Golang unmarshal type error without model mismatching-CodePudding

I have this response model

type CategoryDto struct {
    ID                int                    `json:"id"`
    Size              int                    `json:"size"`
    Rate              int                    `json:"rate"`
    Name              string                 `json:"name"`
    Komisyon          int                    `json:"komisyon"`
}

And expected response from client service as follows:

{
          "id": 1182,
          "size": 28,
          "rate": 8,
          "name": "Dress",
          "komisyon": 21
}

But when unmarshalling golang gives me error: unmarshal type error and shows; komisyon is the problem - number 21.0

When I changed komisyon int to interface{} it works but why golang gives me this error which is clearly is int. How to ensure other expected int values will be correct?

CodePudding user response：

It seems that your komisyon field is 21.0, it'is not a interger, you can change it to float64.

type CategoryDto struct {
    ID       int     `json:"id"`
    Size     int     `json:"size"`
    Rate     int     `json:"rate"`
    Name     string  `json:"name"`
    Komisyon float64 `json:"komisyon"`
}

you can print val to see what it's the before unmarshal it.

CodePudding user response：

you receiving float, change komisyon to float
