I'm working on nodejs loopback application. I've a user logged in already and and an operation requires this user to find a userById and update a field.
$scope.user = User.findById({
id: sender.id
});
$scope.user.supplierId = currUserId;
$scope.user.$save();
But its not working as required.
and I get following error:
PUT http://localhost:5000/api/users 401 (Unauthorized)
GET http://localhost:5000/api/AuthProviders/count 401 (Unauthorized)
401 while on router on login path
POST http://localhost:5000/api/users/login?include=user 400 (Bad Request)
Any help will be appreciated.
Thanks
For findById operation:
var url = 'http://localhost:3000/api/User/' + sender.id + '?access_token=h9vpJ94zqN199ENWx'
$http({
method: 'GET',
url: url
}).then(function successCallback(response) {
console.log(response);
}, function errorCallback(error) {
throw error;
});
Otherwise you can use Angular SDK which makes it much cleaner.

I am very new to angularJS.
in my angular app, there is a form for login. i checked the API login endpoint on postman and i notice it generates a token after successfully logged in.
I have a form to add blog post.
I want only logged in user can add blog post. below snippet are associate with my add blog form, currently i cant post through this form, coz, it doesn't get authenticated, even if i logged in with my login form.
but it works nice on postman.
I heard of $http header but not getting how to implement this.
It falls me in trouble for last 7 days, yet i couldnt fix this issue.
can anyone help to fix this?
Thanks
$http({
method: 'POST',
url: 'http://127.0.0.1:8000/api/v1/blog',
data: $scope.formBlogModel
}).then(function (response) {
$scope.success = 'post success'
}, function(response) {
$scope.error = "an error occured";
});
Add headers property, also you can implement interceptors:
$http({
method: 'POST',
url: 'http://127.0.0.1:8000/api/v1/blog',
data: $scope.formBlogModel,
headers: {
'Authorization': 'Bearer ' + token
}
}).then(function (response) {
$scope.success = 'post success'
}, function(response) {
$scope.error = "an error occured";
});
Although my backend is working correctly and I'm getting correct response from Postman crafted request
I can't see response in my angularJS controller. ( i execute this call inside controller to simplify situation )
$scope.click = function (auction_id) {
$http({
url: baseUrl + 'auctions/' + auction_id +'/followers',
headers: {
'Content-Type' : 'application/vnd.api+json'
},
method: 'POST'
})
.then(function(response) {
console.log(response);
})
.catch(function(response) {
return response;
});
};
I'm passing token with httpInterceptor which is working fine for the rest of my app.
URL is correct because I'm getting valid error number in console:
POST ##################/v1/auctions/172/followers
422 (Unprocessable Entity)
CategoryCtrl.js:64 undefined
64 line is that one console log in success .then(function....
Headers in (which I believe is) response headers from postman tab (third from Body in first screenshot)
Why response is undefined?
*Hashes in url code are mine.
From your REST API request, you're getting response with status 422, that means you've got a client error. Regarding your request, you have to handle a request when error will come. To handle error in asynchronous requests there is a second parameter of .then(mySuccessMethod(), myMethodOnError()) method.
More details about .then() and .catch() methods for promisses.
$scope.click = function (auction_id) {
$http({
url: baseUrl + 'auctions/' + auction_id +'/followers',
headers: {
'Content-Type' : 'application/vnd.api+json'
},
method: 'POST'
})
.then(function(response) {
console.log(response);
}, function(error) {
// Here goes your code to handle an error with status 4XX
console.log(error)
})
.catch(function(response) {
// Catch will come when you throw an error
return response;
});
};
When you made the request in Postman, you pass the token in the Auth attribute of the header in the request. In your code, you did not.
I'm getting a 405 error making a request from localhost, this is the full error:
OPTIONS http://www.myurl.com 405 (Method Not Allowed)
XMLHttpRequest cannot load http://www.myurl.com. Response for preflight has invalid HTTP status code 405
I understand the problem but the quirk is that I get this error just when I use the angular $http service:
var req = {
method: 'POST',
url: 'http://www.myurl.com',
headers: {
'Content-Type': 'application/json'
},
data: {
}
}
$http(req)
.then(function(res) {},
function(error) {});
Using XMLHttpRequest works perfectly:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(xhttp.responseText);
}
};
xhttp.open("POST", 'http://www.myurl.com', true);
xhttp.send();
I have a chrome extension to add CORS headers and it is working. I also notice that if I remove the third parameter in xhttp.open the error appears again.
¿Does anyone know the reason? ¿How can I use the angular services without get the error?
You can write like this. Because you are not sending any parameter to the url. So I think this is a good way to do this. just try it may work for you.
$http.post('http://www.myurl.com').
success(function(data) {
//success Response here
});
You need to allow OPTIONS method on your server side. Before every GET, POST, PUT, DELETE... requests an OPTIONS request is launched.
I advise you to disable your "chrome extension to add CORS", to have the same configuration of your final users.
I am working on a token implementation into Angular/.Net application. My part is the front-end. What's happening is that when UI sends a request with the expired token and the server replies with 401 I cannot intercept that before the Browser raises the Login form. As the result I cannot send a request to refresh the token. Can someone please give me an idea how that is supposed be managed? I will provide code just don't know what's to show.
Thanks
Adding code:
var response = $http({
method: "GET",
dataType: "json",
params: params,
headers: {
'Content-Type': "application/xml; charset=utf-8",
},
url: someurl
});
response = response.then(function (data) {
return data.data;
});
response.catch(function (data) {
$q.reject(data);
});
// Return the promise to the controller
return response;
The problem is that I cannot redirect on UI because Browser throws Login form before my code is hit when the server returns 401.
Make ajax request, and if you get 401 then redirect to login page.
P.s. for better understanding provide your code how you implement ajax request. Which module do you use for front-end auth? I recommend satellizer
Added:
I guess you need the following configuration on angular
var app = angular.module('App', ['satellizer'])
.config(function() {
/* your config */
}
.run(function($rootScope, $location, $auth) {
// Check auth status on each routing,
// Redirect to login page, if user is not authenticated or if token expired
$rootScope.$on('$routeChangeStart', function(event, next, current) {
if (!$auth.isAuthenticated()) {
$location.path('/auth/login');
}
});
});
I am using Revel + angular for my application. The index page is the login interface, and once you are successful, you should be directed to the dashboard.html page. The problem is once I have made a POST request, I get a GET request with my 'response body', however, I am still in the login page. I am using angular to make a post request to my restful server. However, whenever I make a POST request I get status 302 on my POST request but my GET request fetches the response for the page.
My Angular Controller
appMainLogin.controller('MainLoginForm',function($scope, $http){
$scope.user_email = null;
$scope.user_pass = null;
$scope.user_remember = true;
$scope.userLogin = function () {
var val = {
"user_email": $scope.user_email,
"user_pass": $scope.user_pass,
"user_remember": $scope.user_remember,
};
var stringify = JSON.stringify(val);
$http({
url: '/login',
method: 'POST',
data: stringify || '',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8'
}
}).success($scope.getEmailData).error($scope.httpError);
alert("error");
};
});
My routes
POST /login App.Login
GET /dash Dash.Index
I get this: 302 on the POST request
I get this: 200 OK on the GET request
On the 'response body' of the GET request (firefox debugger) I see my I intended html page but I still remain in the index page.
Why is my app not redirecting to the dashboard.html(index.html->dashboard.html) after the user enters their login credential (based on my code above)?
