从Sharepoint到R的读取不断抛出403禁止访问

Question

我已经尝试了所有可以在Stack Overflow上找到的不同方法，但是它们都抛出403 Forbidden错误。我尝试过的一些代码：

library(RCurl)
webpage <- getURL("https://companyname.sharepoint.com/folder1/folder2/Shared%20Documents/filename.txt", userpwd = "[email protected]:mypassword")
tc <- textConnection(webpage)
readLines(tc)

require(httr)
url <- "https://companyname.sharepoint.com/folder1/folder2/Shared%20Documents/filename.csv"
r <- GET(url, authenticate("[email protected]","mypassword", type="any"))

library(readxl)
r <- read_excel('https://companyname.sharepoint.com/folder1/folder2/Shared%20Documents/filename.xlsx
', 'Sheet1', skip=1)

它们全都抛出403。唯一的例外是当我尝试第二个示例时，但type="ntlm"却抛出401错误。我真的很茫然。我究竟做错了什么？我已经三重检查以确保我的用户名和密码正确无误...我知道我可以将本地文件夹同步到Sharepoint并从那里读取，但是我当前的工作流程要求我直接从Sharepoint读取。

Answer 1

您在Windows上吗？如果是，请在资源管理器视图中打开该SharePoint网站，然后将其映射到驱动器。 K：驱动器，然后使用路径K：/ my SharePoint文件夹/myfile.txt读取文件。

Answer 2

这对我有用。请注意@SSL

之后添加的companyname.com

TEST <- readr::read_lines("//mysite.companyname.com@SSL/personal/my_username/Documents/Shared with Everyone/My_Test_File.txt")
TEST
