我有一个 Web 服务，我想调用一些方法。为此我创建:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#btnCallWebService").click(function (event) {
var wsUrl = "http://localhost:8080/services/StockQuoteService/";
var soapRequest =
'<?xml version="1.0" encoding="utf-8"?>'+
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" >' +
'<soap:Body xmlns:m="http://sample/">'+
' <m:getPrice>'+
' <m:symbol>IBM</m:symbol>'+
' </m:getPrice>'+
'</soap:Body>'+
'</soap:Envelope>';
$.ajax({
type: "POST",
url: wsUrl,
contentType: "text/xml",
dataType: "xml",
data: soapRequest,
success: processSuccess,
error: processError
});
});
});
function processSuccess(data, status, req) {
if (status == "success")
$("#response").text($(req.responseXML).find("HelloResult").text());
}
function processError(data, status, req) {
alert(req.responseText + " " + status);
}
</script>
</head>
<body>
<input id="btnCallWebService" value="Call web service" type="button" />
<div id="response" />
</body>
</html>
但是每次我都会遇到错误 parseerror 并显示“无法读取 null 的属性‘documentElement’”。但是当我从 Google Chrome 应用程序“Postman”调用我的服务时，我没有错误。如何使用 Java 脚本创建对我的 Web 服务的 SOAP 请求？
最佳答案
这仅适用于 IE。
<script language="JavaScript">
var request = new XMLHttpRequest();
request.open('POST', 'http://www.webserviceX.NET//CurrencyConvertor.asmx',true);
var m_request = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ConversionRate xmlns="http://www.webserviceX.NET/"><FromCurrency>INR</FromCurrency><ToCurrency>USD</ToCurrency> </ConversionRate> </soap:Body></soap:Envelope>'
request.setRequestHeader('Content-Type', 'text/xml');
request.send(m_request);
request.onreadystatechange = function() {
if (request.readyState == 4 && request.status == 200) {
alert("VALUE" + request.responseText);
}
}
</script>
