The following column golang tutorial will introduce you to the advantages of the gin framework. I hope it will be helpful to friends in need!

Using the

function call stacklast-in-first-out feature to cleverly complete the post-processing operations completed by the middleware in the custom processing function.

Django's processing method is to define a class, define a method for processing before request processing, and define a method for processing after request processing.

gin's way is more flexible, but django's way is clearer.

Request parameter binding

For obtaining request content, in model binding, there are the following scenarios

Does the user need to care about the content of the request and choose a different binder?

The answer given in the gin framework for these scenarios is: Provide different methods to meet the above needs. The key point here still lies in the usage scenario.

// 自动更加请求头选择不同的绑定器对象进行处理
func (c *Context) Bind(obj interface{}) error {
    b := binding.Default(c.Request.Method, c.ContentType())
    return c.MustBindWith(obj, b)
}

// 绑定失败后，框架会进行统一的处理
func (c *Context) MustBindWith(obj interface{}, b binding.Binding) (err error) {
    if err = c.ShouldBindWith(obj, b); err != nil {
        c.AbortWithError(400, err).SetType(ErrorTypeBind)
    }

    return
}

// 用户可以自行选择绑定器，自行对出错处理。自行选择绑定器，这也意味着用户可以自己实现绑定器。
// 例如：嫌弃默认的json处理是用官方的json处理包，嫌弃它慢，可以自己实现Binding接口
func (c *Context) ShouldBindWith(obj interface{}, b binding.Binding) error {
    return b.Bind(c.Request, obj)
}
