一、问题描述

最近使用aliyun提供的java的CDN接口API来刷新缓存，导入其aliyun-java-sdk-2.2.3.jar和aliyun-java-sdk-core-3.0.6.jar后(更多aliyun依赖包和源码下载)，进行测试报“com.aliyuncs.exceptions.ClientException: SDK.InvalidRegionId : Can not find endpoint to access.”异常问题，具体内容如下

com.aliyuncs.exceptions.ClientException: SDK.InvalidRegionId : Can not find endpoint to access.@b@    at com.aliyuncs.DefaultAcsClient.doAction(DefaultAcsClient.java:180)@b@    at com.aliyuncs.DefaultAcsClient.doAction(DefaultAcsClient.java:143)@b@    at com.aliyuncs.DefaultAcsClient.doAction(DefaultAcsClient.java:59)@b@    at com.xwood.cdn.AliyunCDNUTest.describeRefreshQuota(AliyunCDNUTest.java:133)@b@    at com.xwood.cdn.AliyunCDNUTest.main(AliyunCDNUTest.java:148)

二、解决方法

之前在初始化方法init()在初始化客户端Profile没有配置正确的区域参数，如上面的接入点Endpoint配置的为“cn-hangzhou”,如下图所示，还有“c-shenzhen”..."cn-shanghai"
