解决方式，在主程序中替换下载swagger静态资源的url

from fastapi import applications
from fastapi.openapi.docs import get_swagger_ui_html

def swagger_monkey_patch(*args, **kwargs):
    return get_swagger_ui_html(
        *args,
        **kwargs,
        swagger_js_url="https://cdn.bootcdn.net/ajax/libs/swagger-ui/5.6.2/swagger-ui-bundle.js",
        swagger_css_url="https://cdn.bootcdn.net/ajax/libs/swagger-ui/5.6.2/swagger-ui.min.css",
    )
applications.get_swagger_ui_html = swagger_monkey_patch
```from fastapi import applications
from fastapi.openapi.docs import get_swagger_ui_html

def swagger_monkey_patch(*args, **kwargs):
    return get_swagger_ui_html(
        *args,
        **kwargs,
        swagger_js_url="https://cdn.bootcdn.net/ajax/libs/swagger-ui/5.6.2/swagger-ui-bundle.js",
        swagger_css_url="https://cdn.bootcdn.net/ajax/libs/swagger-ui/5.6.2/swagger-ui.min.css",
