lsshu-cms 2.0.5

FastAPI 开发的CMS

Lsshu

[e-mail]

安装

pip install lsshu-cms

使用

1、在项目根目录新建文件 main.py

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware
from lsshu.oauth.main import router as router_oauth

app = FastAPI(
    title='Base API Docs',
    description='Base API接口文档',
    version='1.0.0'
)
app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)
app.include_router(router_oauth, prefix="/api")
if __name__ == '__main__':
    import uvicorn

    uvicorn.run("main:app", host="0.0.0.0", port=8000, reload=True)

2、在项目根目录新建python包 app 在包app下打开文件 __init__.py

if __name__ == '__main__':
    from lsshu.oauth.model import Model, Engine

    Model.metadata.create_all(Engine)  # 创建表结构

    APP_PERMISSIONS = []

    from config import OAUTH_ADMIN_USERS
    from lsshu.internal.helpers import store_permissions, init_user_and_password

    store_permissions(APP_PERMISSIONS)  # 初始化权限
    init_user_and_password(OAUTH_ADMIN_USERS)  # 初始化授权用户

3、在包app下新建python包 demo 在包demp下新建文件 model.py

from sqlalchemy import Column, String

from lsshu.internal.db import Model
from lsshu.internal.method import plural

name = plural(__name__.capitalize())
table_name = name.replace('.', '_')
permission = {"name": "Demo", "scope": name, "action": [{"name": "de", "scope": "de"}]}


class Models(Model):
    """ 模型 """
    __tablename__ = table_name
    name = Column(String(15), nullable=False, unique=True, comment="名称")

4、在包demo下新建文件 crud.py

from lsshu.demo.model import Models
from lsshu.internal.crud import BaseCRUD


class CRUD(BaseCRUD):
    """表操作"""
    params_model = Models

5、在包demo下新建文件 schema.py

from datetime import datetime
from typing import Optional, List

from pydantic import BaseModel

from lsshu.internal.schema import SchemasPaginate


class SchemasResponse(BaseModel):
    """模型 返回"""
    id: int
    name: Optional[str] = None
    created_at: Optional[datetime] = None
    updated_at: Optional[datetime] = None

    class Config:
        orm_mode = True


class SchemasStoreUpdate(BaseModel):
    """模型 提交"""
    name: Optional[str] = None


class SchemasPaginateItem(SchemasPaginate):
    items: List[SchemasResponse]


class SchemasParams(BaseModel):
    pass

6、在包demo下新建文件 main.py

7、在根目录下新建文件 config.py

import os

ROOT_PATH = os.path.dirname(__file__)
# API 接口返回数据
SCHEMAS_SUCCESS_CODE: int = 0
SCHEMAS_SUCCESS_STATUS: str = 'success'
SCHEMAS_SUCCESS_MESSAGE: str = '数据请求成功！'
SCHEMAS_ERROR_CODE: int = 1
SCHEMAS_ERROR_STATUS: str = 'error'
SCHEMAS_ERROR_MESSAGE: str = '数据请求失败！'

# 站点
HOST_URL: str = ""

# 上传目录
UPLOAD_NAME: str = "static"
UPLOAD_DIR: str = "static"
UPLOAD_URI: str = "/static"

# OAuth 授权相关
OAUTH_DEFAULT_TAGS: list = ['OAuth']
OAUTH_LOGIN_SCOPES: str = "login"

OAUTH_TOKEN_URI: str = "/token"
OAUTH_TOKEN_URL: str = "/api%s" % OAUTH_TOKEN_URI
OAUTH_SCOPES_URI: str = "/scopes"
OAUTH_TOKEN_SCOPES: dict = {
    OAUTH_LOGIN_SCOPES: OAUTH_LOGIN_SCOPES.capitalize()
}
OAUTH_SECRET_KEY: str = "4a876f7766d1a0e9d97231089be927e38d6dea09233ad212f056b7f1a75cd41d"
OAUTH_ALGORITHM: str = "HS256"
OAUTH_ACCESS_TOKEN_EXPIRE_MINUTES: int = 300
OAUTH_OAUTH_ROUTER: dict = {}

# 超级管理员 账号:密码
OAUTH_ADMIN_USERS: dict = {
    "admin": "admin"
}

# 数据库相关
DB_SQLALCHEMY_DATABASE_URL: str = "sqlite:///{}".format(os.path.join(ROOT_PATH, 'db.sqlite3'))
# DB_SQLALCHEMY_DATABASE_URL = "mysql+pymysql://root:root@192.168.1.3:3306/ic" # ic 数据库

# echo=True表示引擎将用repr()函数记录所有语句及其参数列表到日志
# 由于SQLAlchemy是多线程，指定check_same_thread=False来让建立的对象任意线程都可使用。这个参数只在用SQLite数据库时设置
DB_ENGINE_KWARGS: dict = {
    # "echo": True,
    # "encoding": 'utf-8',

    "connect_args": {
        'check_same_thread': False,
        # "charset": "utf8mb4"
    }
}
# 在SQLAlchemy中，CRUD都是通过会话(session)进行的，所以我们必须要先创建会话，每一个SessionLocal实例就是一个数据库session
# flush()是指发送数据库语句到数据库，但数据库不一定执行写入磁盘；commit()是指提交事务，将变更保存到数据库文件
DB_SESSION_MAKER_KWARGS: dict = {
    "autoflush": False,
    "autocommit": False,
    "expire_on_commit": True
}

8、在根目录下新建文件 .gitignore

.idea
Desktop.ini
db.sqlite3
.DS_Store
*__pycache__*

docker 部署

1、在根目录下新建文件 Dockerfile

FROM python:3.8
WORKDIR /app
EXPOSE 80
RUN mkdir -p /app && pip install lsshu-cms
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80", "--reload"]

2、创建镜像并运行

docker build -t project_name . && docker run -d --name project_name -v /projects/project_path:/app -p 49000:80 project_name

@project_name 项目名称; /projects/project_path 项目所在的目录; 49000 宿主机端口; 80 容器端口;

3、删除容器和镜像

docker stop project_name && docker rm project_name && docker rmi project_name

nginx 部署

http {
    upstream project_server { 
        server 0.0.0.0:49000 weight=1;
    }
    server{
        listen 80;
        server_name project.com;
        index index.html index.htm;
        root /projects/project_path/dist;
        
        try_files $uri $uri/ /index.html;
        
        location /static/ {
          alias /projects/project_path/static/; #静态资源路径
        }
        
        location  ~/api|/docs|/openapi.json
        {
          proxy_pass  http://project_server;
          # 配置websocket
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection "upgrade";
          # 其它代理
          proxy_set_header Http_Referer $http_referer;
          proxy_set_header Host $host:$server_port; 
          proxy_set_header X-real-ip $remote_addr;
        }
        location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md|app|main\.py|config\.py)
        {
            return 404;
        }
    }
}

@root /projects/project_path/dist 其中dist 可为前端打包的目录；其它根据自身增减
