如何使用码头重写请求

时间：2019-09-18 11:37:45

标签： angular jetty jetty-9

我已经建立了一个独立的Jetty服务器（版本9.4.19）并向其部署了Angular 8应用程序。 基本href看起来像这样：<base href="/myapp/">。

我可以通过<server-ip>:8080/myapp/访问该应用程序。 我知道，我必须为码头实施重写规则，以将<server-ip>:8080/myapp/*形式的任何请求引回到index.html，以便angular处理请求。

我激活了重写模块（java -jar start.jar add-to-start=rewrite）。然后，我编辑了jetty-rewrite.xml文件并尝试添加规则。该文件如下所示：

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

<Configure id="Server" class="org.eclipse.jetty.server.Server">

  <!-- =========================================================== -->
  <!-- configure rewrite handler                                   -->
  <!-- =========================================================== -->
  <Call name="insertHandler">
    <Arg>
      <New class="org.eclipse.jetty.rewrite.handler.RewriteHandler">
        <Set name="rewriteRequestURI"><Property name="jetty.rewrite.rewriteRequestURI" deprecated="rewrite.rewriteRequestURI" default="true"/></Set>
        <Set name="rewritePathInfo"><Property name="jetty.rewrite.rewritePathInfo" deprecated="rewrite.rewritePathInfo" default="false"/></Set>
        <Set name="originalPathAttribute"><Property name="jetty.rewrite.originalPathAttribute" deprecated="rewrite.originalPathAttribute" default="requestedPath"/></Set>

        <!-- Set DispatcherTypes  -->
        <Set name="dispatcherTypes">
          <Array type="javax.servlet.DispatcherType">
            <Item><Call class="javax.servlet.DispatcherType" name="valueOf"><Arg>REQUEST</Arg></Call></Item>
            <Item><Call class="javax.servlet.DispatcherType" name="valueOf"><Arg>ASYNC</Arg></Call></Item>
          </Array>
        </Set>

        <!--<Get id="Rewrite" name="ruleContainer"/>-->

        <Call name="addRule">
          <Arg>
            <New class="org.eclipse.jetty.rewrite.handler.RewritePatternRule">
              <Set name="pattern">/myapp/*</Set>
              <Set name="replacement">/myapp/</Set>
            </New>
          </Arg>
        </Call>

        <!-- see rewrite-compactpath.xml for example how to add a rule -->

      </New>
    </Arg>
  </Call>
</Configure>

当我在应用程序中刷新页面时，收到404错误消息。我想这意味着重写不起作用。

我试图将重写目标更改为<Set name="replacement">/</Set>和<Set name="replacement">/myapp/index.html</Set>，但这也不起作用。

有人可以指出我正确的方向吗？

编辑：

我发现：当我将RewritePatternRule的模式更改为应用程序的特定部分（例如<Set name="pattern">/myapp/dashboard</Set>）并从该页面刷新时，重写工作正常，但不适用于应用程序的其他部分。

答案 0 :(得分：0)

RewritePatternRule将重写模式部分，而将pathInfo部分保留下来。

如果您将org.eclipse.jetty.rewrite的日志记录级别设置为DEBUG，则会看到... 

[DEBUG]:oejrh.RuleContainer: applied org.eclipse.jetty.rewrite.handler.RewritePatternRule[ht][/myapp/*][/myapp/]
[DEBUG]:oejrh.RuleContainer: rewrote /myapp/alt.html to /myapp/alt.html

如果您切换到RewriteRegexRule，则可以更好地控制内容。

示例设置...
