Context is the most important part. It allows us to pass variables between middleware, manage the flow, validate the JSON of a request and render a JSON response for example.

func (*Context) Abort 

func (c *Context) Abort()

Abort prevents pending handlers from being called. Note that this will not stop the current handler. Let's say you have an authorization middleware that validates that the current request is authorized. If the authorization fails (ex: the password does not match), call Abort to ensure the remaining handlers for this request are not called.

func (*Context) AbortWithStatus

func (c *Context) Bind(obj interface{}) error

Bind checks the Content-Type to select a binding engine automatically, Depending the "Content-Type" header different bindings are used: 

"application/json" --> JSON binding
"application/xml"  --> XML binding

otherwise --> returns an error. It parses the request's body as JSON if Content-Type == "application/json" using JSON or XML as a JSON input. It decodes the json payload into the struct specified as a pointer. It writes a 400 error and sets Content-Type header "text/plain" in the response if input is not valid.

Use X-Forwarded-For before X-Real-Ip as nginx uses X-Real-Ip with the proxy's IP. Notice: metadata.RemoteIP take precedence over X-Forwarded-For and X-Real-Ip
