我需要一些指导与以下Perl代码.当我离开没有严格的“参考”时,子工程正常.但是如果没有严格的’refs’被删除,那么我会收到错误信息：
Can't use string ("A") as a symbol ref while "strict refs" in use at test.pl
它在下面标记为“Here”的行中死亡.该子需要打开(写入>)所有来自A..Z的文件,并且根据READ文件(LOG)的正则表达式,输出将被写入对应的文件输出.
use strict;
use Text::CSV_XS;
no strict 'refs';
...
...
sub file_split {
my ( $i,$fh,@FH );
my ( $file ) = @_;
my ( @alpha) = ("A".."Z");
for ( @alpha) {
$fh = $_ ;
open ( $fh,">","$_-$file" ) || die $!; <--------- HERE
push @FH,$fh;
}
my $csv = Text::CSV_XS->new( { binary => 1,allow_whitespace => 1,allow_loose_escapes => 1,allow_loose_quotes =>1,escape_char => undef,sep_char => ',',auto_diag=> 1
} );
open( LOG,"<",$file ) || die $!;
while ( my $row = $csv->getline( *LOG ) ) {
if ( $row->[0] =~ /^(\w)/ ) {
print $1 <--------- HERE
"$row->[0]".",".
"$row->[1]" .",".
"$row->[2]" .",".
"$row->[3]" .",".
"$row->[4]".",".
"$row->[5]"."\n";
} else {
print "Record skipped... --> $row->[0] <-- ... please verify \n";
}
}
}
解决方法
不要分配$fh = $_它没有任何有用的东西.
@FH应该是％FH,而不是push try：
$FH{ $_ } = $fh
将$1替换为$FH {$1}.
