【问题描述】：

我正在调用我的 Parse 服务器并使用 Parse javascript API 将数据拉入我的 Angular V1（是 JS 还是 IO？！）应用程序。我的调用函数如下：

$scope.getInventoryItems = function () 

    var query = new Parse.Query("Inventory");
    query.include("product");
    query.include("retailer");
    query.find(

        success: function (results) 

            $scope.inventoryItems = [];

            for (i = 0; i < results.length; i++) 

                var p = results[i].get("product");
                var r = results[i].get("retailer");

                var inventoryItem = 

                    objectId: results[i].id,
                    productObjectId: p.id,
                    barcode: p.get("barcode"),
                    productName: p.get("name"),
                    imageUrl: p.get("image"),
                    Qty: results[i].get("QTY"),
                    newQty: results[i].get("QTY"),
                    shoppingQty: 1,
                    retailerImage: r.get.Logo("url"),
                    retailerName: r.get("Name")
                
                console.log(inventoryItem);
                $scope.inventoryItems[$scope.inventoryItems.length] = inventoryItem;

            

            $scope.$apply();

        ,
        error: function (error) 
            console.log("Query Error: " + error.message);
        
    )

这是 JSON 服务器响应：

    "results": [
        "objectId": "Fo02snRmlP",
        "product": 
            "objectId": "eCA7BwB7kF",
            "barcode": 54775912,

            "updatedAt": "2017-11-22T01:28:16.605Z",
            "__type": "Object",
            "className": "Products"
        ,
        "QTY": 4,
        "createdAt": "2017-11-22T01:28:16.859Z",
        "updatedAt": "2017-11-22T01:28:16.859Z",
        "ACL": 
            "NV6ubzeAHL": 
                "read": true,
                "write": true
            
"retailer": 
            "objectId": "u2qNoKDAWV",
            "Name": "My Supermarket",
            "createdAt": "2017-09-20T17:16:48.151Z",
            "updatedAt": "2017-11-13T19:40:26.371Z",
            "Logo": 
                "__type": "File",
                "name": "c600325c63f7fb252b36c08c8c6168ab_supermarket_logo_full.svg",
                "url": "https://my-api.herokuapp.com//files/my-api/c600325c63f7fb252b36c08c8c6168ab_supermarket_logo_full.svg"
            ,
            "shortName": "supermarket",
            "__type": "Object",
            "className": "Retailers"
        ,
        
    , 

一切都成功了，除了我尝试使用retailerImage: r.get.Logo("url") 收集的徽标 URL。我如何获得这个双嵌套项？

谢谢

【问题讨论】：

r.get:ACL.Logo('url')

【参考方案1】：

Logo 是retailer 的另一个属性，对吧？看起来你只需要使用r.get('Logo').url()

这是parse docs example：

var profilePhoto = profile.get("photoFile");
$("profileImg")[0].src = profilePhoto.url();

【讨论】：

就是这样。谢谢！

很高兴为您提供帮助！ :D
