perl上传多个文件的问题
perl上传多个文件的问题
我上传三个文件,结果只有第一个文件写入了内容,而后面两个却是空文件,大家帮我看看吧 !谢谢!
代码如下:
upload.html
<html>
<body>
<form method="POST" action="/cgi-bin/upload.cgi"
ENCTYPE="multipart/form-data">
File 1:
<input type="file" name="FILE1">
<br>
File 2:
<input type="file" name="FILE2">
<br>
File 3:
<input type="file" name="FILE3">
<br>
<input type="submit" value="Upload!">
</form>
</body>
</html>
upload.cgi
#!/usr/bin/perl
use CGI;
$upfilecount = 1;
$maxuploadcount = 3; #限制上传文件的最大数
$basedir = "/var/www/cgi-bin/"; #上传的文件存放地址
$allowall = "no"; #是否不限制文件后缀上传
@theext =(".zip",".exe",".gif"); #要限制的文件后缀名
print "Content-type: text/html\n\n";
while ($upfilecount <= $maxuploadcount) {
my $req = new CGI;
my $file = $req->param("FILE$upfilecount");
if ($file ne "") {
my $fileName = $file;
$fileName =~ s/^.*(\\|\/)//; #用正则表达式去除无用的路径名,得到文件名
my $newmain = $fileName;
my $filenotgood;
if ($allowall ne "yes") {
$extname = lc(substr($newmain,length($newmain) - 4,4)); #取后缀名
for(my $i = 0; $i < @theext; $i++){ #这段进行后缀名检测
if ($extname eq $theext[$i]){
$filenotgood = "yes";
last;
}
}
}
if ($filenotgood ne "yes") { #这段开始上传
open (OUTFILE, ">$basedir/$fileName");
#print "$fileName\n";
binmode(OUTFILE);
#务必全用二进制方式,这样就可以放心上传二进制文件了。而且文本文件也不会受干扰
while (read($file, $buffer, 1024)) {
print OUTFILE $buffer;
}
close (OUTFILE);
print "$fileName";
system("bl2seq -i $fileName -j /home/zrz/Desktop/$fileName -p blastn -o junk");
#system("rm $fileName");
$message.=$file . " 已成功上传!<br>\n";
}
else{
$message.=$file . " 文件后缀不符合要求,上传失败!<br>\n";
}
}
$upfilecount++;
}
print $message; #最后输出上传信息
