解决方案

  1. 100% 成功率 
    md := metadata.Pairs("authorization", "Bearer mytoken"); ctx := metadata.NewOutgoingContext(context.Background(), md)
  2. 90% 成功率 
    creds := credentials.NewClientTLSFromCert(nil, ""); conn, err := grpc.Dial(address, grpc.WithTransportCredentials(creds))
  3. 85% 成功率 
    interceptor := func(ctx context.Context, method string, req, reply interface{}, cc *grpc.ClientConn, invoker grpc.UnaryInvoker, opts ...grpc.CallOption) error { ctx = metadata.AppendToOutgoingContext(ctx, "authorization", "Bearer mytoken"); return invoker(ctx, method, req, reply, cc, opts...) }

无效尝试

常见但无效的做法:

  1. Sending an empty token or user/pass. 90% 失败

    Server still sees no valid credentials.

  2. Removing auth checks. 80% 失败

    Security risk.

  3. Not adding any metadata. 100% 失败

    Same error will occur.
