今天是開始學go的第x天，前些日子看了看語言，今天找一個web開發(fā)來跟著學，記錄一下遇到的問題，方便以后復習查閱。

視頻看的是https://www.bilibili.com/video/BV1gJ411p7xC?p=3&vd_source=ab5bdbd04f4142027c66d604d5285204

?視頻中用的是goland，我用的vs

如何在vs中建一個項目：

這也是為了解決一個報錯：

go.mod file not found in current directory or any parent directory.'go get' is no longer supported outside a module.To build and install a command, use 'go install' with a version,like 'go install example.com/cmd@latest'For more information, see https://golang.org/doc/go-get-install-deprecationor run 'go help get' or 'go help install'.

因為下載gin的時候會報錯,就是這個命令：go get -u github.com/gin-gonic/gin

初次嘗試go寫一個網(wǎng)頁還是挺有意思的

package mainimport ("fmt""net/http"
)func sayHello(w http.ResponseWriter, r *http.Request) {_, _ = fmt.Fprintln(w, "Hello jzy")
}func main() {http.HandleFunc("/hello", sayHello)err := http.ListenAndServe(":9090", nil)if err != nil {fmt.Printf("http server failed, err:%v\n", err)return}
}
