让你同时上传 1000 个文件

Jun 13, 2016 am 10:21 AM
javascript perl php window upload indivual document test environment Knowledge

预备知识:Javascript, PHP(少量)/Perl(少量)!
测试环境:Windows2000 + IIS5 + PHP (Win98 + PWS + PHP3 失败,估计是配置出了问题)
目录结构:
/wwwroot/cgi-bin/fileup.php (文件接收)
/wwwroot/www/test/phpfileup.htm (文件提交)
/wwwroot/www/test/tmp/ (默认保存目录)

前言:文件上传,简单又麻烦。下面是上传文件的提交页面,利用该页面你不仅可以生成 1000 个上传文件框(实际是任意多个 0~n ),而且可分别指出它们的保存路径。
提交页面的文件输入框为命名为: file0,file1,...file100,...fileN
提交页面的文件路径框为命名为: path0,path1,...path100,...pathN
由于页面的生成非常简单,所以就不在此多解释了,用 javascript 定义了两个函数,check() 用于提交页面,create()用于生成文件上传框。如果你有什么更好的建议或有什么疑问请 Email: gearsoft@netease.com

phpfileup.htm
--------------------------------------------------------





请输入要上传文件的数量:












文件提交页面既已生成,下面任务就很明确了:将提交的文件内容保存到服务器上。

下面我们用两种方法来实现这个功能:

1. 用 PHP 来保存:
我们先定义一个文件保存函数 fup() 它有两个参数:
$filename: 文件内容
$fname: 文件名(包含路径)
剩下的就是写一个循环将文件依次写入服务器。这里要简单说明一下:
PHP 对于上传文件的处理是这样的:如果提交的文件框我为 file0, 那么提交给 PHP 的文件内容保存在变量 $file0 中,而文件名则保存在 $file0_name 中。这样在这个循环中我要做的就是将提交页面提交的内容分解出来,实现过程请看下面的代码。

fileup.php
----------------------------------------------------------------------

function fup($filename,$fname)
{ If($filename != "none") {
copy($filename,$fname);
unlink($filename);
}
}

for($i=0;$i{
$ffnn="file".$i;
$ffnnname=$ffnn."_name";
$ffpath="path".$i;

//print $$ffnn;
print $$ffnnname;
print "
";

fup($$ffnn,$$ffpath.$$ffnnname); //"../www/test/tmp/"
}
?>
----------------------------------------------------------------------

2. 用 PERL 来保存:
它们实现的原理完全一样,在此不多说,请看代码:

fileup.cgi(fileup.pl)
----------------------------------------------------------------------
#!/usr/bin/perl

use CGI qw/:standard/;

if ($ENV{CONTENT_TYPE} !~ /multipart/form-data/) {
print "Cache-Control: no-cachenPragma: no-cachen" .
"Content-Type: text/htmlnn" .
"

Your web browser cannot upload files. Sorry.";
exit 0;
}


$cntfile=param(cnt);
print header;
print start_html;
#print "Receiving Please wait....";

&g_head;

#$writed = ../www/test/tmp/;

for ($i=0;$i$paramfile = file.$i;
$parampath=path.$i;

$writed=param($parampath);

&upfile;
&g_body;
}

&g_bott;

#

sub upfile
{
$maxdata = 512000;
# $writed = ../www/test/tmp/;


$strRFname=reverse $xfile;
$intIndex=index($strRFname,);
$strNetFname=substr($strRFname,0,$intIndex);
$strNetFname=scalar reverse $strNetFname;


if((stat $xfile)[7]>$maxdata){
print "Status: 411 Size Not Allowedn" .
"Content-Type: text/htmlnAllow: POSTnn" .
"

411 411 Size Not Allowed

You got big problem. Try again.

n";
exit 0;
}


binmode $xfile;
use File::Copy;
copy($xfile,$writed.$strNetFname);
}

sub g_head{
print

;
print ;
print ;
print ;
print ;
print ;
print ;
}

sub g_body{
print

;
print ;
print ;
print ;
print ;
}

sub g_bott{
print

文件上传结果(Upload Result)
SourceFile:DestFile:Upload
.$xfile ..$writed.$strNetFname.OK!
;
}
