go:遍歷獲取gin請求的所有參數

背景:為了提高程序的通用性,需要將前端request中請求的參數,包含表單參數全部取到.

 

代碼:

func DataMapByRequest(c *gin.Context)(dataMap map[string]string,err error)  {
    //必須先解析Form
    c.Request.ParseForm()
    dataMap = make(map[string]string)
    //說明:須post方法,加: 'Content-Type': 'application/x-www-form-urlencoded'
    for key, valueArray := range c.Request.PostForm {
        if len(valueArray)>1{
            errMsg := fmt.Sprintf("#ERROR#[%s]參數設置了[%d]次,只能設置一次.",key,len(valueArray))
            return nil,errors.New(errMsg)
        }
        dataMap[key] = c.PostForm(key)
    }
    //
    for key,_ := range c.Request.URL.Query(){
        dataMap[key] = c.Query(key)
    }

    return
}
