篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了微信公众平台 客服接口-发消息相关的知识,希望对你有一定的参考价值。
微信公众平台技术文档:客服消息
一、接口说明
当用户和公众号产生特定动作的交互时(具体动作列表请见下方说明),微信将会把消息数据推送给开发者,开发者可以在一段时间内(目前修改为48小时)调用客服接口,通过POST一个JSON数据包来发送消息给普通用户。此接口主要用于客服等有人工消息处理环节的功能,方便开发者为用户提供更加优质的服务。
目前允许的动作列表如下(公众平台会根据运营情况更新该列表,不同动作触发后,允许的客服接口下发消息条数不同,下发条数达到上限后,会遇到错误返回码,具体请见返回码说明页):
1、用户发送信息
2、点击自定义菜单(仅有点击推事件、扫码推事件、扫码推事件且弹出“消息接收中”提示框这3种菜单类型是会触发客服接口的)
3、关注公众号
4、扫描二维码
5、支付成功
6、用户维权
二、客服接口-发消息
1 接口调用请求说明
http请求方式: POST
https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=ACCESS_TOKEN
2 发送客服消息
各消息类型所需的JSON数据包如下:
(1)发送文本消息
"touser":"OPENID",
"msgtype":"text",
"text":
"content":"Hello World"
(2)发送图片消息
"touser":"OPENID",
"msgtype":"image",
"image":
"media_id":"MEDIA_ID"
(3)发送语音消息
"touser":"OPENID",
"msgtype":"voice",
"voice":
"media_id":"MEDIA_ID"
(4)发送视频消息
"touser":"OPENID",
"msgtype":"video",
"video":
"media_id":"MEDIA_ID",
"thumb_media_id":"MEDIA_ID",
"title":"TITLE",
"description":"DESCRIPTION"
(5)发送音乐消息
"touser":"OPENID",
"msgtype":"music",
"music":
"title":"MUSIC_TITLE",
"description":"MUSIC_DESCRIPTION",
"musicurl":"MUSIC_URL",
"hqmusicurl":"HQ_MUSIC_URL",
"thumb_media_id":"THUMB_MEDIA_ID"
(6)发送图文消息(点击跳转到外链) 图文消息条数限制在8条以内,注意,如果图文数超过8,则将会无响应。
"touser":"OPENID",
"msgtype":"news",
"news":
"articles": [
"title":"Happy Day",
"description":"Is Really A Happy Day",
"url":"URL",
"picurl":"PIC_URL"
,
"title":"Happy Day",
"description":"Is Really A Happy Day",
"url":"URL",
"picurl":"PIC_URL"
]
(7)发送图文消息(点击跳转到图文消息页面) 图文消息条数限制在8条以内,注意,如果图文数超过8,则将会无响应。
"touser":"OPENID",
"msgtype":"mpnews",
"mpnews":
"media_id":"MEDIA_ID"
(8)发送卡券
"touser":"OPENID",
"msgtype":"wxcard",
"wxcard":
"card_id":"123dsdajkasd231jhksad"
,
特别注意客服消息接口投放卡券仅支持非自定义Code码和导入code模式的卡券的卡券,详情请见:是否自定义code码。
请注意,如果需要以某个客服帐号来发消息(在微信6.0.2及以上版本中显示自定义头像),则需在JSON数据包的后半部分加入customservice参数,例如发送文本消息则改为:
"touser":"OPENID",
"msgtype":"text",
"text":
"content":"Hello World"
,
"customservice":
"kf_account": "test1@kftest"

@Override
public WeixinResponse sendMessage(String accessToken, Message message)
WeixinResponse weixinResponse = null;
String url = new StringBuffer(serviceHost).append("/cgi-bin/message/custom/send?access_token=")
.append(accessToken).toString();

5 接口实例开发
/**
* 发送客服消息
* @param openId 要发给的用户
* @param accessToken 微信公众号token
* @param weixinAppId 微信公众号APPID
*/
private void sendCustomMessage(String openId,String accessToken,String weixinAppId)
try
RestTemplate rest = new RestTemplate();
String postUrl = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" + accessToken;
//推送图文消息
Message message = new Message();
message.setTouser(openId);//普通用户openid
message.setMsgtype("news");//图文消息(点击跳转到外链)为news
Articles news = new Articles();
Article article = new Article();
article.setDescription("客服消息图文描述");//图文消息/视频消息/音乐消息的描述
article.setPicurl("http://mmbiz.qpic.cn/mmbiz_jpg/CDW6Ticice130g6RcXCkNNDWic4dEaAHQDia2OG5atHBqSvsPuCfuqoyeeLWENia4ciaKt3KHWQ9t2LRPDpUo5AkOyyA/0");//图文消息的图片链接,支持JPG、PNG格式,较好的效果为大图640*320,小图80*80
article.setTitle("客服消息图文标题");//图文消息/视频消息/音乐消息的标题
//图文推送链接
String url="https://www.baidu.com";
article.setUrl(url);//图文消息被点击后跳转的链接
Article[] articles = article;
news.setArticles(articles);
message.setNews(news);
int i=1;
while(i<=3)//循环发送3次
WeixinResponse response = rest.postForObject(postUrl, message, WeixinResponse.class, new HashMap<String,String>());
LOG.info("发送客服消息返回信息:"+response.toString());
if(response.getErrcode()==0)//发送成功-退出循环发送
i=4;
break;
else
i++;//发送失败-继续循环发送
catch (Exception e)
LOG.error("发送客服消息失败,openId="+openId,e);
6 客服接口图文推送上传图片
在发送图文消息时,我们需要添加图片的地址,介绍一个好方法。
(1)进入微信公众平台接口调试工具
https://mp.weixin.qq.com/debug
(2)选择类型和列表
接口类型:基础支持
接口列表:上传logo接口/media/uploadimg
添加access_token,选择类型是image,最后选择文件
注:添加视频、音乐是一样的
(3)最后就会生成图片的url
(4)在浏览器访问url即可看见生成的图片
