介绍

hyperf框架的链路追踪组件，基于官方包改造完成，要求框架版本^2.0，原来的官方包的tag是固定的，并不实用，代码质量堪忧，这个包在原有的基础上做了修改

特点

• 支持自定义tag，通过闭包完全自定义
• 删除了冗余文件，增加代码可读性

使用

• 安装组件

composer require hyperf/tracer

• 安装依赖

如果不是使用的是jaeger作为链路，可以忽略这一步

composer require jonahgeorge/jaeger-client-php

• 发布配置

php bin/hyperf.php vendor:publish sett/hyperf-tracer

• 添加配置

在config/autoload/opentracing.php文件中添加

• 添加中间件

在config/autoload/middlewares.php文件中添加

return [
    'http' => [
        \Sett\Tracer\Middleware\TraceMiddleware::class,
],
];
