我有與json webservice連接的大問題。我想從服務器獲取gzipped數據。 以下是我的代碼。問題是當我解析響應我正在接受gzip編碼和我得到gzipped數據，我讀這條數據線一切看起來不錯，然後application throw EOFException，出了什麼問題？ 我認爲如果我可以讀取gzipped數據的某些部分，服務器響應是很好的。我會感謝任何幫助:)。Java和JSON響應EOFException
HttpPost httppost = new HttpPost(requestUrl);
httppost.addHeader("Accept-Encoding", "gzip");
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
inputStream = entity.getContent();
contentEncoding = response.getFirstHeader("Content-Encoding");
}
private String convertResponseToString() throws IOException {
GZIPInputStream zis = null;
if (contentEncoding != null
&& contentEncoding.getValue().equalsIgnoreCase("gzip")) {
GZIPInputStream gzipStream = new GZIPInputStream(inputStream);
if (true) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] buf = new byte[256];
int len;
while ((len = gzipStream.read(buf, 0, 256)) > 0) {
bos.write(buf, 0, len);
}
bos.flush();
buf = bos.toByteArray();
inputStream.close();
inputStream = new ByteArrayInputStream(buf);
}
}

我猜測HttpClient的照顧了數據提取的你了。 – nhahtdh
