Question

我正在尝试解决此问题，但我无法执行传奇。我有两个表，一个表用于发票标题，一个用于发票项目，还有一个名为“ addItemToList”的函数来存储发票标题和发票项目。问题是，当我第一次调用函数时，saga不会一直执行作业，而函数会继续执行并调用下一个函数来存储发票项目。当我从本地存储中获取invoiceHeader值时，invoice_header_id为0，并且在发票项目表中，我存储的invoice_header_id项目为0

{"id":0,"customer_id":19,"account_number":"300-26688-22","account_date":"2020-07-18 00:00:00","payment_date":"2020-07-18 00:00:00","status":1,"price":"256.00","tax":"256.00","total":"309.76"}

react函数的代码片段是：

    if(this.state.product.length !== 0 && this.state.quantity !== 0 && this.state.itemPrice !== 0 &&
        this.state.itemPriceWithDsc !== 0 && this.state.profit !== 0 && this.state.itemTotal !== 0) {
        let edit = false
                if(this.state.items.length === 0 && JSON.parse(localStorage.getItem("input_invoice_item") === null)) {
                //function to add header details in db
                this.addInputInvoiceHeader()
            } 
        let header = JSON.parse(localStorage.getItem('input_invoice_header'))
        let item = {
            id: this.state.id,
            invoice_id: header === null ? 0 : header.id,
            product: this.state.product,
            quantity: parseInt(this.state.quantity),
            item_price: parseFloat(this.state.itemPrice).toFixed(2),
            discount: parseFloat(this.state.discount).toFixed(2),
            item_price_with_dsc: parseFloat(this.state.itemPriceWithDsc).toFixed(2),
            profit: parseFloat(this.state.profit).toFixed(2),
            item_total: parseFloat(this.state.itemTotal).toFixed(2),
        }
        }
        items.map(item => {
            if(item.id === this.state.id) {
                edit = true
            }
            return edit
        })
        if(edit) {
            this.props.editItem(item)
        } else {    
            this.props.addItemDB(item)
            this.props.addItem(item)
        }

我的传奇是：

export function* addInputInvoiceHeader(action) {
const response = yield call(addInputInvoiceHeader_api, action.payload)
if(!response && (!response.data || !response.message)) {
    return yield put(addInputInvoiceHeader_failure('Internal server error for input invoice header'))
}
if(response.status === 200) {
    localStorage.setItem('input_invoice_header', JSON.stringify(response.data))
    return yield put(addInputInvoiceHeader_success(response.data))
} else {
    return yield put(addInputInvoiceHeader_failure('Error for input invoice header'))
}

}

    yield takeEvery(invoicesConstants.ADDINPUTINVOICEHEADER_REQUEST, addInputInvoiceHeader)

等待传奇执行完成并在localStorage中写入响应
