Receiving Json data in groovy app - angularjs

I´m working on this app which will be a frontend consuming data from other applications but in first stance, it will be posting credentials to another app already running in production, and after credentials are accepted it should redirect to that app with user logged in.
Here comes the problem. I´ve already tested sending data to the other application data is being received as
params: [{"j_username":"username","j_password":"password","instance":"http:8080/TERA/authAuto"}:, action:authAuto, controller:login]
username: null
Prueba: null
I have tried to receive this as it follows all without success
request.JSON.j_username
params.j_username
params["j_username"]
The params: is actually params received by groovy being printed.
I´ll now add my angularJs code
vm.login = function(){
$http({
method: 'POST',
url: "http://t0002161750:8080/TERA/authAuto",
data: {j_username: vm.user.username, j_password: vm.user.password, instance: "http://t0002161750:8080/TERA/authAuto"},
headers:{
'Content-Type': 'application/x-www-form-urlencoded;charset=utf8'
}
}).success(function(response){
$window.location.href = "http://t0002161750:8080/TERA/";
});
}
}
Im doing this tests with a companion having the other app running on his PC.
I may be doing something wrong conceptually speaking. I know that by sending the params in the $window.location.href = url+params will work but i dont want the credentials travelling in the url. I know i can encode them but lets try something else before giving up if it is possible.

The problem here is using the wrong Content-Type for the submission. The server will look for POST-vars in the body. The proper value to use is:
Content-Type: application/json
(instead of application/x-www-form-urlencoded;charset=utf8)

Ionic to laravel post request

I have Laravel back-end API which can receive info from Ionic app. The problem I'm facing is sending an array of data through POST request...
This is my method:
Injection.ResourceFactory.postResource($http, SERVER, 'order/addToBasket', {
token: localStorage.getItem('token'),
quantity: $scope.quantity.value,
product_id: $scope.productId,
condiments: [$scope.condiments]
...
and postResource method is:
postResource: function ($http, SERVER, route, parameters, data) {
return $http({
method: 'POST',
url: SERVER + route,
data: data,
params: parameters
})
},
So everything is pretty straightforward, and works locally perfect. When I transfer everything online, suddenly the condiments aren't being sent. I have tried console logging it before and after the call, and as far as Ionic is concerned, an array is being sent...but for some reason not received?
When I make Input::all() call in Laravel i get only token, quantity and product_id. If I remove the brackets from condiments: [$scope.condiments] so that I send condiments: $scope.condiments I get only last item from the JSON being sent?
I can't seem to figure this one out...ideas?

Error 400 when POST'ing JSON in angularjs + Spark Single Page Application

I'm new to Single Page Application area and I try to develop app using angularjs and Spark framework. I get error 400 bad request when I want to post JSON from my website. Here is code fragment from client side:
app.controller('PostTripCtrl', function($scope, $http) {
$scope.newTrip = {};
$scope.submitForm = function() {
$http({
method : 'POST',
url : 'http://localhost:4567/trips/add',
data : $scope.newTrip,
headers : {
'Content-Type' : 'application/x-www-form-urlencoded'
}
}).success(function(data) {
console.log("ok");
}).error(function(data) {
console.log("error");
console.log($scope.newTrip);
});
};
});
Values that are to be assigned to newTrip are read from appropriate inputs in html file. Here is server-side fragment:
post("/trips/add", (req, res) -> {
String tripOwner = req.queryParams("tripOwner");
String startDate = req.queryParams("startDate");
String startingPlace = req.queryParams("startingPlace");
String tripDestination = req.queryParams("tripDestination");
int tripPrice = Integer.parseInt(req.queryParams("tripPrice"));
int maxNumberOfSeats = Integer.parseInt(req.queryParams("maxNumberOfSeats"));
int seatsAlreadyOccupied = Integer.parseInt(req.queryParams("seatsAlreadyOccupied"));
tripService.createTrip(tripOwner, startDate, startingPlace, tripDestination, tripPrice, maxNumberOfSeats,
seatsAlreadyOccupied);
res.status(201);
return null;
} , json());
At the end I obtain error 400 bad request. It is strange for me that when I want to see output on the console
System.out.println(req.queryParams());
I get json array of objects with values written by me on the website. However, when I want to see such output
System.out.println(req.queryParams("tripOwner"));
I get null. Does anyone have idea what is wrong here?
I think the main problem is that you are sending data to your Spark webservice with the 'Content-Type' : 'application/x-www-form-urlencoded' header. Try sending it as 'Content-Type' : 'application/json' instead, then in your Java code declare a String to receive req.body(), you'll see all your data in there.
Note: When you try to acces your data like this req.queryParams("tripOwner"); you're not accessing post data, but you're seeking for a get parameter called tripOwner, one that could be sent like this http://localhost:8080/trips/add?tripOwner=MyValue.
I would advise using postman to post a request to your server and see if it works. Try a different content type too. Try using curl and play with the various headers you are sending. 400 suggests the wrong data is being sent or expected data is missing or the data is the wrong type but based on your code you've provided I can see nothing wrong (but see below).
When your server receives a request log all request headers being received and see what changing them does. If it works in postman then you can change your client code to mirror the headers postman is using.
Does your spark server validate the data being sent before your controller code is hit? If so ensure you are adhering to all validation rules
Also on looking at your code again your client is sending the data in the post data but your server is expecting the data in the query string and not in the post data?
What happens if your server just sends a 201 response and does nothing else? Does your client get a 201 back? If so it suggests the hook up is working but there is something wrong with the code before you return a 201, build it up slowly to fix this.
Ok, I managed to cope with that using another approach. I used Jackson and ObjectMapper according to Spark documentantion. Thanks for your answers.
You can see more about that here: https://sparktutorials.github.io/2015/04/03/spark-lombok-jackson-reduce-boilerplate.html
You're probably just needed to enable CORS(Cross-origin resource sharing) in your Spark Server, which would have allowed you to access the REST resources outside the original domain of the request.
Spark.options("/*", (request,response)->{
String accessControlRequestHeaders = request.headers("Access-Control-Request-Headers");
if (accessControlRequestHeaders != null) {
response.header("Access-Control-Allow-Headers", accessControlRequestHeaders);
}
String accessControlRequestMethod = request.headers("Access-Control-Request-Method");
if(accessControlRequestMethod != null){
response.header("Access-Control-Allow-Methods", accessControlRequestMethod);
}
return "OK";
});
Spark.before((request,response)->{
response.header("Access-Control-Allow-Origin", "*");
});

"Failed to parse UUID" error message on attempting to login via TrueVault api

On attempting to login via the truvault api using angular js, I am getting this error message: Failed to parse UUID. I am passing the username, password and account_id as params. I am successful using the curl command and get the success response.
The 400 error is not described in the api docs for authorization. I am not sure about if this UUID is linked to the schema_id. Would anyone (truevault guys!!) know what I am doing wrong?
I contacted truevault support on this one. Dan helped me get through it.
I was passing the username/password/account_id as url string query parameters. I had to make two changes to the code:
1. Pass the above as form data parameters
2. add the angular-post-fix.js to my project.
(Note: I am not adding the link as there are editors who will disallow the post with links to elsewhere. It has happened in the past!)
When using Node.js, the querystring API is really useful. Just pass an object to the querystring.stringify() function, and the resulting output is ready to be sent to TrueVault for login.
Additionally, I found that adding the header 'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8' might be necessary (which is one of the things the Angular post-fix library does).
#orthodoc is right, but is kind of tricky how to actually build the request. Lets say we are using fetch with formData params, I'd like to add an example of a successful request:
...
var formData = new FormData();
formData.append('username', username);
formData.append('password', password);
formData.append('account_id', accountId);
return fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'
},
body: formData
});
...

Angular wait for a $http call to execute the next function

I had been searching for this same issue here, I found something but all that seems to not be working for me. Let me describe my scenario:
I am adding some features to a Web app done by myself, that Web app is used to manage the developing of the webpage of some customers. Each customer has a webpage and for each customer there are a list of proposals webpages and who of the designers did that proposal, fine.
The list of the developers and be able to see who did what is the new thing in the Web app and the reason of my question, so, the problem is:
Once the web app loads I get the list of developers from the DB and a list of all the customers that have a webpage. So, the next thing the web app does is auto-select the first customer of the list and show its proposals in another list. To do that, the list of the developers is needed, but as it hasnt been still loaded I get the:
Cannot read property '0' of undefined
When I want to iterate over the $scope.developers object
What I do to get the developers is a $http call like this:
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(data) {
$scope.developers = data;
});
I know $http performs async calls, but i need something that waits until the $scope.developers has the data loaded.
The problem comes when I need to use the data supposedly stored in $scope.developers but obvously its not. I tried to call the function that uses the $scope.developers inside the .success function but the same happens.
I tried to use the solution in this thread but I get the same error.
How to wait till the response comes from the $http request, in angularjs?
Any help ?? If something in my question is not clear I will try to explain it better.
Please just define $scope.developers as empty array before $http call ie
app.controller("someCtrl", function($scope, $http) {
$scope.developers = [];
//....
$http({
method: 'POST',
url: url,
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}).success(function(data) {
$scope.developers = data;
});
//..
});

Recaptcha angularjs verify user's answer

I am using the following plugin https://github.com/VividCortex/angular-recaptcha in order to use recaptcha at a login form.
I am using the following code for verification
$http({
url: 'https://www.google.com/recaptcha/api/verify',
method: 'POST',
params: {privatekey: "key", remoteip: "userip", challenge: "challenge", response: "user_answer" },
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(data) {
console.log(data);
if (valid) {
console.log('Success');
alert('Success');
} else {
console.log('Failed validation');
alert('Fail');
// In case of a failed validation you need to reload the captcha because each challenge can be checked just once
//vcRecaptchaService.reload();
}
});
But google server is not returning anything.
I updated the code but no luck.
I think you have a typo in your code:
post: 'GET'
Change that to method: 'GET' or method: 'POST'.
You can check out angular documentation on http to make sure you've written all the params right.
If this wasn't the source of your problems, you should post more details about your issue (what do you see in your networkl console for example).
Keep in mind that recaptcha validation must be done at server-side. I'm not 100% sure that you are doing that in the browser, but your code looks like it.
As Miguel Trias stated, you shall not validate directly from angularjs/javascript client, instead you should send the challenge and response field to your server and validate then.
Therefore you can use the uri you used (https://www.google.com/recaptcha/api/verify) or a plugin, e.g. if you use php see https://developers.google.com/recaptcha/docs/php. I'd prefer a plugin because it will save work.
Furthermore keep in mind that your private key should not be used in the client, this is why it is called private. It is only used to communicate between your server and the reCaptcha servers. The public key is used to communicate between your client and the reCaptcha servers.
