Node.js中用soap npm调用SOAP API遇信封转换失败问题求助

调用Sabre的SSSAdvShopRQ接口时，使用Node.js的soap npm包构建参数对象后，无法转换为正确的SOAP请求信封，返回错误：

soap-env:Fault soap-env:Client.InvalidEbXmlMessage Missing <soap-env:Header> in <soap-env:Envelope> javax.xml.soap.SOAPException: Missing <soap-env:Header> in <soap-env:Envelope>

错误响应 #

soap-env:Fault
soap-env:Client.InvalidEbXmlMessage
Missing soap-env:Header in soap-env:Envelope

javax.xml.soap.SOAPException: Missing soap-env:Header in soap-env:Envelope

</soap-env:Fault>

解决方法 #

问题出在soap包的用法错误：soap包会自动生成SOAP Envelope结构，不需要手动传入整个Envelope对象，否则包无法正确识别Header部分。正确做法是拆分Header和业务参数，单独设置Header，只将业务数据作为接口参数传入。

修改后的代码 #

const bodyParser = require('body-parser');

app.listen(3000, () => {
    console.log("Server started at port 3000");

关键改动说明 #

• 将Header内容从params中拆分出来，通过client.addSoapHeader()方法单独设置，确保soap包正确将其放入SOAP Envelope的Header部分。
• params只保留业务请求体（OTA_AirLowFareSearchRQ），这是SSSAdvShopRQAsync方法需要的参数，soap包会自动将其包裹到Envelope的Body中。
• 添加了错误处理，方便排查调用中的其他问题。
