公开 RPC 方法

公开 RPC 方法：处理操作

公开 RPC 方法将允许您与正在运行的进程进行实时交互。

这对于：

• 改变行为（例如将日志切换到调试）
• 检索数据结构
• 触发动作

快速开始

$ npm install tx2

Then create an application called rpc.js:

const tx2 = require('tx2')

tx2.action('hello', (reply) => {
  reply({ answer : 'world' })
})

setInterval(function() {
  // Keep application online
}, 100)

And start it with PM2:

$ pm2 start rpc.js

Now to trigger process actions, use the command:

$ pm2 trigger <application-name> <action-name>
# pm2 trigger rpc hello

Listing available RPC methods

To list all available RPC methods:

pm2 show <application-name>
# pm2 show rpc

Passing a parameter

To pass a parameter to the remote function, just add the param attribute to the callback:

var tx2 = require('tx2')

tx2.action('world', function(param, reply) {
  console.log(param)
  reply({success : param})
})

Restart your application and call this process function with PM2:

pm2 trigger <application-name> <action-name> [parameter]
# pm2 trigger rpc world somedata

Triggering from Web Dashboard

All RPC methods exposed from your application, once connected to pm2.io will be displayed and actionable from a web interface.
