查看 POP3/SMTP 协议的时候想尝试一下自己写一个操作类,核心没啥,就是使用 fsockopen ,然后写入/接收数据,只实现了最核心的部分功能,当作是学习 Socket 操作的练手。其中参考了 RFC 2449和一个国外的简单Web邮件系统 Uebimiau 的部分代码,不过绝对没有抄他滴,HOHO,绝对原创。

本程序是利用3.x的Firefox浏览器可以读取本地文件的特性,实现通过xmlHttPRequest上传大文件功能,并在可以上传过程中动态显示上传进度。略加修改,并与服务器端配合,可以实现断点续传等诸多功能。
本例主要是研究FireFox的file-input节点的一些特性,其他客户端应用,如Flash、Sliverlight等,在实现客户端大文件上传时,在数据传输与服务器端存储等方面,与本例的思路基本一致。
注意:文件体积似乎有临界点,但这个临界点是多少尚未确认。建议不要用此方法上传超过100M的文件。

17 * 本程序是利用3.x的FireFox浏览器可以读取本地文件的特性
18 * 实现通过XMLHttpRequest上传大文件功能
19 * 并在可以上传过程中动态显示上传进度
20 * 略加修改,并与服务器端配合,可以实现断点续传等诸多功能
21 * 本例主要是研究FireFox的file-input节点的一些特性
22 * 其他客户端应用,如Flash、Sliverlight等,在实现客户端大文件上传时
23 * 在数据传输与服务器端存储等方面,与本例的思路基本一致
24 * 注意:文件体积似乎有个临界点,但这个临界点是多少尚未确认。建议不要用此方法上传超过100M的文件。
