### 拷贝到xftp时的结构  ###

### 入口文件：main.py ###

from fastapi import FastAPI
    
    app = FastAPI()
    
    
    @app.get("/index", name="欢迎首页")
    async def index():
        return {"msg": "欢迎来到SayHello!"}

### 项目依赖： ###

具体内容可以通过pip list 命令看到：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlbnhpbmdjaGVu_size_16_color_FFFFFF_t_70 2][]

requirements.txt文件可以通过一下方法获取：

if __name__ == '__main__':
        popen = os.popen('pip list')
        with open('requirements.txt', 'w') as f:
            for index, i in enumerate(popen):
                if index > 1:
                    split = i.split(' ')
                    k = split[0].strip()
                    v = split[-1].strip()
                    f.write(k + "==" + v + '\n')

xshell进入项目文件列表路径

### 构建镜像文件（命令结尾的小点“.” 别忘记了） ###

docker build -t 项目名称 .

### 构建成功后运行容器即可： ###

docker run -d --name 新取的容器名称 -p 8000:80 刚刚构建的镜像名称
