Facebook og数据未更新 [英] facebook og data not updating
问题描述
我已经创建了一个带有订阅的Facebook应用.
当用户打开应用程序时，会有一个名为"SUBSCRIBE"的按钮.单击时，将调用javascript函数completePayment().出现带有订阅的Facebook弹出窗口.但是，这是一个大问题.如果我更改og:image URL，并将价格设置为10.00 USD，将计费周期设置为1个月，然后将该文件上传到服务器，然后单击SUBSCRIBE按钮，我仍然可以看到订阅页面显示5.00美元/周，图像为空白.
即使我从 这是" https://www.mydomain.com/_product.php "页面:
facebook页面上有一个关于共享内容的缓存(如果不是半永久性的话):
可能有3种选择: 1)尝试清除以下页面上的页面缓存: https://developers.facebook.com/tools/调试
但是下次共享页面时您会遇到同样的问题 2)在您的网址中添加动态参数( https://www.mydomain. com/_product.php?q = 123 )，那么您将拥有与此网址相关联的唯一值，但是您需要使用参数php_get为该特定网址设置og.如果您没有什么价值，则可以手动进行设置；另一方面，如果您有更多价值或动态价值，则需要一个数据库表来存储带有链接URL和相关og的数据，并在php_get
3)通过重新抓取以编程方式清除缓存.请参阅: https://developers.facebook.com/docs/payments /product?locale = zh_CN#scraping-object 我在网站上做过类似的事情，但只是使用随机生成的值: http://www.paris-web.it/test.html I have created a facebook app with subscription. When the user opens the app, there is a button called "SUBSCRIBE". When it is clicked, the javascript function completePayment(), is called. The facebook popup with subscribe appears. However, there is a big problem. If I change the og:image URL and set the price to let's say 10.00 USD and the billing period to 1 month and I upload the file to the server and then I click on the SUBSCRIBE button, I can still see the subscription page saying 5.00 USD/week and the image is blank. It's like everything remained the same way that it was when I first set the data, even though I updated all the data from https://www.mydomain.com/_product.php , with the new values. I even logged out and relogged in, and still no changes are reflected. I even emptied the _product.php page and uploaded it to the server and the subscription still works and shows 5.00 USD/week and the image is blank. Any ideas on how to fix this? I have this code on the main page: This is the HTML code from the 'https://www.mydomain.com/_product.php' page:
The facebook page have a looong if not semi permanent cache about share content:
3 options are possible: 1) try to clear the page cache on: https://developers.facebook.com/tools/debug
but you will fall in the same problem next time you share the page 2) add a dynamic parameter to your url (https://www.mydomain.com/_product.php?q=123), than you will have a unique value associated with this url, but you need to set the og for this specific url with a php_get on the parameter. If you have few value you can make it manually, on the other hands if you have more value or dynamic value you need a DB table to store the data with the link url and the associated og and get the value in the php_get 3) Clear the cache programatically by re-scraping it. See: https://developers.facebook.com/docs/payments/product?locale=en_GB#scraping-object I've done somthing similar on my site but only with random generated value: http://www.paris-web.it/test.html 这篇关于Facebook og数据未更新的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！<html>
