在web应用后端接入内容审核——以腾讯云音频审核为例（Go语言示例）

腾讯云对象存储数据万象（Cloud Infinite，CI）为用户提供图片、视频、语音、文本等文件的内容安全智能审核服务，帮助用户有效识别涉黄、违法违规和广告审核，规避运营风险。本文以音频审核为例给出go语言示例代码与相应结果。

一、预备条件

获取API密钥，不可泄漏
https://console.cloud.tencent.com/cam/capi
将SecretId与SecretKey写到环境变量

二、实现代码

package mainimport ("context""fmt""net/http""net/url""os""path/filepath""github.com/gin-gonic/gin"cos "github.com/tencentyun/cos-go-sdk-v5"
)var cosClient *cos.Clientfunc initCOSClient() error {secretID := os.Getenv("SecretId")secretKey := os.Getenv("SecretKey")if secretID == "" || secretKey == "" {return fmt.Errorf("SecretId and SecretKey environment variables are required")}bu, _ := url.Parse("https://radio-1259203851.cos.ap-shanghai.myqcloud.com")cu, _ := url.Parse("https://radio-1259203851.ci.ap-shanghai.myqcloud.com")b := &cos.BaseURL{BucketURL: bu, CIURL: cu}cosClient = cos.NewClient(b, &http.Client{Transport: &cos.AuthorizationTransport{SecretID:  secretID,SecretKey: secretKey,},})return nil
}func main() {if err := initCOSClient(); err != nil {fmt.Printf("Failed to initialize COS client: %v\n", err)fmt.Println("Please set the following environment variables:")fmt.Println("export SecretId=YOUR_SECRET_ID")fmt.Println("export SecretKey=YOUR_SECRET_KEY")os.Exit(1)}r := gin.Default()// 文件上传接口r.POST("/upload", func(c *gin.Context) {file, err := c.FormFile("file")if err != nil {c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})return}// 保存上传的文件到临时目录tempDir := "temp"if err := os.MkdirAll(tempDir, 0755); err != nil {c.JSON(http.StatusInternalServerError, gin.H{"error": err.Error()})return}tempFilePath := filepath.Join(tempDir, file.Filename)if err := c.SaveUploadedFile(file, tempFilePath); err != nil {c.JSON(http.StatusInternalServerError, gin.H{"error": err.Error()})return}// 上传文件到COScosKey := "audios/" + file.Filename_, err = cosClient.Object.PutFromFile(context.Background(), cosKey, tempFilePath, nil)if err != nil {c.JSON(http.StatusInternalServerError, gin.H{"error":   err.Error(),"message": "Failed to upload file to COS",})return}// 提交审核任务opt := &cos.PutAudioAuditingJobOptions{InputObject: cosKey,Conf:        &cos.AudioAuditingJobConf{},}res, _, err := cosClient.CI.PutAudioAuditingJob(context.Background(), opt)if err != nil {c.JSON(http.StatusInternalServerError, gin.H{"error":   err.Error(),"message": "Failed to submit audio auditing job",})return}// 清理临时文件os.Remove(tempFilePath)// 返回任务IDc.JSON(http.StatusOK, gin.H{"job_id":  res.JobsDetail.JobId,"cos_key": cosKey,})})// 查询审核结果接口r.GET("/result/:job_id", func(c *gin.Context) {jobID := c.Param("job_id")// 查询审核结果res, _, err := cosClient.CI.GetAudioAuditingJob(context.Background(), jobID)if err != nil {c.JSON(http.StatusInternalServerError, gin.H{"error":   err.Error(),"message": "Failed to get audio auditing result",})return}c.JSON(http.StatusOK, res)})// 启动服务器r.Run(":8080")
