1. 获取AK和SK

   
   

2.新建存储空间

3.获取空间的默认域名 该域名可配置

3.引入maven依赖

<dependency>
    <groupId>com.qiniu</groupId>
    <artifactId>qiniu-java-sdk</artifactId>
    <version>[7.2.0, 7.2.99]</version>
</dependency>

4. 直传文件

public static void main(String[] args) {
    String ak = "5BTWCnr5NBGUD************************";
    String sk = "2V_zzBQCZbRahe4************************";
    String bucket = "test";
    String token = Auth.create(ak, sk).uploadToken(bucket);
    // 0华东 1华北 2华南  Na0北美
    Configuration cfg = new Configuration(Zone.zone2());
    UploadManager uploadManager = new UploadManager(cfg);
    try {
        byte[] fileBytes = FileUtil.readBytes("D:\\img.jpg");
        Response put = uploadManager.put(fileBytes, "first.jpg", token);
        // put.bodyString() 响应json字符串
        DefaultPutRet defaultPutRet = put.jsonToObject(DefaultPutRet.class);
        System.err.println(defaultPutRet.key);
        System.err.println(defaultPutRet.hash);
        // 访问路径
        String imgUrl = "p6yyzr1q1.bkt.clouddn.com" + "/" + defaultPutRet.key;
        System.err.println(imgUrl);
    } catch (QiniuException e) {
        e.printStackTrace();
    }
}
