问题 I'm using the new java.net.http classes to handle asynchronous HTTP request+response exchanges, and I'm trying to find a way to have the BodySubscriber handle different encoding types such as gzip. However, mapping a BodySubsriber<InputStream> so that the underlying stream is wrapped by a GZIPInputStream (when "Content-Encoding: gzip" is found in the response header) leads to a hang. No exceptions, just a total cessation of activity. The code which maps the BodySubscriber looks like this:

问题 How can i decompress a String that was zipped by PHP gzcompress() function? Any full examples? thx I tried it now like this: 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

问题 I have some large base64 encoded data (stored in snappy files in the hadoop filesystem). This data was originally gzipped text data. I need to be able to read chunks of this encoded data, decode it, and then flush it to a GZIPOutputStream. Any ideas on how I could do this instead of loading the whole base64 data into an array and calling Base64.decodeBase64(byte[]) ? Am I right if I read the characters till the '\r\n' delimiter and decode it line by line? e.g. : for (int i = 0; i < byteData

问题 Are there any GZIPInputStream implementation for J2ME available. I would prefer an Apache Style License 回答1: IIRC the phoneME project includes an implementation of GZIPInputStream. I'm not sure of the licensing but it might be worth a look. 回答2: TinyLine implementation should be OK also for commercial usages. 回答3: You may want to try: http://code.google.com/p/compress-j2me Library is only 6.5k big. 来源： https://stackoverflow.com/questions/1426154/gzipinputstream-implementation-for-j2me

问题 Question See updated question in edit section below I'm trying to decompress large (~300M) GZIPed files from Amazon S3 on the fly using GZIPInputStream but it only outputs a portion of the file; however, if I download to the filesystem before decompression then GZIPInputStream will decompress the entire file. How can I get GZIPInputStream to decompress the entire HTTPInputStream and not just the first part of it? What I've Tried see update in the edit section below I suspected a HTTP problem

问题 I have a static helper method responsible for getting a compressed JSON string from our Rails application, and decompressing the data before returning a String representation. I wrote two JUnit tests that, one that tests that the JSON parses correctly, and another more basic test that determines whether a string of length greater than zero is returned from the server. The problem: When I run the test suite, the first test method succeeds properly, and the other fails with an IOException and

问题 Does anyone know if this bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=2192186 has been resolved yet? It is causing issues on our side in data collection from archive or archives. Looks like this is a very old issue: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4691425 If it is resolved, please let me know jvm version that contains the fix. 回答1: I check it again and released that bug is already fixed (check its status and resolution fields).
