程序代码如下：

public class UploadFileQiniu implements UploadFile{
    private UploadProperties.Qiniu properties;

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

    private UploadManager uploadManager= new UploadManager(cfg);

    public UploadFileQiniu(UploadProperties.Qiniu properties) {
        this.properties = properties;
    }
    @Override
    public String uploadFile(MultipartFile file) {
        Auth auth = Auth.create(properties.getAccessKey(), properties.getSecretKey());
       // String token = auth.uploadToken(properties.getBucket());
        String qiNiuToken = auth.uploadToken(properties.getBucket());
        String a = qiNiuToken.replace("\\s", "");
        String token = a.replace("\n", "");
        try {
            String originalFilename = file.getOriginalFilename();
            // 文件后缀
            String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));
            String fileKey = UUID.randomUUID().toString() + suffix;
            Response response = uploadManager.put(file.getInputStream(), fileKey, token, null, null);
            return properties.getDomain() + fileKey;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "error";
    }
}

问题解决了：
查看官方文档有这样的配置 设置请求协议为http

遂修改代码为

public class UploadFileQiniu implements UploadFile{
    private UploadProperties.Qiniu properties;
    //构造一个带指定Region对象的配置类
 private Configuration cfg = new Configuration(Region.huabei());
    private UploadManager uploadManager;
    public UploadFileQiniu(UploadProperties.Qiniu properties) {
        this.properties = properties;
    }
    @Override
 public String uploadFile(MultipartFile file) {
        cfg.useHttpsDomains = false;
        uploadManager= new UploadManager(cfg);
        Auth auth = Auth.create(properties.getAccessKey(), properties.getSecretKey());
       // String token = auth.uploadToken(properties.getBucket());
 String qiNiuToken = auth.uploadToken(properties.getBucket());
        System.out.println(qiNiuToken);
        try {
            String originalFilename = file.getOriginalFilename();
            // 文件后缀
 String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));
            String fileKey = UUID.randomUUID().toString() + suffix;
            Response response = uploadManager.put(file.getInputStream(), fileKey, qiNiuToken, null, null);
            return properties.getDomain() + fileKey;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "error";
    }
}

但是原理未知，
个人认为是，临时域名不支持hhtps访问，所以会出现ssl验证错误，改用http传输问题解决
