c# - SalesForce 出站消息监听器上的 System.IndexOutOfRangeException

Question

我在 ASMX 中有一个网络服务，我正在尝试创建一个监听器，这是我在 webservice.cs 文件中拥有的内容

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Script.Services;
using System.Web.Services;

/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
class MyNotificationListener : NotificationBinding
{
    [WebMethod]
    [ScriptMethod(UseHttpGet = true)]

    public notificationsResponse Notifications(notifications n)
    {
        Method.SendMail("info@domain.com", "test@domain.com", "Here I am ", "I am loaded ", "", "");// This is to see if it loaded
        notificationsResponse r = new notificationsResponse();
        r.Ack = true;
        return r;
    }

}

在我的出站消息配置中，我像这样调用此 Web 服务 www.domain/webservice.asmx/Notification 但是当我加载此服务时，我看到以下内容:

`System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at System.Web.Services.Protocols.HttpServerType..ctor(Type type)
   at System.Web.Services.Protocols.HttpServerProtocol.Initialize()
   at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)`

在我的配置文件中有以下内容

`<webServices>
      <protocols>
        <add name="HttpGet"/>
        <add name="HttpPost"/>
        <add name="HttpSoap" />
      </protocols>
    </webServices>`

这是我在通知对象中的内容，它是按照 this 中的指示使用 wsdl.exe 从 WSDL 文件生成到类的例子。

    }

        }
        set {

        }
    }

    public string PartnerUrl {
        get {

        }
        set {
            this.partnerUrlField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("Notification")]
    public LeadNotification[] Notification {
        get {
            return this.notificationField;
        }
        set {
            this.notificationField = value;
        }
    }
}

Answer 1

因此，在查看您的代码后，我发现在您的 Web 服务中，公共(public)接口(interface)的实现被命名为错误，当我使用来自 salesforce 的 WSDL 生成类时，它创建了接口(interface)及其命名的 INotificationBinding 不是 NotificationBinding，这让我认为您没有从 wsdl 正确创建类，在上面显示的示例中，您正在关注使用 wsdl.exe/serverInterface 线索。 wsdl.

您是否使用 wsdl.exe 创建了上述类通知？如果是这样，您是否确保它使用的是 /serverInterface 选项，这很重要(见下图)，在 salesforce 上它清楚地提到你需要实现一个调用通知接口(interface)的类，如果处理不当，它将给出 System.IndexOutOfRangeException

的错误

请使用服务器接口(interface)选项重试。那应该可以解决问题。
