背景介绍
因为一直在处理restful API，给移动端提供的数据需要考虑流量问题，优先考虑就是压缩现有的字符串，然后再考虑业务逻辑方面的减少流量。鉴于找这些资料也花了不少时间，所以整理了这篇文章，留作纪念。

javascript的压缩与解压

代码具体实现
PHP (>=5.4)
[php] view plain copy
$srcString="1";
$srcCompress=base64_encode(gzencode($srcString,9));
echo strlen($srcCompress).'---压缩后字符串长度
';
$newString=base64_decode($srcCompress);
$newString=gzdecode($newString);
echo $newString.'----解压后原字符串
';
c#
(建议还是考虑各个平台的，PCL版本下的见前面的网址，但是没调试通过)
[csharp] view plain copy
using System.IO.Compression;
using System.Text;
public string Compress (string text)
{
byte[] buffer = Encoding.UTF8.GetBytes (text);
using (MemoryStream ms = new MemoryStream ()) {
GZipStream Compress = new GZipStream (ms, CompressionMode.Compress);
Compress.Write (buffer, 0, buffer.Length);
Compress.Close ();
return Convert.ToBase64String (ms.ToArray ());
}
}
public string Decompress (string text)
{
byte[] buffer = Convert.FromBase64String (text);
using (MemoryStream tempMs = new MemoryStream ()) {
using (MemoryStream ms = new MemoryStream (buffer)) {
GZipStream Decompress = new GZipStream (ms, CompressionMode.Decompress);
Decompress.CopyTo (tempMs);
Decompress.Close ();
return Encoding.UTF8.GetString (tempMs.ToArray ());
}
}
}
