概述

对于异步任务（Midjourney 绘图、视频生成、音乐生成等），Crazyrouter 支持通过 Webhook 回调通知任务状态变更。

​
回调 URL 配置

在提交任务时，通过 notifyHook 参数指定回调地址： 
{
  "prompt": "a beautiful sunset",
  "notifyHook": "https://your-server.com/api/callback"
}

​
回调请求格式

Crazyrouter 会向你的回调 URL 发送 POST 请求： 
POST https://your-server.com/api/callback
Content-Type: application/json

​
Midjourney 回调

{
  "id": "task_abc123",
  "action": "IMAGINE",
  "status": "SUCCESS",
  "prompt": "a beautiful sunset",
  "imageUrl": "https://cdn.example.com/image.png",
  "progress": "100%",
  "failReason": "",
  "submitTime": 1706000000000,
  "startTime": 1706000010000,
  "finishTime": 1706000060000
}

​
视频生成回调（Kling/Luma/Runway）

{
  "id": "task_xyz789",
  "status": "succeed",
  "type": "video",
  "output": {
    "video_url": "https://cdn.example.com/video.mp4",
    "cover_url": "https://cdn.example.com/cover.jpg",
    "duration": 5.0
  },
  "created_at": 1706000000,
  "updated_at": 1706000120
}

​
Suno 音乐回调

{
  "id": "task_music456",
  "status": "complete",
  "output": {
    "audio_url": "https://cdn.example.com/song.mp3",
    "title": "My Song",
    "duration": 180
  }
}

​
回调状态流转

提交 → NOT_START → IN_PROGRESS → SUCCESS / FAILURE
每次状态变更都会触发一次回调。

​
回调服务端示例

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route("/api/callback", methods=["POST"])
def callback():
    data = request.json
    task_id = data["id"]
    status = data["status"]

    print(f"任务 {task_id} 状态更新: {status}")

    if status == "SUCCESS":
        image_url = data.get("imageUrl")
        print(f"图片地址: {image_url}")

    return jsonify({"success": True})

app.run(port=8080)
回调 URL 必须是公网可访问的地址。请确保你的服务器能接收 POST 请求，并在 5 秒内返回 200 状态码。
如果回调失败，系统会重试最多 3 次，间隔分别为 10 秒、30 秒、60 秒。
