go - golang and python thrift communcation -


i using thrift. here thrift file:

namespace py hello namespace go hello  service hello{      string hellostring(1:string para)  }

and generate python , golang code

thrift -gen py hello.thrift thrift -gen go hello.thrift

python server code: py-server.py

import socket import sys sys.path.append('./gen-py/')  hello import hello hello.ttypes import *  thrift.transport import tsocket thrift.transport import ttransport thrift.protocol import tbinaryprotocol thrift.server import tserver  class hellohandler:     def hellostring(self, msg):         ret = "hellostring received: " + msg         print ret         return msg   handler = hellohandler() processor = hello.processor(handler) transport = tsocket.tserversocket("127.0.0.1", 19090) tfactory = ttransport.tbufferedtransportfactory() pfactory = tbinaryprotocol.tbinaryprotocolfactory()  server = tserver.tsimpleserver(processor, transport, tfactory, pfactory)  print "starting thrift server in python..." server.serve()

and can run well:

$ python py-server.py  starting thrift server in python...

and client writen golang, go-client.go:

package main  import (     "./gen-go/hello"     "fmt"     "git.apache.org/thrift.git/lib/go/thrift"     "net"     "os" )  func main() {     transportfactory := thrift.newtframedtransportfactory(thrift.newttransportfactory())     protocolfactory := thrift.newtbinaryprotocolfactorydefault()     transport, err := thrift.newtsocket(net.joinhostport("127.0.0.1", "19090"))     fmt.println(1)     if err != nil {         fmt.fprintln(os.stderr, "error resolving address:", err)         os.exit(1)     }     usetransport := transportfactory.gettransport(transport)     client := hello.newhelloclientfactory(usetransport, protocolfactory)     fmt.println(2)     if err := transport.open(); err != nil {         fmt.println(3)         fmt.fprintln(os.stderr, "localhsot:19090", " ", err)         os.exit(1)     }     defer transport.close()     fmt.println(4)     r1, e1 := client.hellostring("lalalalalalalallalaal")     fmt.println(5)     fmt.println("call->", r1, e1) }

but can't run, output, , can not stop normally

$ go run go-client.go  1 2 4

and server not receive message.

is there problem in golang code?

if write client python , can run well..

import socket import sys sys.path.append('./gen-py/')  hello import hello thrift import thrift thrift.transport import tsocket thrift.transport import ttransport thrift.protocol import tbinaryprotocol  try:     transport = tsocket.tsocket('127.0.0.1', 19090)     transport = ttransport.tbufferedtransport(transport)     protocol = tbinaryprotocol.tbinaryprotocol(transport)     client = hello.client(protocol)     transport.open()      print "client - hellostring"     msg = client.hellostring("lalalalalla")     print "server - " + msg       transport.close()  except thrift.texception, ex:     print "%s" % (ex.message)  $ python py-client.py  client - hellostring server - lalalalalla

transportfactory := thrift.newtframedtransportfactory(thrift.newttransportfactory())

please change newtframedtransportfactory newtbufferedtransportfactory, transportfactory := thrift.newtbufferedtransportfactory(1024), thanks.

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
