Caddy API returns 200 but Connection refused

Help
1

1. The problem I’m having:

I am trying to build a CLL that helps folks deploy custom domains with SSL to their reverse proxy server, I want to integrate caddy; when I install caddy and run curl localhost, I get the default caddy page showing it works. Now, when i send a payload over the API, it returns 200, but it does not work and shows it fails

2. Error messages and/or full log output:

3. Caddy version:

caddy version
v2.7.5 h1:HoysvZkLcN2xJExEepaFHK92Qgs7xAiCFydN5x5Hs6Q=

4. How I installed and ran Caddy:

I followed the official docs, and it installed without issue

a. System environment:

Linux triggr 6.2.0-1013-gcp #13~22.04.1-Ubuntu SMP Wed Aug 30 20:41:15 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

b. Command:

I didn’t use command, i use the API running on 2019

c. Service/unit/compose file:

d. My complete Caddy config:

this is my code code
In this context,

domain is example.com
target is https://localhost:3000

package server

type CaddyConfig struct {
	Apps struct {

	}

	return nil
}

The error message is truncated, so I can’t effectively help.

Please see Keep Caddy Running — Caddy Documentation which has the right command to use to see your log output.

This means that you probably already have Caddy running not as a service. Make sure to stop all Caddy instances first, then restart the service so that it’s the only one running.

Make sure you never run caddy start which will start Caddy in the background not as a service.

when i try to curl again, i get this

curl: (7) Failed to connect to localhost port 80 after 0 ms: Connection refused

What’s the current config at this point? Are you sure you configured Caddy with a server that listens on port 80?

7

this is my /etc/caddy/Caddyfile

:80 {
	# Set this path to your site's directory.
	root * /usr/share/caddy

	# Enable the static file server.
	file_server

	# Another common task is to set up a reverse proxy:
	# reverse_proxy localhost:8080

	# Or serve a PHP site through php-fpm:
	# php_fastcgi localhost:9000
}

this is caddy.json file

{
  "apps": {
    "http": {
      "servers": {
        "srv0": {
          "routes": [
            {
              "handle": [
                {
                  "handler": "reverse_proxy",
                  "upstreams": [
                    {
                      "dial": "http://localhost:3001"
                    }
                  ]
                }
              ],
              "match": [
                {
                  "host": [
                    "trig.iamobinna.com"
                  ]
                }
              ]
            }
          ]
        }
      }
    }
  }
}

I has take a look at the caddy JSON from the docs and redesign the struct,

this was my solution

  "apps": {
    "http": {
      "servers": {
        "srv0": {
          "listen": [
            ":80",
            ":443"
          ],
          "routes": [
            {
              "handle": [
                {
                  "handler": "reverse_proxy",
                  "upstreams": [
                    {
                      "dial": "localhost:3001"
                    }
                  ]
                }
              ],
              "match": [
                {
                  "host": [
                    "trig.iamobinna.com"
                  ]
                }
              ]
            }
          ]
        }
      }
    }
  }
}

I added listening ports to it, and I had to remove http:// from the upstream URL

I recommend not putting both :80 and :443 on the same server. It messes up Automatic HTTPS, because it won’t be possible for Caddy to automatically add the HTTP->HTTPS redirect routes for only the HTTP server.

If you intend to serve HTTPS primarily, remove :80 from your config, and Caddy will automatically add an :80 server for the redirects. If you actually want to allow HTTP requests to reach your app (not recommended) then make two servers with copies of the same routes.

OMG, you are right, this is the issue I am facing now, I have been reading the docs checking why it is not redirecting to HTTPS, thank you

11

this is the final solution

{
  "apps": {
    "http": {
      "servers": {
        "srv0": {
          "listen": [
            ":443"
          ],
          "routes": [
            {
              "match": [
                {
                  "host": [
                    "e.iamobinna.com"
                  ]
                }
              ],
              "handle": [
                {
                  "handler": "reverse_proxy",
                  "upstreams": [
                    {
                      "dial": "localhost:3001"
                    }
                  ]
                }
              ]
            }
          ]
        }
      }
    }
  }
}

this is my refactored go code

package server

import (
	"fmt"
	"net/http"
	"encoding/json"
	"bytes"
	"strings"

)

func CaddySetup(domain, target string) error {

	target = strings.TrimPrefix(target, "http://")

	config := CaddyConfig{}
	config.Apps.HTTP.Servers.Srv0.Listen = []string{":443"}
	config.Apps.HTTP.Servers.Srv0.Routes = []struct {
		Match []struct {
			Host []string `json:"host,omitempty"`
		} `json:"match,omitempty"`
		Handle []struct {
			Handler  string `json:"handler"`
			Upstreams []struct {
				Dial string `json:"dial,omitempty"`
			} `json:"upstreams,omitempty"`
		} `json:"handle,omitempty"`
	}{
		{
			Match: []struct {
				Host []string `json:"host,omitempty"`

			}{
				{
					Host: []string{domain},
				},
			},
			Handle: []struct {
				Handler  string `json:"handler"`
				Upstreams []struct {
					Dial string `json:"dial,omitempty"`
				} `json:"upstreams,omitempty"`
			}{
				{
					Handler: "reverse_proxy",
					Upstreams: []struct {
						Dial string `json:"dial,omitempty"`
					}{
						{
							Dial: target,
						},
					},
				},
			},
		},
	}


	// Convert the configuration to JSON
	jsonData, err := json.Marshal(config)
	if err != nil {
		return fmt.Errorf("Failed to convert configuration to JSON: %v", err)
	}

	// Print the JSON to the console
	fmt.Println(string(jsonData))

	// Make a POST request to the Caddy API
	resp, err := http.Post("http://localhost:2019/load", "application/json", bytes.NewBuffer(jsonData))
	if err != nil {
		return fmt.Errorf("Failed to make request to Caddy API: %v", err)
	}
	defer resp.Body.Close()

	if resp.StatusCode != http.StatusOK {

		return fmt.Errorf("Caddy API returned non-200 status code: %d", resp.StatusCode)
	}

	return nil
