Question

我正在使用Node.js模块“ soap”来调用SOAP服务。它可以与某些示例服务配合使用，例如：http://www.dneonline.com/calculator.asmx?wsdl

但是，我在对客户服务进行SOAP调用时遇到此错误，但我不明白为什么，也许是不兼容问题？，另一个人已经问过类似的问题，但没有答案（Target namespace "undefined" already in use by another Schema）：

Target-Namespace "undefined" already in use by another Schema!
/temp/soap/node_modules/soap/lib/wsdl.js:499
    this.element = schema.elements[nsName.name];
                         ^

SOAP端点（只能通过我的IP访问）位于：http://103.226.108.150:7003/MobileOTM/Business/TruckingEvent?wsdl

这是SOAP端点：

手动解决方案：

由服务URL描述的XML在某些“模式”标记中缺少“ targetNamespace”属性。

从URL下载XML文件，然后将“ targetNamespace”手动添加到所有“ schema”标记中。并使客户端从路径到本地文件而不是http URL。

相关答案：SOAP node returns error Target-Namespace "undefined" already in use by another Schema

无法对此特定服务，“未定义”目标名称空间进行SOAP调用
