ASP 无组件上传

asp 无组件上传

说明:从网上收集了一部分,自己写了一部分。主要提升就是对于form的二进制数据进行了类封装,可以容易的得到form内的元素的信息。

form 二进制数据格式:

分割标志数据 + 0x0d0a

元素说明信息 + 0x0d0a0d0a

元素内容数据 + 0x0d0a

1. upload.htm

<html>

  <head><title>文件上传</title></head>

  <body>

<form enctype="multipart/form-data" action="upload.asp" method="post">

<input name="text0" type=text value="文本框"><br>

<input name="file1" type=file accept="image/*"><br>

<input name="file2" type=file accept="image/*"><br>

<input type=submit value="上传">

</form>

  </body>

</html>

2. upload.asp
