阿里云STS临时授权访问OSS报NoSuchBucket

1.pom文件中添加依赖

		>
            >com.aliyun>
            >aliyun-java-sdk-sts>
            >3.0.0>
        >
        >
            >com.aliyun>
            >aliyun-java-sdk-core>
            >4.4.6>
        >

2写一个main方法，代码如下

String endpoint = "oss-cn-hangzhou.aliyuncs.com";
        String accessKeyId = "F-------DF";
        String accessKeySecret = "====81f";
        String roleArn = "acs:ram::===:role/ss";
        String roleSessionName = "roleSessionName";
        try {
            // 添加endpoint（直接使用STS endpoint，前两个参数留空，无需添加region ID）
            DefaultProfile.addEndpoint("", "", "Sts", endpoint);
            // 构造default profile（参数留空，无需添加region ID）
            IClientProfile profile = DefaultProfile.getProfile("", accessKeyId, accessKeySecret);
            // 用profile构造client
            DefaultAcsClient client = new DefaultAcsClient(profile);
            final AssumeRoleRequest request = new AssumeRoleRequest();
            request.setMethod(MethodType.POST);
            request.setRoleArn(roleArn);
            request.setRoleSessionName(roleSessionName);
//            request.setPolicy(policy); // 若policy为空，则用户将获得该角色下所有权限
            request.setDurationSeconds(1000L); // 设置凭证有效时间
            final AssumeRoleResponse response = client.getAcsResponse(request);
            System.out.println("Expiration: " + response.getCredentials().getExpiration());
            System.out.println("Access Key Id: " + response.getCredentials().getAccessKeyId());
            System.out.println("Access Key Secret: " + response.getCredentials().getAccessKeySecret());
            System.out.println("Security Token: " + response.getCredentials().getSecurityToken());
            System.out.println("RequestId: " + response.getRequestId());
        } catch (ClientException e) {
            System.err.println("Failed：");
            System.err.println("Error code: " + e.getErrCode());
            System.err.println("Error message: " + e.getErrMsg());
            System.err.println("RequestId: " + e.getRequestId());
        }

3.运行上面main方法，进入catch中，Error code:NoSuchBucket
4.解决办法
由于粗心，将endpoint写为了"oss-cn-hangzhou.aliyuncs.com",
官方提供的为：“sts.cn-hangzhou.aliyuncs.com”
或者写为"sts.aliyuncs.com"
