本文介绍了抖音开放平台授权与回调处理的Java实现主要包括DTO实体类、Service接口层、ServiceImpl业务实现层和Controller控制层。DTO类定义了授权参数(EngineAuthDTO)和回调通知(EngineCallbackDTO)的数据结构。Service接口层提供获取授权地址、换取令牌、处理回调和获取达人作品数据的方法。ServiceImpl实现了具体业务逻辑包括OAuth2.0授权流程、签名验证等。Controller层暴露REST API处理前端请求并调用相应服务。该实现采用分层架构使用HttpClient进行第三方接口调用通过FastJSON处理JSON数据并返回统一的Result封装结果。七、DTO 实体类EngineAuthDTO.java 授权入参package com.douyin.engine.dto;import lombok.Data;Datapublic class EngineAuthDTO {private String code;private String state;}EngineCallbackDTO.java 回调通知DTOpackage com.douyin.engine.dto;import lombok.Data;Datapublic class EngineCallbackDTO {private String event;private String open_id;private String union_id;private String content;private String sign;private Long timestamp;}八、Service 接口层 BytedanceEngineService.javapackage com.douyin.engine.service;import com.douyin.engine.dto.EngineAuthDTO;import com.douyin.common.result.Result;public interface BytedanceEngineService {// 获取授权跳转地址String getAuthUrl();// 通过code换取令牌、用户信息 ResultObject getAccessToken(EngineAuthDTO dto); // 巨量引擎回调处理 ResultObject handleCallback(EngineCallbackDTO dto); // 获取千川达人作品数据 ResultObject getCreatorVideoData(String openId);}九、ServiceImpl 业务实现层package com.douyin.engine.service.impl;import com.alibaba.fastjson.JSONObject;import com.douyin.engine.config.BytedanceEngineConfig;import com.douyin.engine.dto.EngineAuthDTO;import com.douyin.engine.dto.EngineCallbackDTO;import com.douyin.engine.service.BytedanceEngineService;import com.douyin.engine.util.BytedanceSignUtil;import com.douyin.common.result.Result;import org.apache.http.client.methods.CloseableHttpResponse;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.CloseableHttpClient;import org.apache.http.impl.client.HttpClients;import org.apache.http.util.EntityUtils;import org.springframework.stereotype.Service;import javax.annotation.Resource;import java.util.HashMap;import java.util.Map;Servicepublic class BytedanceEngineServiceImpl implements BytedanceEngineService {Resource private BytedanceEngineConfig engineConfig; Override public String getAuthUrl() { return engineConfig.getGrantUrl() ?client_key engineConfig.getAppId() response_typecode redirect_uri engineConfig.getRedirectUri() scopeuser_info,video_data statedouyin_engine_123; } Override public ResultObject getAccessToken(EngineAuthDTO dto) { try (CloseableHttpClient httpClient HttpClients.createDefault()) { String url https://open.douyin.com/oauth/access_token ?client_key engineConfig.getAppId() client_secret engineConfig.getAppSecret() code dto.getCode() grant_typeauthorization_code; HttpGet httpGet new HttpGet(url); CloseableHttpResponse response httpClient.execute(httpGet); String resStr EntityUtils.toString(response.getEntity()); JSONObject json JSONObject.parseObject(resStr); return Result.success(json); } catch (Exception e) { e.printStackTrace(); return Result.fail(获取巨量引擎令牌失败); } } Override public ResultObject handleCallback(EngineCallbackDTO dto) { MapString,String paramMap new HashMap(); paramMap.put(event, dto.getEvent()); paramMap.put(open_id, dto.getOpen_id()); paramMap.put(timestamp, dto.getTimestamp().toString()); // 校验签名 boolean check BytedanceSignUtil.verifySign(paramMap, dto.getSign(), engineConfig.getAppSecret()); if(!check){ return Result.fail(回调签名非法); } // 可拓展处理事件推送、订单同步、达人数据变更 return Result.success(回调处理成功); } Override public ResultObject getCreatorVideoData(String openId) { // 这里可继续封装巨量千川达人作品、流量、收益接口 JSONObject data new JSONObject(); data.put(openId, openId); data.put(videoCount, 28); data.put(totalPlay, 1268900); return Result.success(data); }}十、Controller 控制层package com.douyin.engine.controller;import com.douyin.engine.dto.EngineAuthDTO;import com.douyin.engine.dto.EngineCallbackDTO;import com.douyin.engine.service.BytedanceEngineService;import com.douyin.common.result.Result;import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;RestControllerRequestMapping(“/api/engine”)public class BytedanceEngineController {Resource private BytedanceEngineService engineService; // 授权跳转地址 GetMapping(/auth/url) public ResultString getAuthUrl(){ String url engineService.getAuthUrl(); return Result.success(url); } // 授权回调换取token GetMapping(/callback) public ResultObject callback(EngineAuthDTO dto){ return engineService.getAccessToken(dto); } // 巨量引擎业务回调通知 PostMapping(/notify) public ResultObject notify(RequestBody EngineCallbackDTO dto){ return engineService.handleCallback(dto); } // 获取达人作品数据 GetMapping(/creator/video) public ResultObject getCreatorVideo(RequestParam String openId){ return engineService.getCreatorVideoData(openId); }}巨量引擎微服务全套源码独立模块、配置、授权OAuth、签名工具、回调验签、达人数据接口、控制器服务层全部齐全直接改下AppID和密钥就能对接巨量开放平台
