Gin is a web framework written in Golang. It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
Something like:
type MyModel struct {
key string `json:"key" bindind:"dafult=5"`
}
Sorry: I'm newbie! And thank to anyone'll answer
How to use a type definition in another file with swaggo?
Using swaggo generate API document based on godoc syntax.
Source folder and files
|-post
|--controller.go
|--response.goFor this definition:
controller.go
package post
...
// Index godoc
// @Summary Index Post
// @Success 200 {array} []*Response
// @Router /v1/posts [get]
func Index(ctx *gin.Context) {
...
}The Response is been defined in an another file but the same package.
response.go
package post
// Response is post response body
type Response struct {
ID int64 `json:"id"`
Name string `json:"name"`
CreatedAt string `json:"created_at"`
UpdatedAt string `json:"updated_at"`
}But when run swag init to generate swagger docs, it said:
2021/01/29 09:39:56 Generate swagger docs....
2021/01/29 09:39:56 Generate general API Info, search dir:./
2021/01/29 09:39:56 ParseComment error in file application/post/controller.go :cannot find type definition:When I move the Response struct to controller.go, it works.
How to import it with godoc or swaggo?
Hi @Antonin72982395_twitter , I don't think you can have default values just like that, but you can do something like below
func NewResponse(data interface{}) Response {
// ... check nil and assign default values
}or as an extension function
func (r *Response) SetDefaults() Response {
// ... check nil and assign default values
}
Hi! One of my routes, /new-payment (this happens with all new routes) gets stuck on a redirect. My site goes from the URL http://localhost:8081/auth/new_payment_get to http://localhost:8081/new-payment, it’s missing /auth after the port and before the route (it should be redirected to http://localhost:8081/auth/new_payment_get). The POST route (http://localhost:8081/auth/new-payment) is supposed to be invoked when the user presses "submit" on a form on the "new_payment_get.html" page. Now it looks like http://localhost:8081/new_payment (it's supposed to be: http://localhost:8081/auth/new_payment_get.). The POST request registers on the server.
gin-gonic/gin#2675 causes the engine.prepareTrustedCIDRS to never execute if gin is not started via gin.RUN().
Our project uses http.Handler to start the service instead of gin.Run
but the front request still been blocked
Sorry wrong winow
any ideas of a middleware that allows you to add a timeout per request? Except for this one which is bugged: https://github.com/gin-contrib/timeout
Maybe I can find time this week to create one if you have trouble.
Can anyone help?
The main function,
sess := r.Group("/", pkg.EnableCookieSession())
{
sess.POST("/login", post.Login)

err := r.Run(":3333")
// err := r.RunTLS(":3333", "server.crt", "server.key")

My Login function,
func Login(c *gin.Context) {

c.String(http.StatusOK, "Login successful")
pkg.SaveAuthSession(c, username)
c.JSON(http.StatusOK, gin.H{"message": "Successfully authenticated user"})
}
My pkg.SaveAuthSession,
func SaveAuthSession(c *gin.Context, username string) {
session := sessions.Default(c)
session.Set("user", username)
err := session.Save()
if err != nil {
c.JSON(http.StatusInternalServerError, gin.H{"error": "failed to save session"})
}
c.JSON(http.StatusOK, gin.H{"message": "save session ok"})

func AuthSessionMiddle(c *gin.Context) {
session := sessions.Default(c)
sessionValue := session.Get("user")
if sessionValue == nil {
c.JSON(http.StatusUnauthorized, gin.H{

c.Abort()
return
}
// c.Set("userId", sessionValue.(uint))
c.Next()
return
}My problem is here, sessionValue := session.Get("user") won't get the session, I don't know why.
I am new to Go, can anyone help?
Thank you.
Thank you.
I am testing using the autotls with gin and I keep getting http: TLS handshake error from ... acme/autocert: missing server name
I am running with
err = autotls.Run(r, "api.myvaliddomain.com")
I am not exactly sure what the issue is, but I am running my gin app inside of docker with ports 80 and 443 forwarded
Hi :)
One of my Gin route handler starts a goroutine to handle the request in order to returns 200 asap (it's an event handler and the caller doesn't except any response).
I'm having a hard time testing that the goroutine is called, and testing what happens in it. Do you guys have any advice on the approach I should take?

I found https://stackoverflow.com/questions/51065482/how-to-test-if-a-goroutine-has-been-called-while-unit-testing-in-golang but it seems tricky to adapt to a Gin route handler

Hi everyone, Pooja here. I work as a Senior Marketing Coordinator at Packt. Looking at all the talk around Gin has encouraged me to share that Packt recently released a book on the framework.
