How to Pass Data in AngularJS $http.get Requests?

Passing Data in AngularJS $http.get Requests

In AngularJS, the $http.get method allows you to retrieve data from a remote server. While $http.post supports passing data in the request payload, $http.get inherently differs in its data handling mechanism.

Understanding HTTP GET Constraints

Unlike $http.post, $http.get is designed for retrieving information and doesn't have a built-in mechanism for sending data to the server. This is because GET requests are intended to be idempotent, meaning they don't modify the server's state.

Solution: Using Query String Parameters

To pass data in an $http.get request, you can utilize query string parameters. AngularJS provides a params option within the configuration object to specify these parameters.

Syntax for Passing Query String Parameters

$http({
  url: user.details_path,
  method: "GET",
  params: {user_id: user.id}
});

In this code, the params object contains the key-value pair {user_id: user.id}. When the request is sent, this data will be appended to the end of the URL as a query string, resulting in a GET request of the form:

https://example.com/user/details?user_id=123

  • [AngularJS API: $http](https://docs.angularjs.org/api/ng/service/$http#usage) (which demonstrates the use of the params parameter)
