java 微信小程序-发送模板消息

开发前准备工作

/**

	    JSONObject jsonObject = WeChatUtil.httpRequest(requestUrl, "GET", null);  //调用通用的https请求方法  
	    // 如果请求成功    
	    if (null != jsonObject) {

发送模板消息接口

封装模板类

public class WxMssVo {
	private String touser;//用户openid
	private String template_id;//模版id
	private String page = "pages/MyOrder/MyOrderDetail";// 订单详情页
	private String form_id;//收集到的用户formid
	//    private String emphasis_keyword = "keyword1.DATA";//放大那个推送字段
	private Map<String, TemplateDataVo> data;//推送文字

	public String getTouser() {
		return touser;
	}

	public void setTouser(String touser) {
		this.touser = touser;
	}

	public String getTemplate_id() {
		return template_id;
	}

	public void setTemplate_id(String template_id) {
		this.template_id = template_id;
	}

	public String getPage() {
		return page;
	}

	public void setPage(String page) {
		this.page = page;
	}

	public String getForm_id() {
		return form_id;
	}

	public void setForm_id(String form_id) {
		this.form_id = form_id;
	}

	public Map<String, TemplateDataVo> getData() {
		return data;
	}

	public void setData(Map<String, TemplateDataVo> data) {
		this.data = data;
	}
}
