我有一个结构
type Products struct {
Name string
Version string
Description string
}
持有多行字符串常量作为 Description 字段的值，常量如下
const DEFAULT_DESCRIPTION = `Please add the description here without removing the literal block (|)
Sample description will be as follows,
Fixes for the following in rabbitmq transport
(i) Channel not closing issue in rabbitmq publisher
(ii) Performance improvements to the transport by introducing a channel pool (configurable) and parameterising queue and exchange creation.
(iii) Allow configuring connection factory by name in target url`
然后我使用包 gopkg.in/yaml.v2 来封送上面的结构（包含上面的常量作为其字段的值），如下所示
data, err = yaml.Marshal(updateDescriptorV3)
并使用 os.file.Write() 将生成的 yaml 内容写入文件但是在上面生成的 yaml 文件中，在literal_block符号后出现了另一个 - （ | ）我做错了什么？
description: |-

需要做些什么来使上面的常量作为 yaml 中的literal_block如下？
description: |

它运作正常 . 您的多行字符串不以换行符结尾，因此YAML必须在解析时删除换行符 . 这正是
|-所做的 .如果您真的想要
|，只需在输入字符串的末尾添加换行符，但要注意功能差异 .有关在YAML中包含多行字符串的各种方法的完整说明，请参阅this answer .
