网站的二级网页关键词,跨境经验分享,wordpress密码邮箱,网站管理后台文章排序一、ofd格式介绍 国家发布过一份关于ofd编码格式的资料#xff0c;本来我想传上去的发现资源重复了#xff0c;你们可以找找看#xff0c;没有的话留个邮箱#xff0c;我看到会发给你们的
ofd本质上其实是一个压缩文件#xff0c;咱们把他当做一个压缩包来处理就好了本来我想传上去的发现资源重复了你们可以找找看没有的话留个邮箱我看到会发给你们的
ofd本质上其实是一个压缩文件咱们把他当做一个压缩包来处理就好了思路是先解压对解压后的文件进行解析处理解压后是xml文件java有很多处理xml的类这里我推荐dom4j原因是相对来说功能全、速度快处理完后再进行压缩保存为ofd格式即可
ofd的阅读器我也有只是是公司的不方便共享了大家可以找网上在线阅读器
