當試圖通過節點調用國家鐵路SOAP API時出現TypeError

Question

我試圖使用node-soap訪問國家鐵路API。

文檔是在這裏：https://lite.realtime.nationalrail.co.uk/OpenLDBWS/

我是新來的SOAP所以這可能無法與API的問題。我正在用我的任何嘗試類型錯誤......

TypeError: Cannot read property 'Body' of undefined

這裏是我使用的嘗試撥打電話代碼：

var soap = require('soap'); 
var url = 'https://lite.realtime.nationalrail.co.uk/OpenLDBWS/wsdl.aspx?ver=2014-02-20'; 
var soapHeader = '<com:AccessToken>MY_TOKEN</com:AccessToken>'; 

soap.createClient(url, function(err, client){ 

    var args = { 
    numRows : 10, 
    crs : 'LAN' 
    }; 

    client.addSoapHeader(soapHeader); 

    client.GetDepartureBoard(args, function(err, result){ 
    if(err){ 
     console.log('error!'); 
     throw err; 
    } 
    console.log(result); 
    }); 
}); 

使用節點皁我還可以得到請求包絡，這是內容：

<soap:Envelope 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:tns="http://thalesgroup.com/RTTI/2014-02-20/ldb/" 
    xmlns:tok="http://thalesgroup.com/RTTI/2013-11-28/Token/types" 
    xmlns:ct="http://thalesgroup.com/RTTI/2007-10-10/ldb/commontypes" 
    xmlns:ldbt="http://thalesgroup.com/RTTI/2012-01-13/ldb/types" 
    xmlns:ldbt2="http://thalesgroup.com/RTTI/2014-02-20/ldb/types"> 
    <soap:Header> 
     <com:AccessToken>MY_TOKEN</com:AccessToken> 
    </soap:Header> 
    <soap:Body> 
     <tns:GetDepartureBoardRequest 
      xmlns:tns="http://thalesgroup.com/RTTI/2014-02-20/ldb/" 
      xmlns="http://thalesgroup.com/RTTI/2014-02-20/ldb/"> 
      <tns:numRows>10</tns:numRows> 
      <tns:crs>LAN</tns:crs> 
     </tns:GetDepartureBoardRequest> 
    </soap:Body> 
</soap:Envelope> 

Answer 1

你的SOAP標頭被不正確地格式化，它需要 '< '的accessToken'>' '< '/的accessToken'>' 包裹在它周圍

var args, soap, soapHeader, url; 

soap = require('soap'); 

url = 'https://lite.realtime.nationalrail.co.uk/OpenLDBWS/wsdl.aspx?ver=2014-02-20'; 

soapHeader = '<AccessToken><TokenValue>Your access token</TokenValue></AccessToken>' 

// or you can write it as an object 
//soapHeader = { 
// AccessToken: { 
//  TokenValue: "Your access token" 
// } 
//}; 

args = { 
    numRows: 10, 
    crs: 'BSK' 
}; 

soap.createClient(url, function(err, client) { 
    client.addSoapHeader(soapHeader); 
    return client.GetArrivalDepartureBoard(args, function(err, result) { 
     return console.log(JSON.stringify(result)); 
    }); 
});
