在 Hangfire 中禁用 PreserveCultureAttribute

Question

我正在尝试使用 Hangfire 向使用 MS Bot Framework 的用户发送预定消息。但是，所有计划的作业都失败了：

System.Globalization.CultureNotFoundException

Culture is not supported. Parameter name: name en-HK is an invalid culture identifier.

System.Globalization.CultureNotFoundException: Culture is not supported.
Parameter name: name
en-HK is an invalid culture identifier.
   at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride)
   at Hangfire.CaptureCultureAttribute.OnPerforming(PerformingContext filterContext)
   at Hangfire.Server.BackgroundJobPerformer.InvokePerformFilter(IServerFilter filter, PerformingContext preContext, Func`1 continuation)

Hangfire 文档说这是由于 Culture Preserving 和 "It is done by the PreserveCultureAttribute class that is applied to all of your methods by default."

http://docs.hangfire.io/en/v1.1.0/features.html?highlight=preservecultureattribute

如何禁用 Hangfire 中的 PreserveCultureAttribute，使其不应用于我的方法？

Answer 1

How can I disable the PreserveCultureAttribute in Hangfire so that it doesn't apply it to my methods?

我不知道如何禁用它，但您可以使用 [PreserveCulture] 属性。基于你的例外 post 我认为文化代码是错误的。检查此 link 以获得正确的文化代码。 HK 的文化代码应为 zh-HK.

Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("zh-HK");
BackgroundJob.Enqueue(() => NotifyNewComment(model.Id));

[PreserveCulture]
public static void NotifyNewComment(int commentId)
{
    var currentCultureName = Thread.CurrentThread.CurrentCulture.Name;
    if (currentCultureName != "zh-HK")
    {
        throw new InvalidOperationException(String.Format("Current culture is {0}", currentCultureName));
    }
}

希望对您有所帮助。

您可以像这样删除默认过滤器：

var filter = GlobalJobFilters.Filters.Where(x => x.Instance is CaptureCultureAttribute).Single().Instance;
GlobalJobFilters.Filters.Remove(filter);
