PHP框架开发——swoole框架异常处理

在swoole框架中使用 set_error_handler 和 set_exception_handler 根本不起作用，原因应该是被swoole扩展从底层劫持啦。当需要整体捕获运行中的错误和异常的时候，只能将绑定在onRequest的函数try.. catche 起来

另外 在php7中 Error和Exception都实现了 Throwable 接口，所以如何想要同时捕获 这两种错误应该 捕获Throwable

try {
            $this->kernal->process($this->request, $this->response);
} catch (Throwable $throwable) {
            //获取header
            $accept = $this->request->header["accept"];

            if (strpos($accept, "json")) {
                $data["file"] = $throwable->getFile();
                $data["codeLine"] = $throwable->getLine();
                $data["error"] = $throwable->getMessage();
                $this->response->setHeader("Content-Type", "application/json");
                $this->response->send(json_encode($data));
            } else {
                $str = <<<EOL
<h1>Error Message: {$throwable->getMessage()}</h1>       
<h2>Error File: {$throwable->getFile()}</h2>    
<h2>Error Line: {$throwable->getLine()}</h2>
<h3>Error Traces:</h3>
EOL;
                foreach ($throwable->getTrace() as $trace){
                    $str .= "<h3>{$trace["file"]}:{$trace["line"]}</h3>";
                }
                $this->response->send($str);
            }

}

接口访问出错时，以json格式显示

 页面访问时以web形式显示，(请忽略这个丑陋的样式)
