TODO:

• HTTPS not supported.
• sending raw_array not supported by godot master.
• change default transformation not supported.
• pass headers not supported.
• headers are static inside the script.

Errors:

The error code on internal errors is always 404.

The response["body"] contains an error description

"Parse Error unsupported body type"
"Connection error, can't reach host"
"Request failed, invalid params?"

How to use

Is creating a connection for each request and block until response arrives.

var http = load("res://http.gd").new()

var response = http.get(url)

var response = http.put(url, body) # body can be String or RawArray

var response = http.post(url, body) # body can be String or RawArray

var response = http.delete(url)

Async - Is creating a connection and thread for each request.

var http = load("res://http.gd").new()

var ref = funcref(self, "_send")

http.getAsync(url, ref)

http.putAsync(url, ref, body) # body can be String or RawArray

http.postAsync(url, ref, body) # body can be String or RawArray

http.deleteAsync(url, ref)

func _send(response):
	pass

Response

The response is a Dictionary and contains the following fields.

response["code"]

response["headers"]

response["body"]

Body

The body is automatically transformed to a 'Variant', following types are supported by default:

"application/json" - A Json String, will return a Dictionary 
"text/plain" - Simple text, will return a String
"text/html" - Simple text, will return a String
"bytestream" - A bytestream, that can contain any data(files,images,..), will return a RawArray()

Headers don't need the Content-Length header, this is beeing added by godot HTTPClient.
