Why not just use wget.exe <url>. You can put that line in a batch file and run that through windows scheduler.
为什么不直接使用wget.exe <url>. 您可以将该行放在批处理文件中并通过 Windows 调度程序运行它。

The link the to document in Sharepoint should be a static URL. Use that URL in whatever solution you have to grab the file on your schedule.
Sharepoint 中指向文档的链接应该是静态 URL。在您必须按计划获取文件的任何解决方案中使用该 URL。

You can also do this:
你也可以这样做：
try
{
using (WebClient client = new WebClient())
{
client.Credentials = new NetworkCredential("username", "password", "DOMAIN");
client.DownloadFile(http_path, path);
}
}
catch (Exception ex)
{
MessageBox.Show("Error: " + ex.Message);
}

Yes it is possible to download the file from sharepoint. Once you have the url for the document, it can be downloaded using HttpWebRequest and HttpWebResponse.
是的，可以从 sharepoint 下载文件。获得文档的 url 后，就可以使用 HttpWebRequest 和 HttpWebResponse 下载它。
attaching a sample code
附上示例代码
DownLoadDocument(string strURL, string strFileName)
{
HttpWebRequest request;
HttpWebResponse response = null;
request = (HttpWebRequest)WebRequest.Create(strURL);
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.Timeout = 10000;
request.AllowWriteStreamBuffering = false;
response = (HttpWebResponse)request.GetResponse();
Stream s = response.GetResponseStream();
// Write to disk
if (!Directory.Exists(myDownLoads))
{
Directory.CreateDirectory(myDownLoads);
}
string aFilePath = myDownLoads + "\" + strFileName;
FileStream fs = new FileStream(aFilePath, FileMode.Create);
byte[] read = new byte[256];
int count = s.Read(read, 0, read.Length);
while (count > 0)
{
fs.Write(read, 0, count);
count = s.Read(read, 0, read.Length);
}
// Close everything
fs.Close();
s.Close();
response.Close();
}
You can also use the GetItem API of Copy service to download a file.
您还可以使用 Copy 服务的 GetItem API 来下载文件。
string aFileUrl = mySiteUrl + strFileName;
Copy aCopyService = new Copy();
aCopyService.UseDefaultCredentials = true;
byte[] aFileContents = null;
FieldInformation[] aFieldInfo;
aCopyService.GetItem(aFileUrl, out aFieldInfo, out aFileContents);
The file can be retrieved as a byte array.
该文件可以作为字节数组检索。
