如若出现跨域问题，请绑定自定义域名，如若绑定自定义域名还是出现跨域问题，将结构化数据中的shuoshuo列表权限全部改成所有用户

用这个CF worker 试试

function rp(p) {
  return p.split("?")[0]

function l(p) {
  return p[getJsonLength(p) - 1]

function remove_protocol(domain){
  return domain.slice(8)

function getJsonLength(jsonData) {

  var jsonLength = 0;

  for (var item in jsonData) {

    resHEDNew.set("test-header", "9.99")
    var response = new Response(responsefetch.body, { headers: resHEDNew })
    return response
  },
};

workers 里面的环境变量配置如下

SERVERDOMAIN 变量以 https:// 开头

补充：我这边LearnCLoud 的配置里面配置了自定义域名
