U站图片服务器端逻辑

公司zhe800

tao800_fire 项目共提供了 3 个接口为Ｕ站服务.

1. 描述: 提供U站需要上传的deal图片
   url: http://zapi.zhe800.com/inner/taobao_image_urls?page=1
   type: Get

#u站商品图片链接上传接口
def taobao_image_urls
  deals = Redis.current.lrange('redis_taobao_deal_id',100*(params[:page].to_i - 1),100* params[:page].to_i - 1)
  if deals.present?
    items = Deal.select('id,image').where(id: deals)
  else
    items = Deal.select('deals.id,deals.image').joins(:deal_info)
              .not_expired.where("deal_infos.taobao_image_url = ''")
              .order('deals.updated_at DESC').page(params[:page]).per(100)
  end
  result = {}
  items.each do |item|
    result["deal-#{item.id}"] = item.image_url(:normal) if item.image_url(:normal).present?
  end
  render :json => {:result => result}
end

把 taobao deal id 放在 redis里面，是由 http://redmine.tuan800-inc.com/issues/90922 这个工单审核的。

1. 描述: 提供U站需要上传的 品牌团 logo 图片
   url: http://zapi.zhe800.com/inner/taobao_brand_image_urls?page=1
   type: Get

#u站品牌图片链接上传接口
def taobao_brand_image_urls
  brands = Brand.where("(`uz_logo_small_image_url` = '' AND logo_image <> '') OR
                        (`uz_logo_normal_image_url` = '' AND logo_image <> '') OR
                        (`uz_banner_image_url` = '' AND banner_image <> '')
                      ").order('updated_at DESC')
  items = brands.page(params[:page]).per(100)
  result = {}
  items.each do |item|
    result["brand-#{item.id}-logo_small_image"] = item.logo_image_url(:small) if item.logo_image_url(:small).present?   
    result["brand-#{item.id}-logo_normal_image"] = item.logo_image_url(:normal) if item.logo_image_url(:normal).present?
    result["brand-#{item.id}-banner_image"] = item.banner_image_url if item.banner_image_url.present?
  end
  render :json => {:result => result}     
end

这段代码逻辑也不用说了，一看就明白了

1. 描述：接受U站上传后的图片，更新tao800_fire数据库
   url: http://zapi.zhe800.com/inner/taobao_image_urls
   type: Post

def update_taobao_image_urls                                
  JSON.parse(params[:result]).each do |key,image_url|       
    key = key.split("-")                                    
    if key[0].to_s == 'deal'                                
      info = DealInfo.find_by_deal_id(key[1].to_i)          
      info.update_attributes(:taobao_image_url => image_url)
    else                                                    
      attribute = "uz_#{key[2]}_url=".to_sym                
      brand = Brand.find_by_id(key[1].to_i)                 
      brand.send(attribute, image_url)                      
      brand.save(:validate => false)                        
    end                                                     
  end                                                       
  render :text => ""                                        
end

这段代码一看就能明白的
