JS制作圖形驗(yàn)證碼實(shí)現(xiàn)代碼

更新時(shí)間：2020年10月19日 09:21:09 作者：qq_24147051

這篇文章主要為大家詳細(xì)介紹了JS制作圖形驗(yàn)證碼實(shí)現(xiàn)代碼，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

第一步我們來(lái)到要展示驗(yàn)證碼的頁(yè)面，當(dāng)我們按下?tīng)I(yíng)業(yè)執(zhí)照的時(shí)候讓其，彈出一個(gè)彈框，彈框的上面就是驗(yàn)證碼，如圖一所示：

（圖一）

彈框的樣式如圖二所示：

（圖二）

我們要對(duì)驗(yàn)證碼的值進(jìn)行校驗(yàn)，判斷驗(yàn)證碼是否輸入正確，當(dāng)輸入不正確的時(shí)候，我們提示錯(cuò)誤信息，提示信息如圖三所示：

（圖三）

如果頁(yè)面了驗(yàn)證正確，這不會(huì)提示錯(cuò)誤信息并且調(diào)到我們的目標(biāo)頁(yè)面，如圖四所示：

  //1-在路由層進(jìn)行設(shè)置，頁(yè)面跳轉(zhuǎn)到根目錄下/buyer/vshop/info.ejs頁(yè)面進(jìn)行跳轉(zhuǎn)，然后在回調(diào)函數(shù)中進(jìn)行接口的調(diào)用
  router.get('/buyer/vshop/info', function(req, res, next) { 
  //2-調(diào)用接口獲取數(shù)據(jù) 
  async.parallel({ 
  verifycode :function(fn){
  //3-調(diào)用接口獲取本機(jī)的IP地址
   var args= {
   userIp: tools.getClientIp(req)
   };

   //4-調(diào)用接口verifyCodeHelper的createVcode方法獲取captcha與 csnonce的數(shù)據(jù)，他們的值都是騰訊接口verifyCodeHelper返回的數(shù)據(jù)

   verifyCodeHelper.createVcode(args, function(err, result){
   if (err) {
    console.log(err);
   }
   else{
    fn(null, {
    captcha: result.data.queryUrl,
    csnonce: result.csnonce || 0
    })
   }
   });
  }
  },function(err, result){
  if (err) {
   res.end(err);
  }else{
   result.getDetail= res.shopInfo;
   var fxzStatus = res.fxzStatus || {};

  //5-進(jìn)行根目錄下buyer/vshop/describe頁(yè)面的渲染，傳遞相關(guān)參數(shù)到EJS頁(yè)面

   res.render("buyer/vshop/describe", { 
   title: srcBizType==1 ? result.getDetail.name : "店鋪簡(jiǎn)介",
   pageName:"vshopInfo",
   captcha:result.verifycode.captcha,//驗(yàn)證碼
   isTencent: 1,
   csnonce:result.verifycode.csnonce
   });
  }
  });
 });
