Access Control Allows Origin in AngularJS

Access Control Allows Origin in AngularJS

AngularJS is a JavaScript-based web application framework for building single-page applications. It is a structural framework used to create the application’s front end.

The Access Control Allows Origin header specifies what domains can access the content. By default, AngularJS uses an empty string as the value, which means any domain can access it.

This header restricts which domains can access the resources and has two possible values, * and self. The asterisk (*), in this case, means that any domain can access it, while the other value self means that only pages of similar origin can access it.

In short, this is a security error. The browser will not allow the resource to be loaded unless an Access Control Allow Origin header is present.

Solution to This Security Error

Let’s discuss the solution to this error.

Regular web pages can transmit and receive data from remote servers using the XMLHttpRequest object, but the same-origin policy constrains them. Extensions aren’t as limited as they once were.

If an extension asks for cross-origin rights, it can communicate with servers outside of its origin.

To solve this error, you can use JSONP. This technique will enable you to send an AJAX request from the client to the server with JSON data by adding a script tag on the page and setting its src attribute to point at the URL of your service that returns JSON data.

var url = "paste url link here";
$http.jsonp(url)
.success(function(data){
    console.log(data);
});
