Introduction to the WP_REST_Request class and the set_body() method
Hello! Today we want to talk about one of the essential classes in WordPress called WP_REST_Request. Essentially, this class allows us to manage REST API requests. By using this class, we can easily send and receive data.
The set_body() method exists in this class, which is used to specify the body of a request. This body can contain data we want to send in the request. For example, the time we send data to the server, the body of the request contains the necessary information that exists in it.
Using this method is applicable when you need to send specific information along with the request to the server. This information is usually formatted in JSON. Therefore, whenever you feel that you need to send data to the API, you can use set_body().
Next, let's look at a simple example that shows how you can use set_body(). This example essentially demonstrates how we can create a new request and customize its body.
Example code for using the set_body() method
$request = new WP_REST_Request();
$request->set_body( json_encode( [ 'key' => 'value' ] ) );
Line-by-line explanation of the code
Line 1:
$request = new WP_REST_Request(); This line creates a new instance of the
WP_REST_Request class that gives us the ability to create a new request.Line 2:
$request->set_body( json_encode( [ 'key' => 'value' ] ) ); In this line, we customize the body of the request using the
set_body() method. The data is converted to JSON format to be sent correctly.
