当文件夹名称中使用百分号 (%) 时，Sharepoint REST API GetFolderByServerRelativePath 返回错误

Question

我使用HTTP post方式上传文件，如下图：

POST https://sitename.sharepoint.com/sites/subsitename/pagename/_api/web/getfolderbyserverrelativepath(decodedurl=@t)/files/addusingpath(overwrite=true,decodedurl=@f)?@t='docs/%24%26%2B%2C%3B%3D%40%23%25%7B++++%7D%5E%7E%5B%5D%60'&@f='new.docx' HTTP/1.1

    Authorization: "Bearer " + accessToken
    accept: "application/json;odata=verbose"
    content-type: "application/json;odata=verbose"

它适用于任何文件和文件夹，但文件夹名称中带有百分号（“%”）的文件夹除外。如果目标文件夹名称包含百分号（“%”），则会返回错误并显示消息：

{"error":{"code":"-2147024893, System.IO.DirectoryNotFoundException","message":{"lang":"en-US","value":"File Not Found."}}}

我找到了相关文章：https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/supporting-and-in-file-and-folder-with-the-resourcepath-api

因此，我尝试使用另一种post方法：

POST https://sitename.sharepoint.com/sites/subsitename/pagename/_api/web/getfolderbyserverrelativepath(decodedurl=@t)/files/addstubusingpath(decodedurl=@f)?@t='docs/%24%26%2B%2C%3B%3D%40%23%25%7B++++%7D%5E%7E%5B%5D%60'&@f='new.docx' HTTP/1.1

    Authorization: "Bearer " + accessToken
    accept: "application/json;odata=verbose"
    content-type: "application/json;odata=verbose"

但我得到了如下回复：

{"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"Not well formatted JSON stream."}}}

这是怎么回事？

Answer 1

问题在于将空格符号编码为“%20”而不是“+”，并使用下面的查询创建文件夹：

/_api/web/folders/AddUsingPath(decodedurl="folder%20name") 

然后通过查询将文件添加到文件夹中：

_api/web/getfolderbyserverrelativepath(decodedurl='docs/%24%26%2B%2C%3B%3D%40%23%25%7B%20%20%20%20%7D%5E%7E%5B%5D%60')/files/AddUsingPath(overwrite=true,decodedurl='new.docx')

现在效果很好。
