ReCaptcha在iPhone上无法正常工作
我有一个网站,有一个简单的联系表格。验证是最小的,因为它不会进入数据库;只是一封电子邮件。该表单的工作原理如下:
有 5 个字段 - 其中 4 个是必填字段。提交将被禁用,直到 4 个字段有效,然后您可以提交它。然后再次在服务器上验证所有内容,包括验证码(未由我客户端验证)。整个过程使用ajax完成,并且必须在服务器端通过多个测试,否则将返回4**标头,并调用失败回调处理程序。
一切都像桌面上的Chrome上的帮派破坏者一样工作(我没有尝试过其他浏览器,但我无法想象为什么它们会有所不同),但是在iPhone上,即使我没有选中测试框,reCaptcha也总是会进行验证。
换句话说:我仍然必须正确填写四个值才能提交,但是如果我不选中reCaptcha的框,请求仍然成功。
如果有人认为这会有所帮助,我可以发布一些代码,但似乎问题出在设备而不是代码上。有人对此有任何见解吗?
注意:如果这有帮助,服务器端是PHP / Apache。
更新日期: 5/28/2015:
我仍在调试这个问题,但似乎Mobile Safari正在忽略我在iPhone上的响应标头。当我将响应输出到页面时,我在桌面上获得的是:(data,status,xhr)
data
:我的回答,此时只是说错误或成功 ->error
status
:error
xhr
:{'error',400,'error'}
在移动野生动物园上:
data
:error
status
:success
xhr
:{'error',200,'success'}
所以 - 它似乎只是忽略了我的响应标头。我尝试明确设置,但无济于事。{"headers":{"cache-control":"no-cache"}}

根据请求,下面是代码。这几乎肯定比你需要的要多。它也变得更加迟钝,因为我进行了更改以尝试修复它。另请注意,虽然似乎有些变量尚未定义,但它们(应该)已在其他文件中定义。
