HTTP - Mirror Request

This is a simple example of a Phlow that mirrors a request to Phlow. It uses the http_server module to handle incoming HTTP requests and returns the request body as a JSON response.

main.yaml

name: Phlow Mirror Request
description: Mirror request to Phlow.
version: 1.0
main: http_server
modules:
  - module: http_server
    version: latest
steps:
  - return:
      status_code: 200
      body: !phs main
      headers:
        Content-Type: application/json

Now, you can run the Phlow using the command line. By default, Phlow will look for a main.yaml in the current directory:

phlow main.yaml

Test

You can test the Phlow by sending a request to the server. You can use curl or any HTTP client to send a request to the server.

curl -X POST http://localhost:3000/ \
  -H "Content-Type: application/json" \
  -H "X-Custom-Header: MyHeaderValue" \
  -d '{"key": "value"}'

This command sends a POST request to the server running on localhost:3000 with a JSON body and a custom header. The server will respond with the same JSON body and headers.

Expected Output

When you send the request, the server will mirror the request details in the response. For example, if you send the JSON body {"key": "value"} with custom headers, the response will look similar to this:

{
  "path": "/",
  "uri": "/",
  "client_ip": "127.0.0.1:45606",
  "query_string": "",
  "query_params": {},
  "body": {
    "key": "value"
  },
  "body_size": 15,
  "headers": {
    "content-type": "application/json",
    "x-custom-header": "MyHeaderValue",
    "host": "localhost:3000",
    "connection": "keep-alive",
    "user-agent": "curl/7.68.0",
    "accept": "*/*",
    "content-length": "15"
  },
  "method": "POST"
}
