微信小程序消息模板

wxml:

<form bindsubmit='sendSms' report-submit='true' id='fo'>
  <button form-type='submit'>发送模板消息</button>
</form>

js:

sendSms:function(e){
    var formId = e.detail.formId;
    wx.login({
      success:function(res){
        wx.request({
          url: 'https://xxxxxx.com/wxtest/getopenid.php',
          data: {
            code: res.code,
            formId:formId
          },
          header: {
            'content-type': 'application/json' // 默认值
          },
          success(res) {
            console.log(res.data)
          }
        })
      }
    })
  },
