# Merge requests API[](#merge-requests-api "Permalink")

合并请求的每个 API 调用都必须经过验证.

**弃用** > `reference`响应属性有利于已弃用`references` . >推出了[GitLab 12.6](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/20354)**注意** > `references.relative`相对于正在请求合并请求的组/项目. 当从其项目中获取合并请求时> `relative`格式将与`short`格式相同，并且在跨组/项目进行请求时， `relative`格式应与`full`格式相同.

## List merge requests[](#list-merge-requests "Permalink")

在 GitLab 9.5 中[引入](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/13060) .

获取所有通过身份验证的用户有权访问的合并请求. 默认情况下，它仅返回当前用户创建的合并请求. 要获取所有合并请求，请使用参数`scope=all` .

`state`参数可用于仅获取具有给定状态（ `opened` ， `closed` ， `locked`或`merged` ）或全部（ `all` ）的合并请求. 应该注意的是，通过`locked`进行搜索时，由于它是短暂的过渡状态，因此几乎不会返回任何结果. 分页参数`page`和`per_page`可用于限制合并请求的列表.

```
GET /merge_requests
GET /merge_requests?state=opened
GET /merge_requests?state=all
GET /merge_requests?milestone=release
GET /merge_requests?labels=bug,reproduced
GET /merge_requests?author_id=5
GET /merge_requests?author_username=gitlab-bot
GET /merge_requests?my_reaction_emoji=star
GET /merge_requests?scope=assigned_to_me
GET /merge_requests?search=foo&in=title 
```

| `wip` | string | no | 过滤合并请求对他们的`wip`状态. `yes` ， *仅*返回 WIP 合并请求， `no` ，返回*非* WIP 合并请求 |   |
| `not` | Hash | no | 返回与提供的参数不匹配的合并请求. 接受： `labels` ， `milestone` ， `author_id` ， `author_username` ， `assignee_id` ， `assignee_username` ， `my_reaction_emoji` |   |

**注意：** [从 GitLab 13.0 开始](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/31890) ，列出合并请求可能不会主动更新`merge_status`字段（这也会影响`has_conflicts`字段），因为这可能是一项昂贵的操作. 如果您对此端点的这些字段的值感兴趣，请在查询`with_merge_status_recheck`参数设置为`true` .**注意：** [从 GitLab 12.8 开始，](https://gitlab.com/gitlab-org/gitlab/-/issues/29984)当对此端点发出请求时，将异步检查每个合并请求的可合并性（ `merge_status` ）. 轮询此 API 端点以获取更新状态. 这会影响`has_conflicts`属性，因为它取决于`merge_status` . 除非`merge_status`为`cannot_be_merged`否则它将返回`false` .

```

## List project merge requests[](#list-project-merge-requests "Permalink")

获取此项目的所有合并请求. `state`参数可用于仅获取具有给定状态（ `opened` ， `closed` ， `locked`或`merged` ）或全部（ `all` ）的合并请求. 分页参数`page`和`per_page`可用于限制合并请求的列表.

`project_id`代表 MR 所在项目的 ID. `project_id`将始终等于`target_project_id` .

如果来自同一项目的合并请求，则`source_project_id` ， `target_project_id`和`project_id`将相同. 对于来自派生的合并请求， `target_project_id`和`project_id`将相同，并且`source_project_id`将是派生项目的 ID.

## Get single MR[](#get-single-mr "Permalink")

显示有关单个合并请求的信息.

**注意** ：响应中的`changes_count`值是一个字符串，而不是整数. 这是因为当 MR 有太多要显示和存储的更改时，其上限为 1,000\. 在这种情况下，API 将为更改计数返回字符串`"1000+"` .

```
GET /projects/:id/merge_requests/:merge_request_iid 
```

Parameters:

*   `id` （必填）-经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding)
*   `merge_request_iid` （必需）-合并请求的内部 ID
*   `render_html` (optional) - If `true` response includes rendered HTML for title and description
*   `include_diverged_commits_count` （可选）-如果为`true`包括目标分支后面的提交
*   `include_rebase_in_progress` （可选）-如果为`true`包括是否正在进行 rebase 操作

**注意：** [从 GitLab 12.8 开始，](https://gitlab.com/gitlab-org/gitlab/-/issues/29984)当对此端点发出请求时，将异步检查合并请求的可合并性（ `merge_status` ）. 轮询此 API 端点以获取更新状态. 这会影响`has_conflicts`属性，因为它取决于`merge_status` . 除非`merge_status`为`cannot_be_merged`否则它将返回`false` .

```

Parameters:

*   `id` （必填）-经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding)
*   `merge_request_iid` （必需）-合并请求的内部 ID

## Create MR Pipeline[](#create-mr-pipeline "Permalink")

在 GitLab 12.3 中[引入](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/31722) .

[为合并请求](../ci/merge_request_pipelines/index.html)创建一个新[管道](../ci/merge_request_pipelines/index.html) . 通过这个端点创建的管道将无法运行常规的分支/标签的管道，它需要`.gitlab-ci.yml`与配置`only: [merge_requests]`创造就业机会.

新管道可以是：

*   分离的合并请求管道.
*   A [pipeline for merged results](../ci/merge_request_pipelines/pipelines_for_merged_results/index.html) if the [project setting is enabled](../ci/merge_request_pipelines/pipelines_for_merged_results/index.html#enable-pipelines-for-merged-results).

```
POST /projects/:id/merge_requests/:merge_request_iid/pipelines 
```

Parameters:

*   `id` （必填）-项目的 ID 或[URL 编码的路径](README.html#namespaced-path-encoding)
*   `merge_request_iid` （必需）-合并请求的内部 ID

```

```

## Create MR[](#create-mr "Permalink")

创建一个新的合并请求.

```
POST /projects/:id/merge_requests 
```

| Attribute | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | integer/string | yes | 经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding) |
| `source_branch` | string | yes | 源分支 |
| `target_branch` | string | yes | 目标分支 |
| `title` | string | yes | 先生的头衔 |
| `assignee_id` | integer | no | 受让人用户 ID |
| `assignee_ids` | 整数数组 | no | 要将 MR 分配给的用户的 ID. 设置为`0`或提供一个空值以取消分配所有受让人. |
| `description` | string | no | MR 的描述. 限制为 1,048,576 个字符. |
| `target_project_id` | integer | no | 目标项目（数字 ID） |
| `labels` | string | no | MR 的标签以逗号分隔的列表 |
| `milestone_id` | integer | no | 里程碑的全局 ID |
| `remove_source_branch` | boolean | no | 指示合并请求是否应在合并时删除源分支的标志 |
| `allow_collaboration` | boolean | no | 允许来自可以合并到目标分支的成员的提交 |
| `allow_maintainer_to_push` | boolean | no | Deprecated, see allow_collaboration |
| `squash` | boolean | no | 合并时将 Squash 提交到单个提交中 |

如果`approvals_before_merge` 未提供，它将从目标项目继承值. 如果提供了它，则必须满足以下条件才能使其生效：

1.  目标项目的`approvals_before_merge`必须大于零. 零值将禁用该项目的批准.

## Merge to default merge ref path[](#merge-to-default-merge-ref-path "Permalink")

如果可能，将合并请求源和目标分支之间的更改合并到目标项目存储库的`refs/merge-requests/:iid/merge` ref 中. 如果执行常规合并操作，此引用将具有目标分支将具有的状态.

这不是常规的合并操作，因为它不会以任何方式更改合并请求目标分支的状态.

向此 API 提交请求时，此 ref（ `refs/merge-requests/:iid/merge` ）不一定会被覆盖，尽管它可以确保 ref 具有最新的状态.

如果合并请求有冲突，为空或已经合并，您将收到一条`400`和一个描述性错误消息.

如果为`200`它将在响应正文中返回`refs/merge-requests/:iid/merge`的 HEAD 提交.

```
GET /projects/:id/merge_requests/:merge_request_iid/merge_ref 
```

Parameters:

*   `id` （必填）-经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding)
*   `merge_request_iid` （必需） `merge_request_iid`内部 ID

```
{  "commit_id":  "854a3a7a17acbcc0bbbea170986df1eb60435f34"  } 
```

## Cancel Merge When Pipeline Succeeds[](#cancel-merge-when-pipeline-succeeds "Permalink")

如果您没有接受此合并请求的权限-您会收到`401`

如果合并请求已被合并或关闭-您将收到`405`和错误消息"不允许使用方法"

如果在管道成功时未将合并请求设置为要合并，则还会收到`406`错误.

```
POST /projects/:id/merge_requests/:merge_request_iid/cancel_merge_when_pipeline_succeeds 
```

Parameters:

*   `id` （必填）-经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding)
*   `merge_request_iid` （必需） `merge_request_iid`内部 ID

## Rebase a merge request[](#rebase-a-merge-request "Permalink")

自动将合并请求的`source_branch`与其`target_branch` .

如果您无权推送到合并请求的源分支-您将收到`403 Forbidden`响应.

```
PUT /projects/:id/merge_requests/:merge_request_iid/rebase 
```

| Attribute | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | integer/string | yes | 经过身份验证的用户拥有[的项目](README.html#namespaced-path-encoding)的 ID 或[URL 编码路径](README.html#namespaced-path-encoding) |
| `merge_request_iid` | integer | yes | 合并请求的内部 ID |
| `skip_ci` | boolean | no | 设置为`true`以跳过创建 CI 管道 |

```
curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/76/merge_requests/1/rebase" 
```

这是一个异步请求. 如果请求成功入队，API 将返回`202 Accepted`响应，响应包含：

```
{  "rebase_in_progress":  true  } 
```

您可以使用`include_rebase_in_progress`参数轮询" [获取单个 MR"](#get-single-mr)端点，以检查异步请求的状态.

如果正在进行 rebase 操作，则响应将包括以下内容：

```
{  "rebase_in_progress":  true,  "merge_error":  null  } 
```

一旦成功完成了变基操作，响应将包括以下内容：

```
{  "rebase_in_progress":  false,  "merge_error":  null  } 
```

如果 rebase 操作失败，响应将包括以下内容：

```
{  "rebase_in_progress":  false,  "merge_error":  "Rebase failed. Please rebase locally"  } 
```
