我有以下合同的Web服务：

I have a web service with the following contract:

POST /Service/service.asmx HTTP/1.1
Host: xxx.xxx.xxx
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "xxx.xxx.xxx/Service/Method"

<?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:Header>
    <Request xmlns="xxx.xxx.xxx/Service/">
      <transactiontype>string</transactiontype>
      <username>string</username>
      <password>string</password>
    </Request>
  </soap:Header>
  <soap:Body>
    <Method xmlns="xxx.xxx.xxx/Service/">
      <xml>xml</xml>
    </Method>
  </soap:Body>
</soap:Envelope>

和我想打电话给使用jQuery的服务。这是我的code：

And I am trying to call the service using jquery. This is my code:

$.ajax({
    url: serverUrl + 'Method',
    type: "POST",
    dataType: "xml",
    data: { xml: "xml" },
    beforeSend: function (req) {
        req.setRequestHeader('Header', '<Request xmlns="xxx.xxx.xxx/Service/">'
                            +'<transactiontype>4</transactiontype>'
                            +'<agencyName>name</agencyName>'
                            +'<username>user</username>'
                            +'<password>pass</password>'
                            +'</Request>');                    
    },
    success: function (data) {
        alert(data.text);
    },
    error: function (request, status, errorThrown) {
        alert(status);
    }
});

然而，首标内容不传递到Web服务？我怎么会去传递头凭据我的Web服务调用？

However, the header content is not passed to the web service? How would I go about passing the header credentials to my web service call?

推荐答案

香皂：标题 是内部的XML / SOAP数据有效载荷的XML元素。这是不是一个 HTTP头不同。在合同中，的SOAPAction （连同内容长度等）是一个HTTP标头。

soap:Header is an XML element inside the XML/SOAP data "payload". This is different than an HTTP headers. In the contract, SOAPAction (along with Content-Length, etc) is an HTTP header.

XmlHtt prequest.setRequestHeader 用于指定HTTP头。它无关，与任何XML中的（直接）。

XmlHttpRequest.setRequestHeader is used for specifying HTTP headers. It has nothing to do with anything inside the XML (directly).

在最简单的例子SOAP使用Javascript第一个答案应该给予怎样的一个例子做一个SOAP请求。注：

The first answer at Simplest SOAP example using Javascript should give an example of how to make a SOAP request. Note:

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...' + etc;
xmlhttp.send(xml)

这是一个包含香皂的XML：信封的子元素香皂：标题和香皂：身体

快乐编码。
