标签: asp.net jquery ajax asmx soapheader

我有一份包含以下合同的网络服务:

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>

我正在尝试使用jquery调用该服务。这是我的代码:

$.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);
    }
});

但是,标题内容未传递给Web服务?我如何将标题凭据传递给我的Web服务调用?

soap:Header是XML / SOAP数据“payload”中的XML元素。这与HTTP headers不同。在合同中,SOAPAction(以及Content-Length等)是HTTP标头。

XmlHttpRequest.setRequestHeader用于指定HTTP标头。它与XML内部的任何内容(直接)无关。

Simplest SOAP example的第一个答案应该举例说明如何发出SOAP请求。注意:

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)

XML包含soap:Envelope和子元素soap:Headersoap:Body

快乐的编码。
