HttpURLConnection.getInputStream very slow

由 坚强是说给别人听的谎言 提交于 2019-12-08 22:08:17
问题 HttpURLConnection.getInputStream takes very much time when compared to iPhone App which uses the same server side services. The following code is used for the service : date= new java.util.Date(); Log.d("time","Time Stamp before posting "+new Timestamp(date.getTime())); URL ur= new URL(url); HttpURLConnection conn = (HttpURLConnection) ur.openConnection(); conn.setRequestProperty("Connection", "close"); conn.setReadTimeout(10000); conn.setConnectTimeout(15000); conn.setRequestMethod("POST");

Java HttpURLConnection: Content Length computation

问题 I'm currently developing a library for the bitbucket issues RESTful API. I made good progress and now I'm going to tackle the section Updating an Issue which demands an HTTP PUT Request. Now I'm stuck because of the HTTP Error Code 411 Length Required . After a bit of googling, I found the following code example: // CORRECT: get a UTF-8 encoded byte array from the response // String and set the content-length to the length of the // resulting byte array. String response = [insert XML with UTF

HttpURLConnection getInputStream() has one second delay

由 心不动则不痛 提交于 2019-12-08 14:29:28
I am using HttpURLConnection for making POST requests. I observe always the same behaviour during tests: first request runs very fast (miliseconds) all following requests take one second + some miliseconds So something is causing 1 second delay. What can it be? The delay is happening exactly in HttpURLConnection#getInputStream(). I replaced the implementation with HttpClient - then everything is OK, no second delays (so it is not the server fault). But I really don't want to use any external dependency, so I would like to fix the HttpURLConnection thing... Any ideas? Below current

Single URLConnection to fetch only the first line in java using BufferedReader

由 非 Y 不嫁゛ 提交于 2019-12-08 12:46:03
问题 I am trying to write a Java program that should automatically download text from a website if and only if it gets updated. The problem I am running into is using only one HTTPURLConnection to do that because if i don't there will be billions of HTTPURLConnections to the web server since I am using a while(true) loop. Here is my work-in-progress, the getMsg() method receives a url and opens an HTTPURLConnection. Currently I am starting a new connection every time I have to read a line, which

How to get file properties without downloading

由 纵饮孤独 提交于 2019-12-08 09:37:13
问题 How to get file properties (e.g. date) without downloading file if I have URL of the file. I have to implement updates checker. For this purpose I'm going to compare dates of two files. One is local, the second is the same file but with latest date on server. I know URL to the second file. Please, give me a peace of advice - how to check date of the second file without downloading it? I have thought about comparing via hash, but I need to check whether file on server is latest version or not?

HttpURLConnection getResponseCode not returning

由 老子叫甜甜 提交于 2019-12-08 06:33:53
问题 I'm trying to POST a file to our server using HttpURLConnection on Android, but the getResponseCode call just hangs and never returns. The issue stems from the file being too big for the server, so the server sends back an HTTP error code of 413 (which I can see in the server logs), but on our device, it seems like this is never received. I have the following code in our app: public FileUploadUtility(URL requestURL, File uploadFile) throws IOException { file = uploadFile; String fileName =
