nosurf 是 Go 语言的一个 CSRF 跨站请求伪造(Cross Site Request Forgery) 中间件，可嵌入到 net/http 中使用，可方便与 Gorilla 和 Martini 框架结合使用。
示例代码：
package main import ( "fmt" "github.com/justinas/nosurf" "html/template" "net/http" ) var templateString string = ` <!doctype html> <html> <body> {{ if .name }} <p>Your name: {{ .name }}</p> {{ end }} <form action="/" method="POST"> <input type="text" name="name"> <!-- Try removing this or changing its value and see what happens --> <input type="hidden" name="csrf_token" value="{{ .token }}"> <input type="submit" value="Send"> </form> </body> </html> ` var templ = template.Must(template.New("t1").Parse(templateString)) func myFunc(w http.ResponseWriter, r *http.Request) { context := make(map[string]string) context["token"] = nosurf.Token(r) if r.Method == "POST" { context["name"] = r.FormValue("name") } templ.Execute(w, context) } func main() { myHandler := http.HandlerFunc(myFunc) fmt.Println("Listening on http://127.0.0.1:8000/") http.ListenAndServe(":8000", nosurf.New(myHandler)) }
