adnanh webhook是一个很不错的webhook 实现，方便灵活。
adnanh webhook 支持以下功能：

接收请求
解析header 以及负载以及查询变量
规则检查
执行命令
下面进行简单的参数传递测试

环境准备

参考git https://github.com/rongfengliang/adnanh-webhook-docker-compose

docker-compose

version: "3"
services:
  webhook:
    image: almir/webhook
    command: ["-verbose", "-hooks=/etc/webhook/hooks.json","-hotreload"]
    volumes:
    - "./hooks.json:/etc/webhook/hooks.json"
    - "./shell/:/shells/"
    ports:
    - "9000:9000"

hooks 文件

[
    {
      "id": "simple-one",
      "execute-command": "/shells/app",
      "include-command-output-in-response":true,
      "include-command-output-in-response-on-error":true,
      "command-working-directory":"/shells",
      "pass-arguments-to-command":
    [
      {
        "source": "payload",
        "name": "id"
      },
      {
        "source": "url",
        "name": "token"
      }
    ],
      "trigger-rule":
      {
        "match":
        {
          "type": "value",
          "value": "42",
          "parameter":
          {
            "source": "url",
            "name": "token"
          }
        }
      }
    }
  ]

shell 脚本

#!/bin/sh
echo $@ , $1, $2

说明

对于请求参数包含token=42 的才会执行shell 命令，同时将url 参数token 以及payload（post请求）中的id，传递给shell
同时配置了将shell 结果输出到响应，从运行模式来看就类似当前serverless框架的运行原理。

测试

不符合wehook rule

curl -X POST \
  'http://localhost:9000/hooks/simple-one?token=44' \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/json' \
  -H 'postman-token: 85f3425b-a0a7-cf80-c49a-87299d905a6c' \
  -d '{
 "id":"dalongdemo"
}'
Hook rules were not satisfied

规则匹配

curl -X POST \
  'http://localhost:9000/hooks/simple-one?token=42' \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/json' \
  -H 'postman-token: 76d20d8d-a72e-9ae4-2570-115f57479116' \
  -d '{
 "id":"dalongdemo"
}'
dalongdemo 42 , dalongdemo, 42
