如何自动/安排在IIS中托管的WCF服务调用？ [英] How can I automate / schedule a WCF service call hosted in IIS?

问题描述

我为管理自己的数据导入的服务提供了一个非常简单的服务合同，类似于：

 使用System.ServiceModel; 
 
命名空间Company.Services.Domain.Contract 
 {
 [ServiceContract（Name =ImportService，Namespace =http://services.company.org/）] 
公共接口IImportService 
 {
 [OperationContract] 
 ImportResponse ImportData（）; 
} 
} 
  

我想设置一个预定任务或类似于每天执行此调用的东西。我知道我可以编写一个控制台应用程序并通过svcutil创建一个代理。 但是有没有办法在IIS本地配置它（可能是IIS扩展）？或者我可以使用PowerShell实现简单而优雅的东西吗？

只是想知道我的选择是什么。

http：/ /curl.haxx.se/

将计划任务设置为调用curl.exe，其参数适用于向Web服务的URL发出请求：

  curl -o importResponse.txt http://services.company.org/ImportService.svc/ImportData 
  

-o会将响应删除到给定名称的文本文件中。其他配置选项可在手册中找到： http://curl.haxx.se/docs/manual .html

编辑：这假设您正在公开Web服务和GET（而不是POST或SOAP）。如果您正在公开SOAP服务，那么它应该仍然相当简单，因为您没有传递任何参数。

  curl --request POST --header'Content-type：text / xml'-output importResponse.txt --data < SOAP /> http://services.company.org/ImportService.svc/ImportData 
  

或者，因为你是使用WCF，您可以同时将服务作为SOAP服务和RESTful Web服务公开，方法是在应用程序的web.config中添加一些配置：webHttpBinding，服务端点和endpointBehavior，如下所示： http://weblogs.asp.net/kiyoshi /archive/2008/10/08/wcf-using-webhttpbinding-for-rest-services.aspx

I've got an extraordinarily simple service contract for a service that manages its own data import, similar to this:

using System.ServiceModel;

namespace Company.Services.Domain.Contract
{
    [ServiceContract(Name = "ImportService", Namespace = "http://services.company.org/")]
    public interface IImportService
    {
        [OperationContract]
        ImportResponse ImportData();
    }
}

I'd like to set up a scheduled task or something similar to execute this call on a daily basis. I know that I could write a console application and create a proxy via svcutil. But is there a way to configure this in IIS natively (maybe an IIS extension)? Or could I achieve something simple and elegant with PowerShell?

Just wondering what my options are.

解决方案

You could use cURL (Windows and 'nix versions available): http://curl.haxx.se/

Set your scheduled task to invoke curl.exe with parameters appropriate to make a request to your web service's URL:

curl -o importResponse.txt http://services.company.org/ImportService.svc/ImportData

The -o will drop the response into a text file of the given name. Other configuration options can be found in the manual: http://curl.haxx.se/docs/manual.html

EDIT: This assumes that you're exposing a web service and GET (rather than POST or SOAP). If you're exposing a SOAP service it should still be fairly trivial because you're not passing any parameters.

curl --request POST --header 'Content-type: text/xml' --output importResponse.txt --data <SOAP/> http://services.company.org/ImportService.svc/ImportData

Alternatively, as you're using WCF you can expose your service as both a SOAP service and a RESTful web service simultaneously, by adding some configuration to your app's web.config: a webHttpBinding, a service endpoint, and an endpointBehavior, as per: http://weblogs.asp.net/kiyoshi/archive/2008/10/08/wcf-using-webhttpbinding-for-rest-services.aspx
