篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用阿里云服务器，能不能直接映射文件夹到OSS相关的知识，希望对你有一定的参考价值。
1、Sync4oss的文件同步工具不走FTP协议，利用操作系统的监测机制，高效获取磁盘文件变化情况，然后实时同步到OSS，直接从Sync4oss工具传到OSS，无需中转，性能效率高；2、您的图片不能显示，我个人分析是你的配置不正确（软件配置或者网站配置），和FTP应该是没有关系的，因为FTP只是一个帮你把图片传到OSS的工具而已；（基于我们的FTP云工具分析） 参考技术A 你可以用阿里云的幸运券，便宜不少，可分享给你。 参考技术B 不能的，，，，不能直接映射。。。。。
微信小程序直接上传文件到阿里云OSS组件封装
微信小程序直接上传文件到OSS
1. 封装公共方法
在根目录utils目录新建一个upload文件夹：
