}右侧 Playground 可直接调试:在 Authorization 填
Bearer sk-your-api-key,填好 model / input / parameters 后发起请求。提交成功会返回 task_id,后续轮询与下载见下方说明。- 创建请求必须走
/wan/api/v1/services/aigc/video-generation/video-synthesis并带请求头X-DashScope-Async: enable,不要用/v1/videos。 duration必须是 整数(5不是"5");resolution写 大写720P。

参数说明速查
| 参数 | 类型 | 必填 | 默认 | 说明 |
|---|---|---|---|---|
model | string | ✓ | — | 固定 wan2.7-t2v |
input.prompt | string | ✓ | — | 文本提示词,建议描述场景、镜头运动、光线、风格 |
input.negative_prompt | string | — | 反向提示词,≤500 字符 | |
parameters.resolution | string | 720P | 720P / 1080P(大写) | |
parameters.ratio | string | 16:9 | 16:9 / 9:16 / 1:1 / 4:3 / 3:4 | |
parameters.duration | int | 5 | 2–15 秒整数 | |
parameters.prompt_extend | bool | true | 智能改写,推荐开启 | |
parameters.watermark | bool | false | 右下角「AI 生成」水印 | |
parameters.seed | int | 随机 | 0–2147483647,固定可复现 |
响应格式
创建成功返回task_id(不是视频本身):
{
"output": { "task_id": "c2e7570c-0af2-4eba-919f-3af3d1164a38", "task_status": "PENDING" },
"request_id": "a23b81b0-0c05-9972-a6c9-ee757400afdb"
}
查询状态与下载视频
拿到task_id 后,按以下三步查询状态并下载 mp4:
- 轮询
GET /v1/tasks/{task_id}(带Authorization,查询不需要X-DashScope-Async头),每 5–10 秒一次(不要 < 3 秒),直到status变为completed。 - 状态取值:
submitted(排队)/in_progress(生成中,progress常停在 30% 属正常)/completed(成功)/failed(失败,看error)。 - 下载:从响应的
result_url直接 GET,不要带Authorization头(OSS 签名直链,带了反而 403);result_url默认 24 小时过期,务必尽快转存。
curl "https://api.apiyi.com/v1/tasks/c2e7570c-0af2-4eba-919f-3af3d1164a38" \
-H "Authorization: Bearer sk-your-api-key"
{
"status": "completed",
"progress": 100,
"result_url": "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=...",
"task_id": "c2e7570c-0af2-4eba-919f-3af3d1164a38"
}
# result_url 是 OSS 签名直链,下载时不要带 Authorization 头(带了反而 403)
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."
TASK_ID="c2e7570c-0af2-4eba-919f-3af3d1164a38"
URL=$(curl -s "https://api.apiyi.com/v1/tasks/$TASK_ID" \
-H "Authorization: Bearer sk-your-api-key" | jq -r '.result_url')
curl -L -o out.mp4 "$URL" # 不带 Authorization
上面是「已有 task_id」的快捷查询/下载。完整轮询循环(含超时兜底)与 Python 客户端见 Wan 概览 · 异步调用流程。
