fastapi 的css js文件地址修改

from fastapi.openapi.docs import get_swagger_ui_html, get_redoc_html

点进get_swagger_ui_html修改源码

def get_swagger_ui_html(*,openapi_url: str,title: str,# swagger_js_url: str = "https://cdn.jsdelivr.net/npm/swagger-ui-dist@3/swagger-ui-bundle.js",# swagger_css_url: str = "https://cdn.jsdelivr.net/npm/swagger-ui-dist@3/swagger-ui.css",swagger_js_url: str = "https://cdn.staticfile.org/swagger-ui/5.1.0/swagger-ui-bundle.js",swagger_css_url: str = "https://cdn.staticfile.org/swagger-ui/5.1.0/swagger-ui.css",swagger_favicon_url: str = "https://fastapi.tiangolo.com/img/favicon.png",oauth2_redirect_url: Optional[str] = None,init_oauth: Optional[Dict[str, Any]] = None,
) -> HTMLResponse:html = f"""<!DOCTYPE html><html><head><link type="text/css" rel="stylesheet" href="{swagger_css_url}"><link rel="shortcut icon" href="{swagger_favicon_url}"><title>{title}</title></head><body><div id="swagger-ui"></div><script src="{swagger_js_url}"></script><!-- `SwaggerUIBundle` is now available on the page --><script>const ui = SwaggerUIBundle({{url: '{openapi_url}',"""

第二种方法
在app=FastAPI(…)之前粘贴下面代码，可以修改swagger js css 引用路径

from fastapi import applications
from fastapi.openapi.docs import get_swagger_ui_htmldef swagger_monkey_patch(*args, **kwargs):"""Wrap the function which is generating the HTML for the /docs endpoint andoverwrite the default values for the swagger js and css."""return get_swagger_ui_html(*args, **kwargs,swagger_js_url="https://cdn.staticfile.org/swagger-ui/4.15.5/swagger-ui-bundle.min.js",swagger_css_url="https://cdn.staticfile.org/swagger-ui/4.15.5/swagger-ui.min.css")# Actual monkey patch
applications.get_swagger_ui_html = swagger_monkey_patch# app = FastAPI(title="xxx",..................)
