• 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_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!
    Source path: (localPath)
    Target url: (fullUrl)
    ");
                }
                else
                {
                    print("Upload failed...
    Error: (error)

    ");
                }
                
                callback(succeed);
            };
        }
        
        public func CreateDirectory(path:String)
        {
            m_session.createDirectory(path)
            {

        }
    }

    190 Main();
    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 $1

    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));
                }
    View Code

    运行结果为:
