使用 SimpleSchema 在 Meteor.js 中处理错误

Error handling in Meteor.js with SimpleSchema

我正在做一个由 Meteor.js 开发的项目,现在我正在做类似的验证工作

import SimpleSchema from 'simpl-schema';

const CompanySchema = new SimpleSchema({
    company_name: {
        type: String,
        min: 5,
        max: 50,
        label: "Company Name"
    }
});

Company.attachSchema(CompanySchema);

但在控制台中显示如下图

但是当试图以这种方式保持 "Error" 时

console.log(err.Error);

正在显示

undefined

这里是插入功能

Company.insert(
    {
        company_name: inputs.companyName.value,
    },
    function(err) {
        if (err) {
            console.log(err);
        } else {
            console.log('Inserted successfully');
        }
    }
);

实际上是什么问题。

谢谢

当您的客户端 Mongo 插入失败时,它会生成 native Error。如果您记录它是 namemessagestack,它会显示 Error:

的预期属性
Company.insert(
    {
        company_name: inputs.companyName.value,
    },
    function(err) {
        if (err) {
            console.log(err.name);
            console.log(err.message);
            console.log(err.stack);
        }
    }
);

产生:

相比之下,属性 err.errorthe Meteor.Error, which is thrown if the insert fails inside a Meteor Method 的一部分。

例如在这样的代码中就是这种情况:

Meteor.call('someInserMethod', { company_name: 'abc' }, (err, res) => {
  console.log(err) // this error is a Meteor.Error
})
