Suno API 的 Go 调用示例

准备

Go 1.20+，Key 放环境变量。用 context.WithTimeout 给提交和轮询设置分钟级超时；生成是异步的，提交成功不等于完成。

提交与解析

type createResp struct {
    Data struct {
        Clips []struct {
            SongID string `json:"song_id"`
        } `json:"clips"`
    } `json:"data"`
}

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Minute)
defer cancel()
body := strings.NewReader(`{"description":"city pop, 90s, female vocal","model":"suno-v6"}`)
req, _ := http.NewRequestWithContext(ctx, "POST", base+"/api/music/create", body)
req.Header.Set("Authorization", "Bearer "+os.Getenv("SUNO_API_KEY"))
req.Header.Set("Content-Type", "application/json")

resp, err := http.DefaultClient.Do(req)
if err != nil { return err }
defer resp.Body.Close()
var out createResp
json.NewDecoder(resp.Body).Decode(&out)
songID := out.Data.Clips[0].SongID

轮询与并发

每 3–5 秒查一次，状态到 complete/completed 再取地址；failed/error 读原因并停止。批量时用 worker pool + 有缓冲 channel，别为每首歌无限起 goroutine；429 时退避并降低并发。
