swift之向ftp服务器传文件

在 mac 上如何使用 xcode, swift 语言开发一个向 ftp 服务器上传文件的工具？

使用的是第三方库 Rebekka，下载地址为：https://github.com/Constantine-Fry/rebekka。下载完之后直接将所有的 swift 文件拷到项目中即可使用。

下面是我自己写的代码 ，首先是 FtpManager.swift 类，封装了上传文件和创建文件夹的方法，代码如下：

public class FtpManager
{
    let m_host:String;
    let m_username:String;
    let m_password:String;
    let m_session:Session;

    init (host:String,username:String,password:String,passive:Bool)
    {
        m_host=host;
        m_username=username;
        m_password=password;

        var config=SessionConfiguration();
        config.host=host;
        config.username=username;
        config.password=password;
        config.passive=passive;

        m_session=Session(configuration: config);
    }

    public func UploadFile(srcPath:String,tarPath:String,callback:(Bool) -> Void)
    {
        let localPath=NSURL(fileURLWithPath: srcPath);

        m_session.upload(localPath, path: tarPath)
        {
            (succeed,error) -> Void in
            let fullUrl=self.m_host+tarPath;
            if succeed
            {
                print("Upload succeed!\nSource path: \(localPath)\nTarget url: \(fullUrl)\n");
            }
            else
            {
                print("Upload failed...\nError: \(error)\nSource path: \(localPath)\nTarget url: \(fullUrl)\n");
            }

            callback(succeed);
        };
    }

    public func CreateDirectory(path:String)
    {
        m_session.createDirectory(path)
        {
            (succeed, error) -> Void in
            let url=self.m_host+path;
            if succeed
            {
                print("Create directory succeed!\nUrl: \(url)\n");
            }
        }
    }
}

main.swift

此 mac 工具是被 unity3d 的一键打包工具调用的，思路是将 shell 命令写在一个文件中，在 c# 中执行此 shell 文件以打开此工具。

shell 命令为，&1 为工具路径，是c#传过来的值：

#！/bin/bash
open $

调用上面 shell 文件的 c# 代码为：

            if (!IsWindowSystem)
            {
                string rootPath = string.Format("{0}/Editor/BuildAssetBundle/Tools/", Application.dataPath.TrimEnd('/'));

                // save arguments to file
                string tempFilePath = rootPath + "MacFtpUploader_Arguments";
                File.WriteAllText(tempFilePath, sb.ToString());

                // invoke tool
                if (File.Exists(tempFilePath))
                {
                    string toolPath = rootPath + "MacFtpUploader";
                    string shell = string.Format("{0}MacFtpUploaderInvoker.sh {1}", rootPath, toolPath);
                    Process.Start("/bin/bash", shell);
                }
                else
                    throw new InvalidOperationException(string.Format("Save arguments to file {0} failed, reupload again please...", tempFilePath));
            }

运行结果为：
