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。
