服务端

在process目录下新建自定义进程 PushProcess.php

代码语言：javascript复制
<?php
/**
 * @desc PushProcess
 * @author Tinywan(ShaoBo Wan)
 * @email 756684177@qq.com
 * @date 2024/1/12 9:17
 */

declare(strict_types=1);

namespace process;


use WorkermanTimer;

class PushProcess
{
    public function onWorkerStart()
    {
        Timer::add(1, function(){
            $api = new WebmanPushApi(
                config('plugin.webman.push.app.api'),
                config('plugin.webman.push.app.app_key'),
                config('plugin.webman.push.app.app_secret')
            );
            $api->trigger(['price-btcusd'], 'new-price', [
                'value' => rand(0, 5000)
            ]);
        });
    }
}

在config/process.php中添加如下配置

代码语言：javascript复制
// push
'push_chart'  => [
    'handler'  => processPushProcess::class
],

客户端

1、在webman2024/app/controller新建chartsPush方法

代码语言：javascript复制
public function push(Request $request)
{
    return view('index/charts_push');
}

2、在webman2024/app/view/index目录新建charts_push.html

代码语言：javascript复制

  google.charts.load("current", { packages: ["corechart"] });
  google.charts.setOnLoadCallback(() => {
    // Instead of hard-coding the initial table data,
    // you could fetch it from your server.
    const dataTable = google.visualization.arrayToDataTable([
      ["Year", "Price"],
      [2013, 400],
      [2014, 460],
    ]);
    const chart = new google.visualization.AreaChart(
            document.getElementById("chart_div")
    );
    const options = {
      title: "1 BTC in USD",
      hAxis: { title: "Year 2022 (Tinywan)", titleTextStyle: { color: "#333" } },
      vAxis: { minValue: 0 },
      animation: { duration: 100, easing: "out" },
    };
    chart.draw(dataTable, options);
    let year = 2024;

    // (1) 创建实例
    const pusher = new Push({
      url: 'ws://127.0.0.1:8788', // websocket地址
      app_key: '216e96a3506044bfd2b8b6eb7c492d32'
    });

    const channel = pusher.subscribe("price-btcusd");
    channel.on('new-price', function(data) {
      const row = [year  , data.value];
      dataTable.addRow(row);
      chart.draw(dataTable, options);
    });
  });
</script>
</body>
</html>
