/**
 * 上传文件
 *
 * 上传的本质：
 *
 * 1. 小程序上传文件是先用 chooseFile 获取一个文件，可以得到
 * 一个临时路径，然后用 uploadFile 上传该临时路径
 *
 * 2. H5 是 input 获取文件，然后用 FormData 上传 File 对象
 * @param {File} file 文件
 * @returns {Promise<{url: string}>} 上传结果
 *
 * @example
 * ```ts
 * import { uploadFile, UploadManager } from 't-comm/lib/uploader'
 *
 * uploadFile(file).then(() => {})
 *
 * // 可以通过 UploadManager 设置上传参数
 * UploadManager.setConfig({
 *   requestHashUrl: `https://${location.hostname}/pvp/share/getsharecfg.php`,
 *   uploadFileKey: 'upload_pic_input',
 *   uploadUrlPrefix: 'https://igame.qq.com/external/uploadpic.php?_hash=',
 * })
 *
 * // 可以通过 UploadManager.getInstance().updateHashCode 主动更新 hashCode
 * UploadManager.getInstance().updateHashCode();
 * ```
