python protobuf序列化repeated运用

下面是proto描述文件的定义

message Person {
  required string name = 1;
  required int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }

  repeated PhoneNumber phone = 4;
}

message AddressBook {
  repeated Person person = 1;
}

在python中利用google.protobuf序列化数据进行通讯的时候，一定会遇到repeated的数据如何去创建

在这里我给大家分享一下：

import addressbook_pb2
person = addressbook_pb2.Person()
person.id = 1234
person.name = "John Doe"
person.email = "[email protected]"
phone = person.phone.add()
phone.number = "555-4321"
phone.type = addressbook_pb2.Person.HOME
person.no_such_field = 1
person.id = "1234" 

请注意加红的一行代码，这就是重点，如果想再添加一个的话phone2 = person.phone.add()即可，然后给phone2赋值。
