Godot Rush Request

Rush Request is the easiest way of making HTTP requests with JSON in Godot 4. Inspired by the JS library Axios, it creates requests in a Promise-like way.

Installing

You can install it via the Asset Library or downloading a copy from GitHub.

Usage

Rush Request adds automatically an Autoload called RushRequest. With it you can create a client and use the basic methods to make HTTPS requests.

A simple usage would be like this:

extends Node


func _ready():
    var client: RushRequestClient = RushRequest.create_client({
        "timeout": 10,
        "base_url": "https://run.mocky.io/v3/",
        "headers": {
            "Content-Type": "application/json"
        }
    })
    
    # Makes a GET request
    var response: RushRequestResponse = await client.GET("/587c3de4-d119-4166-bd3a-a5272370a5fd")
    
    if response.is_successful():
        # Returns a Dictionary converted from JSON, if the response Content-Type is set to "application/json"
        print("Request was successful!")
        print(response.get_parsed_body())
    else:
        print("Request failed!")
        print(response.get_http_result_description())

API

RushRequest

The base class that will be added as an Autoload, so it can be used anywhere in the code.

Methods

• create_client(config: Dictionary = {}) -> RushRequestClient
  Returns a RushRequestClient, that will be used to make the requests. The parameter config is optional, but can be used to configure the client. The configurations are:
  • timeout: A float representing how much seconds the requests are going to wait for a response before returning a timeout error.
  • base_url: A URL that will be prepended to url unless url is absolute.
  • headers: Custom Dictionary of headers that will be passed on every request made with the client.

RushRequestClient

The configured object that will be used to perform the HTTP requests.

Methods

• GET(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP GET request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.

• HEAD(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP HEAD request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.

• POST(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP POST request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.
  • body: Custom Dictionary that will be transformed to JSON and sent as the request body.

• PUT(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP PUT request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.
  • body: Custom Dictionary that will be transformed to JSON and sent as the request body.

• PATCH(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP PATCH request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.
  • body: Custom Dictionary that will be transformed to JSON and sent as the request body.

• DELETE(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP DELETE request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.

• OPTIONS(url: String, config: Dictionary = {}) -> RushRequestResponse
  Makes a HTTP OPTIONS request to url. The config parameter is optional, but can be used to modify the request. The configurations are:

  • headers: Custom Dictionary of headers. Will be merge with the RushRequestClient headers.
  • params: Custom Dictionary of URL parameters.

• destroy()
  Destroys the client, freeing up the internal HTTPRequest object that is used to make the requests.

RushRequestResponse

Every HTTP request will return a RushRequestResponse.

Attributes

• body: A String that represents the whole body that was returned from the request.
• headers: A Dictionary with all the response headers.
• status_code: The HTTP status code.
• http_result: A HTTPRequest.Result returned from the original HTTPRequest object.

Methods

• is_successful() -> bool: Returns true if the request was successful.
• get_parsed_body(content_type: String = ""): Parses the response body to a Dictionary or an Array. The content_type parameter is optional, and represents the type of the response, for example, "application/json" or "application/xml". If the parameter is not present, the response headers are checked. Only JSON parsing is supported for now.
• get_http_result_description() -> String: Returns a textual description of the http_result attribute.
