gitlab - 创建新的合并请求线程时引用的 GitLab line_code 是什么

Question

我正在尝试使用以下端点使用 GitLab api 在文件的特定行上创建关于合并请求的讨论笔记:https://docs.gitlab.com/ee/api/discussions.html#create-new-merge-request-thread
部分有效载荷要求提供 line_code

属性
类型
必需的
描述


位置[line_range][开始][line_code]
字符串
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。
当我针对 merge_request 上的所有当前注释发出 GET 时，我可以看到一些注释包含此 line_code (见下文)。我试图弄清楚如何为新笔记创造值(value)。

Answer 1

线路代码是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 时才需要这仅用于添加跨越多行差异的差异注释。你不需要处理line_code用于单行差异注释。所以它不是必需的参数。您可以使用 position.old_line或 position.new_line .
