读缓存的静态文件信息
- <file act=info>WEB-INF/cache/page_test.html</file>
判断静态文件是否存在
- <if x="@{file:exists}"else=0>
- <call>page</call>
- <callxcallxcallxcallx=true>cache</call>
- </if>
存在就调用cache，不存在则调用page
- <call>page</call>
- <call x=true>cache</call>
可调用标签cache，读缓存文件
- <chtml onlycallid=cache>
- <file act=read method=str name=page>WEB-INF/cache/page_test.html</file>
- </chtml>
可调用标签page
- <chtml id=page file="@{sys:curPath}file_page.html" save="WEB-INF/cache/page_test.html" onlycall />
引入动态网页文件@{sys:curPath}file_page.html，并保存为WEB-INF/cache/page_test.html文件
显示缓存内容
@{file:page}
完整代码
- <html>
- <chtml>
- <file act=info>WEB-INF/cache/page_test.html</file>
- <if x="@{file:exists}" else=0>
- <call>page</call>
- <call x=true>cache</call>
- </if>
- </chtml>
- <chtml id=page file="@{sys:curPath}file_page.html" save="WEB-INF/cache/page_test.html" onlycall />
- <chtml onlycall id=cache>
- <file act=read method=str name=page>WEB-INF/cache/page_test.html</file>
- </chtml>@{file:page}
- </html>
