能不能有个轻便易用的图形验证码包啊， ccap那个好难安装成功，对node版本也有限制，有什么别的好用的吗
页面 img#vcimg.pull-right(src=’/picvc?width=100&height=26’, alt=’#{lang.change}’, title=’#{lang.change}’)
JS $(’#vcimg’).click(function () { $("#vcimg").attr(‘src’, '/picvc?width=100&height=30&time= ’ +(new Date()).getTime()); });
Route get(’/picvc’, userController.getPicVC);
controller exports.getPicVC = function (req, res) { var width = !isNaN(parseInt(req.query.width)) ? parseInt(req.query.width) : 100; var height = !isNaN(parseInt(req.query.height)) ? parseInt(req.query.height) : 30; var code = parseInt(Math.random() * 9000 + 1000); req.session.picVCode = code; var p = new captchapng(width, height, code); p.color(180, 180, 180, 100); // First color: background (red, green, blue, alpha) p.color(parseInt(Math.random() * 255), parseInt(Math.random() * 255), parseInt(Math.random() * 255), 255);// Second color: paint (red, green, blue, alpha) var img = p.getBase64(); var imgbase64 = new Buffer(img, ‘base64’); res.writeHead(200, { ‘Content-Type’: ‘image/png’ }); res.end(imgbase64); };
大致这样，你可以参考一下 @wang-weifeng
