Create a review comment for a pull request

适用于 GitHub Apps

Creates a review comment in the pull request diff. To add a regular comment to a pull request timeline, see "Create an issue comment." We recommend creating a review comment using line, side, and optionally start_line and start_side if your comment applies to more than one line in the pull request diff.

The position parameter is deprecated. If you use position, the line, side, start_line, and start_side parameters are not required.

Note: The position value equals the number of lines down from the first "@@" hunk header in the file you want to add a comment. The line just below the "@@" line is position 1, the next line is position 2, and so on. The position in the diff continues to increase through lines of whitespace and additional hunks until the beginning of a new file.

This endpoint triggers notifications. Creating content too quickly using this endpoint may result in secondary rate limiting. See "Secondary rate limits" and "Dealing with secondary rate limits" for details.

正文参数

`path` string 必须 The relative path to the file that necessitates a comment.
`position` integer This parameter is deprecated. Use `line` instead. The position in the diff where you want to add a review comment. Note this value is not the same as the line number in the file. For help finding the position value, read the note above.
`side` string In a split diff view, the side of the diff that the pull request's changes appear on. Can be `LEFT` or `RIGHT`. Use `LEFT` for deletions that appear in red. Use `RIGHT` for additions that appear in green or unchanged lines that appear in white and are shown for context. For a multi-line comment, side represents whether the last line of the comment range is a deletion or addition. For more information, see "Diff view options" in the GitHub Help documentation. 可以是以下选项之一: `LEFT`, `RIGHT`

`start_side` string Required when using multi-line comments unless using `in_reply_to`. The `start_side` is the starting side of the diff that the comment applies to. Can be `LEFT` or `RIGHT`. To learn more about multi-line comments, see "Commenting on a pull request" in the GitHub Help documentation. See `side` in this table for additional context. 可以是以下选项之一: `LEFT`, `RIGHT`, `side`
`in_reply_to` integer The ID of the review comment to reply to. To find the ID of a review comment with "List review comments on a pull request". When specified, all parameters other than `body` in the request body are ignored.

Create a reply for a review comment

Creates a reply to a review comment for a pull request. For the comment_id, provide the ID of the review comment you are replying to. This must be the ID of a top-level review comment, not a reply to that comment. Replies to replies are not supported.

This endpoint triggers notifications. Creating content too quickly using this endpoint may result in secondary rate limiting. See "Secondary rate limits" and "Dealing with secondary rate limits" for details.
