关于python:局域网环境生成fastapi接口文档的方法

fastapi 主动生成的接口文档, 基于 Swagger UI, 然而在外部局域网环境无法访问 cdn, 因而无奈主动生成 docs 接口文档.

如果要在内网环境生成 docs 接口文档, 须要批改示例代码如下:

from fastapi import FastAPI
import os
from fastapi.openapi.docs import (
    get_redoc_html,
    get_swagger_ui_html,
    get_swagger_ui_oauth2_redirect_html,
)
from fastapi.staticfiles import StaticFiles

app = FastAPI(docs_url=None, redoc_url=None)


root = os.path.abspath(os.path.join(os.path.basename(__file__), "../.."))
print(root)

app.mount("/static", StaticFiles(directory=f"{root}/static"), name="static")


@app.get("/docs", include_in_schema=False)
async def custom_swagger_ui_html():
    return get_swagger_ui_html(
        openapi_url=app.openapi_url,
        title=app.title + "- Swagger UI",
        oauth2_redirect_url=app.swagger_ui_oauth2_redirect_url,
        swagger_js_url="/static/swagger-ui-bundle.js",
        swagger_css_url="/static/swagger-ui.css",
    )


@app.get(app.swagger_ui_oauth2_redirect_url, include_in_schema=False)
async def swagger_ui_redirect():
    return get_swagger_ui_oauth2_redirect_html()


@app.get("/redoc", include_in_schema=False)
async def redoc_html():
    return get_redoc_html(
        openapi_url=app.openapi_url,
        title=app.title + "- ReDoc",
        redoc_js_url="/static/redoc.standalone.js",
    )


@app.get("/users/{username}",
    tags=["test"],
    name="TESTROUTER",
    description="TESTROUTER",
)
async def read_user(username: str):
    return {"message": f"Hello {username}"}


if __name__ == '__main__':
    import uvicorn

    uvicorn.run(app, host="127.0.0.1", port=8000)

注: 须要把 swagger-ui.css 和 swagger-ui-bundle.js 放到 static 文件夹下, 此文件夹放在下面示例代码的上一级目录下.

Flutter 写的 app, 须要源码能够私信~~
