如何解决Cherrypy中同源策略导致的跨域问题？
摘要：# 添加：cherrypy.response.headers["Access-Control-Allow-Origin"] = "*"
# 添加：
cherrypy.response.headers["Access-Control-Allow-Origin"] = "*"
cherrypy.response.headers["Access-Control-Allow-Methods"] = "GET, POST, OPTIONS"
cherrypy.response.headers["Access-Control-Allow-Headers"] = "Content-Type"
cherrypy.response.headers["Access-Control-Allow-Credentials"] = "true"
例如：
import cherrypy
import os
import subprocess
import change_format
class PreAnnoAsyncHandle:
@cherrypy.expose
@cherrypy.tools.json_out()
def index(self, scene_dir, frame, frame_num):
