<br />
1. 字符�~�码<br />
字符是以二进制编码的形式保存在存储器中的�Q�如�Q?#8220;�?#8221;�q�个字，可以用gbk的方式保�?用字节表�C�是[-50, -46])�Q�也可以用utf-8的方式保�?用字节表�C�是[-26, -120, -111])。程序在��d��数据块时需要一个字节一个字节的��d���Q�然后将字节转换为字�W�，昄���如果�E�序不知道字节是表示的什么编码的字符�Q�读出来��׃��出问题，�q�就如同你说了一句话�Q�我如果事先不知道你说的���是什么语�a��Q�就没法�?span class="t_tag" onclick="tagshow(event)" href="tag.php?name=%B7%AD%D2%EB">���译</span>了，如果你说�?span class="t_tag" onclick="tagshow(event)" href="tag.php?name=%D3%A2%D3%EF">��p��</span>�Q�我以�ؓ是日语，然后按日语的方式来理解到我的主观意识�Q�显然结果就是不知你在说什么了�Q�就成了我们�E�序中的��q��。所以对于前面我所表示的字节数�l�byte[] data = {-26, -120, -111},我们必须�q�样做才能得到正���的字符: String s = new String(data, "utf-8")�Q�（注：�q�里用了字符�Ԍ��因�ؓ字符串就是由一个个字符�l�成的）�Q�如果我们不指定参数里面�?utf-8"�Q�那么系�l�就会用<span id="wmqeeuq"    class="t_tag" onclick="tagshow(event)" href="tag.php?name=%B2%D9%D7%F7%CF%B5%CD%B3">操作�pȝ��</span>默认的编码了�Q�这可能是gbk或是什么�Q何编码�?br />
<br />
2. jsp服务器返回�ؕ码页�?br />
&nbsp;&nbsp;2.1 pageEncoding<br />
&nbsp;&nbsp;在jsp��面的page指��o中我们指定了pageEncoding属性，�q�个属性就是告诉jsp容器如何��d���q�个jsp��面�Q�所以这个属性必���M��jsp��面保存的编码保持一致。也���是��_��如果你页面的�~�码保存为gbk, 而pageEncoding讄���成了utf-8�Q�则jsp容器在读�q�个jsp��面的时候就会出�?如果存在非英文字�W�的�?。jsp容器读jsp的目的是���其���译成java代码�Q�所以如果读错了jsp��面�Q�翻译出来的java代码也就会出错，如果�q�种错误影响了java文�g的语法，��׃��在访问时出现无法�~�译jsp的语法错误，如果没有影响到语法，��׃��出现最�l�显�C�的html��面上有��q��的错误。所以如果遇到显�C�Zؕ码，则检查pageEncoding是否正确�?br />
&nbsp;&nbsp;2.2 contentType<br />
&nbsp;&nbsp;page指��o中的contentType属性用于指定返回给<span id="wmqeeuq"    class="t_tag" onclick="tagshow(event)" href="tag.php?name=%E4%AF%C0%C0%C6%F7">���览�?/span>的数据的文档�c�d���Q�服务器通过http头信息返回给���览器这个信息，所以在���览�?html代码中用��h��看不到的。同时contentType属性还可以指定��面的编码，��x��务器即以什么编码发送页面数据。比如说中文数据�Q�可以用gbk 或utf-8的方式来发送，�q�个�~�码跟jsp��面的编码没有关�p�，只要讑֮�的编码支持页面中的字�W�就行了。相同于有了一个字�W�串s="中国�?,然后�?s.getBytes("gbk")的方式来发送s。所以由于contentType错误出现��q��的概念不高，但也要注意一下，比如说如果设�|�成�?iso8859-1"�Q�则���览器就会显�C�Zؕ码了。contentType�q�有一个用�Q�就是浏览器���会依据�q�个�~�码来显�C�页面，在IE下点右键�Q�然后选择&#8220;�~�码&#8221;�Q�你���可以注意到��面是以什么编码显�C�的了�?br />
&nbsp;&nbsp;2.3 如果是servlet�q�回的结�?br />
&nbsp;&nbsp;上面说的是jsp�Q�如果servlet的话���p��注意讄���response.setCharacterEncoding(""),如果没有讄����Q�服务器会默认�ؓ是iso8859-1�Q�设�|�后得到的writer�Q�即response.getWriter()�Q�对象，��׃��依据�q�个�~�码来向客户端写数据�Q�writer对象的构造与以下方式�c�M���Q�PrintWriter pw = new PrinterWriter(new OutputStreamWriter(socket.getOutputStream(), "�~�码"))�Q�这里提��C��通过socket得到输出���，不明白的话可以参考我的另一���文章。pw.write("你好")�Q�实际上���是先通过byte[] data = "你好".getBytes("�~�码"),然后���data写给客户端�?br />
)<br />
<br />
3. 服务器得到客��L��传过来的数据��Zؕ�?br />
&nbsp;&nbsp;3.1 通用解决�Ҏ(gu��)��<br />
&nbsp;&nbsp;String param = request.getParameter("paramName")�Q�如果浏览器传过来的��Z��文，则取出来的数据将是�ؕ码。�ؓ什么呢�Q�因为客��L��只能���数据的�~�码传给服务器，如[-26, -120, -111]�Q�但服务器�ƈ不知道这是什么字�W�集的编码，于是假定为iso8859-1, 用这�U�方式构造了字符串s = new String(data, "iso8859-1")�Q�显然这栯���定是��q��。解��x��案很���单，我们得到值param后，用byte data[] = param.getBytes("iso8859-1"),�q�样data���是客户端传�q�来的真实编码，然后我们再重新创建字�W�串�Q�param = new String(data, "正确的编�?);<br />
&nbsp;&nbsp;3.2 POST��h��<br />
&nbsp;&nbsp;如于post��h��处理��h��更简单，get��h��与post��h��向服务器发送数据的方式不一��P��get��h��的参数是通过HTTP头信息中的第一行数据发送的�Q�是URI的一部分�Q�而post��h��则是在发送完HTTP头信息后作�ؓ单独的数据块发送的。因此对于get��h��的参敎ͼ�我们在��用request之前服务器已�l�读出来了，已经是�ؕ码了�Q�只能用前面的方案，但对于post��h��的数据，我们在调用getParameter或getReader之前�Q�服务器�q�没有去处理�Q�所以我们可以在getParameter之前先告诉服务器正确的编码，通过request.setCharacterEncoding("正确的编�?)�Q�然后再��d��参数�?br />
<br />
4 AJax<br />
&nbsp;&nbsp;对于ajax��h��注意要用utf-8�~�码�Q�request和response都需要��用utf-8
