How to show reason for error 422 in GO

Question

Lately I’m breaking my head too much to debug the POST and PUT requests where HTTP 422 error always occurs (Incorrect input format)

In my project I am using the GIN framework to make a JSON BIND sent from the front end. I needed to know which attribute of the structure is not in the proper format.

How do I print the validation errors?

I tried the following:

func postPerson(c *gin.Context) {

    var person models.Person
    c.BindJSON(&person)

    fmt.Print(c.Errors.Error())
}

Answer 1

I found that to show errors be 400 or 422 is possible to take from Bindjson. Would be more like this:

func postPerson(c *gin.Context) {

    var person models.Person
    err := c.BindJSON(&person)

    if err != nil {
       fmt.Print(err.Error())
    }
}
