根據(jù)現(xiàn)有的平臺小程序，快速發(fā)布一個(gè)相同類型的小程序

如果按常規(guī)的做法每個(gè)小程序都需要經(jīng)歷這樣的步驟：在公眾平臺申請appid——>拉代碼到自己的倉庫——>打開編譯器綁定自己的appId——>上傳代碼到公眾平臺——>再提交審核——>在公眾平臺調(diào)整開發(fā)設(shè)置。

如果用微信開放平臺的服務(wù)平臺開發(fā)的步驟：在微信開放平臺申請第三方服務(wù)平臺——>上傳小程序模板（只有第一次有）——>調(diào)接口上傳小程序代碼

——>調(diào)接口提交審核——>調(diào)接口發(fā)布小程序。

上傳小程序模板的步驟：在公眾平臺申請appid——>在微信開放平臺的第三方服務(wù)平臺中添加開發(fā)小程序——>上傳小程序代碼（此時(shí)會直接上傳到了開放平臺的草稿箱）——>將草稿箱的代碼作為普通模板

這就是服務(wù)平臺開發(fā)平臺的便捷，只需上傳一次小程序代碼，就可以快速的發(fā)布小程序。

實(shí)現(xiàn)

步驟：獲取component_verify_ticket——>獲取component_access_token——>獲取authorizer_access_token——>調(diào)接口發(fā)布小程序

1、獲取component_verify_ticket

官方文檔：驗(yàn)證票據(jù) | 微信開放文檔 (qq.com)

因?yàn)檫@個(gè)驗(yàn)證票據(jù)是微信官方主動推送的，所以需要在第三方平臺配置一波

controller

@ApiOperation(value = "微信開放平臺：授權(quán)事件接收URL,驗(yàn)證票據(jù)", notes = "zhuguangliang") @AnonymousPostMapping("/pushTicket") public String wechatPlatformEvent(@RequestParam("timestamp") String timestamp,@RequestParam("nonce") String nonce,@RequestParam("msg_signature") String msgSignature,@RequestBody String postData) {return openPlatformUtil.parseRequest(timestamp, nonce, msgSignature, postData); }

實(shí)現(xiàn)類

關(guān)于存儲component_verify_ticket方案，我這里是mysql和redis各存一份。

public String parseRequest(String timeStamp, String nonce, String msgSignature, String postData) {try {if (redisUtils.hasKey(CacheKey.OPEN_PLATFORM_TICKET)) {return "success";}//這個(gè)類是微信官網(wǎng)提供的解密類,需要用到消息校驗(yàn)Token 消息加密Key和服務(wù)平臺appidWXBizMsgCrypt pc = new WXBizMsgCrypt(Token, Key, APPID);String xml = pc.decryptMsg(msgSignature, timeStamp, nonce, postData);Map<String, String> result = WXXmlToMapUtil.xmlToMap(xml);// 將xml轉(zhuǎn)為mapString componentVerifyTicket = result.get("ComponentVerifyTicket");if (StringUtils.isNotEmpty(componentVerifyTicket)) {// 存儲平臺授權(quán)票據(jù),保存ticketSpiritOpenPlatform spiritOpenPlatform = new SpiritOpenPlatform();if (platformMapper.selectByAppId(APPID) == 0) {spiritOpenPlatform.setAppid(APPID);spiritOpenPlatform.setAppSecret(AppSecret);spiritOpenPlatform.setPlatformKey(Key);spiritOpenPlatform.setToken(Token);spiritOpenPlatform.setComponentVerifyTicket(componentVerifyTicket);platformMapper.insert(spiritOpenPlatform);} else {spiritOpenPlatform.setComponentVerifyTicket(componentVerifyTicket);LambdaUpdateWrapper<SpiritOpenPlatform> updateWrapper = new LambdaUpdateWrapper<>();updateWrapper.eq(SpiritOpenPlatform::getAppid, APPID);platformMapper.update(spiritOpenPlatform, updateWrapper);}redisUtils.set(CacheKey.OPEN_PLATFORM_TICKET, componentVerifyTicket, 60 * 60 * 12);log.info("微信開放平臺，第三方平臺獲取【驗(yàn)證票據(jù)】成功");} else {log.error("微信開放平臺，第三方平臺獲取【驗(yàn)證票據(jù)】失敗");}} catch (AesException e) {log.error("微信開放平臺，第三方平臺獲取【驗(yàn)證票據(jù)】失敗,異常信息：" + e.getMessage());}return "success";}

2、獲取component_access_token

官方文檔：令牌 | 微信開放文檔 (qq.com)

實(shí)現(xiàn)類

3、獲取authorizer_access_token

步驟：

獲取預(yù)授權(quán)碼pre_auth_code——>微信公眾平臺管理員授權(quán)——>獲取authorizer_access_token&authorizer_refresh_token

官方文檔：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/Before_Develop/Authorization_Process_Technical_Description.html

①獲取預(yù)授權(quán)碼pre_auth_code

@Override public String getPreAuthCode() {//先判斷component_access_token是否過期，如果過期重新獲取getComponentAccessToken();String preAuthCodeUrl = "https://api.weixin.qq.com/cgi-bin/component/api_create_preauthcode?component_access_token=" + redisUtils.get(CacheKey.COMPONENT_ACCESS_TOKEN);JSONObject params = new JSONObject();params.put("component_appid", APPID);JSONObject data = JSONObject.parseObject(HttpUtil.post(preAuthCodeUrl, JSON.toJSONString(params)));if (data.containsKey("pre_auth_code")) {return data.getString("pre_auth_code");}throw new BadRequestException("獲取預(yù)授權(quán)失敗,接口返回信息：" + data.toJSONString()); }

②微信公眾平臺管理員授權(quán)

生成授權(quán)鏈接，可以在前端用a標(biāo)簽填入這個(gè)接口地址，點(diǎn)擊a標(biāo)簽打開新標(biāo)簽頁，管理員進(jìn)行掃碼授權(quán)

@Override public void toAuthorization(HttpServletResponse response) throws IOException {String authUrl = "https://mp.weixin.qq.com/cgi-bin/componentloginpagecomponent_appid=%s&pre_auth_code=%s&redirect_uri=%s&auth_type=1";String redirectUrl = "https://服務(wù)端地址/callback";String preAuthCode = getPreAuthCode();response.setStatus(301);response.sendRedirect(String.format(authUrl, APPID, preAuthCode, redirectUrl)); }

授權(quán)之后，會回調(diào)：“https://服務(wù)端地址/callback”，并將授權(quán)碼auth_code攜帶到這個(gè)接口

@ApiOperation(value = "微信開放平臺：用戶授權(quán)后，回調(diào)地址", notes = "zhuguangliang")@AnonymousGetMapping("/callback")@Notice("2393194918@qq.com")public void callback(String auth_code) { // openPlatformService.getAuthorizationInfo(auth_code);}

③獲取authorizer_access_token&authorizer_refresh_token

官方文檔：https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/ThirdParty/token/authorization_info.html

說明：authorization_code就是授權(quán)之后，返回的授權(quán)碼

如果你使用微信的第三方平臺管理工具，可以在數(shù)據(jù)庫中直接獲取authorizer_refresh_token，然后根據(jù)：

獲取/刷新接口調(diào)用令牌 | 微信開放文檔 (qq.com)這個(gè)接口進(jìn)行刷新authorizer_access_token，下面是實(shí)現(xiàn)代碼：

@Override//authorizerAppId為授權(quán)的appid public void getAuthorizationInfo(String authorizerAppId) {String key = CacheKey.AUTH_ACCESS_TOKEN + authorizerAppId;//這一步是為如果發(fā)現(xiàn)這個(gè)token快過期，則刷新if (redisUtils.hasKey(key) && redisUtils.getExpire(key) > 5 * 60) {return;}getComponentAccessToken();String refreshTokenUrl = "https://api.weixin.qq.com/cgi-bin/component/api_authorizer_token?component_access_token=" + redisUtils.get(CacheKey.COMPONENT_ACCESS_TOKEN);JSONObject param = new JSONObject();param.put("component_appid", APPID);param.put("authorizer_appid", authorizerAppId);String refreshToken;if (redisUtils.hasKey(CacheKey.AUTH_REFRESH_TOKEN + authorizerAppId)) {refreshToken = (String) redisUtils.get(CacheKey.AUTH_REFRESH_TOKEN + authorizerAppId);} else {//從微信第三方管理工具的數(shù)據(jù)庫中查詢出authorizer_refresh_tokenrefreshToken = platformMapper.selectRefreshTokenByAppId(authorizerAppId);if (StringUtils.isBlank(refreshToken)) {throw new BadRequestException("小程序管理員未授權(quán)，請讓小程序管理員重新授權(quán)");}//計(jì)算刷新令牌的過期時(shí)間//從微信第三方管理工具的數(shù)據(jù)庫中查詢出authorizer_refresh_token的過期時(shí)間LocalDateTime authTime = platformMapper.selectAuthTimeByAppId(authorizerAppId).toLocalDateTime();Duration duration = Duration.between(authTime, LocalDateTime.now());redisUtils.set(CacheKey.AUTH_REFRESH_TOKEN + authorizerAppId, refreshToken, 60 * 60 * 24 * 30 - (duration.toMillis() / 1000 + 60));}param.put("authorizer_refresh_token", refreshToken);JSONObject tokenData = JSONObject.parseObject(HttpUtil.post(refreshTokenUrl, JSON.toJSONString(param)));if (tokenData.containsKey("authorizer_access_token")) {redisUtils.set(CacheKey.AUTH_ACCESS_TOKEN + authorizerAppId, tokenData.getString("authorizer_access_token"), 2 * 60 * 60);LambdaUpdateWrapper<SpiritOpenPlatform> updateWrapper = new LambdaUpdateWrapper<>();updateWrapper.eq(SpiritOpenPlatform::getAppid, authorizerAppId);SpiritOpenPlatform openPlatform = new SpiritOpenPlatform();openPlatform.setAuthorizerRefreshToken(refreshToken);openPlatform.setAuthorizerAccessToken(tokenData.getString("authorizer_access_token"));platformMapper.update(openPlatform, updateWrapper);return;}throw new BadRequestException("獲取authorizer_access_token失敗,接口返回信息：" + tokenData.toJSONString()); }

到此，微信第三方平臺開發(fā)中的關(guān)鍵token，authorizer_access_token已經(jīng)成功獲取

4、調(diào)接口發(fā)布小程序

提交代碼接口：上傳小程序代碼并生成體驗(yàn)版 | 微信開放文檔 (qq.com)

設(shè)置用戶隱私接口：配置小程序用戶隱私保護(hù)指引 | 微信開放文檔 (qq.com)

提交審核接口：提交審核 | 微信開放文檔 (qq.com)

查詢審核結(jié)果接口：查詢最新一次提交的審核狀態(tài) | 微信開放文檔 (qq.com)

• 項(xiàng)目中可以采用定時(shí)任務(wù)的策略調(diào)用該接口

最后

總結(jié)：微信第三方平臺開發(fā)的流程，涉及的接口有點(diǎn)多，微信的文檔其實(shí)也寫的很詳細(xì)了，但是在開發(fā)過程中，免不了遇見莫名其妙的問題，這個(gè)時(shí)候可以在微信開放社區(qū)里找找或者搜下博客。

總結(jié)
