为社区配置Dispatcher

AEM Communities

对AEM Communities来说,必须配置调度程序以确保社区站点正常 运行 。 包括社区启用和社交登录等功能时,需要进行其他配置。
了解特定部署和站点设计的必要条件
另请参阅主 Dispatcher文档

调度程序缓存

概述

针对AEM Communities的调度程序缓存是调度程序提供社区站点页面完全缓存版本的功能。
目前,它仅受匿名网站访客(如浏览社区站点或登录社区页面作为搜索结果的用户)以及为页面编制索引的搜索引擎支持。 优势在于,匿名用户和搜索引擎将体验到改进的性能。
对于已登录的成员,调度程序会绕过缓存,将请求直接转发给发布者,这样所有页面都会动态生成并传送。
当配置为支持调度程序缓存时,将在标头中添加一个基于TTL的“最大页面”过期,以确保调度程序缓存页面是最新的。

要求

配置

OSGi配置 ACS AEM Commons - Dispatcher Cache Control Header - Max Age (OSGi配置ACS共享资源——调度程序缓存控制标头- Max Age)设置在指定路径下显示的缓存页面的过期时间。
  • 从Web控 制台
  • 定位 ACS AEM Commons - Dispatcher Cache Control Header - Max Age
  • 选择“+”图标以创建新连接配置
  • 滤镜图案
    (必需) “社区页面”的一个或多个路径。 For example, /content/sites/engage/(.*) .
  • 高速缓存控制最大时间
    (必需 )要添加到“Cache Control(缓存控制)”标头的最大时间(以秒为单位)。 值必须大于零(0)。

调度程序客户端头

在的/clientheaders部分 dispatcher.any 中,如果列出一组特定的标题,则必须包含这些标题, "CSRF-Token" 以使“启用” 功能正常工作

调度程序过滤器

文件的/filter部分在配 dispatcher.any 置对内容的 访问- /filter中有介绍
本节介绍Communities功能正常运行可能需要的条目。
过滤器属性名称遵循使用四位数来指示应用过滤器模式的顺序的惯例。 当多个过滤器模式应用于请求时,应用的最后一个过滤模式将有效。 因此,通常使用第一过滤器模式来拒绝所有内容,以使以下模式以受控方式恢复访问。
以下示例使用的属性名称可能需要进行修改以适合任何特定调度程序。any文件。
另请参阅:
属性名称示例
显示的所有属性名称( 如/0050 和/0170 )都应调整为适合现有的调度程序。任何配置文件。
应将以下条目添加到/filter部分的末尾,尤其是所有拒绝条目之后。
# design and template assets
/0050 { /type "allow" /glob "GET /etc/designs/*" }

# collected JS/CSS from the components and design
/0051 { /type "allow" /glob "GET /etc/clientlibs/*" }

/0171 { /type "allow" /glob "POST /content/sites/*/resources/en/*" }
/0172 { /type "allow" /glob "GET /content/communities/enablement/reports/*" }
/0173 { /type "allow" /glob "GET /content/sites/*" }

/5001 { /type "allow" /glob "GET /libs/granite/csrf/token.json *"}
# Allow SCF User Model to bootstrap as it depends on the granite user
/5002 { /type "allow" /glob "GET /libs/granite/security/currentuser.json*" }

# Allow Communities Site Logout button work
/5003 { /type "allow" /glob "GET /system/sling/logout.html*" }

# Allow i18n to load correctly
/5004 { /type "allow" /glob "GET /libs/cq/i18n/dict.en.json *" }

/6051 { /type "allow" /glob "GET *.ttf *" }

# Enable CQ Security checkpoint for component guide.
/7001 { /type "allow" /glob "GET /libs/cq/security/userinfo.json?cq_ck=*"

调度程序规则

的规则部分定 dispatcher.any 义应根据所请求的URL缓存哪些响应。 对于“社区”,规则部分用于定义不应缓存的内容。
# Never cache the client-side .social.json calls
/0001 { /type "deny" /glob "*.social.json*" }

# Never cache the user-specific .json requests
/0002 { /type "deny" /glob "/libs/granite/csrf/token.json*" }
/0003 { /type "deny" /glob "/libs/granite/security/currentuser.json*" }
/0004 { /type "deny" /glob "/libs/granite/security/userinfo.json*" }

# Never cache the private community groups pages in case - add your own deny rules in there
/0005 { /type "deny" /glob "/content/*/groups/*" }

# Never cache the assignments page in case the Enablement feature is in use - add your own deny rules in there
/0006 { /type "deny" /glob "/content/*/assignments/*" }

# Never cache user generated content
/0208 { /type "deny" /glob "/content/usergenerated/*" }

疑难解答

一个主要问题是插入筛选器规则时不注意对早期规则的影响,尤其是添加规则以拒绝访问时。
第一个过滤器模式通常用于拒绝所有内容,以便以受控方式过滤器恢复访问。 当多个过滤器应用到请求时,应用的最后一个过滤器是有效的过滤器。

示例调度程序。any

以下是包含 dispatcher.any Communities /过滤器和/rules的示例文件。
# Each farm configures a set of load balanced renders (i.e. remote servers)
/farms
  {
  # First farm entry
  /website
    {
    # Request headers that should be forwarded to the remote server.
    /clientheaders
      {
      # Forward all request headers that are end-to-end. If you want
      # to forward a specific set of headers, you'll have to list
      # them here.
      "*"
      }

    # Hostname globbing for farm selection (virtual domain addressing)
    /virtualhosts
      {
      # Entries will be compared against the "Host" request header
      # and an optional request URL prefix.
      #
      # Examples:
      #
      #   www.company.com
      #   intranet.*
      #   myhost:8888/mysite
      "*"
      }

    # The load will be balanced among these render instances
    /renders
      {
      /rend01
        {
        # Hostname or IP of the render
        /hostname "127.0.0.1"

        # Connect timeout in milliseconds, 0 to wait indefinitely
        # /timeout "0"
        }
      }

    # The filter section defines the requests that should be handled by the dispatcher.
    #
    # Entries can be either specified using globs, or elements of the request line:
    #
    # (1) globs will be compared against the entire request line, e.g.:
    #
    #     /0001 { /type "deny" /glob "* /index.html *" }
    #
    #   matches request "GET /index.html HTTP/1.1" but not "GET /index.html?a=b HTTP/1.1".
    #
    # (2) method/url/query/protocol will be compared againts the respective elements of
    #   the request line, e.g.:
    #
    #     /0001 { /type "deny" /method "GET" /url "/index.html" }
    #
    #   matches both "GET /index.html" and "GET /index.html?a=b HTTP/1.1".
    #
    # Note: specifying elements of the request line is the preferred method.
