AstrBot HTTP API

从 v4.18.0 开始,AstrBot 提供基于 API Key 的 HTTP API,开发者可以通过标准 HTTP 请求访问核心能力。

快速开始

  1. 在 WebUI - 设置中创建 API Key。
  2. 在请求头中携带 API Key
Authorization: Bearer abk_xxx

也支持:

X-API-Key: abk_xxx
  1. 对于对话接口,username 为必填参数:
  • POST /api/v1/chat:请求体必须包含 username
  • GET /api/v1/chat/sessions:查询参数必须包含 username

Scope 权限说明

创建 API Key 时可配置 scopes。每个 scope 控制可访问的接口范围:

Scope 作用 可访问接口
chat 调用对话能力、查询对话会话 POST /api/v1/chatGET /api/v1/chat/sessions
config 获取可用配置文件列表 GET /api/v1/configs
file 上传附件文件,获取 attachment_id POST /api/v1/file
im 主动发 IM 消息、查询 bot/platform 列表 POST /api/v1/im/messageGET /api/v1/im/bots

如果 API Key 未包含目标接口所需 scope,请求会返回 403 Insufficient API key scope

常用接口

对话类

调用 AstrBot 内建的 Agent 进行对话交互。支持插件调用、工具调用等能力,与 IM 端对话能力一致。

  • POST /api/v1/chat:发送对话消息(SSE 流式返回,不传 session_id 会自动创建 UUID
  • GET /api/v1/chat/sessions:分页获取指定 username 的会话
  • GET /api/v1/configs:获取可用配置文件列表

文件上传

  • POST /api/v1/file:上传附件

IM 消息发送

  • POST /api/v1/im/message:按 UMO 主动发消息
  • GET /api/v1/im/bots:获取 bot/platform ID 列表

message 字段格式(重点)

POST /api/v1/chatPOST /api/v1/im/messagemessage 字段支持两种格式:

  1. 字符串:纯文本消息
  2. 数组:消息段(message chain

1. 纯文本格式

{
  "message": "Hello"
}

2. 消息段数组格式

{
  "message": [
    { "type": "plain", "text": "请看这个文件" },
    { "type": "file", "attachment_id": "9a2f8c72-e7af-4c0e-b352-111111111111" }
  ]
}

支持的 type

type 必填字段 可选字段 说明
plain text - 文本段
reply message_id selected_text 引用回复某条消息
image attachment_id - 图片附件段
record attachment_id - 音频附件段
file attachment_id - 通用文件段
video attachment_id - 视频附件段
  • reply 消息段目前仅适配 /api/v1/chat,不适用于 POST /api/v1/im/message

说明:

  • attachment_id 来自 POST /api/v1/file 上传结果。
  • reply 不能单独作为唯一内容,至少需要一个有实际内容的段(如 plain/image/file/...)。
  • reply 或空内容会返回错误。

Chat API 的 message 用法

POST /api/v1/chat 额外需要 username,可选 session_id(不传会自动创建 UUID)。

{
  "username": "alice",
  "session_id": "my_session_001",
  "message": [
    { "type": "plain", "text": "帮我总结这个 PDF" },
    { "type": "file", "attachment_id": "9a2f8c72-e7af-4c0e-b352-111111111111" }
  ],
  "enable_streaming": true
}

IM Message API 的 message 用法

POST /api/v1/im/message 需要 umo + message

{
  "umo": "webchat:FriendMessage:openapi_probe",
  "message": [
    { "type": "plain", "text": "这是主动消息" },
    { "type": "image", "attachment_id": "9a2f8c72-e7af-4c0e-b352-222222222222" }
  ]
}

示例

curl -N 'http://localhost:6185/api/v1/chat' \
  -H 'Authorization: Bearer abk_xxx' \
  -H 'Content-Type: application/json' \
  -d '{"message":"Hello","username":"alice"}'
