WCF服务的负载平衡错误-NLB [英] Load balancing error with WCF service - NLB

问题描述

更新3:
我创建了一个Visual Studio 2008测试项目，并尝试创建对共享站点WCF服务参考的服务参考，并收到以下错误:

UPDATE 3:
I created a Visual Studio 2008 test project and tried to create a service reference to shared site WCF service reference and received the following error:

下载时出错 " http://apps.mydomain/MyService.svc ". 请求失败，HTTP状态 400:错误的请求.元数据包含一个 无法解析的参考: " http://apps.mydomain/MyService.svc ". 内容类型application/soap + xml; charset = utf-8不被支持 服务 http://apps.mydomain/MyService.svc ". 客户端和服务绑定可能是 不匹配.远程服务器返回 错误:(415)无法处理 消息，因为内容类型 'application/soap + xml; charset = utf-8' 不是预期的类型'text/xml; charset = utf-8'.如果服务是 在当前解决方案中定义，请尝试 建立解决方案并添加 再次提供服务参考.

There was an error downloading 'http://apps.mydomain/MyService.svc'. The request failed with HTTP status 400: Bad Request. Metadata contains a reference that cannot be resolved: 'http://apps.mydomain/MyService.svc'. Content Type application/soap+xml; charset=utf-8 was not supported by service http://apps.mydomain/MyService.svc'. The client and service bindings may be mismatched. The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.. If the service is defined in the current solution, try building the solution and adding the service reference again.

更新2:
@Nick-我尝试了您的建议，即使用每个服务器的标准路径明确设置每个端点的地址，但我仍然得到相同的结果.

UPDATE 2:
@Nick - I tried your suggestion of explictly setting the address of each endpoint with the fully qualified path of each server and I still get the same result.

此外，当我尝试使用共享站点URL设置listenUri属性时，我收到400错误的请求错误，而不是404错误.

Also, when I try to set the listenUri attribute with the shared site URL, I get a 400 bad request error instead of a 404 error.

更新
经过一些额外的研究，在 http://apps1.mydomain 和

UPDATE
After some additional research, there were some IIS configuration setting conflicts between http://apps1.mydomain and http://apps2.mydomain and was able to get past the "Server Application Unavailable" error.

现在，当我尝试浏览共享站点时，出现了404错误( http://apps.mydomain )，但我能够浏览到 http://apps1.mydomain 和

Now I am getting a 404 error when I tried to browse to the shared site (http://apps.mydomain), but I am able to browse to the http://apps1.mydomain and http://apps2.mydomain service reference.

原始问题

我的公司使用 Microsoft NLB 来平衡我们之间的流量IIS服务器.我最近将WCF服务部署到了每台IIS 6 Windows Server 2003 Standard Edition SP1服务器上.当我尝试使用IE 7浏览到共享域名时收到以下错误:

My companys uses Microsoft NLB to load balance traffic between our IIS servers. I recently deployed a WCF service on to each IIS 6 Windows Server 2003 Standard Edition SP1 servers. I received the following error when I tried to browse to the shared domain name using IE 7:

消费者将指向 http://apps.mydomain 来使用服务，但虚拟域已映射到 http://apps1.mydomain 或

The consumer will point to the http://apps.mydomain to use the service but virtual domain is mapped to http://apps1.mydomain or http://apps2.mydomain. If I browse to the service on each server, I do not receive that error.

该服务当前正在使用匿名basicHttpBinding.

The service is currently using a anonymous basicHttpBinding.

还有其他人遇到过这个问题吗?

历史

在开始发生此错误之前，浏览到所有三个域名时，我收到以下错误消息( http://apps.mydomain ， http://apps1.mydomain ， http://apps2.mydomain ):

Before this error started occurring, I received the following error when I broswed to all three domain name (http://apps.mydomain, http://apps1.mydomain, http://apps2.mydomain):

此收藏集已包含一个 方案http的地址.可以 每个方案中最多只能有一个地址 这个集合.

This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.

我使用了 ServiceHostFactory 类自定义我的.svc文件以指定自定义服务工厂.然后，我通过继承ServiceHostFactory并根据需要进行覆盖来创建我们的自定义工厂.

I used the ServiceHostFactory class to customize my .svc file to specify a custom service factory. Then I create our custom factory by inheriting from ServiceHostFactory and overriding as required.

public class MyFactory : ServiceHostFactory
{
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        return new ServiceHost(serviceType, baseAddresses[0]);
    }
}

<%@ ServiceHost Language="C#" Factory="MyFactory" Debug="true" Service="MyService" CodeBehind="~/App_Code/MyService.cs" %>

推荐答案

在为我的WCF服务和使用应用程序尝试了不同的配置之后.我创建了对其中一个工作服务引用( http://apps1.mydomain 或 http://apps2.mydomain ).然后，我将客户端配置中的终结点引用更改为指向共享站点WCF地址( http://apps.mydomain )，便可以使用和使用该服务.

After some experimenting with different configurations for my WCF service and consuming application. I created a service reference to one of the working service references (http://apps1.mydomain or http://apps2.mydomain) in the consuming application. Then I changed the endpoint reference in the client configuration to point to the shared site WCF address (http://apps.mydomain) and I was able to consume and use the service.
