创建新的合并请求线程时引用的 GitLab line_code 是什么

Question

我正在尝试使用此端点使用 GitLab api 在文件的特定行上创建关于合并请求的讨论说明：https : //docs.gitlab.com/ee/api/discussions.html#create-new-合并请求线程

部分有效载荷要求 line_code

属性	类型	必需的	描述
位置[line_range][开始][line_code]	细绳	是的	起始行的行代码

当我发出 POST 时，我收到以下回复：

    "message": "400 (Bad request) \"Note {:line_code=>[\"can't be blank\", \"must be a valid line code\"], :position=>[\"is incomplete\"]}\" not given"

这是什么line_code？它是某种计算值吗？这里的文档相当模糊。

当我为 merge_request 上的所有当前注释发出 GET 时，我可以看到一些注释有这个line_code（见下文）。我试图弄清楚如何为新笔记创造价值。

Answer 1

行代码是hash of the file name + underscore + old line number + underscore + new line number

文档是错误的。line_code仅当您使用position.line_range仅在添加跨越多行差异的差异注释时才需要。您不需要处理line_code单行差异注释。所以它不是必需的参数。您可以只使用position.old_line或position.new_line。
