Java实现七牛云上传图片、读取图片链接
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
Java后端實現七牛云上傳圖片、讀取圖片鏈接
添加依賴
<!--七牛云sdk--><dependency><groupId>com.qiniu</groupId><artifactId>qiniu-java-sdk</artifactId><version>7.2.11</version></dependency>controller
@Api("文件上傳") @RestController public class UploadController {@Autowiredprivate UploadService uploadService;@PostMapping(path = "/avatar",produces = "application/json")@ApiOperation("更換頭像")public ResModel replaceAvator(@ApiParam("頭像文件") MultipartFile file) throws IOException {return uploadService.replaceAvatar(file);} }service接口
public interface UploadService {ResModel replaceAvatar(MultipartFile file); }serivce實現類
@Service public class UploadServiceImpl implements UploadService {//上傳文件@Overridepublic ResModel replaceAvatar(MultipartFile file) {try {/** 華北是zone1, [華東z0] [華南z2] [北美na0] [東南亞as0] */Configuration config = new Configuration(Zone.zone0());UploadManager manager = new UploadManager(config);String accessKey="XXX";String secretKey="XXX";String bucket="XXX";Auth auth = Auth.create(accessKey, secretKey);String token = auth.uploadToken(bucket);Response response = manager.put(file.getInputStream(), file.getOriginalFilename(), token, null, null);//解析上傳成功的結果DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);System.out.println(putRet.key);//文件名稱System.out.println(putRet.hash);//空間hash值//根據文件名獲取七牛云存儲鏈接String path = getFilePath(putRet.key);System.out.println(path);return path;} catch (IOException e) {throw new RuntimeException(e);}}//讀取文件public static String getFilePath(String fileName) {//自己的域名路徑+文件名String publicUrl = "XXX"+ fileName;/*** 空間為私有訪問，需要驗證 tokenString accessKey="XXX";String secretKey="XXX";Auth auth = Auth.create(accessKey, secretKey);long expireInSeconds = 3600; //1小時，可以自定義鏈接過期時間String finalUrl = auth.privateDownloadUrl(publicUrl, expireInSeconds);*/return publicUrl;} }前端
