// 如果没有axios需要安装axios
$ npm install axios -S
$ npm install vue-social-captcha -S
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
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"
}
