java上传文件到七牛云中

一、加载七牛云SDK

		
		  com.qiniu
		  qiniu-java-sdk
		  [7.2.0, 7.2.99]
        

二、java代码

package com.lei.utils;  
  
import com.qiniu.util.Auth;  
import java.io.IOException;  
import com.qiniu.common.QiniuException;  
import com.qiniu.http.Response;
import com.qiniu.storage.Configuration;
import com.qiniu.storage.UploadManager;  
  
public class QiNiuFileUpUtil {  
      
    /**基本配置-从七牛管理后台拿到*/  
  //设置好账号的ACCESS_KEY和SECRET_KEY  
  String ACCESS_KEY = "AK";  
  String SECRET_KEY = "SK";  
  //要上传的空间名--  
  String bucketname = "空间名";  
    
    
    
  /**指定保存到七牛的文件名--同名上传会报错  {"error":"file exists"}*/  
  /** {"hash":"FrQF5eX_kNsNKwgGNeJ4TbBA0Xzr","key":"aa1.jpg"} 正常返回 key为七牛空间地址 http:/xxxx.com/aa1.jpg */  
  //上传文件的路径  
  String FilePath ="D:\\1.png";  
//上传到七牛后保存的文件名    访问为：http://oswj11a86.bkt.clouddn.com/daimo6.png
  String key = "daimo6.png";    
  
  //密钥配置  
  Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);  
  //创建上传对象  
  UploadManager uploadManager =new UploadManager(new Configuration()); 
    
  
  //简单上传，使用默认策略，只需要设置上传的空间名就可以了  
  public String getUpToken(){  
      return auth.uploadToken(bucketname);  
  }  
  
  public void upload() throws IOException{  
    try {  
      //调用put方法上传  
          
      Response res = uploadManager.put(FilePath, key, getUpToken());  
      //打印返回的信息  
      System.out.println(res.bodyString());  
      System.out.println(res.statusCode);//200为上传成功
      } catch (QiniuException e) {  
          Response r = e.response;  
          // 请求失败时打印的异常的信息  
          System.out.println(r.toString());  
          try {  
              //响应的文本信息  
            System.out.println(r.bodyString());  
          } catch (QiniuException e1) {  
              //ignore  
          }  
      }         
  }  
  
  public static void main(String args[]) throws IOException{    
    new QiNiuFileUpUtil().upload();  
  }  
  
}
