The data: URI kitchen

本文介绍了一种通过特定页面获取ContentDisposition链接中数据的方法。具体步骤包括:访问指定页面,设置类型为application/x-javascript;charset=utf-8,并启用base64选项;接着将链接显示的内容复制到主输入框内,最后点击生成按钮。
Try this page.
[url]http://software.hixie.ch/utilities/cgi/data/data[/url]
To get what's in the "Content Disposition" link up there, for example:
1) Go to that page.
2) Enter "application/x-javascript;charset=utf-8" next to "Type:".
3) Check "base64".
4) Copy and paste all of the text the "Content Disposition" link brings up into the main text input area.
5) Click Generate.
