Parsing a protocol message from Go by Java -

i write server(go)-client(java) programe, , use protobuf communication. define proto file , share between server , client. in server side:

• compile shared proto file go protoc
• serialize object proto.marshal
• send client make request service

in client side:

• compile shared proto file java protoc
• get bytes transferred via http
• deserialize bytes object.

here following error:

"com.google.protobuf.invalidprotocolbufferexception: while parsing protocol message, input ended unexpectedly in middle of field. mean either input has been truncated or embedded message misreported own length."

i confirmed http work fine , value of bytes received in client side same bytes send server. have same problem on this?

here proto file

syntax = "proto3"; package tutorial;  message person {     string name = 1;     int32 id = 2;      string email = 3;      enum phonetype {         mobile = 0;         home = 1;         work = 2;     }      message phonenumber {         string number = 1;         phonetype type = 2;     }      repeated phonenumber phones = 4; }  message addressbook {     repeated person people = 1; } 

in go server side :

func todoindex(w http.responsewriter, r *http.request) {      w.header().set("content-type", "application/x-protobuf")     w.writeheader(http.statusok)     p := &person{         id:    1234,         name:  "john doe",         email: "jdoe@example.com",         phones: []*person_phonenumber{             {number: "555-4321", type: person_home},         },     }     out, err := proto.marshal(p)     if err != nil {         panic(err)     }     w.write(out) } 

in java client side:

public class mainjavaandgo { public static void main(string[] args){     try {         long start = (new date()).gettime();         system.out.println("begin get");         connect();          system.out.println("end get");         long time = (new date()).gettime() - start;     }catch(exception e){         e.printstacktrace();     } }  public static void connect(){     defaultbhttpclientconnection connection = new defaultbhttpclientconnection(8 * 1024);     httphost server = hostforstring("localhost:8080");     try {          socket socket = new socket(server.gethostname(), server.getport());         connection.bind(socket);          httpcorecontext writecontext = httpcorecontext.create();         writecontext.settargethost(server);          basichttpentityenclosingrequest httprequest = new basichttpentityenclosingrequest("get",                 "/todos");          httpprocessor httpproc = makehttpprocessor();         httprequestexecutor httpexecutor = new httprequestexecutor();         httpexecutor.preprocess(httprequest, httpproc, writecontext);         httpresponse response = httpexecutor.execute(httprequest, connection, writecontext);         httpexecutor.postprocess(response, httpproc, writecontext);         inputstream inputstream = response.getentity().getcontent();         byte[] data = ioutils.tobytearray(inputstream);         addressbook.addressbook addressbook = addressbook.addressbook.parsefrom(data);         int foo = 0;         foo++;       }catch(exception e){         e.printstacktrace();         try {             connection.shutdown();         }catch (exception ioe){             ioe.printstacktrace();         }     } } public static  httphost hostforstring(string hoststr) {     string[] host = hoststr.split(":", 2);     httphost httphost = new httphost(host[0], integer.parseint(host[1]));      return httphost; }  public static httpprocessor makehttpprocessor() {     return httpprocessorbuilder.create().add(new requestcontent()).add(new requesttargethost())             .add(new requestconncontrol()).add(new requestuseragent("test protobuf/1.1"))             .add(new requestexpectcontinue(true)).build(); } } 

i got invalidprotocolbufferexception

thank found answer comment. serialize , deserialize structure different. edited addressbook.person person = addressbook.person.parsefrom(data); , work.
