使用 Gunicorn + Nginx 部署 FastApi 项目实战

FastApi项目

　　项目比较简单，登录、注册生成token，redis设置有效期保存，后续操作依赖headers中的token进行认证

项目目录

api目录　　　　 接口

conf目录　　　　配置

public目录　　　异常类、字段验证、token生成

sql_app目录　　数据库操作

dependencies.py token验证

gunicorn.py　　 gunicorn配置文件

main.py　　　　项目主文件

使用UUID

import uuid


def get_id():
    return uuid.uuid4().hex

from sqlalchemy import Boolean, Column, ForeignKey, Integer, String, Text, DateTime
from sqlalchemy.orm import relationship
from datetime import datetime

from sql_app.database import Base
from public.public import get_id


class User(Base):
    __tablename__ = "users"

    id = Column(String(32), default=get_id, primary_key=True, index=True)  # 使用uuid
    name = Column(String(20), index=True)
    zh_name = Column(String(20), default=None)
    email = Column(String(50), default=None)
    hashed_password = Column(String(100))
    is_active = Column(Boolean, default=True)
    is_superuser = Column(Boolean, default=False)
    is_delete = Column(Boolean, default=False)
    description = Column(Text, default=None)
    last_login = Column(DateTime, default=datetime.now, onupdate=datetime.now)
    create_date = Column(DateTime, default=datetime.now)

    project = relationship("Project", back_populates="users")

relationship查询

class Project(Base):
    __tablename__ = "project"

    id = Column(String(32), default=get_id, primary_key=True, index=True)
    name = Column(String(20), index=True)
    description = Column(Text, default=None)
    is_delete = Column(Boolean, default=False)
    update_date = Column(DateTime, default=datetime.now, onupdate=datetime.now)
    create_date = Column(DateTime, default=datetime.now)

    users_id = Column(String(32), ForeignKey("users.id")) # 设置外键
    sign_id = Column(String(32), ForeignKey("sign.id"))

    sign = relationship("Sign", back_populates="project")
    users = relationship("User", back_populates="project") # relationship 关联

效果

redis

from aioredis import Redis, create_redis_pool # aioredis 版本需要是1.3.1，不能为2.0以上


async def get_redis_pool() -> Redis:
    redis = await create_redis_pool(f"redis://:@127.0.0.1:6379/0", encoding="utf-8")
    return redis


@app.on_event("startup")
async def startup_event():
    app.state.redis = await get_redis_pool()


@app.on_event("shutdown")
async def shutdown_event():
    app.state.redis.close()
    await app.state.redis.wait_closed()

部署到服务器

1.阿里云和宝塔开放使用端口

2.Gunicorn 启动命令：gunicorn -c gunicorn.py main:app -k uvicorn.workers.UvicornWorker

3.配置Nginx
