HTTP client classΒΆ

Here’s an example of using the HTTPClient class. It’s just a script, so it can be run by executing:

c:\godot> godot -s

It will connect and fetch a website.

extends SceneTree

# HTTPClient demo
# This simple class can do HTTP requests, it will not block but it needs to be polled

func _init():

    var err=0
    var http = # Create the Client

    var err = http.connect("",80) # Connect to host/port
    assert(err==OK) # Make sure connection was OK

    # Wait until resolved and connected
    while( http.get_status()==HTTPClient.STATUS_CONNECTING or http.get_status()==HTTPClient.STATUS_RESOLVING):

    assert( http.get_status() == HTTPClient.STATUS_CONNECTED ) # Could not connect

    # Some headers

    var headers=[
        "User-Agent: Pirulo/1.0 (Godot)",
        "Accept: */*"

    err = http.request(HTTPClient.METHOD_GET,"/ChangeLog-5.php",headers) # Request a page from the site (this one was chunked..)

    assert( err == OK ) # Make sure all is OK

    while (http.get_status() == HTTPClient.STATUS_REQUESTING):
        # Keep polling until the request is going on

    assert( http.get_status() == HTTPClient.STATUS_BODY or http.get_status() == HTTPClient.STATUS_CONNECTED ) # Make sure request finished well.

    print("response? ",http.has_response()) # Site might not have a response.

    if (http.has_response()):
        # If there is a response..

        var headers = http.get_response_headers_as_dictionary() # Get response headers
        print("code: ",http.get_response_code()) # Show response code
        print("**headers:\\n",headers) # Show headers

        # Getting the HTTP Body

        if (http.is_response_chunked()):
            # Does it use chunks?
            print("Response is Chunked!")
            # Or just plain Content-Length
            var bl = http.get_response_body_length()
            print("Response Length: ",bl)

        # This method works for both anyway

        var rb = RawArray() # Array that will hold the data

            # While there is body left to be read
            var chunk = http.read_response_body_chunk() # Get a chunk
            if (chunk.size()==0):
                # Got nothing, wait for buffers to fill a bit
                rb = rb + chunk # Append to read buffer

        # Done!

        print("bytes got: ",rb.size())
        var text = rb.get_string_from_ascii()
        print("Text: ",text)
