我有一个 Javascript/Ajax 文件上传器（https://github.com/Valums-File-Uploader/file-uploader），它可以在 latin-1 编码的网页上正常工作。现在我尝试在 UTF-8 环境中使用它，但它失败了。
这是我的代码（我只需要变量中的图像，保存在其他地方完成）：
sub parseMultiPart{
use CGI;
use IO::Handle;
use Encode;
$CGITempFile::TMPDIRECTORY = $ENV{ADFRAME_TMP_FILES};
$CGI::POST_MAX=1024 * 1024 * 5;
#$CGI::PARAM_UTF8=1;
my $cgi = new CGI;
foreach $key ($cgi ->param) {
my $upload = $cgi->upload($key);
if(defined $upload) {
# THIS DOES NOTHING SINCE UPLOAD IS NOT DEFINED
my $file=$cgi->param($key);
binmode $upload;
my $data;
while (read($upload_file, $upload, 1024)) {
$main::in{$key} .= $data;
}
$main::inct{$key} = $cgi->uploadInfo($file)->{'Content-Type'};
}
else {
my @val = $cgi->param($key);
# THIS DOES THE WORK
if (scalar @val == 1) {
$main::in{$key} = $val[0];
}
# /
else {
$main::in{$key} = \@val; # save value as an array ref
}
}
}
}
1;
然后在下一步中：
if (open (HI, ">$storePath/$filename")) {
binmode HI;
print HI $data;
close(HI);
}
这里有几个问题：
CGI->upload()不认为这是上传。我现在才注意到，因为它从来没有引起任何问题。- 使用
multipart/formdata会导致服务器中止并且不发送任何内容。 - 像这样使用它，我收到一条
Wide character in print消息。 - 如果我
encode $val[0]不会收到消息，则生成的文件仍然已损坏。 - 如果
binmode $val[0]我得到wide characters in print
有人可以帮忙吗？？
谢谢，
托马斯
