从HTTP文件源解析GeoJSON数据 [英] Parsing GeoJSON data from HTTP file source
问题描述
我有一个我想要在Data Factory中摄取的远程资源,其格式为GeoJSON,例如这个[1]。
I have got a remote resource I'd like to ingest in Data Factory which is formatted as GeoJSON, such as this one [1].
我没有管理设置HTTP文件源数据集以成功解析它。无论我放置什么设置,JSON都被认为是无效的。有没有办法告诉Data Factory从"功能"开始解析?节点?如果我手动下载文件编辑它以产生具有"特征"的JSON文档,它的工作量为
。作为根节点。
I did not manage to set up a HTTP file source dataset to parse it successfully. Regardless of the settings I put, the JSON is considered invalid. Is there a way to basically tell Data Factory to start parsing from the "features" node? It works if I manually download the file edit it to produce a JSON document with "features" as the root node.

推荐答案
我可以想到一种方法。
I can think of one way of doing so.
- 您可以使用查找活动从源中提取数据。(https://docs.microsoft.com/en-us/azure/data- factory / control-flow-lookup-activity)
- 您可以在自定义活动中使用此查找活动的结果来转换数据。(https://docs.microsoft.com/en-us/ azure / data-factory / transform-data-using-dotnet-custom-activity)
- 转换后,您可以进行最终的复制活动。
希望这会有所帮助。
