I have the following:
bidAmount: {
amount: 0
},
userToken: {
token: null
},
this.$http.post('/place-bet', this.bidAmount, function(response) {
alert(response);
});
How do I send both this.bidAmount and this.userToken
I have tried this however it doesn't send correctly:
this.$http.post('/place-bet', [this.userToken, this.bidAmount], function(response) {
alert(response);
});
You should always post an object, that way you can access the variables on the server using their respective keys:
this.$http.post('/place-bet', {userToken: this.userToken, bidAmount: this.bidAmount}, function(response) {
alert(response);
});
or...
this.$http.post('/place-bet', {data:[this.userToken, this.bidAmount]}, function(response) {
alert(response);
});
Create an object in data object
new vue({
el:'#point'
data: {
newdata:{
token:'',
bidAmount:''
}
}
});
Now you can
this.$http.post('/place-bet',this.newdata, function(response) {
alert(response);
});

I'm trying to set data from an axios response but it seems to me like "this" is only in the scope of the axios function. I have tried different variations of the same code that I've seen on other posts, but none are working.
data: () => ({
storeKey: 'dayspanState',
calendar: Calendar.months(),
readOnly: false,
defaultEvents: [],
ticket_event: [],
}),
created(){
this.get_tickets();
console.log(this.ticket_event);
},
methods:
{
get_tickets(){
axios.get('/api/get_patching_tickets')
.then(function (response) {
this.ticket_event = response.data;
}.bind(this));
},
}
Second trial
created(){
var self = this;
axios.get('/api/get_patching_tickets')
.then(function (response) {
self.ticket_event = response.data;
});
console.log(this.ticket_event);
}
Any help would be appreciated.
Try rewriting your function like:
created(){
axios.get('/api/get_patching_tickets')
.then((response) => {
this.ticket_event = response.data;
}).finally(() => {
console.log(this.ticket_event);
});
/* WARNING: the following console will not work as expected
as the local value is set after the successful call
while this is fired immediately after created is called
*/
console.log(this.ticket_event);
}
The callbacks you passed to .then in axios.get are fine. I see the only problem with your code is that it logs this.ticket_event right after calling this.get_tickets() - an asynchronous operation, so it'll not log the updated value after the api call finish because this.get_tickets() operates asynchronously:
this.get_tickets(); // is an async operation
console.log(this.ticket_event); // will not get the most updated value of this.ticket_event
Try this to see if it works:
data() {
return {
storeKey: 'dayspanState',
calendar: Calendar.months(),
readOnly: false,
defaultEvents: [],
ticket_event: [],
}
},
methods: {
get_tickets() {
return axios.get('/api/get_patching_tickets')
.then(response => {
this.ticket_event = response.data;
});
}
},
created() {
this.get_tickets().finally(() => {
console.log(this.ticket_event);
});
}
I'm trying to catch the error response for #nuxtjs/auth but it doesn't seem to return anything but undefined.
It refuses to login if I include the user so I want to know why it's returning undefined.
CONFIG:
auth: {
strategies: {
local: {
endpoints: {
login: {
url: 'http://127.0.0.1:80/api/login',
method: 'post',
propertyName: 'token'
},
logout: false,
user: {
url: 'http://127.0.0.1:80/api/me',
method: 'get',
propertyName: undefined
}
},
tokenRequired: true,
tokenType: 'bearer',
}
},
plugins: [
'#/plugins/auth.js'
]
},
PLUGIN:
export default function ({ app }) {
app.$auth.onError((error, name, endpoint) => {
console.error(name, error)
});
}
VIEW FUNCTION:
- both handleSuccess and handleFailure returns undefined.
login() {
this.toggleProcessing(0);
let payload = {
username: 'admin',
password: 'admin123'
}
let handleSuccess = response => {
console.log(response);
this.toggleProcessing(0);
}
let handleFailure = error => {
console.log(error);
this.toggleProcessing(0);
}
this.$auth.loginWith('local', { data: payload }).then(handleSuccess).catch(handleFailure);
},
You can use e.response
async login() {
try {
const login = {
username: this.username,
password: this.password
}
let response = await this.$auth.loginWith('local', { data: login })
console.log('response', response)
} catch (e) {
console.log('Error Response', e.response)
}
}
I fell into the same problem and after spending some time i found out a very good way to catch the response. The solution is to use the axios interceptor. Just replace your plugin file code with the following
export default function ({$axios, $auth}){
$axios.interceptors.response.use(function (response) {
// Do something with response data
return response;
}, function (error) {
// Do something with response error
return Promise.reject(error);
});
}
I'm not sure initially what might be wrong here because I can't see the complete nuxt.config.js and your full component but here are a few things to check:
#nuxtjs/axios is installed
Both axios and auth modules are registered in the modules section of nuxt.config.js:
modules: [
'#nuxtjs/axios',
'#nuxtjs/auth'
]
Also, ensure the middleware property for auth is set in the component/page component.
Ensure you're following the documentation on this page: https://auth.nuxtjs.org/getting-starterd/setup
Ive been using try -> this.$auth.loginWith to catch error server response with #nuxtjs/auth.
login() {
const data = { form };
try {
this.$auth
.loginWith("local", { data: data })
.then(api => {
// response
this.response.success = "Succes";
})
.catch(errors => {
this.response.error = "Wrong username/password";
});
} catch (e) {
this.response.error = e.message;
}
},
Specify the token field in the nuxt.config
strategies: {
local: {
endpoints: {
login: { // loginWith
url: "auth/login",
method: "post",
propertyName: "data.token" // token field
},
user: { // get user data
url: "auth/user",
method: "get",
propertyName: "data.user"
},
}
}
},
modules: ["#nuxtjs/axios", "#nuxtjs/auth"],
Using this vue.js method to login users:
loginUser: function () {
socket.emit('loginUser', {
email: this.email ,
password: this.password
}, function() {
console.log('rooms in callback are:', rooms);
});
}
On the server the loginUser event is handled by:
socket.on('loginUser', (newuser,callback)=> {
var body = _.pick(newuser, ['email', 'password']);
console.log('body is:', body);
User.findByCredentials(body.email, body.password).then((user) => {
return user.generateAuthToken().then((token) => {
if (token) {
console.log('token was found');
let rooms = ['Cats', 'Dogs', 'Birds'];
callback(rooms);
} else {
socket.emit('loginFailure', {'msg' : 'Login failure'});
}
}).catch((e) => {
throw e;
});
}).catch((e) => {
socket.emit('loginFailure', {'msg' : 'Login failure'});
throw e;
});
});
I can see 'token was found' printed out in the console but does not recieve the rooms being printed in the browser console. I receive no errors either.
I'm wondering whetehr it is due to how vue.js methods work? And if so, if there is a way around it?
You forgot to specify rooms as argument in the callback
loginUser: function () {
socket.emit('loginUser', {
email: this.email ,
password: this.password
}, function(rooms) { // need to have rooms argument
console.log('rooms in callback are:', rooms);
});
}
Can I make a custom validation rule that returns true/false based on a AJAX request? the problem is that the validate call has finished running when the AJAX call completes.
Do I need to have the rule set/unset a boolean variable based on which the field is valid/invalid?
const isValidNameRule = {
getMessage(field)
{
return "The name must be unique."
},
validate(validatingName)
{
var formData = new FormData();
formData.append("validatingName", validatingName);
this.$http.post("/api/isValid?name=" + validatingName, formData)
.then(function (response) {
// success
return true;
}, function (response) {
// error
return false;
});
}
};
Didn't know how to work with Promises.
Eventually got it working by extending one of the official samples:
const customRule = {
getMessage(field, params, data) {
return (data && data.message) || 'Something went wrong';
},
validate(aValue) {
return new Promise(resolve => {
var formData = new FormData();
formData.append("nameFilter", aValue);
$.ajax({
type: "POST",
url: url,
data: {
action: "validate",
value: aValue,
}
}).done(function (data) {
if (!ok)
{
resolve({
valid: false,
data: {message: "Condition not met"}
});
}
else
{
resolve({
valid: !! aValue,
data: undefined
});
}
});
});
}
};
I have the following code, in my server. I'm uploading an image using mongoose and s3 and then want to redirect the user to another page but this isn't happening. (the upload is successful).
Routes.js:
{path: '/success', method: 'GET', config: controller.success} ......
controller.js:
imageUpload: {
payload: {
maxBytes: 209715200,
output: 'file',
parse: true
},
handler: function(request, reply) {
var userName = request.auth.credentials.username;
members.findMemberByUsername(userName, function(err, member){
if (err) {
return reply.view('upload', {error: err});
} else if (member) {
var IDImagePath = request.payload.uploadedIDname.path;
console.log(IDImagePath);
members.addID(member, IDImagePath, function(err1){
console.log("add id error", err1);
if (err1){
return reply.view('upload', {error: err1, member: member});
} else {
console.log("SUCCESSFUL!");
return reply.redirect('/success');
}
});
}
});
}
},
success: {
handler: function (request, reply){
request.auth.session.clear();
console.log("success handler working!!");
return reply.view('success');
}
}
The code hits both console.log("SUCCESSFUL") and console.log("success handler working!!") in the controller but the redirect doesn't take place. By the way I'm using 'Jade' as the templating language so I have a success.jade. Thanks.
I found out what the problem was. I'm using AJAX on the client side but didn't have a 'success' method to reload the page:
$('#submitID').click(function(){
var formData = new FormData($('#uploadID')[0]);
$.ajax({
url: '/api/image',
type: 'POST',
xhr: function() { // Custom XMLHttpRequest
var myXhr = $.ajaxSettings.xhr();
if(myXhr.upload){
console.log(myXhr.upload);
}
return myXhr;
},
success: function(data) {
window.location.href = "/success"
},
data: formData,
cache: false,
contentType: false,
processData: false
}, "json");
});
I needed window.location.href = "/success" to reload the page. Please note the jQuery Ajax SUCCESS method is different to my '/success' route, they just happen to be the same word.
