由 ╄→гoц情女王★ 提交于 2019-12-06 11:17:38
is there any way to reset the connection,so that i can read from starting of the document? It is a slow process that reconnecting to read from sarting,i want to read a file 20 times per second through http,is there any other way to do this? URLConnection is an easy but somewhat "dumb" class. I can suggest you to do it the Java way: instantiate a new URLConnection. ;) Java is not really a language that encorages reusage of objects. You can try resetting the input stream, see the docs for more info, but I don't think it will do another GET. Who knows how the concrete implementation behind

Google App Engine ( Java ) : URL Fetch Response too large problems

由 青春壹個敷衍的年華 提交于 2019-12-06 10:44:39
问题 I'm trying to build some sort of webservice on google apps. Now the problem is, I need to get data from a website (HTML Scraping).

Switching from WiFi connection to 3g causes connection to hang?

由 一曲冷凌霜 提交于 2019-12-06 00:58:12
I have an application which connects to a web service. I can connect to the web service any number of times without any problem using WIFI or 3G provided that I stay loyal to my connection type during the life cycle of my application. That is if I don't switch from WIFI to 3G. If I switches from WIFI to 3G, I can't get a response anymore. My connection just keeps on waiting for response. I tried 4 scenarios below. I'm only having problem with the 3rd scenario. What could be the problem? 1st Scenario: Connection is always on WIFI (Ok) Application connects to a web service using WIFI. Response

使用Fiddler监听Java HttpURLConnection请求的小技巧

由 旧时模样 提交于 2019-12-06 00:55:19
参考资料 默认情况下Fiddler是不能监听Java HttpURLConnection上的HTTP请求的。原因容易理解，Fiddler能监听浏览器的HTTP请求是因为它启动一个代理服务器，浏览器通过这个代理服务器上网，但HttpURLConnection默认不使用该代理。 Fiddler 官方给出的解决方法是启动Java程序时设置代理，例如： java -DproxySet=true -DproxyHost=127.0.0.1 -DproxyPort=8888 Main2 stackoverflow 上有人提供了另一种方法： // set http proxy System.setProperty("http.proxyHost", "localhost"); System.setProperty("http.proxyPort", "8888"); // set https proxy System.setProperty("https.proxyHost", "localhost"); System.setProperty("https.proxyPort", "8888"); 使用以下代码访问 http://www.163.com/ 测试，以上两种方法都可行 public class Main2 { public static void main(String[] args
