MP_群发消息

下面用用户列表群发（WxMpMassOpenIdsMessage）做例子，如果要使用标签群发，则使用me.chanjar.weixin.mp.bean.WxMpMassTagMessage即可。 更多用例，请参考单元测试类：me.chanjar.weixin.mp.api.impl.WxMpMassMessageServiceImplTest

文本消息

WxMpMassOpenIdsMessage massMessage = new WxMpMassOpenIdsMessage();
massMessage.setMsgType(WxConsts.MASS_MSG_TEXT);
massMessage.setContent("消息内容");
massMessage.getToUsers().add(openid);

WxMpMassSendResult massResult = wxMpService.getMassMessageService().massOpenIdsMessageSend(massMessage);

视频消息

WxMediaUploadResult uploadMediaRes = wxMpService.getMaterialService().mediaUpload(WxConsts.MEDIA_VIDEO, "mp4", inputStream);

// 把视频变成可被群发的媒体
WxMpMassVideo video = new WxMpMassVideo();
video.setTitle("测试标题");
video.setDescription("测试描述");
video.setMediaId(uploadMediaRes.getMediaId());
WxMpMassUploadResult uploadResult = wxMpService.getMassMessageService().massVideoUpload(video);

WxMpMassOpenIdsMessage massMessage = new WxMpMassOpenIdsMessage();
massMessage.setMsgType(WxConsts.MASS_MSG_VIDEO);
massMessage.setMediaId(uploadResult.getMediaId());
massMessage.getToUsers().add(openid);

WxMpMassSendResult massResult = wxMpService.getMassMessageService().massOpenIdsMessageSend(massMessage);

图片消息

WxMediaUploadResult uploadMediaRes = wxMpService.getMaterialService().mediaUpload(WxConsts.MEDIA_IMAGE, "jpg", inputStream);

WxMpMassOpenIdsMessage massMessage = new WxMpMassOpenIdsMessage();
massMessage.setMsgType(WxConsts.MASS_MSG_IMAGE);
massMessage.setMediaId(uploadMediaRes.getMediaId());
massMessage.getToUsers().add(openid);

WxMpMassSendResult massResult = wxMpService.getMassMessageService().massOpenIdsMessageSend(massMessage);

语音消息

WxMediaUploadResult uploadMediaRes = wxMpService.getMaterialService().mediaUpload(WxConsts.MEDIA_VOICE, "mp3", inputStream);

WxMpMassOpenIdsMessage massMessage = new WxMpMassOpenIdsMessage();
massMessage.setMsgType(WxConsts.MASS_MSG_VOICE);
massMessage.setMediaId(uploadMediaRes.getMediaId());
massMessage.getToUsers().add(openid);

WxMpMassSendResult massResult = wxMpService.getMassMessageService().massOpenIdsMessageSend(massMessage);

图文消息

    // 上传图文消息的封面图片
    WxMediaUploadResult uploadMediaRes = wxMpService.getMaterialService().mediaUpload(WxConsts.MediaFileType.IMAGE, "jpg", inputStream);

    // 上传图文消息的正文图片(返回的url拼在正文的<img>标签中)
    WxMediaImgUploadResult imagedMediaRes = wxMpService.getMaterialService().mediaImgUpload(file);
    String url=imagedMediaRes.getUrl();

    WxMpMassNews news = new WxMpMassNews();
    WxMpNewsArticle article1 = new WxMpNewsArticle();
    article1.setTitle("标题1");
    article1.setContent("内容1");
    article1.setThumbMediaId(uploadMediaRes.getMediaId());
    news.addArticle(article1);

    WxMpNewsArticle article2 = new WxMpNewsArticle();
    article2.setTitle("标题2");
    article2.setContent("内容2");
    article2.setThumbMediaId(uploadMediaRes.getMediaId());
    article2.setShowCoverPic(true);
    article2.setAuthor("作者2");
    article2.setContentSourceUrl("www.baidu.com");
    article2.setDigest("摘要2");
    news.addArticle(article2);

    WxMpMassUploadResult massUploadResult = wxMpService.getMassMessageService().massNewsUpload(news);

    WxMpMassOpenIdsMessage massMessage = new WxMpMassOpenIdsMessage();
    massMessage.setMsgType(WxConsts.MassMsgType.MPNEWS);
    massMessage.setMediaId(uploadResult.getMediaId());
    massMessage.getToUsers().add(openid);

    WxMpMassSendResult massResult = wxMpService.getMassMessageService().massOpenIdsMessageSend(massMessage);
