我正在尝试使用节点的square-connect包来更新正方形库存中的一些数据，如下所示：
我正在使用firebase functions函数，该函数在Firebase数据库更新时执行代码（这就是export.updateItem的作用，该函数执行并返回数据快照）已更新）：
exports.updateItem = functions.firestore
.document('items/{itemId}')
.onUpdate((change, context) => {
// Get an object representing the document
// e.g. {'name': 'Marie', 'age': 66}
const newValue = change.after.data();
const previousValue = change.before.data();
var params = {
query: {
exact_query: {
attribute_name: "sku",
attribute_value: newValue.barcode
}
}
}
api.searchCatalogObjects(params).then(function(data) {
console.log('API called successfully in searchFor IDS. Returned data: ' + JSON.stringify(data));
var dat = data;
var variation = {
type: "ITEM_VARIATION",
id: dat.objects[0].id,
present_at_all_locations: true,
item_variation_data: {
item_id: dat.objects[0].item_variation_data.item_id,
name: "Regular",
pricing_type: "FIXED_PRICING",
price_money: {
amount: Number(newValue.price) * 100,
currency: "USD",
},
sku: newValue.barcode,
track_inventory: true
}
};
var item = {
type: 'ITEM',
id: dat.objects[0].item_variation_data.item_id,
item_data: {
name: newValue.barcode,
description: newValue.description,
variations: [variation]
}
};
const idempotencyKey = require('crypto').randomBytes(32).toString('hex');
var body = {
idempotency_key: idempotencyKey,
batches: [{
objects: [item]
}]
};
api.batchUpsertCatalogObjects(body).then(function(data) {
console.log('API called successfully in update from EditItem. Returned data: ' + JSON.stringify(data));
if(newValue.quantity != previousValue.quantity) {
var res = data;
var variationId = res.objects[0].item_data.variations[0].id;
locationApi.listLocations().then(function(data) {
console.log('API called successfully in locationApi. Returned data: ' + JSON.stringify(data));
var dat = data;
var locationId = dat.locations[0].id; // String | The ID of the item's associated location.
// String | The ID of the variation to adjust inventory information for.
//var body = new SquareConnect.V1AdjustInventoryRequest(); // V1AdjustInventoryRequest | An object containing the fields to POST for the request. See the corresponding object definition for field details.
var adjustBody = {
quantity_delta: Number(newValue.quantity) - Number(previousValue.quantity),
adjustment_type: 'MANUAL_ADJUST'
}
inventoryApi.adjustInventory(locationId, variationId, adjustBody).then(function(data) {
console.log('API called successfully in inventoryApi. Returned data: ' + JSON.stringify(data));
}, function(error) {
console.error(error);
});
}, function(error) {
console.error(error);
});
}
}, function(error) {
console.error(error);
});
}, function(error) {
console.error(error);
});
return null;
});

在Bad request信息中，您可以看到错误位于text属性中：
text: '{"errors":[{"category":"INVALID_REQUEST_ERROR","code":"VERSION_MISMATCH","detail":"Object version does not match latest database version.","field":"version"}]}'
当我查找数据时，我看到一个版本属性，例如正方形ITEM_VARIATION，它看起来像：
"version":1534208030645
您可以在上面的输出中的此文本之后的对象中看到它：
API在searchFor IDS中成功调用。返回的数据：
它出现在我搜索ITEM_VARIATION时返回的数据中。我曾尝试将此字段和值放入batchUpsertCatalogObjects请求中，但似乎无济于事-我相信尝试执行此操作时会收到另一个错误（我不记得它是什么，也无法在立即登录）。
任何帮助将不胜感激。
更新
我尝试将version: dat.objects[0].version添加到item对象，但这没有帮助。
更新
我尝试过：
var variationObj = dat.objects[0];
variationObj.item_variation_data.price_money = {amount: Number(newValue.price) * 100, currency: 'USD'};
var item = {
type: 'ITEM',
id: dat.objects[0].item_variation_data.item_id,
item_data: {
name: newValue.barcode,
description: newValue.description,
variations: [variationObj]
}
};
尽管我仍然使用相同的错误-即使当我使用从查询返回给我的相同对象时也是如此。
更新
以上更新是有效的-请参阅答案。
答案 0 :(得分：0)
似乎有效的方法是直接从响应中获取我需要的对象，然后像responseObj.xxxxxxx = xxxxxxxx一样编辑它-而不是尝试使用{}表示法自己创建一个对象-然后将该对象传递给作为必要的参数。另外，firebase deploy有时有时需要重新运行才能使更改生效。
似乎我还需要使用uspsertCatalogObject分别上传ITEM和ITEM_VARIATION，而不是将ITEM_VARITION包含在ITEM的variations字段，或将batchUpsertCatalogObject和ITEM都包含在ITEM_VARIATION数组中使用batches-似乎也不起作用。
