linux用busybox里边的httpd可以加一个简单脚本实现上传,可以说是最小巧的http服务器了。windows里边可以用hfs,但是感觉还是有时候反应慢,显臃肿。后来发现一个更小的http服务器EasyWebSever,60多kb,支持cgi,php之类的。当然也可以用python,nodejs做简单的绿色服务器,但还是麻烦些。EasyWebSever实现上传可以加php,但是下载php就几十兆,也可以加python,nodejs,都是需要的东西太大。
所以我想用js脚本去实现,解释程序windows自带,用个1k的脚本就行了。鼓捣半天发现js不支持二进制,最后没办法,改成了autoit3脚本。脚本参考的httpd_post_upload.cgi « networking - busybox - BusyBox: The Swiss Army Knife of Embedded Linux
EasyWebSever服务器设置映射--扩展名au3,执行程序“D:PCAPPSautoit3AutoIt3.exe d:tmp1.au3”,就是用1.au3当解释程序。用autoit3.exe当解释程序的话,因为服务器调用时不直接传递参数 ,而是靠环境变量传递,所以不能用。
index.htm的代码:
---------------------------------------------------------------------------------------------------------------------------------
1.au3的代码:
ConsoleWrite(Binary("0x0a0d0a0d"))
$script_name=EnvGet("script_NAME")
$oexec=run("D:PCAPPSautoit3autoit3 d:tmp" & $script_name,@WorkingDir, @SW_HIDE, 7)
$aa=Binary("")
while 1
$cc = ConsoleRead(0,1)
If @error Then ExitLoop
$aa=$aa & $cc
WEnd
StdinWrite($oexec,BinaryLen($aa) & chr(13))
StdinWrite($oexec,$aa )
$bb=Binary("")
while 1
$cc = StdoutRead($oexec,0,1)
If @error Then ExitLoop
$bb=$bb & $cc
WEnd
ConsoleWrite($bb)
--------------------------------------------------------------------------------------------------------------------------------
2.au3的代码:
$aa=Binary("")
$count=0
$countok=0
$ii=0
while 1
$cc = ConsoleRead(0,1)
If @error Then ExitLoop
if @extended >0 then
$aa=$aa & $cc
$count=$count+@extended
if $count>20 then
if $countok=0 then
$tt=BinaryMid($aa,1,20)
$ttt=BinaryToString($tt)
$ii=StringInStr($ttt,chr(13))
$ccc=StringLeft($ttt,$ii)
$countok=1
endif
if $count>=$ccc+$ii Then ExitLoop
endif
endif
WEnd
for $i=$ii+1 to 2000
if BinaryMid($aa,$i,1)= chr(13) Then ExitLoop
next
$fengexian=BinaryMid($aa,$ii+1,$i-$ii-1)
for $iii=$i+1 to 2000
if BinaryMid($aa,$iii,2)= chr(10) & chr(13) Then ExitLoop
next
$ff=FileOpen("tmp",2)
FileWrite($ff,BinaryMid($aa,$iii+3,BinaryLen($aa)-$iii-3-BinaryLen($fengexian)-5))
FileClose($ff)
$dd=BinaryMid($aa,BinaryLen($aa)-BinaryLen($fengexian)-3,BinaryLen($fengexian))
if $fengexian = $dd then
ConsoleWrite("ok")
else
ConsoleWrite("err")
endif
-------------------------------------------------------------------------------------------------------------------------
最后我把js的代码也列出来,1.js:
var WshShell = Wscript.CreateObject("Wscript.Shell");
var WshSysEnv = WshShell.Environment("PROCESS");
script_name=WshSysEnv("script_NAME")
oexec=WshShell.exec("cscript /nologo d:\tmp\"+script_name)
aa=Wscript.StdIn.readall()
Wscript.StdOut.Write("rn")
Wscript.StdOut.Write("rn")
oexec.StdIn.Write(aa.length+"n")
oexec.StdIn.Write(aa );
Wscript.StdOut.Write(oexec.StdOut.readall())
------------------------------------------------------------------------------------------------------------------------------
2.js
count=Wscript.StdIn.readLine() //如果不用count计数,程序会一直阻塞,因为不能确定管道的终点
fengexian=Wscript.StdIn.readLine()
count-=fengexian.length+2 //如果浏览器发送的换行是一个字符,程序会出问题
while (true){
bb=Wscript.StdIn.readLine()
count-=bb.length+2
if (bb=="rn" || bb=="")break;
}
aa=Wscript.StdIn.read(count-fengexian.length-6)
fso = new ActiveXObject("scripting.FileSystemObject")
f = fso.CreateTextFile("d:\tmp\tmp", true)
f.Write(aa);
f.Close();
Wscript.StdIn.read(2)
cc=Wscript.StdIn.read(fengexian.length)
if(fengexian==cc)Wscript.echo ("ok")
else Wscript.echo ("err")
