ftp源代码下载

❷ 怎么样才可以把网站的源代码下载下来

首先，源代码有两个概念。
解析前的源代码，如ASP/php/ASPX等
解析后的源代码，即HTML代码
如果是别人的网站，解析前的代码一般是弄不到的。
目前所有网站都可以通过浏览器中的查看源代码功能查看。
如果是自己的网站，那么可以上FTP或者在线文件管理系统下载源代码或远程控制管理服务器

❸ 求FTP Server和FTP Client的源代码，要java或C++的,

客户端

- connect to server and request service
- send size-of-sile info to server
- start receiving file from server
- close connection

❹ 如何把腾讯云服务器上的源代码下载

可以通过服务器或小插件下载。
如果搭建了ftp服务可以通过ftp，如果只有ssh连接也可以在线安装一些小插件下载。
腾讯云云服务器是在云中提供可扩展的计算服务，功能非常强大。

❺ FTP下载下来是网站的源代码对吗

是的，FTP下载的就是网站源代码，但有的网站还有MSSQL或者MYSQL数据库，这个一般下载不到，即使下载到，重新上传上去路径不一定对，数据库名，用户名，密码也不一定对。

❻ 能否给一个java开发的具有图形界面的ftp服务器客户端源代码呢

❼ 如何把ftp上的源代码下载下来

这个简单，在网站根目录上一级建个文件夹，把选择网站根目录后点复制，然后粘贴到新建的文件夹里面，把文件在里面压缩一下，压缩好后，点击压缩文件就会下载了。

下面wwwroot就是下载的压缩好的源码

❽ 别人帮我把网站做好了，可是网站的源代码我不知道 ，我进我的网站的FTP里面 可以找到并下载吗

asp和php做的网站可以，因为这两种开发语言是开源的 。直接到ftp里面把所有文件下载到本地就可以了。
如果是asp.net或者是jsp开发的话 那么就要找做网站的人要源码了 。

PS：asp开发的网站文件后缀是.asp。 php开发的网站文件后缀是.php 。asp.net开发的网站后缀一般为aspx

Good Luck

❾ 如何用ftp下载已上传的网站的源代码进行修改

首先你需要知道如下参数：对方的 FTP 服务器的 IP 地址、用户名、登录密码、对外公用的子目录和对该目录的读写权限、以及对外服务的 FTP 端口号（不一定都是标准的端口号）。然后你用 cuteftp、leapftp 等客户端软件，在其中设置好以上参数，就可以下载网站的源代码了。（现在的 FTP 客户端都支持文件和子目录的递归下载）

❿ 网站远程服务器 怎么下载源代码

最简单的，直接打开ftp://网站IP地址，用户名，密码就可复制。
最好用FTP工具上传下载，如leapftp等。
