1 如何引用第三方滑动验证码

参考:极验科技:https://docs.geetest.com/install/deploy/server/python

1 安装requests

  pip install requests

2 拷贝你在网站上下载好的软件包下面的sdk下面的geetest文件到你的项目utils目录下面

3 拷贝代码到views.py

from utils.geetest import GeetestLib # 导入滑动验证码的模块
#请在官网申请ID使用,示例ID不可使用
pc_geetest_id = "b46d1900d0a894591916ea94ea91bd2c"
pc_geetest_key = "36fc3fe98530eea08dfc6ce76e3d24c4"

#pcgetcaptcha就是初始化(API1),获取流水标识并设置状态码

def pcgetcaptcha(request):
    user_id = 'test'
    gt = GeetestLib(pc_geetest_id, pc_geetest_key)
    status = gt.pre_process(user_id)
    request.session[gt.GT_STATUS_SESSION_KEY] = status
    request.session["user_id"] = user_id
    response_str = gt.get_response_str()
    return HttpResponse(response_str)

4 把二次验证的ap12放到登录函数的里面

 1 class LoginView(views.View):
 2     def get(self, request):
 3         return render(request, "login.html")
 4 
 5     def post(self, request):
 6         next_url = request.GET.get("next","/index/")
 7         username = request.POST.get("username")
 8         pwd = request.POST.get("password")
 9         # v_code=request.POST.get("vcode","").upper()  #如果用户不写验证码就是空
10         # 滑动验证码开始
11         gt = GeetestLib(pc_geetest_id, pc_geetest_key)
12         challenge = request.POST.get(gt.FN_CHALLENGE, '')
13         validate = request.POST.get(gt.FN_VALIDATE, '')
14         seccode = request.POST.get(gt.FN_SECCODE, '')
15         status = request.session[gt.GT_STATUS_SESSION_KEY]
16         user_id = request.session["user_id"]
17         if status:
18             result = gt.success_validate(challenge, validate, seccode, user_id)
19         else:
20             result = gt.failback_validate(challenge, validate, seccode)
21             #滑动验证码结束
22 
23 
24         # if v_code==request.session.get("v_code"):
25         if result:
26 
27             user_obj = auth.authenticate(username=username, password=pwd)
28             if user_obj:
29                 auth.login(request, user_obj)  # auth认证登录
30                 return redirect(next_url)
31             else:
32                 return render(request, "login.html", {"error_msg": "用户名或密码错误"})
33         else:
34             return render(request, "login.html", {"error_msg": "验证码错误"})

5  urls里面添加url

这个路径是上面api1的路径
url(r'^ooxx/$', views.pcgetcaptcha),

6 修改login登录页面代码

<script src="/static/plugins/jquery-3.3.1.min.js"></script>
{#<script src="/static/js/login.js"></script>#}
<!-- 引入封装了failback的接口--initGeetest -->
<script src="http://static.geetest.com/static/tools/gt.js"></script>
<!--滑动验证码的ajax操作-->
<script>
    var handlerEmbed = function (captchaObj) {
        $("#login-button").click(function (e) {
            var validate = captchaObj.getValidate();
            if (!validate) {
                $("#notice")[0].className = "show";
                setTimeout(function () {
                    $("#notice")[0].className = "hide";
                }, 2000);
                e.preventDefault();
            }
        });
        // 将验证码加到id为captcha的元素里,同时会有三个input的值:geetest_challenge, geetest_validate, geetest_seccode
        captchaObj.appendTo("#embed-captcha");
        captchaObj.onReady(function () {
            $("#wait")[0].className = "hide";
        });
        // 更多接口参考:http://www.geetest.com/install/sections/idx-client-sdk.html
    };
    $.ajax({
        // 获取id,challenge,success(是否启用failback)
        url: "/ooxx/?t=" + (new Date()).getTime(), // 加随机数防止缓存
        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: "embed", // 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
                // 更多配置参数请参见:http://www.geetest.com/install/sections/idx-client-sdk.html#config
            }, handlerEmbed);
        }
    });
</script>

7 修改存放验证码的div的id和button按钮的id,都要跟上面的js里面的一致

         <div class="form-group" id="embed-captcha">
                    <p id="wait" class="show">正在加载验证码......</p>
                    <p id="notice" class="hide">请先拖动验证码到相应位置</p>

          </div>
          
button按钮增加一个id名字跟上面的一致
<button type="submit" class="btn btn-success" id="login-button">登陆</button>
