如何解压缩由 PHP gzcompress() 函数压缩的字符串?
有完整的例子吗?
thx
我现在这样尝试:
public static String unzipString(String zippedText) throws Exception
{
ByteArrayInputStream bais = new ByteArrayInputStream(zippedText.getBytes("UTF-8"));
GZIPInputStream gzis = new GZIPInputStream(bais);
InputStreamReader reader = new InputStreamReader(gzis);
BufferedReader in = new BufferedReader(reader);
String unzipped = "";
while ((unzipped = in.readLine()) != null)
unzipped+=unzipped;
return unzipped;
}
但如果我尝试解压缩 PHP gzcompress (-ed) 字符串,它就不起作用。
PHP 的 gzcompress 使用 Zlib 而不是 GZIP
public static String unzipString(String zippedText) {
String unzipped = null;
try {
byte[] zbytes = zippedText.getBytes("ISO-8859-1");
// Add extra byte to array when Inflater is set to true
byte[] input = new byte[zbytes.length + 1];
System.arraycopy(zbytes, 0, input, 0, zbytes.length);
input[zbytes.length] = 0;
ByteArrayInputStream bin = new ByteArrayInputStream(input);
InflaterInputStream in = new InflaterInputStream(bin);
ByteArrayOutputStream bout = new ByteArrayOutputStream(512);
int b;
while ((b = in.read()) != -1) {
bout.write(b); }
bout.close();
unzipped = bout.toString();
}
catch (IOException io) { printIoError(io); }
return unzipped;
}
private static void printIoError(IOException io)
{
System.out.println("IO Exception: " + io.getMessage());
}
