简单任务分发系统。方便的用堆机器的方式解决资源消耗型业务

配置

  1. 服务端
pid: "/tmp/easytask.pid"
auth: false # 是否要求用户登录
addr: ":8080" # 服务监听地址和端口
mysql: "root:lhisroot@tcp(127.0.0.1:3306)/taskmanager?charset=utf8" 
log_dir: "./logs/" # 日志目录
  1. 客户端
pid: "/tmp/taskclient.pid"
task_serve_addr: "http://127.0.0.1:8080"
task_type: "download"
flow: 1
log_dir: "./logs/"

        "rid": "1111",
        "url": "asdlfkjalsdkfjal"

        "errmsg":"错误信息" 
    }

3. 更新任务

curl -v -X POST \
--cookie "gsessionid=MTU0asdf" \
-d '{
    "id": 1,
    "stat": 3,
    "remark": "asdfasdfadf"
}' \
"http://127.0.0.1:8080/updatetask"
        
成功应答:
Body:
{
    "code": 0
}
        
错误应答:
Body:
{
    "code":-1,
    "errmsg":"错误信息" 
}

4. 向服务器打招乎

工兵启动要先向服务器打招乎才能取任务,相当于注册的动作 GET /sayhi?type=任务类型名&name=工兵名字 成功返回"OK";出错返回错误信息串

5. 添加新的任务类型. 会在数据库创建相应的表
GET /newtype?name=任务类型名
成功返回"OK";出错返回错误信息串
6. 心跳. 每个工兵每5秒向服务器发一个心跳包
GET /beat?type=任务类型名&name=工兵名字
成功返回"OK";出错返回错误信息串
7. 回调参数格式
  GET http://callback.com/callback?type=任务类型&tid=任务ID&rid=记录ID&msg=错误信息
8. 其它
成功或失败状态依HTTP状态码为准, 200成功其实失败.

音视频转码任务:

1. 添加描述格式
BASE64({"fid":"文件ID", "flen":文件长度, "type":"文件类型", "url":"http://文件下载URL", "nurl":"http://转码后文件上传URL", "callback":"http://任务处理结果回调"})
2. 回调参数格式
  GET http://callback.com/callback?type=任务类型&tid=任务ID&rid=记录ID&msg=错误信息&nfid=转码后文件ID&img=转码后缩略图文件ID
