Aem 在CQ外部发布的CQ表单操作

aem

Aem 在CQ外部发布的CQ表单操作,aem,Aem,我正在帮助CQ建立一个站点，在这里我有一个要求，允许作者使用标准表单组件创建表单，这些组件将数据发布到外部系统。我发现了详细说明如何创建自定义表单操作的文档，并创建了一个forward.jsp，在这里我只是尝试将请求转发到外部系统。然而，CQ似乎想将URL解释为内部路径，并给了我一个错误。我在javadoc或文档中没有看到任何可以引导我找到我想要的东西的东西。我担心我最终可能不得不在CQ中创建一个servlet，转发到该servlet，然后在该servlet中发布到外部站点。这里有没有人有幸做了

我正在帮助CQ建立一个站点，在这里我有一个要求，允许作者使用标准表单组件创建表单，这些组件将数据发布到外部系统。我发现了详细说明如何创建自定义表单操作的文档，并创建了一个forward.jsp，在这里我只是尝试将请求转发到外部系统。然而，CQ似乎想将URL解释为内部路径，并给了我一个错误。我在javadoc或文档中没有看到任何可以引导我找到我想要的东西的东西。我担心我最终可能不得不在CQ中创建一个servlet，转发到该servlet，然后在该servlet中发布到外部站点。这里有没有人有幸做了我想做的事情，或者知道这是否可能

forward.jsp：

<%@ page session="false" %>
<%@ page import="com.day.cq.wcm.foundation.forms.FormsHelper" %>

<%@ taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0" %>
<sling:defineObjects/>

<%
FormsHelper.setForwardPath(slingRequest, "http://localhost:8080/rest/foo", true);
%>

方法

FormsHelper.setForwardPath

只能用于将请求转发到同一CQ实例上的不同servlet。这就是forward方法的用途，您不能使用它向外部服务器发出请求。描述转发和重定向之间的区别。重定向无法强制浏览器发送帖子，因此也无法解决问题

如果您想要创建一个标准的CQ表单来发布到外部服务器，那么外部请求应该在服务器端完成。创建一个CQ servlet，用于处理表单请求并使用库向外部站点发送POST

CQ 5.6.1包含commons httpclient 3.1

如果CQ根本不需要了解表单数据，您可以将表单上的操作设置为外部URL。或者，如果希望用户留在站点上，可以通过AJAX将表单数据提交到外部站点。无论哪种方式，都可以避免将请求重定向到服务器端的外部站点

对，这就是我“害怕”的地方。这并不难，但这只是乏味的工作，不应该是必要的。在我们的例子中，CQ根本不需要知道表单数据或表单数据是否已提交。在编辑之前，我看到了您最初的一组建议，但我同意这可能是最好的方法。感谢您的回复。如原始问题中所述，要求使用标准CQ表单组件。据我所知，你的建议没有一个是可能的。如果我只是使用自己的组件编写一个简单的表单，那么当然。我错过什么了吗？
