根源就是js和ccs文件访问路由的问题，首先你要有本地的文件，详情看https://qq742971636.blog.csdn.net/article/details/134587010。

其次，你需要这么写：

/unicontorlblip就是我配置的mLB网关路由。

app = FastAPI(title='outpainting_captioning_upscaler',description='outpainting images, captioning images,upscaler images',version='1.0.0',docs_url=None,redoc_url=None,  # 设置 ReDoc 文档的路径)
app.add_middleware(CORSMiddleware,allow_origins=["*"],allow_credentials=True,allow_methods=["*"],allow_headers=["*"],
)
app.mount("/static", StaticFiles(directory="static"), name="static")@app.get("/docs", include_in_schema=False)
async def custom_swagger_ui_html():return get_swagger_ui_html(openapi_url="/unicontorlblip/openapi.json",title="xx",# oauth2_redirect_url=app.swagger_ui_oauth2_redirect_url,swagger_js_url='/unicontorlblip/static/swagger/swagger-ui-bundle.js',swagger_css_url='/unicontorlblip/static/swagger/swagger-ui.css',swagger_favicon_url='/unicontorlblip/static/swagger/img.png',)
