微信公众平台技术文档:

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:。

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"
 }
}

3 请求参数说明

参数 是否必须 说明
access_token 调用接口凭证
touser 普通用户openid
msgtype 消息类型,文本为text,图片为image,语音为voice,视频消息为video,音乐消息为music,图文消息(点击跳转到外链)为news,图文消息(点击跳转到图文消息页面)为mpnews,卡券为wxcard

 }

 @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();
  weixinresponse = resttemplate.postforobject(url, message, weixinresponse.class);

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


(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

微信公众平台 客服接口发消息的实现代码(Java接口开发) 

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
