calls for angular http.get within other angular http.get calls

I am working on a basic angular $http.get request that returns a json object. What I need is to extract the id from the response and use it for another $http.get call. The solution I have in place involves nesting another $http.get within the first one, but I feel there must be a more efficient way to achieve this. How can I effectively store the id from the jsonResponse into a variable? I am encountering some challenges with variable scope as I attempt to assign the value to a variable.

$http.get('/api/v1/foo/userinfo?thunk='+thunk+'&bar='+bar).success(function(data) {
    $scope.id = data.id
}).then(function(data){
    $scope.id = data.data.id
});

Answer №1

Have you considered monitoring your variable, such as $scope.id, using the following method:

$scope.$watch('id', function() {
       // Your HTTP request logic goes here
       $http.get(...)
});

By setting a value to $scope.id, your watch function will automatically activate.

This code snippet demonstrates the use of callbacks to enhance code readability. By wrapping your AJAX call in a function, you can make your code cleaner and more organized:

function initiateAJAX(thunk, bar, callback) {
    $http.get('/api/v1/foo/userinfo?thunk='+thunk+'&bar='+bar).success(function(data) {
        callback(data.id);
    });
}

You can then execute the function and proceed with your next HTTP request as follows:

initiateAJAX(thunk, bar, function(id) {
    $http(id).....

    });
});

Avoid using the watch() method and instead opt for callbacks. For a more sophisticated approach, consider utilizing promises to maintain organization.

var promiseOne = $http.get('/api/foo');
var promiseTwo;
promiseOne.success(function(data) {
    promiseTwo = $http.get('/api/bar/' + data.id);
});
promiseTwo.success(function() {
    //Exciting things happening here.
});
