APP端压缩上传，与PHP端解压实现

一、android与php的交互

java

文件先转化成二进制，再压缩成字节数组，之后base64转化成字符串用于json传输

String body = "Lorem ipsum shizzle ma nizle";

   URL url = new URL("http://some.url/file.php?id=" + uid);
   URLConnection conn = url.openConnection();
   conn.setDoOutput(true);
   conn.setRequestProperty("Content-encoding", "deflate");
   conn.setRequestProperty("Content-type", "application/octet-stream");

   DeflaterOutputStream dos = new DeflaterOutputStream(conn.getOutputStream());

   dos.write(body.getBytes());
   dos.flush();
   dos.close();

php

$content = http_get_request_body();

$uncontent = gzuncompress($content);

二、ios与php的交互

php接收gzip压缩

gzdecode(base64_decode($json));//ios gzip uncompress

php接收zlib压缩

gzuncompress(base64_decode($json));//ios zlib uncompress
