在 python grpc 中,我得到一个异常“找不到服务器名称的匹配项”
In python grpc I got a exception “No match found for server name”
我用这个命令创建密钥:
openssl req -newkey rsa:2048 -nodes -keyout server.key -x509 -days 365 -out server.crt
我的服务器代码:
server_credentials = grpc.ssl_server_credentials(((_private_key, _certificate_chain,),))
server = grpc.server(futures.ThreadPoolExecutor(max_workers=MAX_THREADPOOL_EXECUTOR))
server.add_secure_port('[::]:{0}'.format(AGENT_PORT), server_credentials)
server.add_insecure_port('[::]:{0}'.format(AGENT_PORT))
print("AgentServicer start at port {}...".format(AGENT_PORT))
server.start()
try:
while True:
# we can do something in main thread......
time.sleep(_ONE_DAY_IN_SECONDS)
except KeyboardInterrupt:
server.stop(0)
我的客户代码:
credentials = grpc.ssl_channel_credentials(root_certificates=_certificate_chain)
channel = grpc.secure_channel('{}:{}'.format("localhost", 10010), credentials)
# channel = grpc.insecure_channel('{}:{}'.format("localhost", 10010))
stub = agent_pb2_grpc.AgentStub(channel)
response = stub.GetAgentVersion(agent_pb2.NoParams())
print("GreeterService client received: " + response.version)
我遇到异常:
No match found for server name
我做错了什么?
我怀疑您的服务器证书没有您尝试从客户端连接的 CN=localhost
。在这种情况下,您需要创建您的服务器证书以包含此类 Common Name
,或者您需要从您的客户端连接到证书中存在的名称。
