在 Azure 数据工厂中将内容作为主体传递的问题

Question

我正在 Azure 数据工厂中调用 Azure 函数（HTTP 触发器），正文来自查找 activity (@activity('Lookup1').output.value) 是这样的

"body":[
        {
            "BaseObject": "2|03|01|01",
            "BaseObjectDescription": "Cent",
            "CreateDate": "30.09.2021"
        },
        {
            "BaseObject": "9|03|01|01",
            "BaseObjectDescription": "Pent",
            "CreateDate": "30.09.2021"
        }]

上面的 json 当作为正文传递给 Azure 函数 activity 时，我收到错误消息“解析值时遇到意外字符：S”。但是，如果我在 Azure 函数体中硬编码并传递相同的值，我就会得到输出。当我对其进行硬编码时，我在调试模式下看到正文是这样传递的

"body": "[\n        {\n            \"BaseObject\": \"02|03|01|01\",\n            \"BaseObjectDescription\": \"Cent\",\n            \"CreateDate\": \"30.09.2021\" },\n        {\n            \"BaseObject\": \"04|03|01|01\",\n            \"BaseObjectDescription\": \"Pent",\n            \"CreateDate\": \"21.09.2021\",\n },\n]"

所以问题是如何将我从查找 activity 得到的 json 更改为类似上面的内容，以便我的函数将其识别为 Azure 数据工厂中的正文。

这是我的 Azure Function Linked Service 配置。为什么在 Azure 门户中打开被禁用。我在 ADF for Azure Function Activity 中得到的错误是

"
Call to provided Azure function 'Function1' failed with status-'InternalServerError' and message - 'Invoking Azure function failed with HttpStatusCode - InternalServerError.'." While in Azure Function Logs I see the error message as below:

Answer 1

在 Azure 函数 activity.

的主体内使用 查找 activity 值作为 @activity('Lookup1').output.value[0]

查找activity输出：

Azure 函数 activity 设置：

正文: @activity('Lookup1').output.value[0]

Azure 函数输入中显示的值：
