Perl 对象是函数的第一个参数

 #目前只能用于群回复
    my $client = Weixin::Client->new(debug=>0);  创建一个对象，

     return $self;  返回对象


     sub add_friend{
    my $self = shift;
    my $friend = shift;
    my $f = first {$friend->{Id} eq $_->{Id}} @{$self->{_data}{friend}};    
    if(defined $f){
        $f = $friend;
} 
    else{
        push @{$self->{_data}{friend}},$friend;
}
}
sub del_friend{
    my $self = shift;
    my $id = shift;

    函数的第一个参数就是对象




    my $client = Weixin::Client->new(debug=>0); 

    调用new方法后返回一个对象,用作其他方法的第一个参数
