1.添加驗證碼
application Controller添加captcha()
public static void captcha() { Images.Captcha captcha = Images.captcha(); renderBinary(captcha);}
添加Route
GET /captcha Application.captcha
訪問 http://localhost:9000/captcha
驗證碼圖片已經(jīng)實現(xiàn)了，現(xiàn)在需要做的是驗證輸入信息與驗證碼一致
修改captcha()方法
public static void captcha(String id) { Images.Captcha captcha = Images.captcha(); String code = captcha.getText("#E4EAFD"); Cache.set(id, code, "10mn"); renderBinary(captcha); }
修改show()方法
public static void show(Long id) { Post post = Post.findById(id); String randomID = Codec.UUID(); render(post, randomID);}
修改show.html頁面
在Comment下方添加驗證碼圖片，和驗證控件
<p> <label for="content">Your message: </label> <textarea name="content" id="content">${params.content}</textarea> </p> <p> <label for="code">Please type the code below: </label> <img src="@{Application.catcha(randomId)}"> <br /> <input type="text" name="code" id="code" size="18" value="" /> <input type="hidden" name="randomId" value="${randomId}" /> </p> <p> <input type="submit" value="Submit your comment" /> </p>
2.驗證
修改postComment 方法
public static void postComment( Long postId, @Required(message="Author is required") String author, @Required(message="A message is required") String content, @Required(message="Please type the code") String code, String randomId) { Post post = Post.findById(postId); validation.equals(code, Cache.get(randomId)).message("Invalid code. Please type it again"); if(validation.hasErrors()) { render("Application/show.html", post); } post.addComment(author, content); Flash.success("Thanks for posting %s", author); Cache.delete(randomId); show(postId);}
修改show.html頁面
#{ifErrors} <p class="error"> ${errors[0]} </p> #{/ifErrors}
