      登錄微信公眾平臺(tái)，點(diǎn)擊添加插件，把模板消息添加到功能中

添加插件

2、添加我的模板

點(diǎn)擊模板消息之后呢會(huì)出現(xiàn)我的模板和模板庫(kù)，我們點(diǎn)擊模板庫(kù)在模板庫(kù)中選擇自己想要的模板或者提交申請(qǐng)自己新建的模板(點(diǎn)擊完善模板庫(kù))，微信要審核比較慢，一個(gè)月只能提交3次，模板庫(kù)就沒(méi)有限制

點(diǎn)擊詳情，添加即可

添加之后就可以在我的模板庫(kù)中看到你添加的模板，點(diǎn)擊詳情

可以看到模板ID和模板需要的參數(shù)

3、請(qǐng)求接口發(fā)送模板消息

點(diǎn)擊模板消息文檔可以看到微信提供的文檔，查看需要請(qǐng)求的接口

需要一個(gè)參數(shù)access_token

繼續(xù)看需要封裝的參數(shù),是一個(gè)json

構(gòu)建發(fā)送消息模板對(duì)象

/** 跟上圖json對(duì)應(yīng) */
public class WechatTemplateReq {

    private String touser;
    /** 模板Id */
    private String template_id;
    /** 跳轉(zhuǎn)url */
    private String url;
    /** 參數(shù) key為參數(shù)名 --- value為參數(shù)值和顏色 */
    private Map<String, FirstBean> data;
}
public class FirstBean {
    /** 值 */
