Http Client in GDScript

Here’s the translation of the Go HTTP client example to GDScript, formatted in Markdown suitable for Hugo:

Our example demonstrates how to create a simple HTTP client in GDScript. GDScript provides excellent support for HTTP requests through the HTTPRequest node.

extends Node

func _ready():
    # Create an HTTP request node
    var http_request = HTTPRequest.new()
    add_child(http_request)

    # Connect to the request_completed signal
    http_request.connect("request_completed", self, "_on_request_completed")

    # Perform the HTTP request
    var error = http_request.request("https://gobyexample.com")
    if error != OK:
        push_error("An error occurred in the HTTP request")

func _on_request_completed(result, response_code, headers, body):
    if result != HTTPRequest.RESULT_SUCCESS:
        push_error("HTTP Request failed")
        return

    # Print the HTTP response status
    print("Response status: ", response_code)

    # Print the first 5 lines of the response body
    var response_text = body.get_string_from_utf8()
    var lines = response_text.split("\n")
    for i in range(min(5, lines.size())):
        print(lines[i])

In this example, we’re using the HTTPRequest node to issue a GET request to a server. The request method is a convenient way to send HTTP requests.

We connect to the request_completed signal to handle the response asynchronously. This is similar to using callbacks or promises in other languages.

In the _on_request_completed function, we first check if the request was successful. Then we print the HTTP response status code.

Finally, we print the first 5 lines of the response body. In GDScript, we need to convert the response body from UTF-8 bytes to a string, then split it into lines.

To run this script, you would typically attach it to a Node in your Godot scene. The HTTP request will be initiated when the node enters the scene tree.

Note that in a real-world scenario, you might want to add more error handling and potentially use HTTPS for secure connections.
