【问题描述】：
我的 perl 脚本无法连接到在 localhost 端口 4444 中运行的 selenium 独立服务器。在不同的环境中会发生不同的事情。
Windows 7：脚本有时有效，有时无效。
Selenium 服务器端：正常启动。但是当我创建远程驱动程序实例时没有创建新的会话。

代码方面：注意我确实尝试了端口 4444 和其他变体。
my $browser = "firefox";
my $platform = "WINDOWS";
eval
{
$self->{seldriverarray} = new Selenium::Remote::Driver(browser_name => $browser, platform => $platform);
$self->{seldriverarray}->debug_on;
print Dumper $self->{seldriverarray}->status;
};
抛出以下内容
Use of uninitialized value in string ne at C:/Dwimperl/perl/site/lib/Selenium/Re
mote/RemoteConnection.pm line 30, <FH> line 48.
Use of uninitialized value in string eq at C:/Dwimperl/perl/site/lib/Selenium/Re
mote/RemoteConnection.pm line 35, <FH> line 48.
Selenium server did not return proper status at C:/Dwimperl/perl/site/lib/Seleni
um/Remote/Driver.pm line 232.
当我在另一个环境中运行它时会发生最奇怪的事情 Suse 企业版：
Selenium 服务器端：看到它创建了一个新会话，这意味着代码没有错误。那么，是什么阻止了代码在 Windows 中启动新会话？我无法在linux中运行脚本，因为它正在超时很长一段时间无法启动firefox。

【问题讨论】：
-
如果您查看网格控制台，您将看到集线器具有哪些功能，所以从您在 localhost:4444/grid/console 启动它的主机上看到，我怀疑您可能需要类似 VISTA 的平台

我在 Selenium RemoteConnection.pm 代码中打开了调试选项，我看到它在 LWP http 包中超时。
package LWP::Protocol::http::SocketMethods; sub sysread { my $self = shift; if (my $timeout = ${*$self}{**io_socket_timeout**}) { **die "read timeout" unless $self->can_read($timeout)**; }
