苏州保洁公司哪家比较好_html编辑器的功能介绍_网络推广有哪几种方法_站长工具排名分析

 前言：

因快手文档混乱，官方社区技术交流仍有很多未解之谜，下面3种文档的定义先区分。

代码中的JSON相关工具均用hutool工具包

1.快手 移动双端 原生SDK 文档https://mp.kuaishou.com/platformDocs/develop/mobile-app/ios.html

2.快手 Api 开放接口 文档https://mp.kuaishou.com/platformDocs/openAbility/contentManagement/createAVideo.html

3.快手 Java 服务端SDK maven 依赖 文档https://open.kuaishou.com/platform/openApi?menu=55

一、引入依赖

根据 3号 文档，虽然快手在JavaSDK中，封装了授权、用户信息、发布作品、直播等相关能力，但本次业务只涉及用户授权、发布视频，并且，SDK版的发布能力，不具备挂载小黄车的能力，所以只用到SDK中的授权能力。

            <dependency><groupId>com.github.kwaiopen</groupId><artifactId>kwai-open-sdk</artifactId><version>1.0.6</version></dependency>

二、信息配置

1.注册应用

快手有两个开放平台

①：快手开放平台——只涉及小程序

②：快手开放平台——5端统管

从 ② 进入创建开发者账户，并创建移动应用后提交审核。填写好ios和andriod信息，申请需要的权限

2.后端配置

yml中自定义参数

快手配置类

import com.github.kwai.open.api.KwaiOpenLiveApi;
import com.github.kwai.open.api.KwaiOpenOauthApi;
import com.github.kwai.open.api.KwaiOpenUserApi;
import com.github.kwai.open.api.KwaiOpenVideoApi;
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;/*** 快手配置类*/
@Data
@Component
public class KuaishouConfig {/*** App*/@Value("${kuaishou.appId}")private String appId;@Value("${kuaishou.appSecret}")private String appSecret;/*** 小程序*/@Value("${kuaishou.appletId}")private String appletId;@Value("${kuaishou.appletSecret}")private String appletSecret;//快手服务端SDK接入- java版本//https://open.kuaishou.com/platform/openApi?menu=55//快手开放Api//https://mp.kuaishou.com/platformDocs/openAbility/contentManagement/createAVideo.html//发起上传Apiprivate final String startUploadApi = "https://open.kuaishou.com/openapi/photo/start_upload";//上传视频Apiprivate final String uploadApi = "http://{endpoint}/api/upload";public String getUploadApi(String endpoint) {return uploadApi.replace("{endpoint}", endpoint);}//发布视频Apiprivate final String publishApi = "https://open.kuaishou.com/openapi/photo/publish";/*** oauth2.0协议的接口封装*/private KwaiOpenOauthApi kwaiOpenOauthApi;/*** 获取用户信息的相关接口封装*/private KwaiOpenUserApi kwaiOpenUserApi;/*** 发布内容能力的相关接口封装*/private KwaiOpenVideoApi kwaiOpenVideoApi;/*** 直播能力的相关接口封装*/private KwaiOpenLiveApi kwaiOpenLiveApi;/*** 初始化API接口实例，只执行一次，保证单例*/@PostConstructpublic void init() {this.kwaiOpenOauthApi = KwaiOpenOauthApi.init(appId);this.kwaiOpenUserApi = KwaiOpenUserApi.init(appId);this.kwaiOpenVideoApi = KwaiOpenVideoApi.init(appId);this.kwaiOpenLiveApi = KwaiOpenLiveApi.init(appId);}
}

三、实现

1.授权

前端部分跳转快手，指定scope权限，获取授权码自行实现

绑定第三方Controller

/*** 绑定第三方*/
@Validated
@RequiredArgsConstructor
@RestController
@RequestMapping("/api/bound")
public class BoundThirdPartController extends BaseController {private final ISysUserService userService;/*** 绑定快手* @param bound* @return*/@PostMapping("/kuaishou")public R<Void> boundKuaishou(@Validated @RequestBody KuaishouBound bound){SysUser user = userService.selectUserById(getUserId());if (StringUtils.isNotEmpty(user.getKuaishouOpenId())) {return R.fail("您已绑定过快手账号");}return toAjax(userService.boundKuaishou(bound, getUserId()));}
}

import lombok.Data;
import javax.validation.constraints.NotBlank;@Data
public class KuaishouBound {/*** 快手授权码*/@NotBlank(message = "快手授权码不能为空")private String kuaishouCode;
}

用户Service

@Slf4j
@RequiredArgsConstructor
@Service
public class SysUserServiceImpl implements ISysUserService{private final SysUserMapper baseMapper;private final IKuaishouService kuaishouService;@Overridepublic boolean boundKuaishou(KuaishouBound bound, Long userId) {AccessTokenResponse response = kuaishouService.getKuaishouAccessToken(bound.getKuaishouCode());String openId = response.getOpenId();String accessToken = response.getAccessToken();Long expiresIn = response.getExpiresIn();//查看此openid是否有被绑定过SysUser old = baseMapper.selectOne(Wrappers.<SysUser>lambdaQuery().eq(SysUser::getKuaishouOpenId, openId));if (ObjectUtil.isNotNull(old)) {//自己绑定过if (old.getUserId().equals(userId)) {throw new ServiceException("您已绑定该快手账户，请勿重复绑定！");}//别人绑定过throw new ServiceException("该快手已绑定到其他用户！");}RedisUtils.setCacheObject(CacheConstants.KUAISHOU_ACCESS_TOKEN + userId, accessToken, Duration.ofSeconds(expiresIn));//更新用户数据SysUser user = new SysUser();user.setUserId(userId);user.setKuaishouOpenId(openId);return baseMapper.updateById(user) > 0;}
}

快手Service

@Slf4j
@RequiredArgsConstructor
@Service
public class IKuaishouServiceImpl implements IKuaishouService {private final KuaishouConfig kuaishouConfig;/*** 获取快手AccessToken** @param kuaishouCode 授权码*/@Overridepublic AccessTokenResponse getKuaishouAccessToken(String kuaishouCode) {try {AccessTokenRequest tokenRequest = new AccessTokenRequest(kuaishouCode, kuaishouConfig.getAppSecret());return kuaishouConfig.getKwaiOpenOauthApi().getAccessToken(tokenRequest);} catch (KwaiOpenException e) {throw new RuntimeException(e);}}}

2.发布视频

文章开头说到的三种文档，都有各自的发布视频实现，这里选择第2种，Api的文档，因为只有Api接口中，可以带上小黄车的商品id。

但是！ 不要高兴的太早！

这里的商品id，只能是发布视频的账号下的橱窗自建商品。

附上我与快手社区官方的交流

接受了这点，就可以看接下来的代码了。或者你不需要挂载小黄车的功能，可以考虑更方便的3号文档中的实现方式

 业务Service

//快手创建一个视频需要执行 发起上传、上传视频、发布视频 三个步骤
//1.发起上传
JSONObject startResult = kuaishouService.startUpload(userId);
//2.上传视频
String endpoint = startResult.get("endpoint", String.class);
String uploadToken = startResult.get("upload_token", String.class);
Boolean uploadResult = kuaishouService.uploadMp4(endpoint,uploadToken,"mp4短视频 http url 地址");
//3.发布视频
JSONObject publishResult = kuaishouService.publishVideo(userId, "封面图 http url 地址", uploadToken, "短视频标题 （示例#话题）", "NOT_SPHERICAL_VIDEO", "快手账户 快手小店 中 商品id");
// 4.得到的publishResult 结果，进行业务处理

为了弄清混乱的快手开发，和根本没有官方技术回答，整理不易。
