父组件调用函数式子组件，并向子组件传递函数参数。
1， 父组件
调用子组件时，传递参数：函数
import useApprovalFlow from "/@/hooks/useApprovalFlow";
const {
getApproveBackSteps,
waitForApprove,
IsSaleManager,
flowStatus,
curFlowId,
stepCanEscalation,
waitApproveStepInfo,
operAuth,
execPointerId,
approveStepName,
workflowGuid,
lastestSteps,
allSteps,
backSteps
} = useApprovalFlow(
props.fn.resolveFunc,
props.fn.getFunc,
props.fn.getBackStepFunc
);2. 子组件
定义函数：
export default function (
resolveApproveFunc: Function,
getApproveStepsFunc?: Function,
getBackStepFunc?: Function
) {
const approvePost = async (
businessId: string,
data: Object,
successCb: () => void,
failCb?: () => void
) => {
const loading2 = ElLoading.service({});
try {
const { Code, Message } = await resolveApproveFunc(b
