2.在 xxxcontroller.js層
然後寫:
3.在uploadservice.js裡面
到了 後端:專門寫一個uplaodConctoller.java 就把圖片的地址傳到前端去了
這裡面 用到了寫的一個七牛雲的工具類:
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 = "這裡改成自己七牛雲的AS"; public static String secretKey = "這裡改成自己七牛雲的S什麼的金鑰"; public static String bucket = "這裡寫你在七牛雲建立的空間名字"; private static String QINIU_IMAGE_DOMAIN = "http://pgtzuyqwd.bkt.clouddn.com/";//這裡也要改成你自己七牛雲裡的預設地址 //傳入本地檔案地址 public static String upload(String localFilePath) { // 構造一個帶指定Zone物件的配置類 Configuration cfg = new Configuration(Zone.zone1());// 這裡是華北,對應1,華南,對應的2,你選擇的是華什麼就對應不同的數字 UploadManager uploadManager = new UploadManager(cfg); // 預設不指定key的情況下,以檔案內容的hash值作為檔名 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); // 解析上傳成功的結果 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; } //傳入一個流 public static String upload(MultipartFile file) throws IOException { // 構造一個帶指定Zone物件的配置類 Configuration cfg = new Configuration(Zone.zone1()); UploadManager uploadManager = new UploadManager(cfg); // 預設不指定key的情況下,以檔案內容的hash值作為檔名 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; } }
