我愿随时向客户通报大清单的内容,并根据标准或定期加以更新。 然后,客户密码就能够填补地方的下降,避免长时间的下载时间。
这些清单可接近4k项,如果不进行沥滤,就会有活力地过滤这些物品,从而导致几次相当大规模的往返。
我怎么办? 我指的是,什么模式和战略适合这样做?
JSON的侵略式骑手将为此而努力,你只是将联合材料编成册,然后将其投向统一法律的结尾处,以便在修改时更新。 一项修订可能认为:
/media/js/ac.js?1234ABCD
当档案发生变化时,散射线会发生变化。
/media/js/ac.js?4321DCBA
这样一来,当客户装上该页时,你的服务器-侧代码与填满的URL连接起来,客户将在其下页负荷上得到304份未经修改的回复(假设你能够在服务器上这样做)。 如果你使用这种方法,你就应当确定档案永远不会到期,因为“到期”部分将由散列处理,即当联合文件does<>em>到期时,该散列车将改变,当事人得起304台,而不是200台。
ac.js 可能包含一个清单或其他可操作的版本,即您的汽车编码可与完成库相提并论,而你可以与任何其他共同文件变量一样查阅。
然而,实际上,大多数项目都需要这样做。 使用像超标的服务器和高压压缩机这样的东西,将使文件既小又令人惊讶地迅速负荷。 如果名单为HUGE(即数千件物品),你可能会考虑这一点。
煤炭是解决这一问题的好办法,它将跟踪变化,在作出改变之前,将 b头ever锁,从而改变该项目的URL。
你们可能考虑而不是在当地储存数据,利用 j和日本宇宙航空研究开发机构积极更新 drop名单。 可在需要时发出呼吁,下载量相当快。
只是一个想法。
这可能有助于:

如果其只是文字数据,你就能够在网络服务器上压缩,而且有不到100个项目,那么可能没有必要在客户文字中保留清单。
通常最好把你的所有数据(清单项目是数据)放在一个地方,这样你就不得不担心同步。
