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
代码语言：javascript复制 1 try {
2 $this->kernal->process($this->request, $this->response);
3 } catch (Throwable $throwable) {
4 //获取header
5 $accept = $this->request->header["accept"];
6
7 if (strpos($accept, "json")) {
8 $data["file"] = $throwable->getFile();
9 $data["codeLine"] = $throwable->getLine();
10 $data["error"] = $throwable->getMessage();
11 $this->response->setHeader("Content-Type", "application/json");
12 $this->response->send(json_encode($data));
13 } else {
14 $str = <<<EOL
15 <h1>Error Message: {$throwable->getMessage()}</h1>
16 <h2>Error File: {$throwable->getFile()}</h2>
17 <h2>Error Line: {$throwable->getLine()}</h2>
18 <h3>Error Traces:</h3>
19 EOL;
20 foreach ($throwable->getTrace() as $trace){
21 $str .= "<h3>{$trace["file"]}:{$trace["line"]}</h3>";
22 }
23 $this->response->send($str);
24 }
25
26 }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)
