I have a MVC application and I'd like that each request must handle its own session.
My request:
CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
URL url = new URL("http://google.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
As we know CookieHandler allow just one session per application. I'd like that each request creates and use its own session.
Does anybody know how to do it?
Thanks
you will have to use Proxy while opening a connection...
the use of proxy provides always a new IP address for the server so you can be sure that the server maintains different session for each request...
your code will be something like following...
CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
URL url = new URL("http://google.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection(new Proxy("some_proxy"));

I used Jodd Http library to connect with the proxy:
ProxyInfo proxyInfoObj = new ProxyInfo(ProxyType.HTTP, "10.30.56.70", 8080, "", "");
SocketHttpConnectionProvider provider = new SocketHttpConnectionProvider();
provider.useProxy(proxyInfoObj);
HttpRequest request = HttpRequest.get(url);
request.method("GET");
request.charset("UTF-8");
HttpResponse response = request.open(provider).send();
result = response.bodyText();
But i got this error:
jodd.http.HttpException: HTTP: Invalid code
at jodd.http.net.HTTPProxySocketFactory.createHttpProxySocket(HTTPProxySocketFactory.java:113)
at jodd.http.net.HTTPProxySocketFactory.createSocket(HTTPProxySocketFactory.java:32)
If I use SOCKS4 type, the program hang and don't return anything. Can anyone help me?
But I can connect via proxy using following code:
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.30.56.70", 8080));
HttpURLConnection connection =(HttpURLConnection)new URL("http://tvl.csmtalk.vn/api/sms/receive").openConnection(proxy);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestProperty("Content-type", "text/xml");
connection.setRequestProperty("Accept", "text/xml, application/xml");
connection.setRequestMethod("GET");
connection.connect();
For me both codes hangs. When I try Jodd, it hangs because it can not open proxy socket to 10.30.56.70:8080. When I try to
telnet 10.30.56.70 8080
from command line it hangs as well. It looks like proxy is not responding. (You can contact Jodd support if you need more details, or if you want to send some private data regarding the connectivity.)
btw, you don't need to:
request.method("GET");
request.charset("UTF-8");
as method is already set to GET by method get() and charset is not used for requests, but response (to set one if not set by server).
I am trying to set Cookies and request headers via URL connection. Here is the client side code
UUID = request.getHeader("UUID");
conn.addRequestProperty("Cookie", iPlanetDirectoryPro);
conn = url.openConnection();
conn.setDoOutput(true);
objOstr = new OutputStreamWriter(conn.getOutputStream());
objOstr.write(res);
One server side i am trying a retrieve the cookie using "iPlanetDirectoryPro" as the cookie name. But i am getting null. What is the mistake i am doing here?
If i set as conn.addRequestProperty("iPlanetDirectoryPro", iPlanetDirectoryPro); then what is the difference between cookie-and-string-in-request-header https://stackoverflow.com/questions/21226475/difference-between-cookie-and-string-in-request-header
Try using:
conn.getRequestProperty("Cookies");
See the doc.
I have an Android app that need to set a requestproperty in a connection. Here is my code:
URL url = new URL(sUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("cookie", cookievalue);
connection.connect();
When I call the setRequestProperty method it launch the exception:
java.lang.IllegalStateException: Cannot set request property after connection is made
Is there a way to create the connection to the file without using the url.openConnection() ?
Here url.openCOnnection() will open new connection to the resource referred to by this URL.
Here you again opening a connection by calling url.connect() method. So remove that
Check this.. for the sample example...
You could try to use the CookieManager mentioned in http://developer.android.com/reference/java/net/HttpURLConnection.html
Set your cookie to CookieManager
CookieManager cookieManager = new CookieManager();
CookieHandler.setDefault(cookieManager);
HttpCookie cookie = new HttpCookie("lang", "fr");
cookie.setDomain("twitter.com");
cookie.setPath("/");
cookie.setVersion(0);
cookieManager.getCookieStore().add(new URI("http://twitter.com/"), cookie);
Source: http://developer.android.com/reference/java/net/HttpURLConnection.html
Use url.openConnection() after you set your cookie.
How to set tcp.nodelay for below given code:
URL url = new URL(urlText);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
As far as I am aware you cannot set tcp.noDelay on `HttpURLConnection' as this does not allow any interface to alter underlaying tcp socket.
What I can recommend is try using Apache http client as it provide mechanism to set multiple TCP options. Have a look at this DefaultHttpClient
Getting header fields from a URLConnection doesn't get session cookies for me.
When I use CookieManager I can get session cookies from a URL:
CookieManager manager = new CookieManager();
manager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(manager);
URLConnection con = url.openConnection();
con.getContent();
CookieStore cookieJar = manager.getCookieStore();
List<HttpCookie> cookies = cookieJar.getCookies();
This is fine, but I need to send a POST request. So I am writing to the URLConnection's output stream. My question is how to get the session cookies after sending the POST request.
Try using the same CookieManager object with your first and subsequent requests using URLConnection.
