未使用GCM接收推送通知(Not receiving push notification using GCM)

 我正在使用GCM实现推送通知。我成功获得令牌和实例ID，服务器也在发送通知时返回成功，但我无法在手机上显示通知。 请帮忙！！！ 
 

 以下是我的代码

最满意答案

 我跑了： 
 

use strict;
use warnings;

my @Array1=qw/A B C D E/;
my @Array2=qw/L B C F E/;

foreach my $var (@Array1){
       $\=$/;
       print "Letter $var";
        foreach my $var2 (@Array2){
        if($var2 eq $var) {
            print "They are equal";
        } else {
            next;
        }
    }
}

 

 而且我知道了 
 

Letter A
Letter B
They are equal
Letter C
They are equal
Letter D
Letter E
They are equal


I've run it:
 

use strict;
use warnings;

my @Array1=qw/A B C D E/;
my @Array2=qw/L B C F E/;

foreach my $var (@Array1){
       $\=$/;
       print "Letter $var";
        foreach my $var2 (@Array2){
        if($var2 eq $var) {
            print "They are equal";
        } else {
            next;
        }
    }
}

 

and I've got it
 

Letter A
Letter B
They are equal
Letter C
They are equal
Letter D
Letter E
They are equal
