1，官方文档
https://docs.geetest.com/install/deploy/server/python
2，使用方法（基于flask）
1，从Github: gt3-python-sdk下载.zip文件，这个官方的压缩文件里面有三个demo，分别是基于django、flask、tornado实现的，可以作为参考。
我们需要这里面的 geetest.py 文件、gt.js文件。
2，在极验官网注册一个账号，获取公钥（id）、私钥（key），在后台代码中会用到。
3，后台代码
from flask import Blueprint,render_template,session,request
import random
from bul.u.geetest import GeetestLib
captach_id = "7982db09811fc65bb0172e65feda8181"
private_key = "e9d4fc300d39c013e85c631ed791af3b"
jc=Blueprint('jc',__name__)
@jc.route('/index')
def index():
return render_template('y.html')
@jc.route('/getcaptcha', methods=["GET"])
def get_captcha():
user_id = 'test'
gt = GeetestLib(captach_id, private_key)
status = gt.pre_process(user_id)
session[gt.GT_STATUS_SESSION_KEY] = status
session["user_id"] = user_id
response_str = gt.get_response_str()
return response_str
@jc.route('/validate', methods=["POST"])
def validate_capthca():
gt = GeetestLib(captach_id, private_key)
status = session[gt.GT_STATUS_SESSION_KEY]
challenge = request.form[gt.FN_CHALLENGE]
validate = request.form[gt.FN_VALIDATE]
seccode = request.form[gt.FN_SECCODE]
user_id = session["user_id"]
if status:
result = gt.success_validate(challenge, validate, seccode, user_id)
else:
result = gt.failback_validate(challenge, validate, seccode)
result = "success" if result else "fail"
return result
