go:遍历获取gin请求的所有参数

背景:为了提高程序的通用性,需要将前端request中请求的参数,包含表单参数全部取到.

 

代码:

func DataMapByRequest(c *gin.Context)(dataMap map[string]string,err error)  {
    //必须先解析Form
    c.Request.ParseForm()
    dataMap = make(map[string]string)
    //说明:须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]参数设置了[%d]次,只能设置一次.",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
}
