Use the gin framework to build a simple service

Go Language web Framework is very many, each has its own characteristics and style. The reason why I use the gin framework in my project is because the project started out as a martini, a well-designed framework, but there is a serious problem with too much use of reflection to make it too inefficient (the problem also caused the program to rise too fast in the event of traffic spikes), And this framework in the last year no one to maintain, and the author recommended the use of a very similar style of gin framework, probably looked at, the style is really similar, and high efficiency, so the use of gin. As for the other frameworks, it is beego that the project also uses its subproject beelog, but because the project I am doing is biased towards the application service rather than the website service, its style is more suitable for the website service, so there is no choice for it.

With these two frames on the GitHub warehouse, Martini doesn't recommend
Gin
Beego

Here's a quick code snippet for building a simple app service with gin, and it's easy to see the code comments.

Package Mainimport ("FMT"    "Github.com/gin-gonic/gin"    "Net/http") Func main () {gin. SetMode(Gin. DebugMode)//Global Settings environment, this is the development environment, the online environment is gin. ReleasemodeRouter: = Gin. Default()//Get route instance//Add middleware router. use(middleware)//Register interface router. GET("/simple/server/get", GetHandler) router. POST("/simple/server/post", Posthandler) router. PUT("/simple/server/put", Puthandler) router. DELETE("/simple/server/delete", Deletehandler)//Listening port HTTP. Listenandserve(": 8005", router)}func middleware (c *gin. Context) {FMT. Println("This is a middleware!")}func GetHandler (c *gin. Context) {value, exist: = C. Getquery("Key") if!exist {value ="The key is not exist!"} C. Data(http. Statusok,"Text/plain", []byte (FMT. Sprintf("Get success! %s\n ", value))) Return}func Posthandler (c *gin. Context{type jsonholder struct {Id int ' JSON:"id"' Name string ' JSON:"Name"'} Holder: = Jsonholder{id:1, Name:"My Name"}//If the JSON data is returned, you can use the Gin encapsulated JSON method C directly. JSON(http. Statusok, holder) Return}func Puthandler (c *gin. Context) {C. Data(http. Statusok,"Text/plain", []byte ("Put success!\n")) Return}func Deletehandler (c *gin. Context) {C. Data(http. Statusok,"Text/plain", []byte ("Delete success!\n")) return}

Access these interfaces with the Curl command to get the corresponding return result

Log output of the program

Here is just a quick way to get started, as a Web services framework, the function is certainly very powerful, which needs to be in the actual use of the slowly digging and drill down.
