使用API Postman上传文件到SharePoint

Question

我想通过使用Rest API将文件上传到SharePoint，但是我尝试了以下操作却没有成功。

控制台: POST

https://test.sharepoint.com/sites/BusinessDevelopment/Shared%20Documents/Upload_BMT/_api/web/GetFolderByServerRelativeUrl('P_FIRST')/Files/add(url='abdabd.pdf',overwrite=true):

你是自己放置内容长度头部还是让Postman自动计算？ - hanut

是的，我放置了10000。 - BODYBOND

尝试移除内容长度并让其自动设置。 - hanut

是的，我移除了内容长度并使用了此URL http://test.sharepoint.com/sites/testsite/_api/web/GetFolderByServerRelativeUrl('/Library Name/Folder Name')/Files/add(url='a.txt',overwrite=true) .. 但它会出现错误：未授权操作。 - BODYBOND

@BODYBOND 我不知道如何获取“Bearer访问令牌”，你能告诉我吗？ - KevinBui

Answer 1

网址应该像下面这样

网址: http://test.sharepoint.com/sites/testsite/_api/web/GetFolderByServerRelativeUrl('/Library Name/Folder Name')/Files/add(url='a.txt',overwrite=true)

非常感谢，使用此URL后出现错误：system.unauthorizedaccessexception尝试执行未经授权的操作...我确定令牌是正确的！ - BODYBOND

如果我使用相同的令牌通过以下URL进行GET请求：https://test.sharepoint.com/_api/web/Lists/，它可以正常工作！ - BODYBOND

请检查您客户端 ID 的权限。您的客户端 ID 可能只有读取访问权限。您可以尝试授予该 ID 完全控制访问权限。 - RaytheonXie-MSFT

仍然是相同的错误。 - BODYBOND

这个错误已经修复，谢谢。 - BODYBOND

很高兴你找到了解决这个问题的方法。感谢你的分享。 - RaytheonXie-MSFT
