這里主要講 java后臺

我這里用的是七牛云

Controller層

package com.xianbaovip.project.Controller; import cn.hutool.core.lang.ObjectId; import cn.hutool.json.JSONObject; import cn.hutool.json.JSONUtil; import com.xianbaovip.project.Modle.dto.ImgResultDto; import com.xianbaovip.project.Server.UploadImg.UploadImgService; import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.multipart.MultipartFile;@RestController public class UploadImgCrotroller {@Autowiredprivate UploadImgService uploadImgService;@RequestMapping("/uploadImg")public String updata(@RequestParam(name="file") MultipartFile file) throws Exception {//首先判斷是不是空的文件if (!file.isEmpty()) { // //對文文件的全名進行截取然后在后綴名進行刪選。 // int begin = file.getOriginalFilename().indexOf("."); // int last = file.getOriginalFilename().length(); // String suffix = file.getOriginalFilename().substring(begin, last); // // //讀取文件的后綴名字 // String fileName = imgId+suffix;//生成圖片的唯一idString imgId = ObjectId.next();ImgResultDto imgResultDto = uploadImgService.uploadImage(imgId, file);String jsonStr= JSONUtil.toJsonStr(imgResultDto);return jsonStr;}else{JSONObject json1 = JSONUtil.createObj();json1.put("code", 300);json1.put("msg", "圖片上傳錯誤");String jsonStr= JSONUtil.toJsonStr(json1);return jsonStr;}} }

Server層

package com.xianbaovip.project.Server.UploadImg;import cn.hutool.core.util.StrUtil; import com.xianbaovip.project.Common.constant; import com.xianbaovip.project.Modle.dto.ImgResultDto; import com.xianbaovip.project.Utils.UpdataImgUtils;import org.apache.catalina.User; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Service; import org.springframework.web.multipart.MultipartFile;import java.io.IOException; import java.util.ArrayList; import java.util.List;@Service @PropertySource("classpath:common.properties") public class UploadImgService {@Value("${imgServer}")private String imgServer;public ImgResultDto uploadImage(String imgId,MultipartFile file) throws IOException {String putRetKey = new UpdataImgUtils().UpdataImg(imgId, file.getBytes());String[] urlData = new String[1];ImgResultDto imgResultDto = new ImgResultDto();if(!StrUtil.hasBlank(putRetKey)){//設置返回值的類urlData[0] =imgServer+imgId;imgResultDto.setErrno(constant.imgErrorStart);//設置狀態碼imgResultDto.setData(urlData);}else{imgResultDto.setErrno(constant.imgErrorStart1);//設置狀態碼}return imgResultDto;} }

工具類

package com.xianbaovip.project.Utils;import com.google.gson.Gson; import com.qiniu.common.QiniuException; import com.qiniu.http.Response; import com.qiniu.storage.Configuration; import com.qiniu.storage.Region; import com.qiniu.storage.UploadManager; import com.qiniu.storage.model.DefaultPutRet; import com.qiniu.util.Auth; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.PropertySource;import java.io.ByteArrayInputStream; import java.io.UnsupportedEncodingException;public class UpdataImgUtils {private static final String img_Ak = "自行填寫";private static final String img_Sk = "自行填寫";private static final String img_Bucket = "自行填寫";private static final String img_Url = "自行填寫";public String UpdataImg(String imgName, byte[] uploadBytes ){String putRetKey = "";//構造一個帶指定Region對象的配置類Configuration cfg = new Configuration(Region.region1());//...其他參數參考類注釋UploadManager uploadManager = new UploadManager(cfg);//...生成上傳憑證，然后準備上傳String accessKey = img_Ak;String secretKey = img_Sk;String bucket = img_Bucket;//如果是Windows情況下，格式是 E:\ss.jpg//String localFilePath = "E:\\ss.jpg";//默認不指定key的情況下，以文件內容的hash值作為文件名//String key = null;//byte[] uploadBytes = "hello qiniu cloud".getBytes("utf-8");ByteArrayInputStream byteInputStream=new ByteArrayInputStream(uploadBytes);Auth auth = Auth.create(accessKey, secretKey);String upToken = auth.uploadToken(bucket,imgName);try {Response response = uploadManager.put(byteInputStream,imgName,upToken,null, null);//解析上傳成功的結果DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);putRetKey = putRet.key;System.out.println(putRet);System.out.println(putRet.key);System.out.println(putRet.hash);} catch (QiniuException ex) {Response r = ex.response;System.err.println(r.toString());try {System.err.println(r.bodyString());} catch (QiniuException ex2) {//ignore}}return putRetKey;} }
