执行时间长，返回500

Question

I am trying to run a function in IIS - Laravel which takes about 3mins.

I just don't know why Laravel return 500.

Although I tried add the construct below

public function __construct()
{
    set_time_limit(2000);
}

When I run this function still get 500 without any error.

public function import(Request $request) 
{
    try {
        sleep(300);
        return '123';
    } catch (\Exception $e) {
        dd($e);
    }
}

Can someone tell me how fix this error?

Answer 1

I found out the reason... It's the setting in IIS7.5 - activity timeout
