Question

我有一个管道，可以遍历文件并将它们复制到存储位置。

baseURL 和 relativeURL 存储在一个 json 文件中。

我可以读入这个文件并且它是有效的。

我已经参数化了链接服务的 baseURL，这在从链接服务和数据集进行测试时有效。

然而，当我尝试调试管道时，出现错误：

<块引用>

"code":"BadRequest"
“消息”：空
"目标":"管道//runid/310b8ac1-2ce6-4c7c-a1ad-433ee9019e9b"
"详细信息":null
“错误”：空

从管道中的活动看来，传递的是空值而不是 baseURL。

我已经迭代了我的配置文件中的值，它正在被读取并且值是正确的。管道似乎没有为 baseURL 传递正确的值。

我是否必须修改管道背后的 json 代码才能使其工作？

如果有帮助，链接服务、数据集和管道的 json 如下：

--链接服务：

"name": "ls_http_opendata_ecdc_europe_eu",
"properties": {
    "parameters": {
        "baseURL": {

}
}

我重现了您的错误。

{"code":"BadRequest","message":null,"target":"pipeline//runid/abd35329-3625-490b-85cf-f6d0de3dac86","details":null,"error":null}

这是因为您没有将 baseURL 传递给源数据集中的链接服务。请这样做：

Dataset JSON 代码应该是这样的：

{
    "name": "ds_ecdc_raw_csv_http",
    "properties": {
        "linkedServiceName": {
            "referenceName": "ls_http_opendata_ecdc_europe_eu",
            "type": "LinkedServiceReference",
            "parameters": {
                "baseURL": {
                    "value": "@dataset().baseURL",
                    "type": "Expression"
                }
            }
        },
        "parameters": {
            "relativeURL": {
                "type": "string"
            },
            "baseURL": {
                "type": "string"
            }
        },
        "annotations": [],
        "type": "DelimitedText",
        "typeProperties": {
            "location": {
                "type": "HttpServerLocation",
                "relativeUrl": {
                    "value": "@dataset().relativeURL",
                    "type": "Expression"
                }
            },
            "columnDelimiter": ",",
            "escapeChar": "\\",
            "firstRowAsHeader": true,
            "quoteChar": "\""
        },
        "schema": []
    }
}

NULL 从管道传递到链接的服务 baseURL
