1.首要的就是去掉那个index of字样，
实在是太丑了。可是我无论怎么更换关键字，都找不到答案，于是硬着头皮看官方英文文档
终于在一堆如虫子的字样中找到这样一句话
- SuppressHTMLPreamble
- If the directory actually contains a file specified by the
HeaderNamedirective, the module usually includes the contents of the file after a standard HTML preamble (<html>,<head>, et cetera). TheSuppressHTMLPreambleoption disables this behaviour, causing the module to start the display with the header file contents. The header file must contain appropriate HTML instructions in this case. If there is no header file, the preamble is generated as usual.
2.其他美化选项（./htaccess）
