使用R将文件保存到Sharepoint

可以通过以下步骤实现：

1. 安装必要的R包：首先，需要安装并加载以下R包：httr、RCurl和XML。可以使用以下命令进行安装：install.packages(c("httr", "RCurl", "XML")) library(httr) library(RCurl) library(XML)
2. 获取Sharepoint访问令牌：为了与Sharepoint进行交互，需要获取访问令牌。可以使用以下代码获取访问令牌：site_url <- "https://your-sharepoint-site-url" username <- "your-username" password <- "your-password" token_url <- paste0(site_url, "/_api/contextinfo") response <- POST(token_url, authenticate(username, password, "ntlm"), verbose()) token <- content(response)$d$GetContextWebInformation$FormDigestValue
3. 上传文件到Sharepoint：使用以下代码将文件上传到Sharepoint：file_path <- "path-to-your-file" upload_url <- paste0(site_url, "/_api/web/GetFolderByServerRelativeUrl('/Shared Documents')/Files/add(url='", basename(file_path), "',overwrite=true)") file_content <- readBin(file_path, "raw", file.info(file_path)$size) headers <- c("Content-Type" = "application/octet-stream", "X-RequestDigest" = token) response <- POST(upload_url, body = file_content, authenticate(username, password, "ntlm"), add_headers(.headers=headers), verbose())

在上述代码中，site_url是Sharepoint站点的URL，username和password是用于访问Sharepoint的凭据。file_path是要上传的文件的本地路径。

1. 验证文件上传：可以使用以下代码验证文件是否成功上传到Sharepoint：file_info_url <- paste0(site_url, "/_api/web/GetFileByServerRelativeUrl('/Shared Documents/", basename(file_path), "')") response <- GET(file_info_url, authenticate(username, password, "ntlm"), verbose()) file_info <- content(response)

以上步骤将文件成功保存到Sharepoint。请注意，这只是一个基本的示例，具体的实现可能因为Sharepoint版本和配置的不同而有所差异。
