推荐答案
问题
您已将引荐政策设置为"no-referer-when- Nginx中的降级"，这意味着在降级(https提交到简单http)的情况下，不会发送引荐来源信息(作为您的表单网址).而且您背后的代码不喜欢没有这些信息.
Problem
You have the Referer Policy set to "no-referer-when-downgrade" in Nginx, which means referer information (as your form URL) is not sent in case of downgrade (httpS submitting to simple http). And your code behind doesn't like not having this piece of information.

最好是将所有内容传递给http s :)
将nginx.conf中的策略更改为:
Change in your nginx.conf, the policy to:
add_header 'Referrer-Policy' 'origin';
如果2.不起作用，请按照1.中所述进行操作，或者也可以(但是请 不要这样做，这是非常不安全的):
If 2. doesn't work, please do as said in 1., or you can also (but please don't do that, it's very unsecure):
add_header 'Referrer-Policy' 'unsafe-url';
