在 azure 逻辑应用程序中，我想保存以 json 字符串中的 url 形式给出的图像。它们应该保存在共享点文件夹中。 json 字符串很长，但缩短后看起来有点像这样:
{"id":"123","Person":{"Name":"Testmann","Firstname":"Tim"},"Timestamp":"2023-03-22T20:16:04.663252+01 :00","Tree":{"fileId":"123","fileName":"Tree_2023_03_22_19_16_09.png","timestamp":"2023-03-22T19:16:09.082243Z","contentType":"图片/png","size":123,"url":"https://path"}}
在此示例中，蒂姆·泰斯特曼 (Tim Testmann) 在特定时间拍摄了一棵树的照片。该字符串可以包含多个图像，例如树的根部，不知道会提前出现多少个图像。
有人知道如何将图像保存在sharepoint中吗？人们可能必须首先从字符串中提取所有图像。
非常感谢您的帮助!非常感谢任何帮助。
编辑:
实际的 json 看起来更像下面的版本。有一般信息以及相同 json 类型的多个图像。如何只提取图像并将每张图像保存在共享点中？再次感谢!
{"id":"123","Person":{"Name":"Testmann","Firstname":"Tim"},"Timestamp":"2023-03-22T20:16:04.663252+01 :00","Tree1":{"fileId":"123","fileName":"Tree_2023_03_22_19_16_09.png","时间戳":"2023-03-22T19:16:09.082243Z","contentType":"图片/png","size":63865,"url":"https://path"},"Tree2":{"fileId":"1234","fileName":"Tree2_2023_03_22_19_16_09.png","时间戳": "2023-03-22T19:16:09.082243Z","contentType":"image/png","size":63865,"url":"https://path2","Tree3":{"fileId": “12345”，“文件名”:“Tree3_2023_03_22_19_16_09.png”，“时间戳”:“2023-03-22T19:16:09.082243Z”，“contentType”:“image/png”，“大小”:63865，“url” :“https://path3”}}
最佳答案
从我这边复制后，我可以按照以下步骤实现您的要求。
为了演示目的，我使用了下面的 Json 来获取示例图像 URL。
{
"id": "123",
"Person": {
"Name": "Testmann",
"Firstname": "Tim"
},
"Timestamp": "2023-03-22T20:16:04.663252+01:00",
"Tree": {
"fileId": "123",
"fileName": "Tree_2023_03_22_19_16_09.png",
"timestamp": "2023-03-22T19:16:09.082243Z",
"contentType": "image/png",
"size": 123,
"url": "https://www.thewowstyle.com/wp-content/uploads/2015/02/now-i-am-free.jpg"
}
}
