问题 I have some typical codes which used HttpURLConnection to get a file with an URL. They worked fine in android 1.x and 2.x. But failed in Android 4.1! I searched on the web but found little similar information. Would anybody please help to investigate this issue? private String mURLStr; private HttpURLConnection mHttpConnection; ... url = new URL(mURLStr); ... mHttpConnection = (HttpURLConnection) url.openConnection(); mHttpConnection.setDoOutput(true); mHttpConnection.setRequestMethod("GET");

HttpURLConnection PUT to Google Cloud Storage giving error 403

由 时间秒杀一切 提交于 2019-12-10 02:06:43
问题 I tried to upload a file to Google Cloud Storage using XML API. I have the right GoogleAccessId, expiry date and signature generated for each upload. The strange thing is that I can PUT file using Postman (application for Chrome), so I'm sure that the URL is ok. I just cannot PUT it using my Android Java program (it returns to me 403 error). The source code performing upload is here (it base on this one: https://cloud.google.com/storage/docs/access-control#Signing-Strings): URL url;

Java, HttpURLConnection and setting the content length

由 拜拜、爱过 提交于 2019-12-09 14:38:19
问题 I'm setting the length of the content in my HttpURLConnection, for a PUT. urlConnection.setRequestProperty("Content-Length", "" + responseJSONArray.toString(2).getBytes("UTF8").length); The actual number of bytes is 74. However, when I query the content length of urlConnection I'm returned -1 . Why is that? And why are lengths not equal (given that I set this)? I must set the content-length because I'm receiving a 411 response from the server. (Also, in the Sun examples I've seen the second

HTTP responses with code 3xx and empty 'Location' header

由 回眸只為那壹抹淺笑 提交于 2019-12-09 03:46:23
问题 I'm connecting to URLs with Java ( HttpURLConnection ). I have noticed that in some cases, the response code is 3xx but the 'Location' header is empty. How does a client browser know where to redirect after receiving this kind of HTTP response? Thanks 回答1: Not all 3xx replies can redirect automatically. 300 provides multiple URLs in the response body, not in the Location header. The client/user has to decide which one to retrieve next. 301 , 302 , 303 , and 307 provide a Location only if the

Posting a large file in Android

问题 I sometimes get an OutOfMemoryError when posting a large file in Android. This is the code I'm using. Am I doing something wrong? HttpURLConnection con = (HttpURLConnection) url.openConnection(); con.setRequestMethod("POST"); con.setDoInput(true); con.setDoOutput(true); ostream = new DataOutputStream(con.getOutputStream()); byte[] buffer = new byte[1536]; int count; while ((count = fileInput.read(buffer)) != -1) { ostream.write(buffer, 0, count); // This sometimes causes OutOfMemoryError }
