使用 IIS 作为动态转发的反向代理

Question

下午好，

我需要一个反向代理解决方案来将 API 调用从服务器转发到不同的客户端。为此，我想使用带有 ARR 的 IIS。目标客户端的地址包含在服务器的 HTTP 调用中：

http://Proxyserver/Targetcomputer/API_String

我想将 URL 重写为：http://Targetcomputer/API_String

我已经使用以下模式设置了 URL 重写规则：

`^(.*)/(.*)`

这会导致以下结果：

`{R:0} Targetcomputer/API_String`
`{R:1} Targetcomputer`
`{R:2} API_String`

我使用以下表达方式进行释义：

`http://{R:1}/{R:2}`

但是，在我看来，动态重定向到

{R:1}

是不可能的。 聪明人有什么建议吗？

提前谢谢您！

创建各种转发规则没有成功 Web服务器似乎只能访问本地资源。

以下是 web.config 中的重写规则：

<rule name="Test" enabled="true" stopProcessing="true">
      <match url="^([^/]+)/([^/]+)" />
      <action type="Rewrite" url="http://{R:1}/{R:2}" LogRewrittenUrl="true" />
</rule>

更多信息，以下是失败请求日志中的详细信息：

Answer 1

尝试在您的

web.config

中使用下面的重写规则。

    <rule name="Test" enabled="true" stopProcessing="true">
  <match url="^[^/]+/([^/]+)/(.*)" />
  <action type="Rewrite" url="http://{R:1}/{R:2}" LogRewrittenUrl="true" />
</rule>

{R:1} 将捕获 Targetcomputer，{R:2} 将捕获 API_String。
