安全验证（腾讯防水墙、极验行为验证）服务端开发及vue模板使用
截图
组件使用
1、安装
// 如果没有axios需要安装axios
$ npm install axios -S
$ npm install vue-social-captcha -S
2、使用
方法1：引入全局组件
在main.js引入组件
# main.js
import captcha from 'vue-social-captcha'
Vue.use(captcha)
在页面中使用
方法2：页面引入组件
直接在页面引入
3、参数
通过以下属性来设置你的验证码
4、返回值
相应数据格式
服务端返回参数主要有三个，分别是code msg data。
示例：
// 极验验证
{
"code":1,
"msg":"验证成功",
"data":
{
"success":1,
"gt":"29e4e065c7ba05ff77ba896e5d577f89",
"challenge":"bd26076b3afe9ed3c17738f3f8a7eec7",
"new_captcha":1
}
}
// 腾讯验证
{
"code":1,
"msg":"验证成功"
}
服务端接口示例
腾讯：
HttpRequestUtil为发请求工具类，Json处理为alibaba的fastjson，Result只是一个返回结果的封装
public Result> authentication(@RequestParam Map map) {
String aid= map.get("aid");
String aid= map.get("AppSecretKey");
String gType = map.get("g_type"); //验证码类型
String gScene = map.get("g_scene"); //验证码使用场景
String ticket = map.get("ticket"); .//票据
String randstr = map.get("randstr");//随机串
String ipStr = map.get("ipStr");// 客户端ip
String params = "aid="+aid+"&AppSecretKey="+AppSecretKey+"&Ticket="+ticket+"&Randstr="+randstr+"&UserIP"+ipStr;
String result = HttpRequestUtil.sendGet(baseUrl, params);
JSONObject jsonObject = JSONObject.parseObject(result);
String response = jsonObject.getString("response");
String err_msg = jsonObject.getString("err_msg");
String evil_level = jsonObject.getString("evil_level");
if(!"1".equals(response)){
return new Result>().error(0, err_msg);
}
Map resultMap = new HashMap<>(3);
resultMap.put("response", response);
resultMap.put("evil_level", evil_level);
resultMap.put("err_msg", err_msg);
Result> requestResult = new Result<>();
requestResult.setCode(1);
requestResult.setMsg("验证成功");
requestResult.setData(resultMap);
return requestResult;
}
