我想將數據從vue.js前端發佈到我的express/node後端。郵政似乎通過,但在後端我只是得到一個未定義的空數組。從Vue.JS發佈到Express路由器
前端:main.js
var app = new Vue({
el: '#app',
data: {
guests: [],
code: '',
showGuests: true
},
methods: {
saveGuests: function() {
$.ajax({
type: "POST",
url: '/api/rsvp/' + this.code,
data: this.guests,
success: function() {
this.showGuests = false;
// do more stuff to handle submission
},
dataType: 'json'
});
},
...
後端:
app.js
//body parser
var bodyParser = require('body-parser')
//express
var express = require('express');
// cfenv provides access to your Cloud Foundry environment
// for more info, see: https://www.npmjs.com/package/cfenv
var cfenv = require('cfenv');
// create a new express server
var app = express();
var rsvp = cloudant.db.use('rsvp');
// get the app environment from Cloud Foundry
var appEnv = cfenv.getAppEnv();
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({
extended: false
}))
// parse application/json
app.use(bodyParser.json())
// serve the files out of ./public as our main files
app.use(express.static(__dirname + '/public'));
//endpoint to post rsvp details
app.post('/api/rsvp/:code', function(req, res) {
console.log(req.body);
res.send('POST request received successfully')
});
// start server on the specified port and binding host
app.listen(appEnv.port, '0.0.0.0', function() {
// print a message when the server starts listening
console.log("server starting on " + appEnv.url);
});
的guests
陣列是由我省略另一功能填充。它看起來像這樣:
[{
fullName: "john smith",
rsvpStatus: "Not Responded"
},{
fullName: "Mr Stack Overflow",
rsvpStatus: "Yes"
}]
節點服務器上console.log
只是給我這個後一個POST嘗試:
{ undefined: [ '', '' ] }
任何幫助將是巨大的。在我發佈它們之前,我可能需要用Vue數據綁定來做些什麼?我是Vue的新手,所以幾乎肯定會做錯事情。
感謝:D
充滿數據的POST請求之前,前端側的'guests'陣列? – wostex
是的,我已經記錄,在POST請求期間,它顯示數據在前端# –
