firefox（「$ linkurl」）;問題

Question

誰能告訴我爲什麼firefox不打開與下面的Net :: HTTPServer線添加？

#!/usr/bin/perl 
# v5.10.1/linux 
use strict; 
use warnings; 
use Shell; 
use Net::HTTPServer; 


############ section ############### 
my $server = new Net::HTTPServer(
           port=>5000, 
           docroot=>"/home/frank/Perl/perl_info_pages", 
           log => "/home/frank/Perl/perl_info_pages/access.log", 

           chroot => 0,  #  - Run the server behind a virtual chroot(). 
           # Since only root can actually call chroot, 
           # a URL munger is provided that will not 
           # allow URLs to go beyond the document root 
           # if this is specified. 
           # (Default: 1)/true ??? 

           # allow only for localhost... and user *** 
           # super server daemon control of?? 
           # cgi... 
           ); 

$server->Start(); 
$server->Process(); 
############# end of section ################### 

# can anyone tell me why these lines work(to open up firefox) with the above section commented out, but do not work when they are uncommented?? 
my $linkurl = 'http://localhost:5000'; 
firefox ("$linkurl"); 

Answer 1

作爲解釋到的HttpServer文檔中，Process()呼叫阻塞和無限期地運行服務器，因此最後兩行從來沒有達到過。

您可以做的最簡單的事情是在Start和Process之間產生Firefox進程：套接字已經被創建，並且當進程派生代碼將返回時服務器將開始運行。

Net::HTTPServer的Process方法永遠不會返回，除非您給它超時。如果要打印消息，則必須在調用Process之前執行此操作。如果你想知道服務器綁定到什麼端口，你可以在開始之後執行它。
