I'm trying to make a HTTPS post request. String url = "https://myhttpsurl.com" URL myurl = new URL(url); HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection(); con.setRequestMethod("POST"); String query = "confirmation_number=" + URLEncoder.encode(confNumber, "UTF-8"); con.setRequestProperty("Content-length"

问题 I am trying to use get request on site with REST API. However the link to acces it is an IP address and I am getting the No subject alternative names matching IP address error. When I use the same exact link in browser, it works. How can I solve this issue? Below is my code: public static void main(String[] args) { System.getProperties().put( "proxySet", "true" ); System.getProperties().put( "socksProxyHost", "xxx.xxx.xxx.xxx" ); System.getProperties().put( "socksProxyPort", "xxxx" ); URL

问题 I try to parse information from website. However, It works only when the context is not very long. As the Html goes large, the content loaded is incomplete. The total length of the retrieved String is around 40000. The count of the string retrieved each time is different. (ex: That is like 31345 count for the first time and 31358 next time) So I can not retrieve full page. As the result, I assume this problem could be related to internet connection or buffer. But I have used the

问题 I've been pulling my hair trying to figure this out: I'm making an HttpsURLConnection and using java.net.cookiemanager to manage my cookies (there's no way of using android.webkit.cookiemanager to HttpUrlConnection/HttpsUrlConnection as I have understood?). I need to save my longtime cookie to later connections. Sadly I can't use http://loopj.com/android-async-http/ and it's PersistentCookieStore because I need to allow an untrusted certificate (using http://abhinavasblog.blogspot.se/2011/07

问题 I am trying to login to twitter using this code below: //private final String USER_AGENT = "Mozilla/5.0"; private final String USER_AGENT = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36"; public static void main(String[] args) throws Exception { runThisClass("This is a samplest tweet234!"); } public static void runThisClass(String tweet)throws Exception{ String url = "https://mobile.twitter.com/session/new"; String url2 = "https

问题 Long story short. I want to download some google sheet files from the internet when my App starts. Here's the situation: Newer Devices: Everything works 100%, no problems, all files downloaded. Older Devices (API 16-17): Downloads first sheet file correctly. Fails to download the second file. I get a HTTP/1.1 302 Moved Temporarily problem and file fails to download itself correctly. I call AsynchTask for both files. AsynchTask runs perfectly and I tried other methods to see if AsynchTask was

问题 I know this subject is discussed in many places, but after I went through almost all of them, I have decided to create my first StackOverflow question... The problem is the following: I want to connect to a secured webservice (https) that use a certificate to restrict the access, and a username/password to authenticate the user. So i have a client cert (p12 file) and a server cert (pem or der file). I try to use the HttpURLConnection class, because from what I've heard, Apache library will no

问题 I am trying to do a POST request using HttpsURLConnection , and get java.net.ProtocolException: Connection already established on setRequestMethod Weirdly, conn.connected returns false just before.

问题 I am developing a java agent to monitor http communications happening in my application server. I like to know the SSL version(SSLv3, TLS, etc) used in outgoing Https connections. Is there a way to get the SSL version by any means? 回答1: I used this solution, maybe it can help you: First you need an extension class of SSLSocketFactory to attach a HandshakeCompletedListener to the sockets created by the SSLSocketFactory : (inspired by How to override the cipherlist sent to the server by Android
