我可以创建我的目录，但我似乎不能把文件放在目录中。

#!/usr/bin/perl
use Cwd;
use CGI;
my $dir = getcwd();
print "Current Working Directory: $ dir\n";
my $photoDir = "$dir/MyPhotos";
mkdir $photoDir
        or die "Cannot mkdir $photoDir: $!"
        unless -d $photoDir;
        
        
my $query = new CGI;
my $filename = $query->param("Photo");
my $description = $query->param("description");
print "Current filename: $filename\n";
my ( $name, $path, $extension ) = fileparse ( $filename, '\..*' ); $filename = $name . $extension;
print $filename;
my $upload_filehandle = $query->upload("Photo");
open ( UPLOADFILE, ">$photoDir/$filename" )
 or die "$!"; 
binmode UPLOADFILE; 
while ( <$upload_filehandle> ) 
{ print UPLOADFILE; } 
close UPLOADFILE;

CGI堆栈跟踪显示没有错误，但日志显示没有输出

**更新：**此答案已过时，今天您将直接获得IO::File兼容句柄：

# undef may be returned if it's not a valid file handle
if ( my $io_handle = $q->upload('field_name') ) {
    open ( my $out_file,'>>','/usr/local/web/users/feedback' );
    while ( my $bytesread = $io_handle->read($buffer,1024) ) {
        print $out_file $buffer;
    }
}

原始答案：*

CGI.pm手册建议使用此路径保存上传的文件。请尝试此附加的检查和写入方法，看看是否有帮助。

$lightweight_fh  = $q->upload('field_name');
     # undef may be returned if it's not a valid file handle
     if (defined $lightweight_fh) {
       # Upgrade the handle to one compatible with IO::Handle:
       my $io_handle = $lightweight_fh->handle;
       open (OUTFILE,'>>','/usr/local/web/users/feedback');
       while ($bytesread = $io_handle->read($buffer,1024)) {
         print OUTFILE $buffer;
       }
     }
