轨道放大器表单错误请求和响应访问控制允许源

Question

我正在使用 Rails amp 并为联系表单设置我的 AMP 路由

<form id='contactusform' method="POST" class="p2" action-xhr = "<%= addquery_path %>" custom-validation-reporting="as-you-go" target="_top">

</div>
<div submit-error>
<template type="amp-mustache">

</form>

我的控制器将表单保存在我的数据库中，但浏览器抛出错误。

def addquery
@contact = Lead.new
@contact.name = params[:name]
@contact.email = params[:email]
@contact.phone = params[:phone]
@contact.city = params[:city]
@contact.state = params[:state]
@contact.country = params[:country]
@contact.enquiry_type = params[:eventtype]
@contact.message = params[:message]
@contact.save
end

当我尝试提交我的 AMP 表单时，它会显示

AMP 表单错误请求必须具有access-control-allow-origin

在我的浏览器控制台中。

以及

响应必须具有access-control-allow-origin

Answer 1

在 rails 的表单处理程序中将access-control-allow-origin: <your domain>设置为响应标头。

例如，如果您在本地主机上运行，请将表单响应标头设置为access-control-allow-origin: http://localhost:3000
