使用极验验证码之前,我们先熟悉3个常用的接口。

是否开启验证码接口

接口名:/api3/account/captcha/open
http://localhost:8080/api3/account/captcha/open
参数非空:mobileNo;countryNo;
请求方式:get

预处理验证码接口

接口名:/api3/account/captcha/start
无参数:
请求方式:get

获取验证码接口

接口名:/api3/account/captcha/verify
参数非空:geetest_challenge,geetest_validate,geetest_seccode,
mobileNo,countryNo。
请求方式:post
{“success”:1,”gt”:”b46d1900d0a894591916ea94ea91bd2c”,”challenge”:”aca5d5a08c397aba47a973a1f968e9af”}
