Python 当应用程序位于两个不同的文件中时，mount函数如何在fastapi中工作？

我有两个不同的fastaoi文件。我希望将INTEGATE作为单个文件。我已经发布了我的代码。请回顾一下，让我知道你的想法和建议

main.py

from fastapi import FastAPI
from app import submain as subapi

app = FastAPI()
app.mount("/subapi", subapi)

@app.get("/app")
def read_main():
    return {"message": "Hello World from main app"}

submin.py

from fastapi import FastAPI

subapi = FastAPI()
@subapi.get("/sub")
async def read_sub():
    return {"message": "Hello World from sub API"}

错误

请告诉我如何将fastapi应用程序装载到其他位置或其他文件？

您需要使用

来自fastapi导入APIRouter

请参见以下内容：

submin.py

#!/user/bin/env python
# -*- coding: utf-8 -*-
from fastapi import APIRouter

subapi = APIRouter()

@subapi.get("/sub")
async def read_sub():
    return {"message": "Hello World from sub API"}

main.py

：

#!/user/bin/env python
# -*- coding: utf-8 -*-
from fastapi import FastAPI

import submain

app = FastAPI()
app.mount("/subapi", submain)


@app.get("/app")
def read_main():
    return {"message": "Hello World from main app"}

运行代码：

$ uvicorn main:app --reload
