1. rgw的代码做了限制:
/* Static Web Site of Swift API. */
#define RGW_ATTR_WEB_INDEX RGW_ATTR_META_PREFIX "web-index"
#define RGW_ATTR_WEB_ERROR RGW_ATTR_META_PREFIX "web-error"
#define RGW_ATTR_WEB_LISTINGS RGW_ATTR_META_PREFIX "web-listings"
#define RGW_ATTR_WEB_LIST_CSS RGW_ATTR_META_PREFIX "web-listings-css"
#define RGW_ATTR_SUBDIR_MARKER RGW_ATTR_META_PREFIX "web-directory-type"
2. 所以,不应该包含的字段有, 且区分大小写:
/* Static Web Site of Swift API. */
"web-index"
"web-error"
"web-listings"
"web-listings-css"
"web-directory-type"
