couchDB 401 error - javascript

I have a couchDB database called "guestbook". I first used the code below to add the a user to the "_users" database:
$scope.submit = function(){
var url = "https://sub.iriscouch.com/_users/org.couchdb.user:" + $scope.name;
console.log(url);
$http({
url: url,
method: "PUT",
data: {name : $scope.name,
password: $scope.pass,
roles: [],
type: "user"
},
withCredentials: true,
headers: {"Authorization": auth_hash(adminUsername, adminPass)}
})
.success(function(data, status, headers, config){
console.log(headers);
console.log(config);
});
}
Once the user was added to _users I used Futon to add that user as member to my "guestbook" _security document.
After that I tried to used that username and password (that was added as a member to "guestbook" _security) to get all the documents in the "guestbook" database. See code below:
$scope.login = function(){
var url = "https://sub.iriscouch.com/guestbook/_all_docs";
$http({
url: url,
method: 'GET',
params: {
include_docs: true,
},
withCredentials: true,
headers: {"Authorization": auth_hash($scope.uname, $scope.upass)}
})
.success(function(data, status, headers, config){
$scope.book = data.rows;
console.log($scope.book);
});
}
function auth_hash(username, password)
{
return "Basic" +btoa(username + ":" + password);
}
But everytime I tired access the "_all_docs" I get a 401 unauthorised error. The username I am using to access has been added as a member into the _security documents of the guestbook database.
Can anyone help. What am I doing wrong.

Do you have added the user name w/o the org.couchdb.user prefix to the _security object?
I can easily understand your code but didn't see a obviously mistake. I would recommend you test your API calls with Postman (Chrome App) or similar to know whether the problem is client- or server-side caused.

401 indicates Couch is unable to log in your user rather than it's not allowing them access to the database.
Might be a copy/paste error in writing the code example, but it looks like your line:
return "Basic" +btoa(username + ":" + password);
Is missing a space between Basic and your hash in the returned string:
return "Basic " +btoa(username + ":" + password);
This will mean that your Authorization header isn't correct.
However, your first code block appears to use the same function successfully, so I'm clutching at straws.

http basic authorization with Flask REST

I am developing a simple REST service in flask.
I have been trying to implement basic authorization.
Whilst, I can pass the username and password from the webpage using manual entry, I can't seem to read them from the header.
Here is my code:
On the server
def test():
if request.authorization and request.authorization.username == '***' and request.authorization.password == '***':
return "Authorized"
else:
return make_response('Authorization failed', 401, {'WWW-Authenticate': 'Basic realm ="Login Required"'})
On the client - using JavaScript
<script>
$(document).ready(function(){
$("#authButton").click(function(){
$.ajax({
xhrFields: {
withCredentials: true
},
headers: {
'Authorization': "Basic " + btoa("***:***")
},
url: "********:5001/",
type: 'GET',
success: function(){
console.log("success");
},
error: function (){
console.log("error");
},
});
});
});
</script
>
I have also tried the Javascript code without the xhr fields section, but for neither do I get anything returned at all.
If I don't send the headers from the client it works and simply asks for manual input of the username and password.
All I'm trying to do is authenticate from the header.
Any pointers would be very gratefully received.

Nodejs request post with body include api key

I have been trying about a week but I couldn't make a post request to get a result.
I tried a bunch of middlewares (exp: 'request', 'axios', 'reqclient','superagent etc..) but I couldn't make it.
Please provide me a simple post request with sending API key and body.
I also read all the documentation.
Please check below to see what I want :
*Authentication API key required.
*O-Auth Scopes trades
*Input One of: user_id + token or user_url is required.
here is my one of try :
const request = require('request-promise')
const options = {
method: 'POST',
uri: 'api-site.com/Offer/v1/',
headers: {
'User-Agent': 'Request-Promise',
'Authorization': 'Basic 123123asdasd123123'
},
body: {
user_url: "site.com/user/user1234123",
otherparams: "parameter"
},
json: true
};
request(options)
.then(function (response) {
Console.log(response);
})
.catch(function (err) {
console.log('Error ', err.message);
});
I am getting this output :
Error : 401 - {"status":401,"time":1540458426,"message":"API Key Required"}
I tried some other request post middle-wares and played with content-type (application/json. dataForm, x-www-form-urlencoded) or
changed the location of my API key from header to body or
tried my API key inside of auth{authorization: "API Key"}
tried much more.
the result didn't change. I got the same output or errors.
EDIT :
this is the link that I am trying to do but got stack :
check here
Solved !
Everything works great. Problem was I needed to send my API Key base64 string.
Buffer.from("your_api_key_value" + ":", "ascii").toString("base64")

AngularJS - Dynamic URL with ID

config.js
angular.module('config', []).constant('ENV',
{
name: 'My Angular Project',
apiEndPoint: 'http://SOMEIP/myServer', //API host,
adminUrl:'/admin/regionid/site/siteid/admin/regionid', //endpoint
loginUrl:'/login/regionid/site/siteid/device'
});
controller.js
this.userLogin = function(username, password) {
var adminServicePath = ENV.apiEndPoint + ENV.adminUrl
//final url = http://SOMEIP/myServer/admin/1/site/1/admin/1
var loginServicePath = ENV.apiEndPoint + ENV.loginUrl
//final url = http://SOMEIP/myServer/login/2/site/2/device
return $http({
method: 'POST',
url: adminServicePath,
headers: {
"Authorization": "Basic ",
"Content-Type": "application/x-www-form-urlencoded"
}
})
};
Here I am appending API with endpoint to form a complete URL. My issue is regiondid and siteid are dynamic. After user logs in, one REST API request will fetch siteid and regionid in response.
How do I dynamically replace siteid and regionid in URL with ID's
received in API response? After receiving id's in response, call a function that replaces the value.
You can use the String.prototype.replace(substr, newsubstr)
You can keep regionID instead of ?
var ENV = {
name: 'My Angular Project',
apiEndPoint: 'http://SOMEIP/myServer', //API host,
adminUrl: '/admin/?/site/?/admin/?', //endpoint
loginUrl: '/login/?/site/?/device'
};
var adminServicePath = ENV.apiEndPoint + ENV.adminUrl.replace("?", 1).replace("?", 1).replace("?", 1);
console.log("Final url admin : " + adminServicePath);
var loginServicePath = ENV.apiEndPoint + ENV.loginUrl.replace("?", 2).replace("?", 2);
console.log("Final url login : " + loginServicePath);
instead of constant, you can use value.
angular.module('config', []).value('ENV',
{
name: 'My Angular Project',
apiEndPoint: '', //API host,
adminUrl:'', //endpoint
loginUrl:''
});
Inject ENV and set all values after API call.
ENV.name = xyz;
ENV.apiEndPoint = xyz;
ENV.adminUrl = xyz;
ENV.loginUrl = xyz;
but the values might get set to default once you refresh the browser.
I'll assume that the siteid and the regionid can only be obtained from the response to the login endpoint.
Using a constant might not be the best idea here for obvious reasons (i.e. they're constant, and can't be created at the time you want to create them).
Instead, you could do one of a few things - a simple solution that probably works for a lot of use cases would be to create a login service that wraps your API call and then sets a value either in the service or another service that can be injected into wherever you need it.
It might look like this:
angular.module('app')
.service('loginService', function($http) {
var siteId,
regionId;
function login(username, password) {
return $http({
method: 'POST',
url: '<login endpoint here>',
headers: {
"Authorization": "Basic ",
"Content-Type": "application/x-www-form-urlencoded"
}
})
.then(function(result) {
siteId = result.siteId;
regionId = result.regionId;
});
}
);
This makes the values available to you any time you need to make an API call after logging in. However, this isn't great since you will need to inject the loginService into any controller/service that needs it, and that controller/service might not really care about the login service at all.
An improved approach to this could be to have an API service that performs the http gets/sets/puts/posts/whatever and that is accessed by your data access layer. Inside this service, you can set/get the siteid and regionid.
It might look like this:
angular.module('app')
.service('api', function($http) {
var siteId,
regionId;
var defaultHeaders = {
"Authorization": "Basic ",
"Content-Type": "application/x-www-form-urlencoded"
};
function post(url, options) {
return $http({
method: 'POST',
url: url,
headers: options.headers ? options.headers : defaultHeaders
});
}
// Other functions to perform HTTP verbs...
});
angular.module('app')
.service('loginService', function(api) {
function login(username, password) {
api.post('urlHere', options)
.then(function(result) {
api.siteId = result.siteId;
api.regionId = result.siteId;
});
}
});
You can then access the siteid and regionid where you like.
For example:
angular.module('app')
.controller('someService', function(api) {
function doSomethingWithTheApi() {
var url = 'www.google.com/' + api.siteId + '/' + api.regionId + 'whatever-else';
return api.post(url, {});
}
);
Note: the code above isn't complete, but it gives you a very good idea of the approach you could take that is reasonably clean, not too hacky and is easily testable :)
Hope that helps!

AngularJS "localStorage.getItem" is null in $resource

I have an angular $resource for login and getting user's info. The login sends the username and password to server and gets a Bearer token. In the success function of User.login the token is stored in localStorage. In getEmail, I'm including the token in header to the user's email address.
The problem is, the first time getEmail is called in controller, $window.localStorage.getItem('TK') evaluates to null but if I refresh the page then it works correctly. All of the subsequent requests to the server that have the token included work as expected. What could cause this?
Not to mention, getEmail is called way after login and I have confirmed that the token is present in localStorage before the getEmail is called.
angular.module('authentication')
.factory('User', function ($resource, $window) {
return $resource('/login', {}, {
login: {
method: 'POST'
},
getEmail: {
url: '/user',
method: 'GET',
headers: {
'Authorization': "Bearer " + $window.localStorage.getItem('TK')
}
}
});
})
In response to # comment:
My controller looks like this:
angular
.module('app.mymodule', ['ngReource', 'authentication')
.controller('myCtrl', mymodule);
mymodule.$inject = ['User', '$window'];
function mymodule(User, $window) {
// THIS PRINTS THE TK IN CONSOLE CORRECTLY
console.log($window.localStorage.getItem("CHTOKEN"));
// THIS IS UNAUTHORIZED CUZ TK IS NULL
User.getEmail({}, function(data){
console.log('set the email');
});
}
Your problem is that the resource definition is provided at the time of creation (before you have saved a token).
You can either add a general request interceptor to the $httpProvider so all requests are covered or change your getEmail action's header to use a function so it is evaluated at run time, eg
headers: {
'Authorization': function() {
var token = $window.localStorage.getItem('TK');
return token ? 'Bearer ' + token : null;
}
}

how to pass credentials with angular-http-auth?

Inside my app, authentication is working with angular-http-auth
when user fill the username / password form and submit, it targets the login() function from the controller :
$scope.login = function() {
var credentials = Base64.encode($scope.username + ':' + $scope.password);
$http.defaults.headers.common['Authorization'] = 'Basic ' + credentials;
User.login( // reference to the $resource service
function() { // success callback
authService.loginConfirmed(); // method of angular-http-auth
}
);
}
User is a service created with $resource
factory('User', function($resource){
return $resource('url/to/json',
{},
{ 'login': { method: 'GET', isArray:true }
});
})
and base64 is an encrypting service coming from here
This is working like this, but is there a way to pass the credentials through angular-http-auth instead of setting default headers through $http ?
The problem with doing this:
$http.defaults.headers.common['Authorization'] = 'Basic ' + credentials;
is that you're now setting the "credentials" for all $http requests that are made. If you don't want to do that, and you want to pass the "credentials" with each $resource call directly, you can, which is what it looks like you're starting to do there.
return $resource('url/to/json',
{},
{ 'login': {
method: 'GET',
headers: { 'Authorization': 'Basic ' + credentials }
}
});
I didn't try this very example, but I have I similar code where the method is a POST so I call save() on the result of $resource before returning it, and the 'login' key is 'save'
But since you're doing a GET, with a custom "login" method, this should work.
