How to parallelize the for loop inside a async function and track for loop execution status?

问题 Recently, I have asked a question regarding how to track the progress of a for loop inside a API deployed. Here's the link. The solution code that worked for me is, from fastapi import FastAPI, UploadFile from typing import List import asyncio import uuid context = {'jobs': {}} app = FastAPI() async def do_work(job_key, files=None): iter_over = files if files else range(100) for file, file_number in enumerate(iter_over): jobs = context['jobs'] job_info = jobs[job_key] job_info['iteration'] =

「开发者投稿」使用 Authing 对 SPA 应用进行身份认证实践

作者段清华，「最懂金融的 AI 工程师，微软 AI 领域最有价值专家（MVP），谷歌开发者专家（GDE），希望加速人类的生产力，让智能比电力与宽带更普及。」 为什么需要云身份验证和单点登录 简单来说是为了降低维护用户注册登录系统、权限、统计等各方面的成本。 应用结构简述 通过 Authing 实现身份验证和单点登录，有很多种方法，这篇文章的例子是根据自身软件架构，实现了其中一种相对简单的方法，并不适用所有情况，Authing 本身还提供了多种的登录解决方案，包括直接嵌入到网站上、APP 上的等等。 前端采用纯 React/React-router/Ant.design 开发，没用 Redux/Server Rendering 之类比较复杂的东西，就使用 create-react-app 的最基本方案，没用 TypeScript（因为懒，我有罪）。 后端采用 Python + FastAPI 的简单 API。 登录流程 第一阶段，前端 通过检测本地 localStorage，未发现保存的登录 token 信息时，提示用户需要登录，给出登录链接，用 HTML 的 a 标签直接跳转到 Authing 提供的 SSO 网址上，例如 xxxx.authing.cn ，其中 xxxx 是可以用户自定义的。 第二阶段，Authing SSO 网站 完成登录，可以自由配置，例如注册方式
