我正在尝试使用Yii导出CSV到浏览器，CSV一直被Yii日志消息填充。
header('Content-Description: File Transfer');
header('Content-Type: application/csv');
header('Content-disposition: attachment; filename=enrollment_course.csv');
$enrollment = Reports::getEnrollment($courseId);
$separator=",";
foreach ($enrollment as $users)
{
$tmp = array(
$users->userid,
$users->firstname,
$users->lastname,
);
echo join($separator, $tmp)."'n";
}
Yii::app()->end();
知道为什么这不能正常工作吗?
是的，我实际上写了一个扩展:http://www.yiiframework.com/extension/csvexport/
基本上相当于调用exit，看一下示例的最后几行:
// options for file, changing delimeter and enclosure
$content = $csv->toCSV('../myfilename.csv', "'t", "'");
Yii::app()->getRequest()->sendFile($filename, $content, "text/csv", false);
// call exit instead of letting sendFile do it, because if you are using
// CWebLogRoute, the onEndRequest event will fire and output your log and not csv file :(
exit();
我建议在输出完所有内容后终止脚本。这样可以防止向输出中添加任何内容。一个简单的"die"就可以了。
您可以在控制器中使用以下代码来禁用所有操作的浏览器记录:
protected function beforeAction($action)
{
foreach (Yii::app()->log->routes as $route)
{
if ($route instanceof CWebLogRoute)
{
$route->enabled = false;
}
}
return true;
}
