Direct cURL access to Rails app: Bypassing Passenger in Redmine server

To bypass the Passenger Redmine server and access the Redmine REST API, you can create a script that communicates directly with the Redmine application running on the server. Here's a step-by-step guide to creating a Ruby script that interacts with the Redmine REST API.

Prerequisites:

1. Ensure that you have Ruby installed on your server.
2. Install the rest-client and json gems for making HTTP requests and handling JSON responses, respectively:

gem install rest-client json

Script:

Create a file named redmine_api.rb and paste the following code:

require 'rest-client'
require 'json'

# Your Redmine API URL (e.g., http://your-redmine-server.com/api)
api_url = "http://your-redmine-server.com/api"

# Your Redmine API key (obtain it from your Redmine account settings)
api_key = "your-api-key"

# Your Redmine API username (obtain it from your Redmine account settings)
api_username = "your-api-username"

# Function to make authenticated GET requests
def get_request(path)
  request = RestClient::Request.new(
    method: :get,
    url: api_url + path,
    headers: {
      'Content-Type' => 'application/json',
      'Authorization' => "Token token=#{api_key}"
    }
  )
  request.execute
end

# Function to make authenticated POST requests
def post_request(path, params)
  request = RestClient::Request.new(
    method: :post,
    url: api_url + path,
    headers: {
      'Content-Type' => 'application/json',
      'Authorization' => "Token token=#{api_key}"
    },
    payload: params.to_json
  )
  request.execute
end

# Example usage: list projects
puts get_request("/projects.json").body

# Example usage: create a new issue
params = {
  title: "New issue",
  description: "This is a new issue created programmatically.",
  project_id: 1
}
puts post_request("/issues.json", params).body

Replace your-api-key and your-api-username with your actual Redmine API key and username. Also, update the api_url variable with the URL of your Redmine API.

Running the script:

Execute the script using the following command:

ruby redmine_api.rb

This script demonstrates how to make authenticated GET and POST requests to the Redmine REST API. You can modify it according to your needs and use cases.
