如何创建WCF服务重定向？ [英] How to create a redirection for WCF service?

问题描述

我主持在我的网站A.一个WCF服务，我有另外一个网站B，一个重定向到使用IIS的URL重写我的网站的所有请求。然而，站点B不处理任何请求.SVC文件，返回404未找​​到。任何想法如何使它工作？

I have a WCF service hosted on my website A. And I have another site B, that redirects all requests to my site A using IIS URL rewriting. However, site B doesn't handle any requests to .svc files, returns 404 not found. Any idea how to make it working?

UPD重定向配置是这样的：

UPD redirection config is like this:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Redirect" stopProcessing="true">
                    <match url=".*" />
                    <action type="Rewrite" url="http://localhost/site_A/{R:0}" logRewrittenUrl="true" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

我发现没有到.SVC在网站A的IIS日志文件的任何请求（！）。它不重定向这些请求到现场A.然而，当我从站点B要求.htm文件，就其重定向到站点A正确。

I've found that there is no any requests to .svc files in the IIS logs of website A (!). It doesn't redirect these requests to site A. However, when I request .htm files from the site B, it redirects them to site A correctly.

推荐答案

即使你在IIS添加一个.SVC处理程序和重定向它以同样的方式为你做的.HTM请求重定向不会preserve邮件的正文。因此，在SiteB中一个服务方法的要求不一定是一样的站点A服务的方法调用 - 这取决于你的配置，无论是暴露REST风格，你的绑定是什么。

Even if you were to add a .SVC handler in IIS and redirect it in the same manner as you do the .HTM requests, the redirection will not preserve the body of the message. So a request to a service method on SiteB will not necessarily be the same as a service method call on SiteA - this depends on your configuration, whether it is exposed RESTfully, and what your bindings are.

您可以看看 WCF 4.0的路由功能。这要求你写一定的逻辑认识到一个呼叫，并调用它的另一个端点。

You can have a look at WCF 4.0's Routing feature. This requires you to write certain logic to recognize a call and have it call another endpoint.

一个较粗略的解决办法是干脆SiteB中承载它简单地接受传入的请求，并要求站点A的等价的服务，得到结果，并返回给调用者的代理服务。

A 'cruder' solution is to simply have SiteB host a proxy service which simply accepts incoming requests and calls SiteA's equivalent service, gets the result and returns it to the caller.
