执行CosmosDB存储过程时出错

问题描述 投票:0回答:1

我正在学习根据以下信息编写CosmosDB存储过程

Stored procedure docs

我想做的是遍历查询返回的许多文档,并找到最匹配的文档。

流程如下

  1. 检查开始和结束日期以确保其有效文件1.5检查输入的VariantNo是否包含在文档的Variants数组中]
  2. 检查用户是否包含在文档的用户数组中,或者是否在数组中将ALL指定为字符串
  3. 检查商店数组中是否包含商店,或者是否在商店数组中将ALL指定为字符串
  4. 文档外观如下

{
    "id": "12345",
    "brand": "XXX",
    "PromotionName": "Test Promo 1",
    "PromotionType": "Deal",
    "PromotionSticker": "Sticker 1",
    "StartDate": "2020-05-14T00:00:00.1212122Z",
    "EndDate": "2020-05-30T00:00:00.1212122Z",
    "Variants": [
        "0628462008001",
        "0628462008002",
        "0644324003002"
    ],
    "Stores": [
        "SE0623"
    ],
    "Users": [
        "ALL"
    ],
    "DiscountInPercent": "30",
    "RedPriceStores": null,
    "CreatedDate": "20200515",
    "CreatedBy": "SLAPI Promotions API ClientId: 123",
    "UpdatedDate": null,
    "UpdatedBy": null,
    "Consumer": "YYYYY_V2",
    "_rid": "HwVmAIFaOoEBAAAAAAAAAA==",
    "_self": "dbs/HwVmAA==/colls/HwVmAIFaOoE=/docs/HwVmAIFaOoEBAAAAAAAAAA==/",
    "_etag": "\"11005859-0000-0c00-0000-5ebe0f7e0000\"",
    "_attachments": "attachments/",
    "_ts": 1589514110
}

基于CosmosDB中的模板,存储过程的开头看起来像这样

// SAMPLE STORED PROCEDURE
function getFinalPromotionPrice(item, store, user) {
    var collection = getContext().getCollection();

    // Query documents and take 1st item.
    var isAccepted = collection.queryDocuments(
        collection.getSelfLink(),
        'SELECT * FROM c WHERE c.StartDate <= (SELECT VALUE GetCurrentDateTime()) AND c.EndDate >= (SELECT VALUE GetCurrentDateTime())',
    function (err, feed, options) {
        if (err) throw err;

        // Check the feed and if empty, set the body to 'no docs found', 
        // else take 1st element from feed
        if (!feed || !feed.length) {
            var response = getContext().getResponse();
            response.setBody('no docs found');
        }
        else {
            var response = getContext().getResponse();
            var body = { prefix: prefix, feed: feed[0] };
            response.setBody(JSON.stringify(body));
        }
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
}

但是执行存储过程时出现此错误:

{“代码”:400,“正文”:{“代码”:“ BadRequest”,“消息”:“消息:{\”错误\“:[\”执行功能时遇到异常。异常= ReferenceError:未定义'prefix'\ r \ n堆栈跟踪:ReferenceError:未定义'prefix'\ n在匿名函数(script.js:20:13)\ n在A

您可以检查错误,它期望使用“前缀”:
