英文:
GRPC ConnectivityState is not working true?
问题
ManagedChannel managedChannel = ManagedChannelBuilder
.forAddress("localhost", 9090)
.usePlaintext().build();
System.out.println("State: " + managedChannel.getState(false)) // State: IDLE
Grpc.Stub stub = Grpc.newStub(managedChannel);
System.out.println("State: " + managedChannel.getState(false)) // State: IDLE
stub.callMethod();
System.out.println("State: " + managedChannel.getState(false)) // State: IDLE
以上代码是 GRPC 客户端代码。它与 GRPC 服务器建立连接。但每次通道状态都是 IDLE？什么时候是 CONNECTING 和 READY 状态？有什么问题吗？
英文:
ManagedChannel managedChannel = ManagedChannelBuilder
.forAddress("localhost", 9090)
.usePlaintext().build();
System.out.println("State: " + managedChannel .getState(false)) // State: IDLE
Grpc.Stub stub = Grpc.newStub(managedChannel);
System.out.println("State: " + managedChannel .getState(false)) // State: IDLE
stub.callMethod();
System.out.println("State: " + managedChannel .getState(false)) // State: IDLE
Above code is GRPC client. It get connection with grpc server. But every time the channel state is IDLE? When is CONNECTING and READY state? Whats wrong?

需要等待另一种状态。
当服务器未启动时，以下代码会打印connection state: TRANSIENT_FAILURE，当服务器健康时会打印connection state: READY。
gRPC版本：1.24.0
ManagedChannel managedChannel = ManagedChannelBuilder
.forAddress("localhost", 9090)
.usePlaintext().build();
ConnectivityState state = channel.getState(true);
while (state == ConnectivityState.IDLE || state == ConnectivityState.CONNECTING) {
state = channel.getState(true);
}
System.out.println("connection state: " + state.toString());
英文:
It is required to wait for another state.
The following code prints connection state: TRANSIENT_FAILURE when server is not started and connection state: READY when it is healthy.
gRPC version: 1.24.0
ManagedChannel managedChannel = ManagedChannelBuilder
.forAddress("localhost", 9090)
.usePlaintext().build();
ConnectivityState state = channel.getState(true);
while (state == ConnectivityState.IDLE || state == ConnectivityState.CONNECTING) {
state = channel.getState(true);
}
System.out.println("connection state: " + state.toString());
