Ati*_*lia 11 invisible recaptcha invisible-recaptcha
我们正在使用隐形reCaptcha,偶尔,谷歌的Javascript代码向Google的服务器发出请求,接收响应状态410,而不是200.
我们无法控制它,因为Google的reCaptcha Javascript代码提出了请求.
如果已向用户呈现挑战,则以下是失败请求的示例:
GET https://www.google.com/recaptcha/api2/payload?c=03AOPBWq_EYB...
响应是:
HTTP/1.1 410 Gone
<HTML>
<HEAD>
<TITLE>Gone</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Gone</H1>
<H2>Error 410</H2>
</BODY>
</HTML>
它失败了大约10%的时间.以下是HTTP请求的"历史记录":

这基本上是因为会话已过期。当您收到错误 410（即未成功，但您仍希望上传文件）时，您必须启动新会话。请查看以下链接了解详细信息： https://www.rfc-editor.org/rfc/rfc7231#section-6.5.9
