這裏是我分享的小程序後端php發送模板消息的接口,其中有許多要注意的地方.
注意!注意!注意!重要的事情說三遍!獲取access_token,是需要了解的
access_token 是全局唯一接口調用憑據，開發者調用各接口時都需使用 access_token，請妥善保存。access_token 的存儲至少要保留512個字符空間。access_token 的有效期目前爲2個小時，需定時刷新，重複獲取將導致上次獲取的 access_token 失效。
/**
* 發送模板消息
*/
public function TemplateMessage()
{
// Initialize Variable
$pid = I('goodid');
$touser = I('touser');//接收者openid
$template_id = I('template_id');//模板id
$page = I('page');//點擊跳轉頁面,可帶參數
$form_id = I('form_id');//formId
$keyword1 = I('keyword1');//商品名
$keyword2 = I('keyword2');//商品原價
$keyword3 = I('keyword3');//支付金額
$keyword4 = I('keyword4');//溫馨提示
//獲取access_token
$this->miniapp_init();
$sAccessToken = $this->AccessToken();
// 模板消息內容
$arrTemplateValue = [
"keyword1" => ["value"=>$keyword1],
"keyword2" => ["value"=>$keyword2],

"keyword4" => ["value"=>$keyword4],
];
$sUrl = 'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token='.$sAccessToken;

'touser' => $touser,
'template_id' => $template_id,
'page' => $page,
'form_id' => $form_id,

];
$result = $this->https_curl_json($sUrl, $arrList, 'json');
echo json_encode($result);
}

獲取access_token,配置信息請自行配置,這裏就不做過多解釋
