Hello,
I use an objective c client and the server is go, when I try to stream from
the server to the client I encounter this problem, do you have any idea
why? Thank you very much
Error: SSL routines:OPENSSL_internal:WRONG_VERSION_NUMBER
Proto:
service Event {
rpc eventSubscription ( stream eventRequest) returns ( stream
eventResponse) {}
rpc listFeatures(eventRequest) returns (stream eventResponse) {}
}
message eventRequest {
string id = 1;
}
message eventResponse {
string id = 1;
string key = 2;
string value = 3;
}
ObjC code:
#import <Foundation/Foundation.h>
#import <GRPCClient/GRPCCall+Tests.h>
#import "GrpcService.h"
#import <GrpcService/Event.pbrpc.h>
static NSString * const hostAddress = @"localhost:50052";
RCT_EXPORT_METHOD(stream:(NSString *)name)
{
[GRPCCall useInsecureConnectionsForHost:hostAddress];
CPHWEvent *client = [[CPHWEvent alloc] initWithHost:hostAddress];
CPHWeventRequest *request = [CPHWeventRequest message];
GRPCUnaryResponseHandler *handler =
[[GRPCUnaryResponseHandler alloc] initWithResponseHandler:
^(CPHWeventResponse *response, NSError *error) {
if (response) {
NSLog(@"%@", response);
} else {
}
} responseDispatchQueue:nil];
GRPCUnaryProtoCall *call = [client listFeaturesWithMessage:request
responseHandler:handler callOptions:nil];
[call start];
}
Go code:
func (s *Server) EventSubscription(stream
pbEvent.Event_EventSubscriptionServer) error {
log.Println("Started stream")
var length int
length = len(global.TestStrings)
for {
TestStrings := global.TestStrings
if len(TestStrings) > length {
response := &pbEvent.EventResponse{
Id: TestStrings[length].Id,
Value: TestStrings[length].Value,
Key: TestStrings[length].Key,
}
if err := stream.Send(response); err != nil {
log.Println(err)
} else {
log.Println("send...")
//global.TestStrings = append(global.TestStrings[:0],
global.TestStrings[1:]...)
length++
}
}
}
