C++程序中如何实现ftp多线程下载

本人不才,下面这个是从网络上转来的.不知可有帮助.

这是codeproject的关于ftp的实现，你可以去down源代码

Introduction

StuffFTP is a free for life FTP client. This FTP client will allow you to connect to FTP servers and upload and download files.

Motivation

Why did I create and continue to support StuffFTP? First it is a learning experience, and since I just got laid off from my company, I decided to use some of the tools they have provided, its legal as I technically bought them and they do not have other programmers following in my footstep nor do they plan on hiring any, to create something for the community. I also used another FTP program that was freeware for a while and then became pay to use software with little to no notice. That irked me and a friend suggested I create my own FTP client. So I am.

Progress

This is currently a work in progress and I would be the first to say there is a lot of work to do. Since I am laid off, I have lots of time on my hands. And this is an excellent chance for me to learn some of the concepts of C++ that I wanted to, but never had the chance while I was working. I was hoping to get a job in San Jose, CA, but decided to hold off and live on saving for a while.

Guarantee

I will support this program as best as I can. I have already setup a website and forum for it, here. I use the forum because I have trouble responding to email especially when I get a whole bunch of SPAM everyday. There is no adware or spyware in the program, and I guarantee that it will be free for the life of the program.

Some people have already asked why I don't open source the project. The main reason is I do not know if I can. StuffFTP uses some proprietary third party libraries. I do not know if I can post the source code or header files to those libraries. So everyone will have to wait until I can get rid of those libraries or hear back from the companies concerning my question about releasing header and associated help files.

Tools

* MS Windows XP Professional

* MS Visual Studio .NET C++/MFC

* Clickteam Install Maker

* Clickteam Patch Maker

* Betaone.net forum members

* CXListCtrl by Hans Dietrich

3rd Party Libraries

The application uses Catalyst Socket Tools Library Edition and Professional UI GUI library. So far the support has been fair with Prof-UI and outstanding with Catalyst. The Catalyst tool is for the actual FTP connection and, as the name suggests, Prof-UI is being used for the GUI.

Updates

You can find the latest updates here and you can also find my latest ramblings, blogs, and support here. This is where you can find out all the latest versions and information.

How to contribute

Money! Just kidding you can contribute by downloading, using, and giving feedback on the program. That way I can determine which path to take with the application and which features to prioritize or not. Graphics is also where I need lots of help. I am left brained and can not draw a good stick figure to save my life. If you can help with graphics or anything else, please let me know. Also talk to me, I am bored. I have no job at the moment so I can use the company.

Features

* Able to upload/download from server/computer

* Connect to FTP sites using login

* Connect using other ports besides 21

* Delete, rename, and CHMOD a file

History

* 12/10/2003 - Version 0.11a

* 12/07/2003 - Version 0.10a

FlashfXP只能单线程下载，可以先用FlashfXP登录FTP站点，选中你要下载的文件，右击鼠标，在出现的菜单上选择：“复制URL(Ctrl+U)”，FlashfXP会提示：“是否复制用户名及密码？”，选择“是”，然后打开迅雷，点“新建（Ctrl+N）”下载任务，在出现的界面上边：“网址（URL）”里面（Ctrl+V）填上刚刚粘贴的信息，这样迅雷就可以从你的FTP站点多线程下罩饥哪载文件了物码，而且你可以同时下载不同的文件，也是多线程的。当然，万一你的FTP站点是限制单线程下载的话肢拍，为了充分利用带宽，就只好同时下载其他文件来提高效率。万一你的FTP站点是限制每个IP只能单线程下载一份文件，这个办法可能就无能为力了。希望能帮到你，呵呵~~

ftp支持多线程同时下载 *** 作。因为ftp支持多线程同时下载 *** 作需要自己设计，在功能菜单中选择“站点属性”，接着取消属性窗口中巧基的“没有限制”选项并填入下载线程数目即可。所以ftp支持多坦带线程同时下载让宽芦 *** 作。
