出现Mixed Content: The page at ‘＜URL＞‘ was loaded over HTTPS, but requested an insecure script ‘＜URL＞‘解决办法

When accessing a website, some web browsers may prompt unsafe pages and fail to display forms properly. The error code is as follows:

Mixed Content: The page at ‘＜URL＞‘ was loaded over HTTPS, but requested an insecure script ‘＜URL＞‘.

Cause analysis:

Google Chrome automatically blocks insecure HTTP links for HTTPS links, which is known as Mixed Content. When dynamically introducing HTTP resources in HTTPS pages, such as introducing a JS file, they will be directly blocked Requesting HTTP resources through AJAX on HTTPS pages will also be directly blocked.

Solution:

Just add a piece of code in the head of the corresponding page:

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

Kind reminder: Try to introduce it wherever you only need it, adding it casually may result in errors.
