WP comment from Godot

ME:

WordPress and GODOT v3.6 is the topic. I need to submit a comment from GODOT app to public WordPress page. I will use WordPress application password

GPT-4o mini

To submit a comment from a Godot app to a public WordPress page using an application password, you can follow these steps:

### Prerequisites
1. **WordPress Setup**: Ensure your WordPress site is set up to accept comments and that you have enabled the REST API.
2. **Application Password**: Generate an application password in your WordPress user profile. This will be used for authentication.

### Steps to Submit a Comment

1. **Create a Godot Project**: Open Godot and create a new project.

2. **Add HTTPRequest Node**: In your scene, add an `HTTPRequest` node. This node will be used to send HTTP requests to the WordPress REST API.

3. **Script the Comment Submission**: Attach a script to your main scene or a relevant node. Here’s an example script that demonstrates how to submit a comment:

<> gdscript

extends Node

# Replace with your WordPress site URL
const WORDPRESS_URL = "https://your-wordpress-site.com/wp-json/wp/v2/comments"
# Replace with your WordPress username and application password
const USERNAME = "your_username"
const APP_PASSWORD = "your_application_password"

func _ready():
    # Call the function to submit a comment
    submit_comment("Your Name", "Your comment text here", "https://your-wordpress-site.com/post-url")

func submit_comment(name: String, comment: String, post_url: String):
    var http_request = HTTPRequest.new()
    add_child(http_request)

    var headers = [
        "Authorization: Basic " + String(base64_encode(USERNAME + ":" + APP_PASSWORD)),
        "Content-Type: application/json"
    ]

    var body = {
        "post": post_url,
        "author_name": name,
        "content": comment
    }

    var json_body = JSON.print(body)

    var err = http_request.request(WORDPRESS_URL, headers, true, HTTPClient.METHOD_POST, json_body)

    if err != OK:
        print("Error sending request: ", err)
        return

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

func _on_request_completed(result: int, response_code: int, headers: Array, body: PoolByteArray):
    if response_code == 201:
        print("Comment submitted successfully!")
    else:
        print("Failed to submit comment. Response code: ", response_code)

### Explanation of the Code
- **HTTPRequest Node**: This node is used to make HTTP requests.
- **Authorization**: The application password is encoded in Base64 along with the username for Basic Authentication.
- **JSON Body**: The comment data is structured in JSON format, including the post ID or URL, author name, and comment content.
- **Response Handling**: The `_on_request_completed` function checks the response code to determine if the comment was submitted successfully.

### Important Notes
- Ensure that your WordPress site allows comments and that the REST API is enabled.
- The `post` field in the body should contain the ID of the post you are commenting on. You can also use the post URL, but using the post ID is more reliable.
- Test the script in a safe environment before deploying it to ensure it works as expected.

### Testing
Run your Godot project, and it should attempt to submit a comment to your specified WordPress post. Check your WordPress site to see if the comment appears.

This should give you a good starting point for submitting comments from a Godot app to a WordPress site using the REST API and application passwords.

missing declaration in current class "base64_encode"

GPT-4o mini

In Godot, the base64_encode function is not directly available as a built-in function. Instead, you can use the String class to perform Base64 encoding. Here's how you can modify the script to include Base64 encoding correctly:
Updated Script

<> gdscript

extends Node

# Replace with your WordPress site URL
const WORDPRESS_URL = "https://your-wordpress-site.com/wp-json/wp/v2/comments"
# Replace with your WordPress username and application password
const USERNAME = "your_username"
const APP_PASSWORD = "your_application_password"

func _ready():
    # Call the function to submit a comment
    submit_comment("Your Name", "Your comment text here", "post_id_or_url")

func submit_comment(name: String, comment: String, post_id: String):
    var http_request = HTTPRequest.new()
    add_child(http_request)

    var headers = [
        "Authorization: Basic " + String(base64_encode(USERNAME + ":" + APP_PASSWORD)),
        "Content-Type: application/json"
    ]

    var body = {
        "post": post_id,  # Use the post ID or URL
        "author_name": name,
        "content": comment
    }

    var json_body = JSON.print(body)

    var err = http_request.request(WORDPRESS_URL, headers, true, HTTPClient.METHOD_POST, json_body)

    if err != OK:
        print("Error sending request: ", err)
        return

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

func _on_request_completed(result: int, response_code: int, headers: Array, body: PoolByteArray):
    if response_code == 201:
        print("Comment submitted successfully!")
    else:
        print("Failed to submit comment. Response code: ", response_code)

# Function to perform Base64 encoding
func base64_encode(data: String) -> String:
    var bytes = data.to_utf8()
    return bytes.base64_encode()

Key Changes

    Base64 Encoding Function: A custom base64_encode function is added to handle the encoding. It converts the input string to UTF-8 bytes and then uses the base64_encode() method available on the PoolByteArray class.
    Usage: The base64_encode function is called to encode the username and application password for the Authorization header.

Note

    Make sure to replace "post_id_or_url" with the actual post ID or URL where you want to submit the comment.
    Test the script in your Godot project to ensure it works as expected.

ME:

need fix for as PoolByteArray dont have base64_encode

GPT-4o mini

You're correct, and I apologize for the confusion. In Godot, the PoolByteArray does not have a base64_encode method. Instead, you can use the String class to perform Base64 encoding directly. Here's how to implement it correctly:
Updated Script with Base64 Encoding

<> gdscript

# Replace with your WordPress site URL
const WORDPRESS_URL = "https://your-wordpress-site.com/wp-json/wp/v2/comments"
# Replace with your WordPress username and application password

func _ready():
    # Call the function to submit a comment
    submit_comment("Your Name", "Your comment text here", "post_id_or_url")

func submit_comment(name: String, comment: String, post_id: String):
    var http_request = HTTPRequest.new()
    add_child(http_request)

    var headers = [

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

func _on_request_completed(result: int, response_code: int, headers: Array, body: PoolByteArray):
    if response_code == 201:
        print("Comment submitted successfully!")
    else:
        print("Failed to submit comment. Response code: ", response_code)

# Function to perform Base64 encoding
func base64_encode(data: String) -> String:
    var bytes = data.to_utf8()
    return String(bytes).base64_encode()

Key Changes

    Base64 Encoding: The base64_encode function now converts the input string to UTF-8 bytes and then encodes it using the String class's base64_encode() method.
    Authorization Header: The base64_encode function is called directly in the headers array to encode the username and application password.

Note

    Ensure that you replace "post_id_or_url" with the actual post ID or URL where you want to submit the comment.
    Test the script in your Godot project to ensure it works as expected.

This should resolve the issue and allow you to submit comments to your WordPress site from your Godot application.

Fix base64_encode not declared on base String

GPT-4o mini

I apologize for the confusion earlier. In Godot, the String class does not have a built-in base64_encode method. Instead, you can use the Crypto class to perform Base64 encoding. Here's how to implement it correctly:

func _on_request_completed(result: int, response_code: int, headers: Array, body: PoolByteArray):
    if response_code == 201:
        print("Comment submitted successfully!")
    else:
        print("Failed to submit comment. Response code: ", response_code)

# Function to perform Base64 encoding
func base64_encode(data: String) -> String:
    var bytes = data.to_utf8()
    return Crypto.base64_encode(bytes)

Key Changes

    Using Crypto Class: The base64_encode function now uses Crypto.base64_encode() to perform the Base64 encoding. Make sure to include the Crypto class in your project.
    Encoding Logic: The input string is converted to UTF-8 bytes before being passed to the Crypto.base64_encode() method.

Important Note

    Ensure that you have the Crypto module available in your Godot project. If you are using Godot 3.x, the Crypto class should be available by default.
    Replace "post_id_or_url" with the actual post ID or URL where you want to submit the comment.
    Test the script in your Godot project to ensure it works as expected.

This should resolve the issue and allow you to submit comments to your WordPress site from your Godot application.

I apologize for the oversight. The conditional operator ? is not valid in GDScript. Instead, you can use a simple if statement to check the conditions. Here’s the corrected version of the Base64 encoding function without using the conditional operator:

Key Changes

1. Removed Conditional Operator: The conditional operator ? has been replaced with if statements to check if the indices are within bounds before accessing the bytes.
2. Base64 Encoding Logic: The logic remains the same, but now it correctly checks for the presence of additional bytes.

Important Notes

• Make sure to replace "post_id_or_url" with the actual post ID or URL where you want to submit the comment.
• Test the script in your Godot project to ensure it works as expected.

Key Changes

1. Replaced Conditional Operators: The lines that were using the conditional operator ? have been replaced with if statements to check if the second and third bytes are available. If they are not, it appends "=" for padding.
2. Padding Logic: The padding logic is now clearly separated into if statements, making it easier to read and understand.
