使用JQuery的Ajax调用SOAP-XML Web Services(Call SOAP-XML Web Services With jQuery Ajax)(译+摘录)

假设有一个基于.Net的Web Service,其名称为SaveProduct

POST /ProductService.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://sh.inobido.com/SaveProduct" <?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>
<SaveProduct xmlns="http://sh.inobido.com/">
<productID>int</productID>
<productName>string</productName>
<manufactureDate>dateTime</manufactureDate>
</SaveProduct>
</soap:Body>
</soap:Envelope>

在客户端用jQuery的ajax调用的代码为

var productServiceUrl = 'http://localhost:57299/ProductService.asmx?op=SaveProduct'; // Preferably write this out from server side

function beginSaveProduct(productID, productName, manufactureDate){
  var soapMessage =
  '<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> \
  <SaveProduct xmlns="http://sh.inobido.com/"> \
  <productID>' + productID + '</productID> \
  <productName>' + productName + '</productName> \
  <manufactureDate>' + manufactureDate + '</manufactureDate> \
  </SaveProduct> \
  </soap:Body> \
  </soap:Envelope>';   $.ajax({
    url: productServiceUrl,
    type: "POST",
    dataType: "xml",
    data: soapMessage,
    complete: endSaveProduct,
    contentType: "text/xml; charset=\"utf-8\""
  });
  return false;
} function endSaveProduct(xmlHttpRequest, status){
$(xmlHttpRequest.responseXML)
.find('SaveProductResult')
.each(function() {
  var name = $(this).find('Name').text();
  });
}

说明:

  1. type:  发送的请求的类型-the type of request we're sending
  2. dataType:  发回的响应的类型- the type of the response will send back, 一般情况下可以是html, json等类型,但如果是一个SOAP web service,必须定义为 xml类型
  3. data:  发送给web service的实际数据
  4. complete:  function (XMLHttpRequest, textStatus) {  /* Code goes here */ }
  5. contentType: 请求的MIME content类型, 同理,如果是一个SOAP web service,必须定义为 “text/xml”
  6. endSaveProduct:现在XML数据就已经发送到web service了,一旦服务器server接受到请求并进行处理,调用endSaveProduct方法

如用jQuery处理传回的XML响应,必须理解SOAP reponse’s schema定义,SaveProduct的schema格式如下:

HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length <?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>
<SaveProductResponse xmlns="http://sh.inobido.com/">
<SaveProductResult>
<ID>int</ID>
<Name>string</Name>
<ManufactureDate>dateTime</ManufactureDate>
</SaveProductResult>
</SaveProductResponse>
</soap:Body>
</soap:Envelope>

传回的响应放在xmlHttpRequest的参数responseXML中,可以使用firebug或Dev. Tool查看,现在我们就可以使用jQuery来遍历该XML的节点并处理数据了。

补充:JSP和jQuery配合调用Web service的代码

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<script type="text/javascript"
src="<c:url value='/js/jquery-1.5.js'/>"></script>
</head>
<body>
<label for="name">姓名:</label>
<input type="text" id="name" name="name"/>
<br/>
<a href="#" id="ok">确定</a>
</body>
<script type="text/javascript">
$(function(){
$("#ok").click(function(){
var val = $("#name").val();
if($.trim(val)==""){
alert("请输入名称");
return;
}
<!--可以通过拦截器获取请求信息-->
var str = '<?xml version="1.0" encoding="UTF-8"?>'+
'<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'+
'<soap:Body><ns2:sayHello xmlns:ns2="http://first.cxf.itcast.com/">'+
'<arg0>'+val+'</arg0>'+
'</ns2:sayHello></soap:Body></soap:Envelope>';
$.ajax({
contentType:'application/xml;charset="UTF-8"',
dataType:'xml',//发送数据格式
type:'post',
url:'http://localhost:9999/cxf2.4_spring_web/ws/helloworld', //直接发向这个地址
data:str,
success:function(data){
//$(data).find("return").each(function(){
// alert($(this).text());
//}); //使用上面的方法也是可以的
var ss = $(data).find("return").first().text();
$("<div>").html(ss)
.css("border","1px solid blue")
.css({width:'50%'}).
appendTo($("body"));
$("#name").val("");
}
},"xml");//数据返回格式为xml
});
});
</script>
</html>
