为社区配置Dispatcher configuring-dispatcher-for-communities

AEM Communities aem-communities

对于AEM Communities,必须配置Dispatcher以确保正常运行 社区站点. 在包含社交登录等功能时,需要额外的配置。

Dispatcher缓存 dispatcher-caching

概述 overview

AEM Communities的Dispatcher缓存让Dispatcher能够为社区站点的页面提供完全缓存版本。

目前,它仅支持匿名网站访客,例如浏览社区网站或因搜索而登陆社区页面的用户,以及索引页面的搜索引擎。 这样做的好处是,匿名用户和搜索引擎可以体验到改进的性能。

对于已登录的成员,Dispatcher会绕过缓存,将请求直接转发给发布者,以便动态生成并交付所有页面。

在配置为支持Dispatcher缓存时,会向标头添加基于TTL的“最大期限”过期时间,以确保Dispatcher缓存的页面是最新的。

要求 requirements

  • Dispatcher版本4.1.2或更高版本(请参阅 安装Dispatcher (适用于最新版本)

  • ACS AEM Commons包

    • 版本3.3.2或更高版本
    • ACS AEM Commons - Dispatcher Cache Control Header - Max Age OSGi配置

配置 configuration

OSGi配置 ACS AEM Commons - Dispatcher缓存控制标头 — 最大保留时间 设置显示在指定路径下的缓存页面的过期时间。

  • Web控制台.

  • 定位 ACS AEM Commons - Dispatcher Cache Control Header - Max Age

  • 选择“+”图标以创建连接配置。

    dispatcher

  • 筛选模式
    (必填) 社区页面的一个或多个路径。 例如:/content/sites/engage/(.*)

  • Cache-Control最长使用时间
    (必填) 添加到Cache Control标头的最长时间(以秒为单位)。 该值必须大于零(0)。

Dispatcher过滤器 dispatcher-filters

的/filter部分 dispatcher.any 文件记录于 配置对内容的访问 — /filter.

本节介绍社区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字表示应用过滤器模式的顺序的约定。 对一个请求应用了多个过滤模式时,最后一个应用的过滤模式生效。 因此,第一个过滤模式通常用于拒绝所有内容,使得以下模式用于以受控方式恢复访问。

以下示例使用的属性名称可能必须修改以适合任何特定情况 dispatcher.any 文件。

另请参阅:

NOTE
属性名称示例
显示的所有属性名称,例如 /0050/0170,应该进行调整以适合现有的 dispatcher.any 配置文件。
CAUTION
请参阅 Dispatcher 安全检查清单以了解使用 Dispatcher 限制访问时的更多注意事项。有关 AEM 安装的其他安全详细信息,另请阅读 AEM 安全检查清单

应将以下条目添加到/filter部分的末尾,尤其是在所有被拒绝的条目之后。

/6051 { /type "allow" /url "*.ttf" }

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

Dispatcher规则 dispatcher-rules

的规则部分 dispatcher.any 定义应根据请求的URL缓存哪些响应。 对于社区,规则部分用于定义绝不应缓存的内容。

# Never cache the client-side .social.json calls
/0001 { /type "deny" /url "*.social.json*" }

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

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

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

疑难解答 troubleshooting

问题的一个主要来源是在插入过滤器规则时没有注意对早期规则的影响,尤其是在添加拒绝访问的规则时。

第一个过滤器模式通常用于拒绝所有内容,以便后续过滤器以可控方式恢复访问。 对一个请求应用了多个筛选器时,最后一个应用的筛选器是生效的筛选器。

以下是示例 dispatcher.any 包含Communities /filters和/rules的文件。

# Each farm configures a set of load balanced renders (that is, 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 matching 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 filter section defines the requests that should be handled by the dispatcher.
    #
    # Entries can be either specified using urls, or elements of the request line:

    #
    #   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, for example,:
    #
    #     /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.
