【问题描述】：
我对 CQ 很陌生，我已经为此苦苦挣扎了很长时间。我想要做的是“创建一个使用常规标签接受用户名密码并将数据发布到 servlet 的页面。
servlet 使用硬编码的 str.equals("username") 检查用户名密码并重定向到另一个页面，即成功或失败" 请注意，我正在构建一个拥有普通用户的网站，例如“注册到诸如 stackoverflow 等网站的人”这些用户不是可以编辑内容的不是作者。 一个非常基本的任务，但对我来说太难了。这是代码。 我使用 CRXDE 创建的捆绑包成功编写了 sling Post servlet
package com.example;
import java.io.IOException;
import javax.servlet.ServletException;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Service;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Component(immediate=true, metatype=false, label="EXAMPLE SERVLET")
@Service
@Properties(value = {
@org.apache.felix.scr.annotations.Property(name="sling.servlet.methods", value={"POST"}),
@org.apache.felix.scr.annotations.Property(name="sling.servlet.resourceTypes", value={"sling/servlet/default"}),
@org.apache.felix.scr.annotations.Property(name="sling.servlet.selectors", value={"SELECTORNAME"}),
@org.apache.felix.scr.annotations.Property(name="sling.servlet.extensions", value={"html"})
})
public class ExampleServlet extends SlingAllMethodsServlet {
private static final Logger log = LoggerFactory.getLogger(ExampleServlet.class);
private static final long serialVersionUID = 1L;
protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
//String redirect = request.getParameter(":redirect");
log.info("The Sling Post Servlet- Example Servlet has been called !! ");
String username = request.getParameter("username");
String password = request.getParameter("password");
if(username.equals("oliver")&& password.equals("oliver"))
{
response.sendRedirect("/content/mywebsite/en/products");
}
else
{
response.sendRedirect("/content/mywebsite/en/services");
}
log.info("Sucessfull Response Sent ");
}
}
I get error as
Status
200
Message
OK
Location /example.SELECTORNAME.html
Parent Location /
Path
/example.SELECTORNAME.html
Referer http://localhost:4502/content/mywebsite/en/products.html

提前致谢！！
【问题讨论】：
-
如果您的 servlet 处于活动状态，您能否检查 osgi 组件列表？ （/系统/控制台/组件）。似乎常规的 POST servlet 正在处理请求
-
ExampleServlet 处于活动状态......我检查过了！
