maven工程写的小demo

需要注意的你的区别选错了

如果用错了的话，一般给的提示就是

{ResponseInfo:fo:com.qiniu.http.Response@5b7@5b792f7e,status:400, reqId:2Q0AADhOEv7T8F4V, xlog:UP:4/400, xvia:, adress:ss:up-z2.qiniu.com/183.236.51.11:80, dur duration:0.000000 s, error:incorrect region, please use se up-z1.qiniup.com}
{"}
{"error":"incorrect region, please use se up-z1.qiniup.com"}"}

请看please use se up-z1.qiniup.com，请用z1，这里是因为你的存储空间在华北区，所以自己选一下，对应到代码的话，在这个位置，给zone2改成zone1

// 构造一个带指定Zone对象的配置类
Configuration cfg = new Configuration(Zone.zone2());
