问题 To my shame, I have not been able to figure out how to get data from the frontend in Gin framework. In Django I get data So: user=request.data.get('user') print(user) Everything is simple and understandable as day. How should I do it in gin? user := c.Query("user") user := c.Param("user") user := c.Params.ByName("user") user := c.PostForm("user") println(user)//emptiness.... 回答1: Well, I'd say you should fetch some book/HOWTO on how HTTP work and spend some time with it because it appears you

问题 Using gin framework. Is there anyway to notify client to close request connection, then server handler can do any back-ground jobs without letting the clients to wait on the connection? func Test(c *gin.Context) { c.String(200, "ok") // close client request, then do some jobs, for example sync data with remote server. // } 回答1: Yes, you can do that.

问题 I have piece of code in which I get error when I use := but when I use = it compiles properly.

问题 I am trying to write a middleware where I will be doing a json schema validation against the request body. After the validation, I need to use the request body again. But I am not able to figure out how this can be done. I referred this post and found a way to access the body. But once the request body is used, I need that available to my next function. Here is the sample code: package main import ( "fmt" "io/ioutil" "net/http" "github.com/gin-gonic/gin" //"github.com/xeipuuv/gojsonschema" )
