如今,Cake 中没有任何内置功能提供使用 FTP 协议传输文件的功能。
尽管如果您在“Full CLR”上运行 Cake,您可以使用内置的 .NET 框架FtpWebRequest来上传文件。如果您正在FtpWebRequest运行..NET CoreCake.CoreCLR
一种方法是创建ftp.cake一个静态FTPUpload实用程序方法,您可以从build.cake文件中重用该方法。
示例 ftp.cake
public static bool FTPUpload(
ICakeContext context,
string ftpUri,
string user,
string password,
FilePath filePath,
out string uploadResponseStatus
)
{
if (context==null)
{
throw new ArgumentNullException("context");
}
if (string.IsNullOrEmpty(ftpUri))
{
throw new ArgumentNullException("ftpUri");
}
if (string.IsNullOrEmpty(user))
{
throw new ArgumentNullException("user");
}
if (string.IsNullOrEmpty(password))
{
throw new ArgumentNullException("password");
}
if (filePath==null)
{
throw new ArgumentNullException("filePath");
}
if (!context.FileSystem.Exist(filePath))
{
throw new System.IO.FileNotFoundException("Source file not found.", filePath.FullPath);
}
uploadResponseStatus = null;
var ftpFullPath = string.Format(
"{0}/{1}",
ftpUri.TrimEnd('/'),
filePath.GetFilename()
);
var ftpUpload = System.Net.WebRequest.Create(ftpFullPath) as System.Net.FtpWebRequest;
if (ftpUpload == null)
{
uploadResponseStatus = "Failed to create web request";
return false;
}
ftpUpload.Credentials = new System.Net.NetworkCredential(user, password);
ftpUpload.KeepAlive = false;
ftpUpload.UseBinary = true;
ftpUpload.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
using (System.IO.Stream
sourceStream = context.FileSystem.GetFile(filePath).OpenRead(),
uploadStream = ftpUpload.GetRequestStream())
{
sourceStream.CopyTo(uploadStream);
uploadStream.Close();
}
var uploadResponse = (System.Net.FtpWebResponse)ftpUpload.GetResponse();
uploadResponseStatus = (uploadResponse.StatusDescription ?? string.Empty).Trim().ToUpper();
uploadResponse.Close();
return uploadResponseStatus.Contains("TRANSFER COMPLETE") ||
uploadResponseStatus.Contains("FILE RECEIVE OK");
}
示例用法 build.cake
#load "ftp.cake"
string ftpPath = "ftp://ftp.server.com/test";
string ftpUser = "john";
string ftpPassword = "top!secret";
FilePath sourceFile = File("./data.zip");
Information("Uploading to upload {0} to {1}...", sourceFile, ftpPath);
string uploadResponseStatus;
if (!FTPUpload(
Context,
ftpPath,
ftpUser,
ftpPassword,
sourceFile,
out uploadResponseStatus
))
{
throw new Exception(string.Format(
"Failed to upload {0} to {1} ({2})",
sourceFile,
ftpPath,
uploadResponseStatus));
}
Information("Successfully uploaded file ({0})", uploadResponseStatus);
示例输出
Uploading to upload log.cake to ftp://ftp.server.com/test...
Successfully uploaded file (226 TRANSFER COMPLETE.)
FtpWebRequest是非常基本的,所以你可能需要调整它以适应你的目标 ftp 服务器,但上面应该是一个很好的起点。

虽然我自己没有尝试过,但我“认为”我说你可以使用这个Cake Addin进行文件传输操作是对的。绝对值得与插件的原作者谈谈。
如果没有,您最好为 Cake 创建一个自定义插件,以提供您正在寻找的功能。
有一个问题是,这是否也应该成为 Cake 的核心功能集,但是,第一个行动方案将是一个插件。
