如何在Angularjs中使用SOAP Webservice

Question

我想使用angularjs $ http服务

来使用以下网络服务

我尝试了以下代码，

               $scope.btnSignIn =  function(){
                   var soapRequest = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"'+
                        'xmlns:v="http://incometaxindiaefiling.gov.in/ditws/TaxCredMismatch/v_1_0">'+
                        '<soapenv:Header/>'+
                        '<soapenv:Body>'+
                        '<v:getTaxCredMismatchRequest>'+
                        '<LoginInfo>'+
                        '<userName>AJAPA5685E</userName>'+
                        '<password>pass123</password>'+
                        '</LoginInfo>'+
                        '<UserInput>'+
                        '<panNo>AJAPA5685E</panNo>'+
                        '<asseessmentyear>2014-15</asseessmentyear>'+
                        '</UserInput>'+
                        '</v:getTaxCredMismatchRequest>'+
                        '</soapenv:Body>'+
                        '</soapenv:Envelope>';
                    $http({
                        method: 'POST',
                        url: 'https://incometaxindiaefiling.gov.in/eFilingWS/ditws/getTaxCredMismatchRequest.wsdl',                            
                        data: soapRequest,
                        headers: {'Content-Type': 'application/xml'}                            
                    }).success(function(data,status, headers, config) { 
                        console.log(data);

                    }).error(function(data, status, headers, config,statusText) {

                    });                       
               }; 

但是得到了回复

XMLHttpRequest cannot load https://incometaxindiaefiling.gov.in/eFilingWS/ditws/getTaxCredMismatchRequest.wsdl. Response for preflight has invalid HTTP status code 405 

请让我知道我做错了什么。
