Facebook注册插件在使用长/多个自定义字段登录FB后返回“无效客户端id”
我使用的FB注册插件代码如下：Facebook注册插件在使用长/多个自定义字段登录FB后返回“无效客户端id”,facebook,json,plugins,facebook-javascript-sdk,registration,Facebook,Json,Plugins,Facebook Javascript Sdk,Registration,我使用的FB注册插件代码如下： <html xmlns:fb="http://ogp.me/ns/fb#"> <script type="text/javascript"> window.fbAsyncInit = function() { FB.init({appId: 'xxx', status: true, cookie: true, xfbml: true}); }; (function() { var e = docum

感谢您对这一冗长描述的耐心 我对此没有任何修正，我只能提供一个可能的答案，不，我认为最有可能的解释是： 与所有其他插件一样，标签的作用基本上是在页面中创建一个iframe，它获取作为GET参数在查询字符串中传递的所有必要参数 因此，您为注册表单定义的许多字段意味着iframe的URL中有一个很长的查询字符串 问题是，浏览器限制了URL的可能长度–请参阅 web服务器也会这样做，在他们说“呃，这对我来说有点太多了，需要通过GET处理，所以很抱歉，但不抱歉…” 因此，虽然您的注册表单可能会在用户登录时定义许多字段，但因为iframe URL的长度不受浏览器或Facebook服务器的限制–如果用户未登录并单击登录按钮，则会通过Facebook身份验证流重定向，在成功登录后，他们应该“发送回”的URL注册表单的地址及其所有GET参数（在本例中）在Auth对话框URL中作为GET参数以及其他参数传输。当在另一个URL中作为GET参数传输URL时，必须应用URL编码，这会使它更加糟糕 这就产生了一个很长的URL，在浏览器或Facebook服务器的限制下，该URL无法再传输/处理。由于您收到Facebook的错误消息，在这种情况下，Facebook的服务器很可能拒绝处理该消息 因此，你可以尝试打开Facebook的bug报告——他们设置最大GET URL长度的限制可以解决这个问题；但如果他们愿意这样做，可能是另一个问题。因为允许更长的请求URL可能还有其他含义
即使他们这样做了，您的用户使用的浏览器可能仍然会遇到障碍–如果Internet Explorer中当前的URL路径部分限制仍然是2048个字符，那么这可能是下一个在前端出现多个字段的注册表的部分…谢谢，CBroe，详细的解释。我将重新编码，只获取Facebook表单上的基本字段，并在本地获取其余字段，而不是向Facebook寻求可能无法进行的更改。我感谢你的意见。
