wan2.7-r2v(參考圖生影片)的建立介面:給參考圖/參考影片,模型保留其中的主體(人物/動物/物體)和場景特徵,生成單角色表演或多角色互動影片。需要更多參考圖(≤9 張)可考慮 HappyHorse r2v。完整非同步流程見 Wan 概覽。- 參考素材引用約定:prompt 中用「圖1 / 圖2」指代
reference_image、「影片1 / 影片2」指代reference_video,順序與media陣列一致(圖和影片分別計數)。僅一張圖/一個影片時可簡寫為「參考圖片」「參考影片」。 - 數量限制:
reference_image+reference_video合計 ≤5;first_frame最多 1 張。 - 建立請求走
/wan/api/v1/...並帶X-DashScope-Async: enable,不要用/v1/videos。

parameters.watermark | bool | false | 「AI 生成」水印 |
media[] 取值
type | 張數/限制 | 說明 |
|---|---|---|
reference_image | 與 video 合計 ≤5 | 參考圖,提供主體(人物/動物/物體)或場景;可附 reference_voice 指定音色 |
reference_video | 與 image 合計 ≤5 | 參考影片,提供主體與音色參考;不建議傳空鏡影片 |
first_frame | ≤1 | 可選首幀,聯合控制起始畫面 |
reference_voice | 附屬欄位 | 附在某條 reference_image/reference_video 上,指定該主體音色(wav/mp3,1–10s) |

查詢狀態與下載影片
拿到task_id 後,按以下三步查詢狀態並下載 mp4:
- 輪詢
GET /v1/tasks/{task_id}(帶Authorization,查詢不需要X-DashScope-Async頭),每 10 秒一次(不要 < 3 秒),直到status變為completed。參考生影片耗時通常 1–5 分鐘,建議客戶端超時設 20 分鐘兜底。 - 狀態取值:
submitted(排隊)/in_progress(生成中,progress常停在 30% 屬正常)/completed(成功)/failed(失敗,看error)。 - 下載:從響應的
result_url直接 GET,不要帶Authorization頭(OSS 簽名直鏈,帶了反而 403);result_url預設 24 小時過期,務必儘快轉存。
curl "https://api.apiyi.com/v1/tasks/acda59b4-3b10-4789-a5e5-edadae48adcb" \

"task_id": "acda59b4-3b10-4789-a5e5-edadae48adcb"

# result_url 是 OSS 簽名直鏈,下載時不要帶 Authorization 頭(帶了反而 403)
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."

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" # 不帶 Authorization
