我收到了可怕的“客户端发现响应内容类型为“text/html”但预期为“test/xml”错误,但经过一番谷歌搜索后,我发现了这篇关于如何返回 SoapException 的帖子。
所以我继续并实现了它,但现在我仍然遇到同样的错误。是否需要在客户端进行更改才能接受 SoapException(我不这么认为,一切都只是从 Exception 继承,对吗?)
为什么我仍然在客户端收到可怕的响应?
[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,但我仍然在客户端收到 System.InvalidOperationException。
Edit2:如果有帮助/很重要,我将通过 WebReference(调用 *.asmx 文件)连接到 Web 服务。
Edit3:这是写入我们的异常日志服务器端的内容(在 PublishingManager.Publish() 调用中)。我的想法是这应该是返回给客户的东西......

Edit3:只是想抛出这个额外的代码块,以便人们看到我是如何测试这些异常的(也许这是错误的测试方式......)。在我的第一个代码块中,我在 try 块中调用了“return Components.PWD.GetConversionErrors();”,这是该方法:
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;
}
}
正如你所看到的,我已经注释掉了实际的调用,只是加入了我自己的行,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);
}
}
Edit5:Fiddler2 看到了什么:
