可以通过简单几行代码为系统增加审批功能。
支持按条件自动审批
☑️ 审批流节点无数量限制
☑️ 摒弃复杂的UI，仅通过简单几行代码实现审批功能
☑️ 支持内存流和持久化流
✅ 支持其他工作流（TODO）
以创建持久化审批流为例来介绍：
-
初始化审批流引擎
import ( "github.com/burxtx/FlowEngine/approval" ) f := approval.NewEngine(persistent.GetDB()) // 需传入 *gorm.DB 类型的数据库连接 -
定义流程节点名
需要显示指定开始和结束节点，默认第一个元素为开始节点，最后一个元素为结束节点
nodes := []string{ "创建工单", "主管审批", "总监审批", "总经理审批", ... //还可以更多 "结束", } processName := "上线提测流程" // 流程名称 -
定义各审批人，需要是个二维数组
approvers := [][]string{ {"Allen", "Penny"}, //一级审批人 {"Sussie"}, //二级审批人 {"Mikko"}, //三级审批人 ... // 还可以更多 } submitter := "chris" //申请人 -
创建审批流
fi, err := f.Create(ctx, approvers, nodes, submitter, processName) -
初始化调度器
r := scheduler.NewRule(price, GetQuota, amount, continuous, QuickApproval) // 初始化规则对象 tx := db.GetDB(ctx) s := scheduler.NewApprovalScheduler(tx, r) // 初始化审批调度器 -
执行审批
err := s.Trigger(ctx, "approver_xxx", "pass", "memo", fi)完整使用方法请参考单元测试用例
