C# 使用HangFire

第一章：.net Framework 4.6 WebAPI 使用Hangfire
第二章：net 8使用hangfire实现库存同步任务

前言

在第一章中我介绍了如何在.net Framework 4.6 WebAPI 中使用Hangfire，实现Hangfire定时调用我们开发的API接口，但是在实际业务中调用接口往往需要处理耗时任务，如果还像第一章中的方式去调用的话就会出现请求超时的情况。今天我就以电商系统库存同步业务为例子给大家讲解如何使用hangfire调用耗时任务。
后续我也会把项目放在CSDN上供大家下载学习。

一、项目架构

项目采用微服务的方式开发，分为以下两个服务：

• HangFireServers（调用和管理后面两个服务）
• StockChangeServers（同步库存信息至电商平台）
• SkuServers（从电商平台拉取商品信息）

二、项目服务介绍

该服务用于定时调用库存同步服务。作为库存同步服务和商品SKU更新服务的管理。

HangFire服务结构解析

该服务中用到的包：

项目内结构：

HangfireCollectionExtensions 类

该类的主要作用是配置hangfire的监控面板 也就是这里的样式，还配置了用户的账户密码和Hangfire最大开启线程以及是否只读等信息。
