Gin으로 더 나은 오류 처리를 구현하는 방법은 무엇입니까?

<code class="go">type appError struct {
    Code     int    `json:"code"`
    Message  string `json:"message"`
}</code>

<code class="go">func JSONAppErrorReporter() gin.HandlerFunc {
    return jsonAppErrorReporterT(gin.ErrorTypeAny)
}

func jsonAppErrorReporterT(errType gin.ErrorType) gin.HandlerFunc {
    return func(c *gin.Context) {
        c.Next()
        detectedErrors := c.Errors.ByType(errType)

        // Process errors and convert them to our custom error type
        if len(detectedErrors) > 0 {
            err := detectedErrors[0].Err
            parsedError := parseAPperror(err) 

            // Put error into response
            c.IndentedJSON(parsedError.Code, parsedError)
            c.Abort()
        }
    }
}</code>

<code class="go">func fetchSingleHostGroup(c *gin.Context) {
    hostgroupID := c.Param("id")

    hostGroupRes, err := getHostGroupResource(hostgroupID)

    if err != nil {
        c.Error(err)
        return
    }

    c.JSON(http.StatusOK, *hostGroupRes)
}</code>
