Question

我想在我的钛项目中使用ASMX服务，因为我使用了Kitchen Sink Nook项目，它适用于货币转换器asmx webservice并且它没有认证头。

但是我的客户端webservice有身份验证标头，我在SOAP UI中测试了下面的webservice，它运行得很完美。但我没有得到Titanium SOAP Call的解决方案。

Calling_class.js

Titanium.include('suds.js');
var window = Ti.UI.createWindow({
    title:"Web Service Test",
    backgroundColor:"#FFF",
    exitOnClose:true

});
var label = Ti.UI.createLabel({
    top: 10,
    left: 10,
    width: 'auto',
    height: 'auto',
    text: 'Contacting currency rates web service...'
});

var bouton = Titanium.UI.createButton({

    title:"Test",
    bottom:20,
    height:120,
    width:135,  
});

window.add(label);


var url = "http://192.168.15.45:8082/CrmAppointments.asmx";
var callparams = {
    AppointmentNumber: 'APP-00000003-H042S5',
    UserId: '4'
};

var suds = new SudsClient({
    endpoint: url,
    targetNamespace: 'http://tempuri.org'
});

bouton.addEventListener("click", function(e){

try {
    suds.invoke('BookAppointmentFromWCF', callparams, function(xmlDoc) {
 console.log('response : '+ this.responseText);
        var results = xmlDoc.documentElement.getElementsByTagName('BookAppointmentFromWCF');
        if (results && results.length>0) {
            var result = results.item(0);
            label.text = '1 Euro buys you ' + results.item(0).text + ' U.S. Dollars.';
        } else {
            label.text = 'Oops, could not determine result of SOAP call.';
        }
    });
} catch(e) {
    Ti.API.error('Error: ' + e);
}
});
window.add(bouton);
window.open();

  // Client Configuration

    envelopeEnd: '</soap:Body></soap:Envelope>'
  },_options);

  // Invoke a web service
  this.invoke = function(_soapAction,_body,_callback) {    
    //Build request body 
    var body = _body;

    //Allow straight string input for XML body - if not, build from object
    if (typeof body !== 'string') {
      body = '<ns0:'+_soapAction+'>';
      body += convertToXml(_body, 'ns0');
      body += '</ns0:'+_soapAction+'>';
    }

    var ebegin = config.envelopeBegin;
    config.envelopeBegin = ebegin.replace('PLACEHOLDER', config.targetNamespace);

    //Build Soapaction header - if no trailing slash in namespace, need to splice one in for soap action
    var soapAction = '';
    if (config.targetNamespace.lastIndexOf('/') != config.targetNamespace.length - 1) {
      soapAction = config.targetNamespace+'/'+_soapAction;
    }
    else {
      soapAction = config.targetNamespace+_soapAction;
    }

    //POST XML document to service endpoint
    var xhr = getXHR();
    xhr.onload = function() {
      _callback.call(this, xmlDomFromString(this.responseText));
    };
    xhr.open('POST',config.endpoint);
        xhr.setRequestHeader('Content-Type', 'text/xml');
        xhr.setRequestHeader('SOAPAction', soapAction);
        xhr.send(config.envelopeBegin+body+config.envelopeEnd);
        console.log(config.envelopeBegin+body+config.envelopeEnd);
  };
}

此代码中的主要方法是var config = extend({，它是SOAP xml的客户端配置。当我执行时，我得到这个输出：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Server was unable to process request. ---&gt; Object reference not set to an instance of an object.</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>

我已经通过删除身份验证标头检查了SOAP UI以测试Web服务，它给了我与Titanium相同的确切错误。

我的问题是如何通过用户名和密码值传递身份验证标头？
