所有
我使用我的SOAP API使用java脚本.
这个例子说明如何使用js发送单个soap请求
var symbol = "MSFT";
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST","http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4) {
alert(xmlhttp.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string,convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}
}
xmlhttp.setRequestHeader("SOAPAction","http://www.webserviceX.NET/GetQuote");
xmlhttp.setRequestHeader("Content-Type","text/xml");
var xml = '<?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> ' +
'<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
xmlhttp.send(xml);
// ...Include Google and Terracoder JS code here...
现在我想一次发送多个soap请求(平均请求多个信封).
解决方法
只要XMLHttpRequest.open中的第三个参数设置为true,调用将是异步的.所以你应该能够发送一个新的没有太多的努力.您需要一个新的XMLHttpRequest对象才能正常工作.
如果要使用相同的回调函数,您可以将其定义为函数,并使用它来处理请求对象.
function soapCallback() {
if (this.readyState == 4) {
alert(this.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(this.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string,convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}
}
var symbol = "MSFT";
var xml = '<?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> ' +
'<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
var xmlhttp1 = new XMLHttpRequest();
xmlhttp1.open("POST",true);
xmlhttp1.onreadystatechange=soapCallback;
xmlhttp1.setRequestHeader("SOAPAction","http://www.webserviceX.NET/GetQuote");
xmlhttp1.setRequestHeader("Content-Type","text/xml");
xmlhttp1.send(xml);
var xmlhttp2 = new XMLHttpRequest();
xmlhttp2.open("POST",true);
xmlhttp2.onreadystatechange=soapCallback;
xmlhttp2.setRequestHeader("SOAPAction","http://www.webserviceX.NET/GetQuote");
xmlhttp2.setRequestHeader("Content-Type","text/xml");
xmlhttp2.send(xml);
