1: report action 得管理,  D:\opt\odoo15\addons\web\static\src\webclient\actions\action_service.js   line:1015

    async function _executeReportAction(action, options) {

        const handlers = registry.category("ir.actions.report handlers").getAll();  //注册一个报表处理把手集合, 后续代码出要扩展,就通过该这个对应的注册器 add 添加
　　　　　//循环处理所有句柄, 可知句柄可以传入三个参数 action, options, env
        for (const handler of handlers) {
            const result = await handler(action, options, env);
            if (result) {
                return result;
            }
        }
