java - Stream closed when using htpp client -

-

when using httpclient response error on line out.write(entityutils.tostring(resentity)); // line 70 in java code

why happens?

    closeablehttpclient httpclient = httpclients.custom().setuseragent("mozilla/5.0 (windows nt 6.3; rv:36.0) gecko/20100101 firefox/36.0").build();     httpresponse response = httpclient.execute(new httpget(searchlink.tostring()));       httpentity resentity = response.getentity();     system.out.println(entityutils.tostring(resentity));     printwriter out = new printwriter(new file("searchresult.xml"));     out.write(entityutils.tostring(resentity));     out.flush();     out.close();     httpclient.close();

the error is

2015/08/07 13:03:12,887 error [stderr] (thread-101) java.io.ioexception: stream closed 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ java.util.zip.gzipinputstream.ensureopen(gzipinputstream.java:61) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ java.util.zip.gzipinputstream.read(gzipinputstream.java:112) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ org.apache.http.client.entity.lazydecompressinginputstream.read(lazydecompressinginputstream.java:74) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ sun.nio.cs.streamdecoder.readbytes(streamdecoder.java:283) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ sun.nio.cs.streamdecoder.implread(streamdecoder.java:325) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ sun.nio.cs.streamdecoder.read(streamdecoder.java:177) 2015/08/07 13:03:12,887 error [stderr] (thread-101)     @ java.io.inputstreamreader.read(inputstreamreader.java:184) 2015/08/07 13:03:12,888 error [stderr] (thread-101)     @ java.io.reader.read(reader.java:140) 2015/08/07 13:03:12,888 error [stderr] (thread-101)     @ org.apache.http.util.entityutils.tostring(entityutils.java:244) 2015/08/07 13:03:12,888 error [stderr] (thread-101)     @ org.apache.http.util.entityutils.tostring(entityutils.java:288) 2015/08/07 13:03:12,888 error [stderr] (thread-101)     @ mainthread.search.dorequest(search.java:70) 2015/08/07 13:03:12,888 error [stderr] (thread-101)     @ mainthread.search.search(search.java:29) ...

at same time response request recieved on line

system.out.println(entityutils.tostring(resentity));

you can't read response stream twice, doing invoking entityutils.tostring(resentity) twice.

system.out.println(entityutils.tostring(resentity)); // once // ... out.write(entityutils.tostring(resentity)); // twice

by time 2nd time, response stream has no more data read.

in case, make sure read response stream once assigning resulting string variable. can safely use string variable many times like.

string resentitytostring = entityutils.tostring(resentity); system.out.println(resentitytostring); // ... out.write(resentitytostring);

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana
