第一步我们来到要展示验证码的页面，当我们按下营业执照的时候让其，弹出一个弹框，弹框的上面就是验证码，如图一所示：
（图一）
弹框的样式如图二所示：
（图二）
我们要对验证码的值进行校验，判断验证码是否输入正确，当输入不正确的时候，我们提示错误信息，提示信息如图三所示：
（图三）
如果页面了验证正确，这不会提示错误信息并且调到我们的目标页面，如图四所示：
（图四）
路由层描述
/**
供货商店铺－店铺简介
*/
//1-在路由层进行设置，页面跳转到根目录下/buyer/vshop/info.ejs页面进行跳转，然后在回调函数中进行接口的调用
router.get('/buyer/vshop/info', function(req, res, next) {
//2-调用接口获取数据
async.parallel({
verifycode :function(fn){
//3-调用接口获取本机的IP地址
var args= {
userIp: tools.getClientIp(req)
};
//4-调用接口verifyCodeHelper的createVcode方法获取captcha与 csnonce的数据，他们的值都是腾讯接口verifyCodeHelper返回的数据
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-进行根目录下buyer/vshop/describe页面的渲染，传递相关参数到EJS页面
res.render("buyer/vshop/describe", {
title: srcBizType==1 ? result.getDetail.name : "店铺简介",
pageName:"vshopInfo",
captcha:result.verifycode.captcha,//验证码
isTencent: 1,
csnonce:result.verifycode.csnonce
});
}
});
