集成方案
问题
1.Content Type使用错误，导致部分数据上传时丢失
在我们使用PutObjectRequest 获取上传进度得时需要设置文件类型
ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentType("text/plain");
ContentType属性指定响应的 HTTP内容类型。如果未指定 ContentType，默认为TEXT/HTML。
这里我们Content Type 如果没设对可能文件也能传上去，有的时候却不能，我现在还没发现什么规律（若有知道原因的可以留言里@我，有相关百度bos的问题也可以@我）
下面时我在网上整理的一些Content Type，大部分都能在这里找到（温馨提示：找的时候一定要ctrl+F）
