# 其他伪代码
## 第三代验证码识别模式例子
访问
```
http://www.adidas.com.cn/captcha/ajax/getestStart/?t=1497062366111
```
得到验证码参数
```
{
success: 0,
gt: "0f6dcb26b411a6c0fd7d4a0ef5891dd3",
challenge: "7cbbc409ec990f19c78c75bd1e06f21532",
new_captcha: 1
}
```
由于这里的 `success: 0`, 所以使用 `&model=4`
请求识别
```
http://jiyanapi.c2567.com/shibie?gt=0f6dcb26b411a6c0fd7d4a0ef5891dd3&challenge=7cbbc409ec990f19c78c75bd1e06f21532&model=4&referer=http://www.adidas.com.cn&return=json&user=test&pass=test
```
识别成功
```
{
status: "ok",
challenge: "7cbbc409ec990f19c78c75bd1e06f21532",
validate: "a068849c0dabd81b9154f305145c7222"
}
```
## 第二代验证码伪代码
### 这里北京工商示例 此为伪代码，以供参考
```
#访问页面
返回文本 ＝ http.GET (“http://bj.gsxt.gov.cn/sydq/loginSydqAction!sydq.dhtml”)
#获取验证码参数
返回文本 ＝ http.GET (“http://bj.gsxt.gov.cn/pc-geetest/register”)
challenge ＝ Json (返回文本, “challenge”)
gt ＝ Json (返回文本, “gt”)
#{"success":1,"gt":"73a7e78f77d457e28a6ad4f12d4bb63e","challenge":"02254f9ffc17e3e1f7d44657431e477e"}
# 这里需要判断 success 的值,success=1无需设置,success=0设置为&model=1
#提交识别
返回文本 ＝ http.GET (“http://jiyanapi.c2567.com/shibie?user=test&pass=test&return=json&ip=>=” ＋ gt ＋ “&challenge=” ＋ challenge)
#识别成功返回结果,如果status为no 请重新获取验证码参数，重新识别。
# {
# status: "ok",
# challenge: "3d033f099597f5ae63e2e2c902301d183z",
# validate: "8f6ebd56291ed6569ac40c1d74780985"
# }
status ＝ Json (返回文本, “status”)
challenge ＝ Json (返回文本, “challenge”)
validate ＝ Json (返回文本, “validate”)
#验证验证码结果正确性
http.POST (“http://bj.gsxt.gov.cn/pc-geetest/validate”, “geetest_challenge=” ＋ challenge ＋ “&geetest_validate=” ＋ validate ＋ “&geetest_seccode=” ＋ validate ＋ “%7Cjordan”, , ))
# 没问题将会返回 {"status":"success","version":"3.3.0"} 如果有误请检查cookie是否处理好.
#提交查询得到正确结果
返回文本 ＝ http.POST (“http://bj.gsxt.gov.cn/es/esAction!entlist.dhtml?urlflag=0&challenge=” ＋ challenge, “nowNum=&keyword=aaa&urlflag=0&clear=%E8%AF%B7%E8%BE%93%E5%85%A5%E4%BC%81%E4%B8%9A%E5%90%8D%E7%A7%B0%E3%80%81%E7%BB%9F%E4%B8%80%E7%A4%BE%E4%BC%9A%E4%BF%A1%E7%94%A8%E4%BB%A3%E7%A0%81%E6%88%96%E6%B3%A8%E5%86%8C%E5%8F%B7”)
```
## 这里是需要传入gt和challenge的示例
```
返回数据 = get( "http://verify.panda.tv/captcha/get?app=pandatv&_=1462575041275" )
gt = 返回数据.gt
challenge = 返回数据.challenge
ret = get( "http://jiyanapi.c2567.com/shibie?gt=gt&challenge=challenge&referer=http://verify.panda.tv&user=test&pass=test&return=json" )
if( status == "ok"){
//识别成功
//返回结果,
{
status: "ok",
challenge: "3d033f099597f5ae63e2e2c902301d183z",
validate: "8f6ebd56291ed6569ac40c1d74780985"
}
}else if( status == "no"){
//无需理会,重新获取验证码参数提交
{
status: "no",
msg: "行为异常"
}
}else if( status == "stop"){
//请停止识别，并提示错误信息
{
status: "stop",
msg: "用户名不存在或密码错误"
}
}
```
