InputStream输入流七牛上传图片
流程导入七牛Maven jar包直接调用配置类以及上传类，获取返回文件名字demo流程
导入七牛Maven jar包
<dependency><groupId>com.qiniu</groupId><artifactId>qiniu-java-sdk</artifactId><version>7.2.11</version><scope>compile</scope></dependency><dependency><groupId>com.qiniu</groupId><artifactId>happy-dns-java</artifactId><version>0.1.4</version><scope>compile</scope></dependency>
直接调用配置类以及上传类，获取返回文件名字
配置类
public class QIniu {//七牛相关配置信息（本人是通过读取yaml配置文件读取七牛配置参数）public static final String QINIU_DOMAIN=AllConfig.getAllConfig().get("QINIU_DOMAIN_IMAGE").toString();public static final String QINIU_BASE_URL = AllConfig.getAllConfig().get("QINIU_BASE_URL_IMAGE").toString();public static final String QINIU_AK = AllConfig.getAllConfig().get("QINIU_AK").toString();public static final String QINIU_SK = AllConfig.getAllConfig().get("QINIU_SK").toString();}
上传类
/*** 图片访问的外链* @author Jian**/public class QiniuUpload {public String uploadImgImputStream(InputStream itm,String key) {Configuration cfg = new Configuration(Zone.zone2());//...其他参数参考类注释UploadManager uploadManager = new UploadManager(cfg);String upToken=getUpTokens();try {Response response = uploadManager.put(itm,key,upToken,null, null);//解析上传成功的结果DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);return putRet.key;} catch (QiniuException ex) {Response r = ex.response;System.out.println(r.toString());try {System.out.println(r.bodyString());} catch (QiniuException ex2) {//ignore}}return null;}/*** 获取签名* @author Jian**/public String getUpTokens() {Auth auth = Auth.create(QIniu.QINIU_AK, QIniu.QINIU_SK);return auth.uploadToken(QIniu.QINIU_DOMAIN);}
demo
/*** 路径：拼接QINIU_BASE_URL* QIniu.QINIU_BASE_URL+返回名字* JsonResult只是本人自定义的数据类* @author Jian**/public JsonResult<Void> upload(HttpServletRequest request,HttpServletResponse response,@RequestParam("file") MultipartFile file) throws IOException {//转换成流InputStream is = file.getInputStream();JsonResult<Void>jr=new JsonResult<Void>();String fileName = String.valueOf(System.currentTimeMillis());QiniuUpload qiniu = new QiniuUpload();//调用上传类上传String f= qiniu.uploadImgImputStream(is,fileName);if(!f.isEmpty()) {jr.setData(QIniu.QINIU_BASE_URL+f);jr.setState(1);}return jr;}
