如何转义 java 中的“@”字符
How to escape '@' character in java
我正在编写一个方法来建立与 FTP 的连接，并且在配置 URL 时，我的密码包含“@”字符，这与主机名冲突。如何解决？这个字符可以转义吗？
URL: ftp://xyz:abc@27@www.sezin.com/home/pk09
强烈劝你不要这样做。引用 （以防它被清理）：
Auth information in the URL was deprecated years ago and implementors in various realms (browsers, for instance) are actively removing it, as it's ridiculously insecure. Surely there's a way to connect to your FTP server and then supply the auth info (which is still ridiculously insecure -- this is FTP -- but may at least be supported).
但是 user information in the authority section of a URL（已弃用）是百分比编码的，因此：
ftp://xyz:abc%4027@www.sezin.com/home/pk09
%40 是 @ 的百分比编码值。
