Javascript：如何通過HTTPS和AJAX調用API？

Question

以前我的網站使用的是http協議，因此在我的JavaScript中可以正常運行：

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

但是由於http不安全，所以我轉向了HTTPS。 嘗試訪問HTTPS網站時應如何進行ajax調用？

順便說一句，我正在使用Flask API前面的Tornado Web服務器。 我的Tornado服務器代碼是這樣的：

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()

這是我每次Javascript（在AJAX中使用url：' https：// xxx：5000 / sthng '）調用API時都會在Tornado中遇到的錯誤：

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：執行curl給我這樣的事情：curl：（35）連接到xxx：5000的未知SSL協議錯誤

真的在這里迷路了！ 請幫忙。 謝謝。

嘗試將數據類型設置為“ jsonp”，這對跨域請求很有幫助。

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

不需要類型：ajax調用的get默認為'get'
