本地结果

工作得很好

我不断得到

Refused to connect to 'http://d.biossusa.com/api/distributor?key=******' because it violates the following Content Security Policy directive: "connect-src 'self' https://* wss://*".

将我的 API 站点从 HTTP 转换为 HTTPS 可能有点昂贵。解决这个问题的方法是什么？

还有别的办法吗？

是否有任何框架或 API 可以帮助避免此错误？

Answer 1

从 HTTP 到 HTTPS 调用 URL 时 same origin policy将阻止您的请求。浏览器协议(protocol)作为不同来源处理。

例如，您可以使用 CORS启用跨源 HTTP 请求。使用 CORLS 将允许您发送请求从 HTTP 到 HTTPS。这是 good guide其中规定了使用 CORS 及其含义的基础知识。

大多数情况下，您需要通过将 Access-Control-Allow-Origin: * 添加到您的响应 header 来允许跨域请求。此配置将在您的后端应用程序(服务器端)中进行。但这此时对你没有帮助:

请注意，由于浏览器的安全功能，如果您从 HTTPS 到 HTTP 调用 URL，CORS/AJAX 请求将不起作用。看看 w3c access control security其中说:

As indicated as the first step of the cross-origin request algorithm and in the redirect steps algorithm user agents are allowed to terminate the algorithm and not make a request. This could be done because e.g.:

• The origin of the resource blacklisted.

• The origin of the resource is known to be part of an intranet.

• The URL is not supported. -https to http is not allowed.

• https is not allowed because of certificate errors
