Nop Commerce 自动重定向到不同 URL

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 url。例如-

这是应该去的 url -

在地址栏中单击甚至粘贴时，我调试了代码并在 application_beginrequest 方法中注意到 url -

（注意 Request 对象的 Path 属性）

它自动从 category_whisky-american-sour-mash 更改为 shipping-and-returns。检查了类别和页面中的 SEO url，但没有重复项。

我检查了 SEO urls 并且只有一个条目，所以没有可能的复制方式

我已经花了将近一天的时间来解决这个问题。有人可以帮忙吗？为什么会这样？我对 NopCommerce 比较陌生。任何建议表示赞赏。

好的，经过一天半的尝试，我终于找到了修复方法。我想我应该post这里的解决方案。

这是由于错误的 Slug 值。在 UrlRecordService 中，如果未找到 slug -

，则此方法通过放置 "" 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;
                });
            }
        }

最后创建了很多带有空白 slug 的 url。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，使其忽略空格 - 和

然后添加检查以忽略带有 isActive = False -

的 slug

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;
        });
    }
}

        query = query.Where(ur => ur.Slug.Contains(slug) && ur.IsActive); // 2 add IsActive check

另外不要忘记清除 cookie 并重启服务器以防万一。

到目前为止，这已经解决了我的问题。
