Try to install a little gin, some small problems to record what
installation steps
- First, let's look at the official documents, links point where
you can see the installation procedure is very simple, just a word
go get -u github.com/gin-gonic/gin
Enter the phrase runs like waiting on the command line.
- The question is, since the issue of the wall, go get will be very slow, so the command line inside for a long time nothing happened, do not worry, it will slowly waiting to see gin-gonic / gin this directory appears
- This time the command line is still not over, still represents some stuff. Sometimes people may be impatient stopped (like me), then write a simple example to test whether the installation was successful
package main
import (
"github.com/gin-gonic/gin"
)
func sayhello(c *gin.Context) {
c.JSON(200, gin.H{
"message": "hello go gin!",
})
}
func main() {
r := gin.Default() //默认的路由引擎
r.GET("/hello", sayhello) //get请求访问时执行sayhello
//启动服务
r.Run(":9090")
}
Run will prompt being given that the lack of yaml, locales ......
- The key to the place, because go get too slow, so I went to search for solutions that go mod + basic proxy settings, or change the hosts git clone, I try to look at git clone is the least expensive and effective, what is missing running time will be prompted to lack github / xxxx / xxxx, so long as the corresponding folder git clone down relevant documents like, yesterday forget because the screenshots so here we need to make up their own brain a little longer. I seem to remember git down is yaml, and then rename themselves yaml.v2, again try to run this example.
Successful operation, a subsequent general environmental well start learning fun again.
