返回的json如下 ：
{"loan_product_id":"101","manage_rate":"0.41","overdue_rate":"0.09","late_fee_rate":"0.00"}
type OrderRet struct {
ProductId int `json:"loan_product_id,int"`
OverdueRate float64 `json:"overdue_rate,string"` //
MangeRate float64 `json:"manage_rate,string"`
LateFeeRate float64 `json:"late_fee_rate,string"`
}
比如 OrderRet 结构体里边的 ProductId 类型是int, tag是int 但是json返回是string类型。报错为
cannot unmarshal string into Go struct field OrderRet.loan_product_id of type int
情况2 返回的json是int，struct里边的tag是其他类型比如是string.则报错返回的josn
{"loan_product_id":101,"manage_rate":"0.41","overdue_rate":"0.09","late_fee_rate":"0.00"}
type OrderRet struct {
ProductId int `json:"loan_product_id,string"`
OverdueRate float64 `json:"overdue_rate,string"` //
MangeRate float64 `json:"manage_rate,string"`
LateFeeRate float64 `json:"late_fee_rate,string"`
}
或者结构体
type OrderRet struct {
ProductId string `json:"loan_product_id,string"`
OverdueRate float64 `json:"overdue_rate,string"` //
MangeRate float64 `json:"manage_rate,string"`
LateFeeRate float64 `json:"late_fee_rate,string"`
}
ProductId string `json:"loan_product_id,string"` 类型是 int或者 string,但是tag的与json的int不一样，这里的tag是string
比如 OrderRet 结构体里边的 ProductId 类型是int, tag是string 但是json返回是int类型。报错为
invalid use of ,string struct tag, trying to unmarshal unquoted value into string
