FastAPI(27)- Handling Errors 处理错误 前言 许多情况下,需要向客户端返回一些特定的错误,比如 客户端没有足够的权限进行该操作 客户端无权访问该资源 客户端尝试访问的项目不存在 HTTPException 介绍 要将带有错误的 HTTP 响应(状态码和响应信息)返回给客户端,需要使用 HTTPException...
FastAPI(27)- Handling Errors 处理错误 (下) 重写默认异常处理程序 FastAPI 有一些默认的异常处理程序 比如:当引发 HTTPException 并且请求包含无效数据时,异常处理程序负责返回默认的 JSON 响应 可以使用自己的异常处理程序覆盖(重写)这些默认的异常处理程序
ErrorHandlingMiddleware(错误处理中间件): 用于捕获和处理请求处理过程中的异常,返回统一的错误响应。 用法示例: class ErrorHandlingMiddleware(BaseHTTPMiddleware): async def dispatch(self, request: Request, call_next): try: response = await call_next(request) ...

# Unexpected error handling 记录错误(req_id, {'错误消息': 'ERR_UNEXPECTED'}) return 抛出 HTTPException(status_code=500, detail='ERR_UNEXPECTED') 我们可以用一个类来定义日志参数,包括请求中的各种参数。请求信息将从RequestInfo中提取,包括来自请求的各种参数。
