3.渲染存储文件 · golang

模板渲染存储文件 (index.html同模板渲染终端index.html保持不变) ~~~ package main import ( "os" "fmt" "html/template" // "io" "net/http" ) var myTemplate *template.Template type Person struct { Name string age string } func userInfo(w http.ResponseWriter,r *http.Request) { p := Person{Name:"Murphy",age:"28"} myTemplate.Execute(os.Stdout,p) file,err := os.OpenFile("demo.dat", os.O_CREATE|os.O_WRONLY, 0755) if err != nil { fmt.Println("open failed err:", err) return } myTemplate.Execute(file,p) } func initTemplate(fileName string) (err error){ myTemplate,err = template.ParseFiles(fileName) if err != nil{ fmt.Println("parse file err:",err) return } return } /* func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) { DefaultServeMux.HandleFunc(pattern, handler) } */ func main() { initTemplate("./index.html") http.HandleFunc("/user/info", userInfo) err := http.ListenAndServe("0.0.0.0:8880", nil) if err != nil { fmt.Println("http listen failed") } } ~~~ 命令行： $ go run main.go 然后在浏览器中输入 : http://localhost:8880/user/info 命令行显示： ~~~ <html> <head> <title> </title> </head> <body> <p> hello,Murphy {Murphy 28} </p> </body> </html> ~~~ 命令行： control+c ^Csignal: interrupt $ ls demo.dat index.html main.go $ cat demo.dat ~~~ <html> <head> <title> </title> </head> <body> <p> hello,Murphy {Murphy 28} </p> </body> ~~~
