我正在工作一个由Meteor.js开发的项目,现在我正在进行类似这样的验证
import SimpleSchema from 'simpl-schema';
const CompanySchema = new SimpleSchema({
company_name: {
type: String,
min: 5,
max: 50,
label: "Company Name"
}
});
Company.attachSchema(CompanySchema);
但是在控制台中显示如下图
但是尝试以这种方式保留“错误”时
console.log(err.Error);
正在显示
undefined
这是插入功能
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,它将生成一个native Error
。如果您记录的是name
,message
和stack
,则会显示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:
Error
Company Name must be at least 5 characters in company insert

与此相反,属性err.error
是the Meteor.Error
的一部分,如果在Meteor Method内插入失败,则抛出该属性。
例如以下代码就是这种情况:
Meteor.call('someInserMethod', { company_name: 'abc' }, (err, res) => {
console.log(err) // this error is a Meteor.Error
})
