【问题描述】:
我编写了一个测试脚本来执行某些功能。脚本按预期工作。目前,运行脚本所需的参数是使用Getopt::Long从命令行传递的。我想将命令行参数移动到 json 文件中。端点 ip 仍将作为命令行参数传递。
我希望端点 ip 充当密钥。例如,如果端点是 1.1.1.1,我想获取下面提到的 json 配置文件中端点 id 1.1.1.1 下列出的 client_ip、client_interface_ip、originip、....、端口。我该怎么做?
脚本的当前版本:
use Getopt::Long;
my ($self) = @_;
GetOptions (
"endpoint|e=s" => \$self->{'endpoint'},
"aggregator|a=s" => \$self->{'aggregator'},
"port|pt=s" => \$self->{'port'},
"client|c=s" => \$self->{'client'},
"client_interface|ci=s" => \$self->{'client_interface'},
"origin|o=s" => \$self->{'origin'},
"origin_interface|oi=s" => \$self->{'origin_interface'},
"interfacename|ot=s" => \$self->{'i1'},
"interfacename2|it=s" => \$self->{'i2'},
) || $self->abort( "Invalid command line options.
Valid options are endpoint,aggregator,port,client,client_interface,
origin,origin_interface,outertunnel,innertunnel,");
#Terminate the script execution if the reqd args are not passed
my @required_args = qw(endpoint aggregator port client client_interface origin origin_interface
);
for my $command_line_arguments (@required_args) {
unless ($self->{$command_line_arguments}) {
$self->abort('missing required argument ' . $command_line_arguments);
}
}
$self->{'tObj'} = QA::crypto::tunnels->new
('host'=> $self->{'endpoint'})
or $self->abort('[Could not create a QA::Crypto::tunnels object.]');
参数的json文件:
{
"Endpoints": [{
"endpoint": "1.1.1.1",
"client_ip": "3.4.5.6",
"client_interface_ip": "10.11.12.14",
"origin": "a.a.a.a",
"origin_interface": "15.16.17.18",
"interfacename": "name",
"interfacename2": "name1",
"sl": 19,
"port": 362
}, {
"endpoint": "2.2.2.2",
"client_ip": "19.20.21.22",
"client_interface_ip": "23.24.25.26",
"origin": "1.2.3.4",
"origin_interface": "5.6.7.8",
"interfacename": "interface name",
"interfacename2": "interfacename_2",
"sl": 19,
"port": 366
}]
}
#!/usr/bin/perl
