【问题描述】:
我正在运行一个 foreach 循环并尝试将数据发送到客户端。但是当它从循环中出来时,它给出了空数组,因为我已经全局声明了变量。我想单独推送loanid并将其作为响应返回这是我的代码sn-p
if (notificationType == "sms" || notificationType == "both") {
let invalidLoanID = [];
let text = ""
notificationPayload.forEach((element) => {
let checkQuery =
"select * from loan where loanid = " + "'" + element.loanid + "'";
sql
.query(checkQuery)
.then((loanResponse) => {
// console.log("------",loanResponse)
if (loanResponse.length == 0) {
text = element.loanid
invalidLoanID.push(text);
console.log("===", invalidLoanID);
}
if (loanResponse.length > 0) {
let insertQuery =
"INSERT INTO notification " +
"(loanid, userid, language, notificationmsg, createddt, expirydt, " +
"notificationtype, isFailed, failureremarks,isSMSSent) VALUES " +
"(" +
"'" +
element.loanid +
"'," +
"'" +
element.userid +
"'," +
"'" +
element.langauge +
"'," +
"'" +
"Loan no:"+ element.loanid +"; " + element.notificationMsg +
"'," +
"'" +
element.createdate +
"'," +
"'" +
element.expiryDate +
"'," +
"'" +
element.notificationType +
"'," +
+element.isFailed +
", '" +
element.failureremarks +
"', 0" +")";
}
})
.catch((err) => {
res.status(400).json({
status: 400,
message: err,
});
});
})
})
}
res.status(200).send({ 回应:“成功”, message: "消息发送成功", invalidLoanID : invalidLoanID
