serialization - Java - Invalid stream header -


i working on networking java , having issue converting object byte array, splitting array 2 parts, sending each on tcp stream, receiving it, reconstructing byte array, , reforming object.

so far working. have except reconstruction of object. error when using objectinputstream:

java.io.streamcorruptedexception: invalid stream header: 34323435

which common error see online. have tried fixing it. 1 of causes i've heard of stream not flushed after sending bytes, code flus steam before sending it. code send data is:

 public void sendtcp(objectoutputstream tcpout) {     try {         synchronized(tcpout) {             tcpout.write(data);             tcpout.flush();         }     } catch (ioexception e) {         e.printstacktrace();     } }

and able read bytes on server side. problem comes when combining bytes together. once done use recreate object:

bytearrayinputstream in = new bytearrayinputstream(data); objectinputstream = new objectinputstream(in); object object = is.readobject(); is.close(); in.close();

but error gets thrown on objectinputstream line. have looked @ raw data debugging , matches up. bytes of object, before split , sent, matches bytes recombined after received. i've been stuck on little while , helpful if help.

i having issue converting object byte array, splitting array 2 parts, sending each on tcp stream, receiving it, reconstructing byte array, , reforming object.

of course are. it's pointless. there's fluffing around here. you're over-complicating , making mistakes in process. don't need of this. it's waste of time , space. tcp splitting segments; ip splitting packets, , routers splitting fragments. don't need add layer of that.

  • get rid of bytearrayoutputstream , bytearrayinputstream
  • create 1 objectoutputstream , 1 objectinputstream, in order, wrapped around socket output , input streams respectively, @ both ends, , keep them life of socket
  • use writeobject() , readobject() directly on these object streams
  • don't use other streams or readers or writers on same socket.

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
