TypeError：soap.createSession不是Node Js中的函数

Question

我正在通过发送SMS在Node Js和MongoDB中创建一个项目。我尝试创建一个会话，当我运行链接时，在邮递员中遇到了以上错误。

我使用了following文档来创建会话。

user.model.js

var mongoose = require('mongoose');  

var userSchema = new mongoose.Schema(
{
  name: {type: String, required: true},
  mobile: {type: String, required: true, unique:true, trim: true, sparse: true},
  password: {type: String, required: true, min: 6},

  is_verified:{type: Boolean, default:false}, // By given SMS OTP    
},
{
    timestamps:true
});

mongoose.model('User', userSchema);
module.exports = mongoose.model('User');

控制器

router.post("/register", upload.single('image'), function (req, res, next)
{    
  var args1 = {username:'username',password:'password'};
  var args = {message:'Your Number is 1234', recipients:'94717434990'};

  soap.createSession(url, function(err,client)
  {
    if(err)
      console.error(err);
    else
    {
      client.createSession(args1,args,function(err, response)
      {
        if(err)
          console.error(console.log(err));
        else
        {
          console.log("The response : " + response);
          res.send(response);
        }
      })
    }
  });    
})
