python proto repeated对象赋值报错 ‘Assignment not allowed to repeated field “***“ in protocol messag‘

proro文件

syntax = "proto3";

message TestRequest {
    # 修饰符  类型  字段名 序号
    repeated int32 ids = 1;  
}    

ids的类型是int32，然后被repeated修饰，即这个字段是可重复赋值的。

错误示例：

request = TestRequest()
request.ids = [0]

报错

AttributeError: Assignment not allowed to repeated field “ids” in protocol message object.

正确方法：

request = TestRequest()
request.ids.append(1)

将被repeated修饰的字段看作是一个空列表,往里面添加值即可
