Java开发实践：利用七牛云实现图片上传功能

import com.qiniu.storage.Configuration;
import com.qiniu.storage.UploadManager;
import com.qiniu.util.Auth;

public class ImageUploader {
    // 七牛云存储的配置信息
    private static final String ACCESS_KEY = "your-access-key";
    private static final String SECRET_KEY = "your-secret-key";
    private static final String BUCKET_NAME = "your-bucket-name";

    public static void uploadImage(String localFilePath) {
        // 创建七牛云存储的配置对象
        Configuration configuration = new Configuration();

        // 创建七牛云存储的认证对象
        Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);
        
        // 获取上传凭证
        String uploadToken = auth.uploadToken(BUCKET_NAME);

        // 创建七牛云存储的上传管理器
        UploadManager uploadManager = new UploadManager(configuration);

        try {
            // 调用上传方法将本地文件上传到七牛云
            Response response = uploadManager.put(localFilePath, null, uploadToken);
            
            // 获取上传结果
            DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);
            
            // 打印上传结果中的图片链接
            System.out.println("Image URL: " + "http://" + BUCKET_NAME + ".qiniudn.com/" + putRet.key);
        } catch (QiniuException e) {
            e.printStackTrace();
        }
    }
