京ICP备号-1 京公网安备02号有关FTP传输中 putfile（）的有关问题？ - VC/MFC当前位置:& &&&有关FTP传输中 putfile（）的有关问题？有关FTP传输中 putfile（）的有关问题？&&网友分享于：&&浏览：276次有关FTP传输中 putfile（）的问题？？描述： &
本人写了个ftp传输的CS程序； &
在使用putfile（）函数，如果给的文件名过长（达到230个字节的），则就会出现传输失败。 &
putfile 返回12031
的错误。 &
如果文件名的长度为200个字节一下就可以传输成功。------解决方案--------------------
没看到有说文件名长度有限制的，你的代码发出来看看吧
------解决方案--------------------
经验分享？
------解决方案--------------------
字符串过长导致问题这是有可能的问题时你有必要用那么长的文件名么而且一般操作Ftp还是建议通过socket直接连ftp服务器
------解决方案--------------------
直接在服务器上能建立那么长的名字的文件吗？
------解决方案--------------------
findfile 这个函数的参数是有字节数限制的，应该是260 个字节；
