如何使用angularjs将图片存到七牛云上

引入jar包：

<!-- 七牛云 -->
 <dependency>
      <groupId>com.qiniu</groupId>
      <artifactId>qiniu-java-sdk</artifactId>
      <version>7.2.11</version>
    </dependency>
    <dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>okhttp</artifactId>
      <version>3.3.1</version>
    </dependency>
    <dependency>
      <groupId>com.google.code.gson</groupId>
      <artifactId>gson</artifactId>
      <version>2.6.2</version>
    </dependency>
    <dependency>
      <groupId>com.qiniu</groupId>
      <artifactId>happy-dns-java</artifactId>
      <version>0.1.4</version>
    </dependency>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
    </dependency>

在页面上：xxx.html

2.在 xxxcontroller.js层

 然后写：

3.在uploadservice.js里面

到了 后端：专门写一个uplaodConctoller.java    就把图片的地址传到前端去了

这里面 用到了写的一个七牛云的工具类：

package com.youmeishenghuo.convertion;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

import org.springframework.web.multipart.MultipartFile;

import com.google.gson.Gson;
import com.qiniu.common.QiniuException;
import com.qiniu.common.Zone;
import com.qiniu.http.Response;
import com.qiniu.storage.Configuration;
import com.qiniu.storage.UploadManager;
import com.qiniu.storage.model.DefaultPutRet;
import com.qiniu.util.Auth;

public class PictureUtil {

	public static String accessKey = "这里改成自己七牛云的AS";
	public static String secretKey = "这里改成自己七牛云的S什么的密钥";
	public static String bucket = "这里写你在七牛云创建的空间名字";

	private static String QINIU_IMAGE_DOMAIN = "http://pgtzuyqwd.bkt.clouddn.com/";//这里也要改成你自己七牛云里的默认地址
            //传入本地文件地址
	public static String upload(String localFilePath) {
		// 构造一个带指定Zone对象的配置类
		Configuration cfg = new Configuration(Zone.zone1());// 这里是华北，对应1，华南，对应的2，你选择的是华什么就对应不同的数字
		UploadManager uploadManager = new UploadManager(cfg);
		// 默认不指定key的情况下，以文件内容的hash值作为文件名
		String key = null;

		Auth auth = Auth.create(accessKey, secretKey);
		String upToken = auth.uploadToken(bucket);

		DefaultPutRet putRet = null;

		try {
			Response response = uploadManager.put(localFilePath, key, upToken);
			// 解析上传成功的结果
			putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);
		} catch (QiniuException ex) {
			Response r = ex.response;
			System.err.println(r.toString());
			try {
				System.err.println(r.bodyString());
			} catch (QiniuException ex2) {
				// ignore
			}
		}
		return QINIU_IMAGE_DOMAIN + putRet.hash;
	}
          //传入一个流
	public static String upload(MultipartFile file) throws IOException {
		// 构造一个带指定Zone对象的配置类
		Configuration cfg = new Configuration(Zone.zone1());
		UploadManager uploadManager = new UploadManager(cfg);
		// 默认不指定key的情况下，以文件内容的hash值作为文件名
		String key = null;
		DefaultPutRet putRet = null;
		try {
			byte[] uploadBytes = file.getBytes();
			ByteArrayInputStream byteInputStream = new ByteArrayInputStream(uploadBytes);
			Auth auth = Auth.create(accessKey, secretKey);
			String upToken = auth.uploadToken(bucket);
			try {
				Response response = uploadManager.put(byteInputStream, key, upToken, null, null);
				putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);
			} catch (QiniuException ex) {
				Response r = ex.response;
				System.err.println(r.toString());
				try {
					System.err.println(r.bodyString());
				} catch (QiniuException ex2) {
					// ignore
				}
			}
		} catch (UnsupportedEncodingException ex) {
			// ignore
		}
		return QINIU_IMAGE_DOMAIN + putRet.hash;
	}
