我对这些协议感到困惑。在使用这些协议时可以使用哪些请求：

I am confused about these protocols. which requests are available in case of using these protocols:

• HTTP到HTTP


• HTTPS 到HTTP


• HTTP到 HTTPS


• HTTPS 到 HTTPS

• HTTP to HTTP
• HTTPS to HTTP

我在HTTPS中有一个域，在HTTP中有一个子域。我可以从 HTTPS 请求HTTP（POST和GET）来检索数据吗？

I have a domain in HTTPS and a sub-domain in HTTP. Can I request from HTTPS to HTTP (POST and GET ) to retrieve data?

$.getJSON('http://api.domainName.com/api/Visitor/GetStates/' + countryId, function(data) {
  $.each(data, function(key, value) {
    $("#StateId").html($("#StateId").html() +
      "<option value='" +
      value.StateId +
      "'>" +
      value.StateName +
      "</option>"
    );
  });
}

此请求来自：

我在子域中解决了CORS问题。
