<b>urlencoder</b><dt>extends <a href="../../java/lang/object.html" title="class in java.lang">object</a></dl> <p> utility class for html form encoding. this class contains static methods for converting a string to the <code>application/x-www-form-urlencoded</code> mime format. for more information about html form encoding, consult the html <a href="specificationhttp://www.w3.org/tr/html4/">specification</a>. 用于html表单编码的工具类，这个类含有将字符串编码为application/x-www-form-urlencoded这样 mime格式的方法。关于html表单编码的更多细节，查阅html规范。 <p> when encoding a string, the following rules apply: 当对字符串编码时，遵循以下规则： <p> <ul> <li>the alphanumeric characters "<code>a</code>" through "<code>z</code>", "<code>a</code>" through "<code>z</code>" and "<code>0</code>" through "<code>9</code>" remain the same. 字母数字的字符，a-z，a-z，0-9保持不变。 <li>the special characters "<code>.</code>", "<code>-</code>", "<code></code>", and "<code>_</code>" remain the same. 特别字符.，-，和_保持不变。 <li>the space character "<code> </code>" is converted into a plus sign "<code>+</code>". 空格字符被转换成+号。 <li>all other characters are unsafe and are first converted into one or more bytes using some encoding scheme. then each byte is represented by the 3-character string "<code>%<i>xy</i></code>", where <i>xy</i> is the two-digit hexadecimal representation of the byte. the recommended encoding scheme to use is utf-8. however, for compatibility reasons, if an encoding is not specified, then the default encoding of the platform is used. 其他所有的字符都是不安全的，首先按照编码规范转换成一个或更多的字节。每一个字节被表示成 3字符的字符串%xy。xy是该字节的两个十六进制位表示，推荐的编码规范是utf-8。然而，出于兼容性考虑，如果编码没有被指定，那么默认平台所使用的编码。 </ul> <p> for example using utf-8 as the encoding scheme the string "the string ü@foo-bar" would get converted to "the+string+%c3%bc%40foo-bar" because in utf-8 the character ü is encoded as two bytes c3 (hex) and bc (hex), and the character @ is encoded as one byte 40 (hex). 以utf-8编码举例，字符串“the string ü@foo-bar”将被转换成“the+string+%c3%bc%40foo-bar”，因为在utf-8中，字符ü被编码成c3(16进制)和bc(16进制)，字符@被编码成一个字节40(16进制)。 <p> <p> <dl> <dt><b>since:</b></dt> <dd>jdk1.0</dd> </dl> <hr> <p> <!-- ======== nested class
