1、thinkphp原来的Response设置header方式不管用了,为什么正常开发的时候却又好用?
\vendor\topthink\think-worker\src\Application.php的worker接管了Response getContent解析,无论\application下如何业务逻辑处理,只要Controller return返回的Response交给worker处理即可,我们打开\vendor\topthink\think-worker\src\Application.php,看到worker方法中通过WorkerHttp对header重新处理,workerman对header只能通过WorkerHttp。
```php
use \Workerman\Connection\AsyncTcpConnection;
// 与远程连接池服务建立异步链接,ip为远程连接池服务的ip,如果是集群就是lvs的ip
$sql_connection = new AsyncTcpConnection('Text://ip:1234');
// 发送sql
$sql_connection->send("SELECT ... FROM .....");
// 异步获得sql结果
$sql_connection->onMessage = function($sql_connection, $sql_result)
{
// 这里只是打印结果
var_dump(json_decode($task_result));
};
// 执行异步链接
$sql_connection->connect();
```
```
public function worker($connection)
{
try {
ob_start();
// 重置应用的开始时间和内存占用
$this->beginTime = microtime(true);
$this->beginMem = memory_get_usage();
// 销毁当前请求对象实例
$this->delete('think\Request');
$pathinfo = ltrim(strpos($_SERVER['REQUEST_URI'], '?') ? strstr($_SERVER['REQUEST_URI'], '?', true) : $_SERVER['REQUEST_URI'], '/');
$this->request->setPathinfo($pathinfo);
if ($this->config->get('session.auto_start')) {
WorkerHttp::sessionStart();
}
// 更新请求对象实例
$this->route->setRequest($this->request);
$response = $this->run();
$response->send();
$content = ob_get_clean();
// Trace调试注入
if ($this->env->get('app_trace', $this->config->get('app_trace'))) {
$this->debug->inject($response, $content);
}
$this->httpResponseCode($response->getCode());
foreach ($response->getHeader() as $name => $val) {
// 发送头部信息
WorkerHttp::header($name . (!is_null($val) ? ':' . $val : ''));
}
$connection->send($content);
} catch (HttpException $e) {
$this->exception($connection, $e);
} catch (\Exception $e) {
$this->exception($connection, $e);
} catch (\Throwable $e) {
$this->exception($connection, $e);
}
}
```
我们按照原来thinkphp开发方式对异常进行拦截
