spring boot整合FastDFS maven倉庫有jar包還是報錯怎麼辦？

阿新 • • 發佈：2022-05-05

一、首先，maven工程新增依賴

    <!--fastdfs-->
        <dependency>
            <groupId>org.csource</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27-RELEASE</version>
        </dependency>

如果報錯請參考maven倉庫有jar包還是報錯怎麼辦？

二、resources目錄下新增fdfs_client.conf檔案

前面使用nginx支援http方式訪問檔案，但所有人都能直接訪問這個檔案伺服器了，所以做一下許可權控制。

從來都是我能借用別人的圖片，而別人借用我的圖片不好意思不行！

FastDFS的許可權控制是在服務端開啟token驗證，客戶端根據檔名、當前unix時間戳、祕鑰獲取token，在地址中帶上token引數即可通過http方式訪問檔案。

#################### FastDFS-Client Start ####################
#預設值為30s
connect_timeout = 10
#預設值為30s
network_timeout = 30
charset = UTF-8
http.tracker_http_port = 80
# token 防盜鏈功能
http.anti_steal_token = true
http.secret_key = FastDFS1234567890
tracker_server = 192.168.1.118:22122
#tracker_server = 192.168.0.119:22122
## Tracker Server, if more than one, separate with ","
# fastdfs.tracker_servers=10.0.11.201:22122,10.0.11.202:22122,10.0.11.203:22122
#fastdfs.tracker_servers=${tracker_server_addr}:22122
#################### FastDFS-Client End ####################

對應檔案伺服器上/etc/fdfs下的http.conf

修改http.conf
# vim /etc/fdfs/http.conf

設定為true表示開啟token驗證
http.anti_steal.check_token=true

設定token失效的時間單位為秒(s)
http.anti_steal.token_ttl=1800

金鑰，跟客戶端配置檔案的fastdfs.http_secret_key保持一致
http.anti_steal.secret_key=FASTDFS1234567890

如果token檢查失敗，返回的頁面
http.anti_steal.token_check_fail=/ljzsg/fastdfs/page/403.html

記得重啟服務

三、客戶端生成token

訪問檔案需要帶上生成的token以及unix時間戳，所以返回的token是token和時間戳的拼接。

之後，將token拼接在地址後即可訪問：file.ljzsg.com/group1/M00/00/00/wKgzgFnkaXqAIfXyAAEoRmXZPp878.jpeg?token=078d370098b03e9020b82c829c205e1f&ts=1508141521

/**
     * 獲取訪問伺服器的token，拼接到地址後面
     *
     * @param filepath 檔案路徑 group1/M00/00/00/wKgzgFnkTPyAIAUGAAEoRmXZPp876.jpeg
     * @param httpSecretKey 金鑰
     * @return 返回token，如： token=078d370098b03e9020b82c829c205e1f&ts=1508141521
     */
    public static String getToken(String filepath, String httpSecretKey){
        // unix seconds
        int ts = (int) Instant.now().getEpochSecond();
        // token
        String token = "null";
        try {
            token = ProtoCommon.getToken(getFilename(filepath), ts, httpSecretKey);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (MyException e) {
            e.printStackTrace();
        }

        StringBuilder sb = new StringBuilder();
        sb.append("token=").append(token);
        sb.append("&ts=").append(ts);

        return sb.toString();
    }

注意事項

如果生成的token驗證無法通過，請進行如下兩項檢查：
　　A. 確認呼叫token生成函式(ProtoCommon.getToken)，傳遞的檔案ID中沒有包含group name。傳遞的檔案ID格式形如：M00/00/00/wKgzgFnkTPyAIAUGAAEoRmXZPp876.jpeg

　　B. 確認伺服器時間基本是一致的，注意伺服器時間不能相差太多，不要相差到分鐘級別。

對比下發現，如果系統檔案隱私性較高，可以直接通過fastdfs-client提供的API去訪問即可，不用再配置Nginx走http訪問。配置Nginx的主要目的是為了快速訪問伺服器的檔案(如圖片)，如果還要加許可權驗證，則需要客戶端生成token，其實已經沒有多大意義。關鍵是，這裡我沒找到FastDFS如何對部分資源加token驗證，部分開放。有知道的還請留言。

 */
public class FastDFSFile {

    private String name;//檔名

    private String ext; //副檔名，不包含（.）
    private String md5; //加密
    private String author;

    public FastDFSFile() {
    }

五、controller呼叫

@Controller
public class UploadController {
    private static Logger logger = LoggerFactory.getLogger(UploadController.class);

    @GetMapping("/")
    public String index() {
        return "upload";
    }
    

　　　　
    @PostMapping("/upload")
    public String singleFileUpload(@RequestParam("file") MultipartFile file,
                                   RedirectAttributes redirectAttributes) {
        if (file.isEmpty()) {
            redirectAttributes.addFlashAttribute("message", "Please select a file to upload");
            return "redirect:uploadStatus";
        }
        try {
            // Get the file and save it somewhere
            String path=saveFile(file);
            redirectAttributes.addFlashAttribute("message",
                    "You successfully uploaded '" + file.getOriginalFilename() + "'");
            redirectAttributes.addFlashAttribute("path",
                    "file path url '" + path + "'");
        } catch (Exception e) {
            logger.error("upload file failed",e);
        }
        return "redirect:/uploadStatus";
    }

    @GetMapping("/uploadStatus")
    public String uploadStatus() {
        return "uploadStatus";
    }

    /**
     * @param multipartFile
     * @return
     * @throws IOException 這個方法後面可以自己封裝一個util,這裡只是測試
     */
    public String saveFile(MultipartFile multipartFile) throws IOException {
        String[] fileAbsolutePath={};
        String fileName=multipartFile.getOriginalFilename();
        String ext = fileName.substring(fileName.lastIndexOf(".") + 1);
        byte[] file_buff = null;
        InputStream inputStream=multipartFile.getInputStream();
        if(inputStream!=null){
            int len1 = inputStream.available();
            file_buff = new byte[len1];
            inputStream.read(file_buff);
        }
        inputStream.close();
        FastDFSFile file = new FastDFSFile(fileName, file_buff, ext);
        try {
            fileAbsolutePath = FastDFSClient.upload(file);  //upload to fastdfs
        } catch (Exception e) {
            logger.error("upload file Exception!",e);
        }
        if (fileAbsolutePath==null) {
            logger.error("upload file failed,please upload again!");
        }
        String path=FastDFSClient.getTrackerUrl()+fileAbsolutePath[0]+ "/"+fileAbsolutePath[1];
        return path;
    }
}

一、首先，maven工程新增依賴

    <!--fastdfs-->

            <groupId>org.csource</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27-RELEASE</version>
        </dependency>

如果報錯請參考maven倉庫有jar包還是報錯怎麼辦？

二、resources目錄下新增fdfs_client.conf檔案

前面使用nginx支援http方式訪問檔案，但所有人都能直接訪問這個檔案伺服器了，所以做一下許可權控制。

從來都是我能借用別人的圖片，而別人借用我的圖片不好意思不行！

FastDFS的許可權控制是在服務端開啟token驗證，客戶端根據檔名、當前unix時間戳、祕鑰獲取token，在地址中帶上token引數即可通過http方式訪問檔案。

對應檔案伺服器上/etc/fdfs下的http.conf

修改http.conf
# vim /etc/fdfs/http.conf

設定為true表示開啟token驗證
http.anti_steal.check_token=true

設定token失效的時間單位為秒(s)
http.anti_steal.token_ttl=1800

金鑰，跟客戶端配置檔案的fastdfs.http_secret_key保持一致
http.anti_steal.secret_key=FASTDFS1234567890

如果token檢查失敗，返回的頁面
http.anti_steal.token_check_fail=/ljzsg/fastdfs/page/403.html

記得重啟服務

三、客戶端生成token

訪問檔案需要帶上生成的token以及unix時間戳，所以返回的token是token和時間戳的拼接。

之後，將token拼接在地址後即可訪問：file.ljzsg.com/group1/M00/00/00/wKgzgFnkaXqAIfXyAAEoRmXZPp878.jpeg?token=078d370098b03e9020b82c829c205e1f&ts=1508141521

     * @param httpSecretKey 金鑰
     * @return 返回token，如： token=078d370098b03e9020b82c829c205e1f&ts=1508141521
     */
    public static String getToken(String filepath, String httpSecretKey){
        // unix seconds
        int ts = (int) Instant.now().getEpochSecond();
        // token
        String token = "null";
        try {
            token = ProtoCommon.getToken(getFilename(filepath), ts, httpSecretKey);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (MyException e) {
            e.printStackTrace();
        }

        StringBuilder sb = new StringBuilder();
        sb.append("token=").append(token);
        sb.append("&ts=").append(ts);

        return sb.toString();
    }

注意事項

　　B. 確認伺服器時間基本是一致的，注意伺服器時間不能相差太多，不要相差到分鐘級別。

五、controller呼叫

@Controller
public class UploadController {
    private static Logger logger = LoggerFactory.getLogger(UploadController.class);

    @GetMapping("/")
    public String index() {
        return "upload";
    }
    

　　　　
    @PostMapping("/upload")
    public String singleFileUpload(@RequestParam("file") MultipartFile file,
                                   RedirectAttributes redirectAttributes) {
        if (file.isEmpty()) {
            redirectAttributes.addFlashAttribute("message", "Please select a file to upload");
            return "redirect:uploadStatus";
        }
        try {
            // Get the file and save it somewhere
            String path=saveFile(file);
            redirectAttributes.addFlashAttribute("message",
                    "You successfully uploaded '" + file.getOriginalFilename() + "'");
            redirectAttributes.addFlashAttribute("path",
                    "file path url '" + path + "'");
        } catch (Exception e) {
            logger.error("upload file failed",e);
        }
        return "redirect:/uploadStatus";
    }

    @GetMapping("/uploadStatus")
    public String uploadStatus() {
        return "uploadStatus";
    }

    /**
     * @param multipartFile

     */
    public String saveFile(MultipartFile multipartFile) throws IOException {
        String[] fileAbsolutePath={};
        String fileName=multipartFile.getOriginalFilename();
        String ext = fileName.substring(fileName.lastIndexOf(".") + 1);
        byte[] file_buff = null;
        InputStream inputStream=multipartFile.getInputStream();
        if(inputStream!=null){
            int len1 = inputStream.available();

        try {

        } catch (Exception e) {
            logger.error("upload file Exception!",e);
        }
        if (fileAbsolutePath==null) {
            logger.error("upload file failed,please upload again!");
        }
        String path=FastDFSClient.getTrackerUrl()+fileAbsolutePath[0]+ "/"+fileAbsolutePath[1];
        return path;
    }
}
