[英]Parsing JSON array to individual variables in Azure logic apps
我正在尝试编写一个逻辑应用程序来解析 Json Object 和更新 salesforce 记录。 我对 Salesforce 和 Azure 逻辑应用程序都很陌生,所以我想弄清楚这一点。 下面是我的 Json 文件
{
"ContactId": null,
"Email": "asong@uog.com",
"IsInternalUpdate": false,
"Preferences": [
{
"PrefCode": "EmailOptIn",
"CurrentValue": "Yes",
"Locale": "en-US"
},
{
"PrefCode": "MobilePhone",
"CurrentValue": "1234567890",
"Locale": "en-US"
},
{
"PrefCode": "SMSOptIn",
"CurrentValue": "Yes",
"Locale": "en-US"
},
{
"PrefCode": "ProductTrends",
"CurrentValue": "ProductTrends,OffersPromotions",
"Locale": "en-US"
},
]
}
基于 email 值,我需要更新 Salesforce 中的自定义 object。从首选项数组中,Prefcode 值映射到 Salesforce 中的一个字段,Current 值映射到字段值。 即下面的代码片段翻译为将 Salesforce 中的 EmailOptIn 字段的值设置为“是”
{
"PrefCode": "EmailOptIn",
"CurrentValue": "Yes",
"Locale": "en-US"
}
到目前为止,我能够传递硬编码值并从逻辑应用程序成功更新 salesforce 记录。
我正在尝试为每个字段设置单独的变量,以便我可以将其直接传递给 salesforce。我遇到了两个问题
{
"PrefCode": "ProductTrends",
"CurrentValue": "ProductTrends,OffersPromotions",
"Locale": "en-US"
}
以下是我的逻辑应用程序结构
- 捕获字段值映射的最佳方法是什么?
我可以通过构建具有所需详细信息的 JSON 并再次使用解析 JSON 步骤来实现您的要求。 以下是为我工作的逻辑应用程序的流程。
- 我有几个字段允许多选 select,如何设置多选值。 下面是一个例子
我已将ProductTrends
转换为数组并使用其索引检索每个项目,如下所示。
array(split(body('Parse_JSON_2')?['ProductTrends'],','))[0]
array(split(body('Parse_JSON_2')?['ProductTrends'],','))[1]
或者,如果可以使多个值的目标端工作,您可以将数组或字符串直接发送到 salesforce。
下面是我的逻辑应用程序的完整 JSON。

按照上述过程后,我可以单独获取偏好值。
