Question

当我在使用Compojure模板创建的Clojure Webapp项目中尝试使用POST方法时，我收到了“无效的防伪令牌”。

我研究过，Ring Middle ware创建了CSRF（跨站点请求表单）令牌，用于来自其他站点的经过身份验证的请求（使用已登录的其他人的凭据并访问不允许访问的页面）。

这些令牌是默认的，我们需要在我们的WebApp周围使用ring.middleware的wrap-params。无法获得更多。请帮忙！！如何摆脱无效的防伪令牌。

我的handler.clj文件是：

(ns jsonparser-webapp.handler
   (:require [compojure.core :refer :all]
        [compojure.route :as route]
        [jsonparser-webapp.views :as views])
   (:use [ring.middleware.params :only [wrap-params]])

(defroutes app-routes
  (GET "/" 
    [] 
    (views/home-page))
  (GET "/goto" 
    [] 
    (views/goto))
  (POST "/posted"
     {params :params} 
     (views/posted params))
  (route/not-found "Not Found"))

(def app
    (wrap-params app-routes site-defaults))

我的views.clj文件是

(ns jsonparser-webapp.views
   (:require [hiccup.page :as hic-p]
             [hiccup.form :as hf]))

(defn gen-page-head
  [title]
  [:head
     [:title title]])

(defn home-page
  []
  (hic-p/html5
      (gen-page-head "Json Parser Home.")
      [:h1 "Welcome."]
      [:p "Json Web App."]
      [:a {:href "http://localhost:3000/goto"} "Goto"]
      [:p (hf/form {:action "/posted" :method "POST"} 
             (hf/text-field "TextInput")    
             (hf/submit-button "Submit"))]))

(defn goto
  []
  (hic-p/html5
      (gen-page-head "Goto Page.")
      [:h1 "Hi."]
      [:p "Go where?"]))

(defn posted
   [{:keys [x]}]
   (hic-p/html5
      (gen-page-head "Posted.")
      [:h1 "You posted."]
      [:p x]))

在Eclipse CounterClockwise中使用Clojure的Compojure模板创建的项目。

您必须在表单中添加(anti-forgery-field)，以便将防伪令牌注入POST参数。

像这样：

(ns jsonparser-webapp.views
  (:require [hiccup.page :as hic-p]
>           [ring.util.anti-forgery :refer [anti-forgery-field]]
            [hiccup.form :as hf]))

(defn gen-page-head
  [title]
  [:head
   [:title title]])

(defn home-page
  []
  (hic-p/html5
    (gen-page-head "Json Parser Home.")
    [:h1 "Welcome."]
    [:p "Json Web App."]
    [:a {:href "http://localhost:3000/goto"} "Goto"]
    [:p (hf/form {:action "/posted" :method "POST"} 
         (hf/text-field "TextInput")    
 >       (anti-forgery-field)
         (hf/submit-button "Submit"))]))
