使用NodeJS显示Mongodb的图像

Question

我有一个＆＃34; 图片＆＃34;和＆＃34; image_ids ＆＃34;在我的mongoDB中：

图片

{
        "_id" : ObjectId("542e65368a1cec1227ae2bac"),
        "reference" : "5424991"
}

images_ids：

{
        "_id" : ObjectId("542e652995ac12ed3fecb85f"),
        "image" : "D0000001.PNG",
        "fid" : ObjectId("542e65368a1cec1227ae2bac"),
        "reference" : "5424991"
}

如何使用NodeJS显示D0000001.PNG？我的意思是，与API进行链接。
