Dispatcher 是 Adobe Experience manager 的快取和/或負載平衡工具。
以下頁面提供為AEM Screens專案設定分派程式的准則。
如果調度程式可用,則可以通過在調度程式規則中進行過濾來阻止與註冊servlet的連接。
如果沒有調度程式,請禁用OSGi元件清單中的註冊servlet。
在您為AEM Screens專案設定分派程式之前,您必須具備Dispatcher的先前知識。
有關詳細資訊,請參閱配置Dispatcher。
請依照下列步驟,為AEM Screens專案設定分派程式。
如果要將多個發佈實例與調度程式一起使用,則必須更新dispatcher.any
檔案。
/stickyConnections {
/paths
{
"/content/screens"
"/home/users/screens"
"/libs/granite/csrf/token.json"
}
}
將下列內容新增至/clientheaders
區段:
X-Requested-With
X-SET-HEARTBEAT
X-REQUEST-COMMAND
若要設定「畫面」篩選,請將下列項目新增至/filter。
## AEM Screens Filters
## # Login, Ping and Device Configurations
/0200 { /type "allow" /method "POST" /url "/libs/granite/core/content/login.validate/j_security_check" }
/0201 { /type "allow" /method "GET" /url "/libs/granite/csrf/token.json" }

/0222 { /type "allow" /method '(GET|HEAD)' /url '/var/contentsync/content/screens/.+/jcr:content/.+/offline-config_.*\.[0-9]+\.zip' }
停用/content/screens path的Dispatcher caching。
畫面播放器使用已驗證的作業,因此分派器不會快取任何畫面播放器對channels/assets
的要求。
若要啟用資產的快取,以便從分派器快取中提供資產,您必須:
/cache
節中添加/allowAuthorization 1
/cache
的/rules
區段/0000
{
/glob "*"
/type "allow"
}
/0001
{
# Disable Dispatcher Cache for Screens channels
/glob "/content/screens/*.html"
/type "deny"
}
/0002
{
# Disable Dispatcher Cache for Screens offline manifests
/glob "/content/screens/*.json"
/type "deny"
}
/0003
{ # Disable Dispatcher Cache for Screens devices json
/glob "/home/users/screens/*.json"
/type "deny"
}
