   > 1、single_repeated_to_array字段的注释中，default是false。
   > 2、但是实际使用时发现，默认是开启的。例如
   > "my_field": ["value1"], my_field是一个repeated字段，没有设置single_repeated_to_array的情况下，仍然解析为array
   > ```
   
   参考这个示例：
   https://github.com/apache/incubator-brpc/blob/master/docs/cn/json2pb.md#repeated-field
   
   效果是当开启`single_repeated_to_array` 时，序列化为:
   ```json
   ["value1"]
   ```
   而不是
   ```json
   {
      "my_field": ["value1"]
   }
   ```
   
   假设使用的 proto 是:
   ```proto
   message foo {
       repeated string my_field = 1;
   }
   ```
