补充一下,我用的加载方式是 protobuf.js中的
/**
* Fetches a resource.
* @param {string} path Resource path
* @param {function(?string)=} callback Callback receiving the resource’s contents. If omitted the resource will
* be fetched synchronously. If the request failed, contents will be null.
* @return {?string|undefined} Resource contents if callback is omitted (null if the request failed), else undefined.
* @expose
