gin-gonic/gin

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.

TL;DR - I can't work binding for query parameter to check it is positive int, especially I have a problem with checking value numeric. The problem is that is simply doesn't work for me, so I strongly need advice :)

In my application I store a map of all my templates (map[string]*template.Template) in an ApplicationEngine struct, which is my application framework instance. I am currently using the standard context.Context to pass request scoped values between my middlewares and handlers. I need a way to access that map of templates in order to render a specific template file.

I was looking at the way gin handles this, and found that gin uses a custom struct that stores a pointer to gin.Engine, which is their application framework instance. It then has a HTML() function on the context struct, which accesses the template map stored in the gin.Engine pointer. Is there any specific reason that gin uses a custom struct instead of the standard context.Context? Some people seem to think that this is a bad idea.

Hello，

I want to ask a question about getting input parameters

type GetTxListIM struct {
    Page uint64 `form:"page" default:"1"`
    Rows uint8  `form:"rows" default:"10"`
    //ContractCall=1,Transfer=2,ContractCreation=3
    Type     []uint64 `form:"type"`
}

This is the structure content of the data I want to get

//@Param GetTxListIM query transaction_dto.GetTxListIM true "GetTxListIM"
//@Success 200 {object} transaction_dto.TxListOM
//@Failure 400 ""
//@Failure 500 ""
//@Router /Transaction/GetTransactionList [get]
func (controller *TransactionController) GetTransactionList(c *gin.Context) {
    var input transaction_dto.GetTxListIM
    if err := c.ShouldBind(&input); err != nil {
        log.Errorln(err)
    }
}

This is the Get method, here to parse the data

log:
{"level":"panic","msg":"strconv.ParseUint: parsing \"1,2\": invalid syntax","time":"2020-08-28 16:58:15"}

I am trying to create a route that will let me match the rest of the path portion of the relativePath as a .Param() I have r.PUT("template/:path", template.PutTemplate) and if I call it with template/path/to/my/template.txt I want .Param("path") to return path/to/my/template.txt is this possible?

Hello o/,

Is there any way to use multiple authentication middlewares for the same route ?
We use https://github.com/appleboy/gin-jwt and a custom auth middleware based on generated tokens in the database, but we're unable to set them for the same route. If someone has a solution or a workaround to be able to authenticate users from jwt token or from the generated token please.

what is the best practice to write middleware to handler error using gin-gonic ?

@cchang62

hi, gin-contrib/sessions. When I use and initiate redis as my session store, how can I get my session ID? I want to append this session ID to cookie, and then I can make a double verification on each http request or do other securities. No idea if I can assign an UUID to session name, and then get the session with the UUID in other place of web application? I also use go-gin as my base, by the way.

Currently I am serving my Vue frontend with a static route: r.Use(static.Serve("/", static.LocalFile("../frontend/dist", false)))
I would like to add the frontend in the compiled binary for easier deployment. I've tried to get it done with pkger but did not have any success. Any other idea?

@jLemmings You can use rice for example to achieve this. Check out -> https://github.com/gaia-pipeline/gaia/blob/master/Makefile#L21 for an example.

Or another one I really like is github.com/jessevdk/go-assets-builder

Gaia is using Vue so that should help you out a lot :)

go version
go1.15 linux/amd64
any help is appreciated
my manager is killing me 🤪🤪🤪
I found that it was possible with go version higher than 1.10 and looking at the v 1.15 it should be supported right?

Hi, please I need help. I have assets in vfsgen and using router.StaticFS(). That works well. But I would need for each request path ending with "/" (directory) return "/index.html" from vfs. Any idea please?

@qilx

I found it out. Solution is router.NoRoute() + c.DataFromReader()

Hi everyone!

I am very new developer and faced with such a problem while installing Gin on Ubuntu

/go/src$ go get -u github.com/gin-gonic/gin
package github.com/gin-gonic/gin: directory "/home/user/go/src/github.com/gin-gonic/gin" is not using a known version control system

Maybe someone knows the solution?

shyan

@shyan1

Have you had git installed on your machine ? @RaminCH
It's strange to have such issues.

RaminCH

@RaminCH

Hi @shyan1

Yup, Go_lev.2_RestAPI/Lec13$ git --version
git version 2.17.1

I even deleted and reinstalled

Also I installed Gin with: sudo apt-get install -y golang-github-gin-gonic-gin-dev
