尝试通过节点调用National Rail SOAP API时发生TypeError

我正在尝试使用node-soap访问National Rail API。

文档在这里： https : //lite.realtime.nationalrail.co.uk/OpenLDBWS/

我是SOAP的新手，所以这可能不是API的问题。 我正在得到一个types错误，无论我尝试…

TypeError：无法读取未定义的属性“Body”

以下是我用来尝试拨打电话的代码：

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); }); }); 

使用节点肥皂我也可以得到请求的信封，这是内容：

 <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头文件格式不正确，需要'<'AccessToken'>''</ AccessToken>>'缠绕它

 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)); }); });
