rucaptcha's Issues

Rails 关于验证码的 rucaptcha 的一点问题。为什么刷新只是刷新验证码的颜色没有改变数字和内容

刷新之后的验证码只有颜色改变没有改变数字

Invalid route name, already in use: 'ru_captcha' (ArgumentError)

部署使用生产环境，启动报错。在本地测试环境使用正常。不知是哪里有问题

routes.rb

  # rucaptcha
  mount RuCaptcha::Engine => "/rucaptcha"

Exiting

You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:

How to print the rucaptcha code?

I konw that in the form, I can use the method verify_rucaptcha? to verify the code, is there any way that I can print or get the rucaptcha code in the back-end?

verify_rucaptcha?

在本地调试，单步跟踪，发现 verify_rucaptcha?(@user) 一直返回false，请问可能是什么原因？

How can I disable cache_store warning on test env?

Keep getting this warning:

  RuCaptcha's cache_store requirements are stored across processes and machines,
  such as :mem_cache_store, :redis_store, or other distributed storage.
  But your current set is file_store, it has changed to :file_store for working.
  NOTE: :file_store is still not a good way, it only works with single server case.

  Please make config file `config/initializers/rucaptcha.rb` to setup `cache_store`.
  More infomation please read GitHub RuCaptcha README file.

The picture not shown completely

as mentioned in title, my verify code picture cannot show completely, as link followed:

http://standard.cfda.pub:8800/rucaptcha

my os system is centos 6.5, and rails version is: 4.2.4

Add sound or other accessibility feature

Would enable people to have an option other than using visual feedback. Example libraries with audio captcha include

https://gitee.com/chenhaohan88/captcha
https://github.com/dchest/captcha
It is also possible to add sound to a slider captcha. An example slider captcha is https://gitee.com/anji-plus/captcha

Happy to implement one of these.

翻译--小bug

简体和繁体的翻译放错文件了。

使用devise，当verify_rucaptcha? 后不跟resource参数时，resource.errors里还是出现error

你好：
我使用了devise，不想将验证码失败的error放在user里，想将注册时字段错误信息和验证码失败信息分开，所以想调用verify_rucaptcha? nil，如下例子：

class Users::RegistrationsController < Devise::RegistrationsController

  def create
    build_resource(sign_up_params)
    if verify_rucaptcha?
      resource.save
      yield resource if block_given?
      if resource.persisted?
        if resource.active_for_authentication?
          set_flash_message! :notice, :signed_up
          sign_up(resource_name, resource)
          respond_with resource, location: after_sign_up_path_for(resource)
        else
          set_flash_message! :notice, :"signed_up_but_#{resource.inactive_message}"
          expire_data_after_sign_in!
          respond_with resource, location: after_inactive_sign_up_path_for(resource)
        end
      else
        clean_up_passwords resource
        set_minimum_password_length
        respond_with resource
      end
    else
      #resource.errors.clear
      flash.now[:alert] = t('rucaptcha.invalid')
      clean_up_passwords resource
      respond_with resource
    end
  end
end

随后看了一下代码，应该是rucaptcha-2.5.0/lib/rucaptcha/controller_helpers.rb里的75行
add_rucaptcha_validation_error方法里resource引用的是全局resource，不是verify_rucaptcha?传进去的resource。

原来是在web里用的图形验证码，使用Grape的接口服务里怎么使用啊？

如何改变生成的验证码的长度

请问有没有方法去改变生成的验证码的长度？貌似这一块的生成逻辑时靠 rucaptcha.c 来实现的，有没有方法改一下？

点击验证码怎么刷新呢？需要另写js或jquery吗小白求教

vulnerability -> every next fresh session -> same initial captcha

Hello @huacnlee.
I noticed a bug that was produced with the following version:

rucaptcha (2.5.3)
  railties (>= 3.2)

After I've integrated rucaptcha for login form, every next visit with fresh browser history/cache the first generated captcha keeps being the same.

After researching the forks of your gem, I noticed that this bug is not reproduced with the following version:

GIT
  remote: https://github.com/insales/rucaptcha.git
  revision: 3fe084ee93b552393c961ec90cf08b10985048c5
  specs:
    rucaptcha (2.1.3)
      railties (>= 3.2)

Please consider pulling changes and let me know if you need assistance. The mentioned fork's master branch is

insales:master branch is 19 commits ahead, 38 commits behind huacnlee:master.
I can fork insales:master to rebase it on your huacnlee:master branch to create a pull request in case you are willing to merge but too busy to do this.

Please also let me know if the mentioned vulnerability is a result of gem misuse/misconfiguration.

imagemagick 的 convert 命令的版本:

Version: ImageMagick 6.7.2-7 2016-05-09 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC
Features: OpenMP

应用使用https的时候生成的链接还是http

生成的代码
<src="http://xxx.com">
产生警告
was loaded over HTTPS, but requested an insecure image 'http://www.xxx.com/rucaptcha/'. This content should also be served over HTTPS.

How change backgroud of image ?

exam : I want transparent backgroup , or need backgroup white or black . or more ?
How set ?

配置问题

在initializers/rucaptcha.rb文件中配置length和strikethrough无效。

支持子路径？？

我想使用这个gem .可是我的应用是在子路径上的，如 www.qq.com/xx/xx/,所以路由能不能自定义一下，让rucaptcha 支持子路径，/xx/xx/rucaptcha ?

imagemagick和imagemagick已经安装

如果配置文件设置为redis_store, 但并不启动redis，验证码能出来，但无法验证通过。

如果配置文件设置为redis_store, 但并不启动redis，验证码能出来，但一直无法验证通过。
这可能是个小问题。

理想的方式是：
配置文件设置为redis_store, 但连接不到redis，就使用file_store.

verify_rucaptcha? false

生成验证码的图片正常，verify_rucaptcha?(@user) 返回false，且@user上并没有:base的error

Readme 加上 centos 安装的支持

请在 readme 中的 required 中上添加：

Centos

sudo yum install -y ImageMagick ImageMagick-devel ghostscript

我在这个gem的基础上做了修改，需要合入吗

我引入这个gem后，用的人都反馈验证码看不太清，每次要输入四五次才能成功，所以我把这个验证码改成了 4 位，没有横线，看起来清晰很多。

我想合到你这边，不知道需不需要？

如何换成数字图形的验证码

华顺请教一下，如果验证码我想换成全是数字，不含字母的，应该怎么设置或改代码啊？谢谢

Windows上的rucaptcha image并没有出现

配置是 self.cache_store = :redis_store

有关的gem：

    gem 'rucaptcha', '~> 2.1.2'
    gem 'redis-rails'

报错信息是

调试后发现 gems/rucaptcha-2.1.2/app/controllers/ru_captcha/captcha_controller.rb

if Gem.win_platform?
  send_file data, opts
else
  send_data data, opts
end

如果是windows时，使用的send_file，修改为send_data就会正常显示图片了

我公司项目使用后，客户反应亮黄色不容易看清楚

建议把亮黄色去掉。

verify_rucaptcha? return false because store_info is nil

验证总是返回false，经过调试，发现 store_info = RuCaptcha.cache.read(rucaptcha_sesion_key_key) 中的store_info一直返回nil

找到之前的旧贴： #33 , 使用redis_rails这个gem，把session存到redis，store_info依然返回空。
console中尝试使用RuCaptcha.cache.read方法也能正确读出hash
verify_rucaptcha? 与 verify_rucaptcha?(resource) 方式使用也都是返回false

我的环境之前是 ruby2.4.4 和 rails 5.2.2.1，redis和web服务在同一台服务器上。

最近新开了一台服务器（旧服务器关停)，并将ruby升级到2.6.3，rails升级到5.2.3，redis使用内网连接（已确定可正常连接），就出现了这个问题。

更新2.0.0后默认显示没有安装dalli

全部按照官方的配置进行，但是在启动的时候后台报没有安装dalli。

日志如下:

Invalid message not shown

I am using this gem without devise, version == 2.1.3.

Not sure why but cannot get the invalid message. Just follow the instructions.
Now in order to get an error message, I have to manually add a line of code to make it happen.

    if verify_rucaptcha?(@user) && @user.save
      @user.send_activation_email
      redirect_to activate_user_url(@user)
    else
      # this one below
      @user.errors.add(:base, t('rucaptcha.invalid'))
      render :new
    end

在view中添加代码后，提示

undefined local variable or method `ru_captcha' for #<#Class:0xbc0a7e74:0xbc0a7424>

2.3.1 的 ruby 好像不能加载，2.3.0的可以

原本我是想在console 里直接 require，但发现执行不了，总是找不到文件。换到2.3.0，就可以了，是版本的问题吗？

在控制器中verify_rucaptcha?没有这个方法

版本

ruby 2.5.1
Rails 5.2.1

rucaptcha.rb配置用的

self.cache_store = :file_store

但是在控制器中报错，找不到verify_rucaptcha？这个方法

edge case in src of rucaptcha_image_tag

In development env. rucaptcha_image_tag will render

<img alt="Rucaptcha" class="rucaptcha-image" src="http://127.0.01:3000/rucaptcha/">

The src attribute include host info. It's ok in local machine.

Edge case: in a remote server, just run with development env and bind local address. use Nginx to listen to 80 and forward request.

rails server -b 0.0.0.0

In this case, the absolute path of Rucaptcha tag with not working.

Whether using the relative path of image would be better?

希望可提供 redis_store 的配置功能

如果配置了:redis_store，则会通过lookup_store获取一个cache的obj，但获取到的redis_store是默认配置，通常是指向127.0.0.1的，但如果这个redis_store不在::1上呢？

提供一个captcha ID 的接口会不会更好用？

先在captcha 的索引是通过rucaptcha_sesion_key_key 来存在session 里面的。但是如果是无状态的API 接口的话（移动端），就不太好用了。

像这样把captcha 在存储中的key 返回，就可以支持不用cookie 的API了

  def new_generate_rucaptcha
    res = RuCaptcha.generate()
    session_val = {
        code: res[0],
        time: Time.now.to_i
    }
    RuCaptcha.cache.write(rucaptcha_sesion_key_key, session_val, expires_in: RuCaptcha.config.expires_in)
    opts = { disposition: 'inline', type: 'image/gif', filename: rucaptcha_sesion_key_key }
    send_data  res[1], opts
  end

生成的图片只能是200*70的吗？怎么设置图片大小？

Cannot use :file_store in local development env.

I know it is reasonable config for you to make :mem_cache or :redis as a default cache way in production due to cross machines issue. However, if you can leave a :file_store option for develop mode, it will be convenient for developers in their local machine. cheers.
