python极验验证部署

1、官方下载文档

　　https://github.com/GeeTeam/gt3-dotnet-sdk

2、下载极验官方geetest包

pip install geetest

3、根据不同开发环境选择对应文档包，以Django为例：

　　Ajax方式验证：

<script>
    var handlerPopup = function (captchaObj) {
        captchaObj.onSuccess(function () {
            var validate = captchaObj.getValidate();
            var $spanEle = $('.error')
            $.ajax({
                url: "/login_geetest/",  //第二次校验，验证用户名密码
                type: "post",
                dataType: "json",
                data: {
                    username: $('#inputUser').val(),
                    password: $('#inputPassword').val(),
                    geetest_challenge: validate.geetest_challenge,
                    geetest_validate: validate.geetest_validate,
                    geetest_seccode: validate.geetest_seccode
                },
                success: function (msg) {
                    if (msg.state == 1) {
                        $spanEle.text(msg.error)
                        $spanEle.parent().parent().addClass(msg.class)
                    } else {
                        {##结合auth模块的登录校验装饰器，获取需要访问url路由地址，实现登陆成功后，重定向到该地址#}
                        var url = location.search
                        if (url.indexOf("?") != -1) {
                            var str = url.substr(1);
                            strs = str.split("=");
                            location.href = strs[1];
                        } else {
                            location.href = '/index/';
                        }
                    }

                }
            });
        });
        $("#login").click(function () {
            captchaObj.show();
        });
        // 将验证码加到id为captcha的元素里
        captchaObj.appendTo("#popup-captcha");
    };
    // 验证开始需要向网站主后台获取id，challenge，success（是否启用failback）
    $.ajax({
        url: "/geetest/register?t=" + (new Date()).getTime(), // 加随机数防止缓存， 第一次校验，验证极验图片
        type: "get",
        dataType: "json",
        success: function (data) {
            // 使用initGeetest接口
            // 参数1：配置参数
            // 参数2：回调，回调的第一个参数验证码对象，之后可以使用它做appendTo之类的事件
            initGeetest({
                gt: data.gt,
                challenge: data.challenge,
                product: "popup", // 产品形式，包括：float，embed，popup。注意只对PC版验证码有效
                offline: !data.success, // 表示用户后台检测极验服务器是否宕机，一般不需要关注
                new_captcha: data.new_captcha
            }, handlerPopup);
        }
    });
</script>
