您可以在XML - RPC对象中开启调试来校验它。
You can turn on debugging in the XML-RPC object to verify this.
当一个页面被扫描时，它的校验和被计算且与该页面存储在一起。
When a page is scanned, its checksum is calculated and stored with the page.
如果该值与原始校验和不同，则本次扫描的后续搜索将抛弃这个页面(因为它更改了，不值得跟踪)。
If it's found to be different than the original checksum, the page is discarded from further search in this scan (because if it changes, it's not worthwhile to track).
