我得到了可怕的"客户端发现的响应内容类型" text / html"但期望" test / xml"错误,但在一些谷歌搜索后,我发现this post有关如何返回SoapException。
所以我继续实施,但现在我仍然得到同样的错误。我是否需要在客户端进行更改以便能够接受SoapException(我不会这么认为,所有内容都只是从Exception继承而来,对吧?)
为什么我仍然在客户端获得可怕的回应?
[WebMethod]
[SoapHeader("authenticationHeader")]
[WebServiceAuthentication(AuthenticationRequired = false)]
public DataSet GetConversionErrors()
{
try
{
return Components.PWD.GetConversionErrors();
}
catch (Exception ex)
{
PublishingManager.Publish(ex, HttpContext.Current.User.Identity.Name);
throw Components.SoapException.GenerateSoapException(ex, Context);
}
}
编辑:我知道这个catch块中的异常正是我需要看到的,但我仍然在客户端获得System.InvalidOperationException。
Edit2:我通过WebReference(调用* .asmx文件)连接到webservices,如果这有帮助/重要。
Edit3:这是我们的异常日志服务器端(在PublishingManager.Publish()调用中)的内容。我的想法是,这应该是归还给客户的......

Edit3:只想抛出这个额外的代码块,以便人们看到我如何测试这些异常(也许这是测试的错误方法......)。在我的第一个代码块中,我在try块中调用了#34;返回Components.PWD.GetConversionErrors();",这里是那个方法:
public static DataSet GetConversionErrors()
{
DB db = new DB();
try
{
//return db.ExecuteDataset(Configuration.GenericConfig.AppConnectionString, CommandType.Text, spGetConversionErrors);
throw new Exception("Test the text/html text/xml message.");
}
catch
{
throw;
}
}
正如您所看到的,我已经注释掉了实际的调用,并且只是投入了我自己的行,每次都会抛出异常以进行测试......
Edit4:@gbvb这是新方法:
[WebMethod]
[SoapHeader("authenticationHeader")]
[WebServiceAuthentication(AuthenticationRequired = false)]
public DataSet GetConversionErrors()
{
try
{
return Components.PWD.GetConversionErrors();
}
catch (Exception ex)
{
//PublishingManager.Publish(ex, HttpContext.Current.User.Identity.Name);
//throw Components.SoapException.GenerateSoapException(ex, Context);
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
System.Xml.XmlNode detailNode = xmlDoc.CreateNode(System.Xml.XmlNodeType.Element, System.Web.Services.Protocols.SoapException.DetailElementName.Name, System.Web.Services.Protocols.SoapException.DetailElementName.Namespace);
detailNode.InnerText = ex.ToString();
throw new System.Web.Services.Protocols.SoapException(ex.Message, System.Web.Services.Protocols.SoapException.ClientFaultCode, System.Web.HttpContext.Current.Request.Url.AbsoluteUri, detailNode, ex.InnerException);
}
}

所以,我得到了它的工作。这是我发现的:
在IIS中查看我的网站属性,然后选择“模块”时,有一个名为“CustomErrorModule”的条目正在尝试处理网站/网络服务引发的错误。
修复方法是删除该条目“CustomErrorModule”,或者从以下位置更新我的配置文件:
<httpErrors errorMode="Custom" existingResponse="Replace">
为:
<httpErrors errorMode="Custom" existingResponse="Auto">
感谢大家的帮助,它引导我朝着正确的方向前进。 (顺便说一句,我正在更新配置文件,所以我不必弄乱模块的东西)
此外,here's a link解释了这种情况。

只是为了咯咯笑,你能尝试使用SoapException.ClientFaultCode作为该调用的类型显式抛出新的SoapException()吗?显然,你有几个层可能会在你上面显示的代码中失败,很容易搞砸(相信我,我知道:))。并且不要调用其他方法,例如Publisher.publish ..这将指出它是否是消息声明(即ASMX基础结构),还是你的代码正在搞乱异常..
