微信小程序 几步实现模版消息的发送

1.首先先创建一个简单的wxml页面，包括一个简单的form表单：

 

特别注意必须加上report-submit=\'true\'

 

2.获取用户(要发送的用户)的openid

js代码：

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function(options) {
    wx.login({
      success: function(res) {
        wx.request({
          url: app.globalData.myUrl + \'/ce/php/main.php\',//请求的url,视自己情况而定，我用的php后台
          data: {
            type: "openid",
            js_code: res.code//将js_code传到后台
          },
          success: function(res) {
            console.log(res.data.openid);
            wx.setStorageSync("openid", res.data.openid)//将用户openid存起来
          }
        })
      }
    })
  }

　　php后台代码（请求api获取到openid）：

	case \'openid\':
		$js_code = $_REQUEST["js_code"];//接收前台传来的js_code
		$appid = "wx084xxxxxxxxxxf6fc";//appid(需要到小程序官网上查看自己的appid和appSerect)
		$appSerect = "4b435xxxxxxxx5ba4bdxxxxxx3f99ee7";
		$api = "https://api.weixin.qq.com/sns/jscode2session?appid={$appid}&secret={$appSerect}&js_code={$js_code}&grant_type=authorization_code";

		function httpGet($url)
		{
			$curl = curl_init();
			curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
			curl_setopt($curl, CURLOPT_TIMEOUT, 500);
			curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
			curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
			curl_setopt($curl, CURLOPT_URL, $url);
			$res = curl_exec($curl);
			curl_close($curl);
			return $res;
		}
		$str = httpGet($api);
		echo $str;
		break;

3.获取access_token

  orderSign: function(e) {
    console.log(e)
    wx.request({
      url: \'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wx0xxxxxxxxxxxx6fc&secret=4b43xxxxxxxxxxxxxxxe3f99ee7\',
      data: {},
      success: function(res) {
        var openid = wx.getStorageSync("openid")//取前一步存起来的openid
        wx.request({
          url: \'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=\' + res.data.access_token,//获取的access_token
          data: {
            "touser": openid,//要发送的用户的openid
            "template_id": \'L8hCIxb9K1fQ85yAn6C5J4eAxfruNyALTG_mfE01K4U\',//模版ID
            "form_id": e.detail.formId,//获取的formid
            "data": {//模版数据
              "keyword1": {
                "value": "2018年3月26日",
                "color": "#173177"
              },
              "keyword2": {
                "value": "扫一扫",
                "color": "#173177"
              },
              "keyword3": {
                "value": "1000元",
                "color": "#173177"
              },
              "keyword4": {
                "value": "测试的商户详情",
                "color": "#173177"
              },
              "keyword5": {
                "value": "6546546846544-1w",
                "color": "#173177"
              }
            },
            "emphasis_keyword": "keyword3.DATA"//需要放大显示的数据
          },
          method: \'post\',
          header: {
            \'content-type\': \'application/json\' // 默认值
          },
          success: function(res) {
            console.log(res.data)
          }
        })
      }
    })
  }

　模版id需要在小程序官网上获取：

 

完成这几步之后，点击提交按钮，表单提交成功后就可以成功发送模版消息！！
