我想编写一个异步JSON联系人，它将覆盖我的data.json文件的内容

Question

I have written the file contact.js using jsonfile.writeFile.

Here's my contact.js code:

var Contact = {}
Contact.saveContacts=function(contacts,done){
var jsonfile = require('jsonfile')
jsonfile.writeFile('data.json',contacts, done, function(err){
done(err)
})
}
module.exports=Contact

Here's test.js

var contacts = [ { name: "John Smith", number: "604-123-9090" } ]
Contact.saveContacts(contacts, function(err) {
console.log('success')
  })

I get the following error:

Error: Contact.saveContacts did not write any data or the written data is incorrect.

How can I solve this?

Answer 1

You can write your contact.js like below:

Contact.saveContacts = function(contacts, done) {
var jsonfile = require('jsonfile');

jsonfile.writeFile('data.json', contacts, done);

}

And your test.js like you wrote.

I hope I've helped.

 var Contact = {}

 jsonfile.writeFile('data.json',contacts,function(err){
 done(err)
 })
