Apache Thrift是一个跨语言的远程服务框架,用于在不同的编程语言之间进行通信。在Apache Thrift中,参数列表中的FieldReq用于指定字段的必需性。
以下是一个示例代码,演示如何在Apache Thrift中使用FieldReq参数:
namespace java com.example.thrift
namespace py com.example.thrift
struct Person {
1: required i32 id,
2: optional string name,
3: required string email
}
service MyService {
void savePerson(1: required Person person)
}
thrift -r --gen java YourThriftFile.thrift
thrift -r --gen py YourThriftFile.thrift
import com.example.thrift.Person;
import com.example.thrift.MyService;
public class MyServiceImpl implements MyService.Iface {
@Override
public void savePerson(Person person) {
// 处理保存Person的逻辑
System.out.println("Saving person: " + person);
}
}
from com.example.thrift import MyService
from com.example.thrift.ttypes import Person
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
# 创建Thrift客户端
transport = TSocket.TSocket('localhost', 9090)
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = MyService.Client(protocol)
# 打开连接
transport.open()
# 创建Person对象
person = Person()
person.id = 1
person.name = "John Doe"
person.email = "john@example.com"
# 调用远程服务
client.savePerson(person)
# 关闭连接
transport.close()
请注意,上述示例仅用于演示如何在Apache Thrift中使用FieldReq参数。您可以根据您的需求进行更改和扩展。
