Javascript：如何通过HTTPS和AJAX调用API？

Question

以前我的网站使用的是http协议，因此在我的JavaScript中可以正常运行：

$.ajax({
                    url: 'http://x.x.x:5000/sthng',
                    type: 'GET',
                    headers: {
                        "Authorization": "Basic " + btoa(uname + ":" + pass)
                    },
                    success: function(result) {
                        console.log(result)
                    }
                 });

但是由于http不安全，所以我转向了HTTPS。 尝试访问HTTPS网站时应如何进行ajax调用？

顺便说一句，我正在使用Flask API前面的Tornado Web服务器。 我的Tornado服务器代码是这样的：

from tornado.wsgi import WSGIContainer
from tornado.ioloop import IOLoop
from tornado.web import FallbackHandler, RequestHandler, Application
from flask-file import app
import tornado.httpserver

class MainHandler(RequestHandler):
  def get(self):
    self.write("This message comes from Tornado ^_^")

class getToken(tornado.web.RequestHandler):
    def get(self):
        self.write("hello")

tr = WSGIContainer(app)

application = Application([
(r'/', getToken),
(r"/tornado", MainHandler),
(r".*", FallbackHandler, dict(fallback=tr)),
])

if __name__ == "__main__":
  http_server = tornado.httpserver.HTTPServer(application, ssl_options={
        "certfile": "C:/x/key.pem",
        "keyfile": "C:/x/server.key",
  })
  http_server.listen(5000)
  tornado.ioloop.IOLoop.instance().start()

这是我每次Javascript（在AJAX中使用url：' https：// xxx：5000 / sthng '）调用API时都会在Tornado中遇到的错误：

ERROR:tornado.application:Exception in callback (<socket.socket fd=344, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('0.0.0.0', 5000)>, <function wrap.<locals>.null_wrapper at 0x000000000499FD90>) Traceback (most recent call last):

    ssl_options_to_context context.load_cert_chain(ssl_options['certfile'],
    ssl_options.get('keyfile', None)) ssl.SSLError: [SSL] PEM lib (_ssl.c:2515)

另外：执行curl给我这样的事情：curl：（35）连接到xxx：5000的未知SSL协议错误

真的在这里迷路了！ 请帮忙。 谢谢。

尝试将数据类型设置为“ jsonp”，这对跨域请求很有帮助。

  $.ajax({
        url: "https://x.x.x:5000/sthng/"
        dataType: "jsonp",
        success: function(data) {
          console.log(data)
        }
 });

不需要类型：ajax调用的get默认为'get'
