
            res = HttpResponse(result)
            # res.__setitem__("resultcode", '0')  # 用这个也OK, __setitem__可以修改默认的header, 比如Content-Type, setdefault不行
            res.setdefault('resultcode', '0')
            res.setdefault('msg', 'no error')
            return res
        else:
            return HttpResponse('error username or password!')
    else:
        return HttpResponse('error method!')

postdemo 包下创建utils.py, 定义业务逻辑方法, 采用函数式编程也可以

import configparser
import json


def read_config():
    config = configparser.ConfigParser()
    dic = {}
    config.read("./config.ini", encoding="utf8")
    config.sections()
    dic["username"] = config.get("login", "username")
    dic["password"] = config.get("login", "password")
    return dic


def read_response():
    config = configparser.ConfigParser()
    dic = {}
    config.read("./config.ini", encoding="utf8")
    config.sections()
    dic["nickname"] = config.get("response_data", "nickname")
    dic["sex"] = config.get("response_data", "sex")
    dic["age"] = config.get("response_data", "age")
    dic["status"] = config.getint("response_data", "status")
    dic["uid"] = config.get("response_data", "uid")
    return json.dumps(dic, ensure_ascii=False)


def process_parameters(body):
    try:
        body_dic = {}
        key_values = str(body).split("&")
        for key_value in key_values:
            body_dic[key_value.split("=")[0]] = key_value.split("=")[1]
        return body_dic
    except Exception as e:
        return e


def validate_parameters(body):
    if isinstance(body, dict):
        dic_config = read_config()
        if dic_config["username"] == body["username"] and dic_config["password"] == body["password"]:
            return True
        else:
            return False

postdemo包平级目录创建配置文件config.ini

[login]
username=123456789@qq.com
password=123456

[response_data]
nickname=旦增尼玛
sex=1
age=18
status=1
uid=123456789

默认文件urls.py, 添加path

from django.contrib import admin
from django.urls import path

from . import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('postdemo', views.postdemo),
]

默认文件setting.py, 注释掉中间件的csrf安全验证, 其他默认

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
#    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

到这里就完了, 一个简单的post 接口就完成了, 如果还有进行cookie等校验, 完善utils.py业务处理逻辑即可, 启动项目
