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 = ""
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
