FastDFS开启token防盗链

  在实际的项目开发中，是不是迂到这样的问题，输入一个完的地址后，就显示出了相对应的图片。为了预防这类问题，所以使用到fdfs的token; 

 开启token后，在访问这个地址

一、修改fdfs的http.conf配置文件 

   cd /etc/fdfs/

   vi http.conf

## 开启token

# 服务器配置的秘钥

 http.anti_steal.secret_key=Fdfs@0903&!

二、pom.xml

<dependency>
   <groupId>net.oschina.zcx7878</groupId>
   <artifactId>fastdfs-client-java</artifactId>
   <version>1.27.0.0</version>
</dependency>

三、工具类

import org.csource.common.MyException;
import org.csource.fastdfs.ProtoCommon;

import java.io.UnsupportedEncodingException;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.NoSuchAlgorithmException;
import java.time.Instant;

public class FastDfsUtils {
    /**
     * 获取访问服务器的token，拼接到地址后面
     *
     * @param filepath      文件路径 group1/M00/00/00/wKgzgFnkTPyAIAUGAAEoRmXZPp876.jpeg
     * @param httpSecretKey 密钥
     * @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 {
            String path = getPath(filepath);
            if(StringUtils.isEmpty(path)){
                return null;
            }
            token = ProtoCommon.getToken(path, 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();
    }

    public static String getPath(String filepath){
        //截取下标
        String sub = "/group1/";
        int index = filepath.indexOf(sub);
        if(index <= 0){
            //地址为空,或地址不包含"/group1/"路径
            return null;
        }
        // 截取字符串
        String path = filepath.substring(index + sub.length());
//        System.out.println(result); // 输出如：M00/00/0A/wKhDKWDnqD2Aa-qCAAFdD_Pw4vA622.jpg
        return path;
    }

    public static String getUrlWithToken(String filepath, String httpSecretKey){
        String token = getToken(filepath, httpSecretKey);
        if(StringUtils.isEmpty(token)){
            return null;
        }
        return filepath + "?" + token;
    }

    public static String getUrlWithoutToken(String urlWithToken){
        //截取下标
        String sub = "?token=";
        int index = urlWithToken.indexOf(sub);
        if(index <= 0){
            return urlWithToken;
        }
        // 截取字符串
        String path = urlWithToken.substring(0, index);
//        System.out.println(path); 
        return path;
    }

    public static void main(String[] args) {
        String url = "https://xxxxxx/group1/M00/00/0B/wKhDKWE1xpuAHx-hAAy2WlTKUp8445.jpg";
        getUrlWithoutToken(url);
        System.out.println(getUrlWithToken(url,"Fdfs@0903&!"));
    }
}

四、业务层代码

@GetMapping("/info/{id}")
@ApiOperation(value = "根据作品id获取个人作品详细信息", notes = "根据作品id获取个人作品详细信息")

@ApiImplicitParam(name = "id", value = "作品id", required = true, dataType = "Long")
public Result<Object> entInfo(@PathVariable(value = "id") Long id) throws MalformedURLException {

 //根据Id到个人作品的具体信息，个人作品信息中有一个字段放到的是 https://xxxx/group1/M00/00/0B/wKhDKWE1xpuAHx-hAAy2WlTKUp8445.jpg,假如这个字段是url
personInfo  info= person.getPersonInfoDetail(id);

info.setUrl(FastDfsUtils.getUrlWithToken(detail.getIdUrl,fdfsSecretKey));

System.out.print(info.setUrl()); 
//https://XXXX/group1/M00/00/0B/wKhDKWE1xpuAHx-hAAy2WlTKUp8445.jpg?token=cb2d9ee1a639b2e8f1f9776a3494b1ce&ts=1693723731

return Result.success(info);

}
五、校验
