小编St.*_*mer的帖子

我正在尝试为俄罗斯帖子写一个客户端来跟踪.它使用SOAP WSDL.我至少得到客户端对象.

 'use strict'
let soap=require('soap'),
url = 'https://tracking.russianpost.ru/rtm34?wsdl',
argums={}

soap.createClient(url,argums,function(err, client){
    console.log(client) 
})

但它返回错误

    this.element = schema.elements[nsName.name];
                         ^

TypeError: Cannot read property 'elements' of undefined

任何人都可以解释它是什么以及应该要求的样子？
