我在从Angular 7和Typescript的不同页面发送多个请求时遇到问题。
示例:
我有一个名为Email的页面,从该页面我需要一次发送1000封电子邮件,并在变量中更新状态,这应在后台完成(一旦我单击Send,然后应关闭Email表单),然后我已导航到另一个页面来做我的其他事情(将数据提取或发布到另一个API),在这种情况下,直到完成上一个(电子邮件)请求之前,我无法调用第二个API请求。
下面是我发送给APi的代码
public SendMultileEmails(Emaildata: any, Listcount: number) {
if (Emaildata != undefined && Emaildata != [] && Emaildata != '') {
if (Listcount >= this.Emailcount) {
var Invoice = Emaildata[this.Emailcount];
var transactionName = Invoice.transactionName;
var salesHeaderID = Invoice.salesHeaderID;
var customerurl = '/Api/MultipleEmail?trnasactiontype=' + transactionName + '&Headerid=' + salesHeaderID;
this.http.get(customerurl)
.subscribe(result => {
this.Emailcount = this.Emailcount + 1;
this.SentEmailcount = this.Emailcount;
this.SendMultileEmails(Emaildata,Listcount);
},
err => console.log(err)
);
}
}
}
有没有一种方法可以执行此任务。请引导我。
谢谢
维克多。

我认为您想做些类似的事情:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Random Word Generator</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script type="text/javascript"></script>
<script language="javascript" src="update.js" type="text/javascript"></script>
<script language="javascript" src="words.js" type="text/javascript"></script>
</head>
<body onload="updateChat();">
<p id=shownword></p>
<form action="" method="post">
<input type="submit" name="word"
class="button" value="a" id="a"/>
<input type="submit" name="word"
class="button" value="b" id="b"/>
</form>
<?php
//This function gets called when button is pushed
function postword(){
$fp = fopen('word.txt', 'w');
fwrite($fp, $_POST['word']);
fclose($fp);
echo '<script type="text/javascript">',
'firstLetterSearch(';
echo $_POST['word'];
echo ');',
'</script>';
}
//When the button is pushed, the function will be called
if (isset($_POST['word'])) {
postword();
//return;
}
?>
</body>
</html>
