如何使用golang通过邮递员以短方式获取表单数据？

Question

I am retrieving form data using postman, but the code is too long. Is there is any method for getting the data in short form? Here's the code I am using:

Customer struct:

type Customer struct {
 FirstName        string `json:"first_name" bson:"first_name"`
 LastName         string `json:"last_name" bson:"last_name"`
 Email            string `json:"email" bson:"email"`
}  
type Customers []Customer

type new_user struct {
 first_name     string 
 last_name      string 
 email          string
}

Function for retrieving the form data called by the route:

function GetData(c *gin.Context){
 first_name := c.PostForm("first_name")
 last_name := c.PostForm("last_name")
 email := c.PostForm("email")
 reqBody := new(new_user)
 err := c.Bind(reqBody)
 if err != nil {
    fmt.Println(err)
 }
 customer.FirstName = first_name
 customer.LastName = last_name
 customer.Email = email
}

I'm getting 3 form values. Suppose I need to get 50 values, then the function will be much bigger.

As the mkopriva tells me a short way to do this. I got the answer for it. It can be shorter by doing the following code.

type Customer struct {
 FirstName string `form:"first_name" json:"first_name" bson:"first_name"`
 LastName  string `form:"last_name" json:"last_name" bson:"last_name"`
 Email     string `form:"email" json:"email" bson:"email"`
}

In the function the code is:-

customer := new(Customer)
if err := c.Bind(customer); err != nil {
    return nil, err
}
fmt.Println(customer)

It will print the data from the form-data of the postman.
