We map all of our external service webhooks to one IP, and forward them to internal testing servers. I thought others would have a use for something like this, so I decided to release it as open source software. 10 | 11 | ## Installation 12 | ###### Install 13 | ```bash 14 | $ go get github.com/kyledayton/requesthub/... 15 | ``` 16 | 17 | ###### Run 18 | ```bash 19 | $ export PATH=$PATH:$GOPATH/bin 20 | $ requesthub 21 | ``` 22 | 23 | This will start the server on port 54321. 24 | There are also a few command line options available: 25 | ```bash 26 | $ requesthub -h 27 | Usage of requesthub: 28 | -config="": YAML Configuration File 29 | -noweb=false: Disable the web UI 30 | -p=54321: which port to bind to 31 | -password="": HTTP Basic Auth Password for accessing hub 32 | -r=256: max requests to store 33 | -username="": HTTP Basic Auth Username for accessing hub 34 | ``` 35 | 36 | Note: To Enable Basic Auth, you must specify both username and password. 37 | 38 | ## Usage 39 | Open [http://localhost:54321](http://localhost:54321) in your browser. The index page shows a list of your hubs, and a form for creating a hub. Create a hub and it will redirect you to the hub requests page. 40 | 41 | To send requests to the hub, send any HTTP request to `http://localhost:54321/` 42 | 43 | The hub requests page shows stored requests sent to the hub. There is a clear button, which will delete all stored requests in the hub. In addition, there is a form for setting the forwarding URL of the hub. Setting a URL and clicking 'Update URL' will forward any incoming requests to the hub into the specified URL. 44 | 45 | ## Configuration 46 | RequestHub can create default hubs on startup. Simply create a YAML file with the appropriate hub names and forwarding urls, and pass it to the config option. 47 | 48 | **config.yml:** 49 | ```yaml 50 | hubs: 51 | test-hub: 52 | forward_url: 'https://www.example.com/webhook' 53 | another-hub: 54 | ``` 55 | 56 | ```bash 57 | $ requesthub -config config.yml 58 | ``` 59 | 60 | #### Reload Config 61 | Changes to the config YAML file can be reloaded on the fly by sending SIGHUP to the requesthub process. 62 | -------------------------------------------------------------------------------- /templates/show_hub.html.go: -------------------------------------------------------------------------------- 1 | package templates 2 | 3 | const( 4 | SHOW_HUB = ` 5 | 6 | 7 | RequestHub - {{.Id}} 8 | 9 | 10 | 11 | 12 | 13 | 27 | 164 | 165 | 166 | 167 | 180 | 181 |
