the provider use java language,and the protocol use dubbo or hessian, the result is same. and the provider can print the log ================hello python dubbo client name:A000000
the provider config is below:
spring.application.name = dubbo-provider
server.port = 9090
#指定当前服务/应用的名字(同样的服务名字相同,不要和别的服务同名)
dubbo.application.name = dubbo-provider
demo.service.version = 1.0.0
#dubbo.protocol.name = jsonrpc
#dubbo.protocol.name = hessian
#dubbo.protocol.port = 8888
#指定注册中心的位置
dubbo.registry.address = zookeeper://localhost:2181
#统一设置服务提供方的规则
dubbo.provider.timeout = 1000
and the interface as below:
@Service(version = "${demo.service.version}")
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
System.out.println("================hello python dubbo client name:"+name);
return "Hello, " + name + " (from Spring Boot)";
}
}
the consumer as below:
# -*- coding: utf-8 -*-
from dubbo.client import DubboClient, ZkRegister, logging
# LOG_FILENAME = 'example.log'
logging.basicConfig(level=logging.DEBUG)
# logging.basicConfig(filename=LOG_FILENAME, level=logging.DEBUG)
logging.debug('logger---------------:')
# 支持从Zk中获取服务的provider,支持根据provider的权重选择主机
zk = ZkRegister('127.0.0.1:2181')
dubbo_cli = DubboClient('com.xiaoze.api.service.DemoService', zk_register=zk)
# 支持不使用Zk,直接连接指定的远程主机
# dubbo_cli = DubboClient('com.xiaoze.api.service.DemoService', host='127.0.0.1:8888')
name = 'A000000'
result = dubbo_cli.call('sayHello', name, timeout=60000)
logging.debug("++++++++++++++++")
logging.info("==========================="+result)
It seems that there is no response message sent by the server, there is currently no way to determine the reason, it is recommended to use Wireshark to capture the network packet and analysis it.
