Question

我有一个非常特殊的问题。对于某些特定的url nop网站重定向到另一个网址。例如 -

这是应该去的网址 -

enter image description here

点击或甚至粘贴在地址栏中时，我调试了代码，并在application_beginrequest方法中注意了网址 -

enter image description here （注意请求对象的路径属性）

它自动从category_whisky-american-sour-mash更改为shipping-and-returns。从类别和页面检查了两个SEO网址，但没有重复。

我查了SEO网址，只有一个条目，所以没有可能的重复方式

我现在试图解决这个问题差不多一天了。有人可以帮忙吗？为什么会这样？我对NopCommerce相对较新。任何建议都表示赞赏。

好的，经过一天半的尝试，我终于找到了解决办法。我想我应该在这里发布解决方案。

这是由于错误的Slug值造成的。在UrlRecordService此方法中，如果没有找到slug，则通过放置""来缓存slug -

    public virtual string GetActiveSlug(int entityId, string entityName, int languageId)
        {
            if (_localizationSettings.LoadAllUrlRecordsOnStartup)
            {
                string key = string.Format(URLRECORD_ACTIVE_BY_ID_NAME_LANGUAGE_KEY, entityId, entityName, languageId);
                return _cacheManager.Get(key, () =>
                {
                    //load all records (we know they are cached)
                    var source = GetAllUrlRecordsCached();
                    var query = from ur in source
                                where ur.EntityId == entityId &&
                                ur.EntityName == entityName &&
                                ur.LanguageId == languageId &&
                                ur.IsActive
                                orderby ur.Id descending
                                select ur.Slug;
                    var slug = query.FirstOrDefault();
                    //little hack here. nulls aren't cacheable so set it to ""
                    if (slug == null)
                        slug = ""; //slug is blank for null
                    return slug;
                });
            }
            else
            {
                //gradual loading
                string key = string.Format(URLRECORD_ACTIVE_BY_ID_NAME_LANGUAGE_KEY, entityId, entityName, languageId);
                return _cacheManager.Get(key, () =>
                {
                    var source = _urlRecordRepository.Table;
                    var query = from ur in source
                                where ur.EntityId == entityId &&
                                ur.EntityName == entityName &&
                                ur.LanguageId == languageId &&
                                ur.IsActive
                                orderby ur.Id descending
                                select ur.Slug;
                    var slug = query.FirstOrDefault();
                    //little hack here. nulls aren't cacheable so set it to ""
                    if (slug == null)
                        slug = ""; // slug is blank for null
                    return slug;
                });
            }
        }

最终创建了许多带有空白slu ur的网址。要解决此问题，您应该执行以下操作 -

首先修改将slug转换为item的代码，以便忽略空白 - 和

然后添加检查以忽略带有isActive = False -

的slugs

public virtual UrlRecordForCaching GetBySlugCached(string slug)
{
    if (String.IsNullOrEmpty(slug))
        return null;

    if (_localizationSettings.LoadAllUrlRecordsOnStartup)
    {
        //load all records (we know they are cached)
        var source = GetAllUrlRecordsCached();
        var query = from ur in source
                    where ur.Slug.Equals(slug, StringComparison.InvariantCultureIgnoreCase)
                    && ur.IsActive // 2 add IsActive check
                    select ur;
        var urlRecordForCaching = query.FirstOrDefault();
        return urlRecordForCaching;
    }
    else
    {
        //gradual loading
        string key = string.Format(URLRECORD_BY_SLUG_KEY, slug);
        return _cacheManager.Get(key, () =>
        {
            if (string.IsNullOrEmpty(slug))  // 1 blank slug check
                return null;

            var urlRecord = GetBySlug(slug);
            if (urlRecord == null)
                return null;

            var urlRecordForCaching = Map(urlRecord);
            return urlRecordForCaching;
        });
    }
}

所以，这远远解决了我的问题。
