为什么从Sharepoint下载.xlsx的Python脚本仅在某些URL中失败？

使用Python Office365 REST Python客户端，我编写了以下Python函数从Sharepoint下载Excel电子表格（基于上的答案）

导入系统 从URLPRASE导入URLPRASE 从office365.runtime.auth.authentication\u上下文导入AuthenticationContext 从office365.sharepoint.client\u上下文导入ClientContext 从office365.sharepoint.file导入文件

xmlErrText=“我认为区别在于URL本身。失败的URL中是否有空格？相同的文件是否始终失败，或者它是否改变了哪些文件成功，哪些文件失败？您是否搜索了错误消息中包含的错误代码（-2130575338，或十六进制的0x81020016）？它似乎与

ClientErrorCodes.ListItemDeleted

错误（）。可能该项目已被删除，但仍缓存在您的浏览器中？此错误似乎还有其他原因，但我对SharePoint不太熟悉，因此无法针对此情况筛选相关网页。我只是希望这能让您找到正确的方向：-）我怀疑@wovano的做法是正确的。或许可以尝试检索文件的属性或版本控制信息，看看是否有效？可能文件已被删除、重新添加或从回收站返回，但删除标志尚未重置或仍在缓存中？查看文件的历史记录，它似乎从未被删除。但它已被移动。我无法从其旧位置下载，即使在浏览器中也是如此。B但我可以从浏览器中的新位置下载，但不能使用脚本。我不是Sharepoint专家，我不确定还需要寻找什么。
