access servle 設置 string gets ont 圖片上傳 擴展名 summary 
做後臺的時候，寫了兩個方法，分別用來獲取安卓和蘋果IOS端上傳的頭像，保存到阿裏雲OSS圖片存儲服務器上。（SMM框架）
安卓及H5版本：
1 /** 2 * 上傳用戶頭像 3 */ 4 @RequestMapping("/uploadPhoto") 5 public R uploadPhoto(@RequestParam("imgFile") MultipartFile imgFile, HttpServletRequest req) throws Exception { 6 if (imgFile.isEmpty()) { 7View Codethrow new RRException("上傳文件不能為空"); 8 } 9 10 Integer uid = WebUtils.getUid(req); 11 WfMemberEntity member = memberService.queryObject(uid); 12 13 String newsUrl = ""; 14 if (!((MultipartFile) imgFile).isEmpty()) { 15 try{ 16 newsUrl = OSSUtil.addFile(imgFile, "head", Constants.IGM_BUCKET); 17 18 } catch (IOException e) { 19 e.printStackTrace(); 20 } 21 }else { 22 return R.error("上傳圖片不可為空"); 23 } 24 if(member.getHeadimage() == null) { 25 member.setHeadimage(newsUrl); 26 member.setThumbimg(newsUrl); 27 memberService.update(member); 28 }else { 29 // 刪除原來圖片 30 OSSUtil.delete(member.getHeadimage(), Constants.IGM_BUCKET); 31 member.setHeadimage(newsUrl); 32 member.setThumbimg(newsUrl); 33 memberService.update(member); 34 } 35 System.out.println("*************************************頭像路徑： "+newsUrl+"***************************************"); 36 return R.ok().put("url", newsUrl); 37 }
對應的蘋果圖片上傳版本：
1 @RequestMapping("/iosUpload") 2 public R iosUpload(HttpServletRequest req){ 3 4 Integer uid = WebUtils.getUid(req); 5 WfMemberEntity member = memberService.queryObject(uid); 6 7 String image = req.getParameter("image"); 8 // 將base64 轉 字節數組 9 Base64 base = new Base64(); 10 byte[] decode = base.decode(image); 11 12 // 定義圖片輸入流 13 InputStream fin = new ByteArrayInputStream(decode); 14 15 String newsUrl = ""; 16 try { 17 newsUrl = OSSUtil.putFile(fin, "head", Constants.IGM_BUCKET); 18 } catch (IOException e) { 19 e.printStackTrace(); 20 } 21 if(member.getHeadimage() == null) { 22 member.setHeadimage(newsUrl); 23 member.setThumbimg(newsUrl); 24 memberService.update(member); 25 }else { 26 // 刪除原來圖片 27 OSSUtil.delete(member.getHeadimage(), Constants.IGM_BUCKET); 28 member.setHeadimage(newsUrl); 29 member.setThumbimg(newsUrl); 30 memberService.update(member); 31 } 32 System.out.println("*************************************頭像路徑： "+newsUrl+"***************************************"); 33 return R.ok().put("url", newsUrl); 34 }View Code
