背景
最近公司项目一直在围绕着支付宝做应用开发,为了能保证消息能够及时的给用户传递,因此需要开发模板消息的功能,而小程序的模板消息也是最快捷的通知方式
事先准备
1、请仔细阅读支付宝模板消息发送指引:模板消息指引
2、仔细阅读用户的授权文档,用户授权的详细的实现步骤可以见我写的另外一篇文章:《PHP实现支付宝小程序用户授权的工具类》
3、在小程序中加入模板消息的权限,如下图
4、仔细阅读支付宝发送模板消息接口文档:alipay.open.app.mini.templatemessage.send
5、事先通过小程序的form组件收集好对一个的formid,formid组件文档
6、将小程序绑定到生活号上
7、配置一个模板消息编号,详细步骤:小程序--->模板消息,最终配置号的模板消息如下
实现流程
1、通过客户端的form组件,收集好formid,并单独开一个后端接口将formid通过http请求保存到后台,最好是尽可能多的收集formid,比如按钮的点击事件、tab的切换上都可以增加formid组件
2、通过调用alipay.open.app.mini.templatemessage.send接口,给客户端发送模板消息 ,注意支付宝所有的模板消息都是基于生活号进行分发的,所以事先一定要绑定好对应的生活号
实现方法
相关常量
//模板消息的接口方法名称
const API_METHOD_SEND_TPL_MSG = 'alipay.open.app.mini.templatemessage.send';
//模板消息的结果返回节点名称
const RESPONSE_OUTER_NODE_SEND_TPL_MSG = 'alipay_open_app_mini_templatemessage_send_response';
入口方法
/**
* 发送小程序模板消息
* @param $formId
* @param $to 发送给用户的编号
* @param $tplId 模板编号
* @param $tplContent 模板内容
* @param $page 要跳转的页面
* @return array
*/
public static function sendAmpTplMsg($formId,$to,$tplId,$tplContent,$page = ''){
$param = self::getTplMsgBaseParam($formId,$to,$tplId,$tplContent,$page = '');
$url = self::buildRequestUrl($param);
$response = self::getResponse($url,self::RESPONSE_OUTER_NODE_SEND_TPL_MSG);
return $response;
}
获取基础参数方法
/**

*/
protected static function getTplMsgBaseParam($formId,$to,$tplId,$tplContent,$page = ''){
$baseParam = [
'to_user_id' => $to,
'form_id' => $formId,

];
$param = self::buildApiBuisinessParam($busiParam,self::API_METHOD_SEND_TPL_MSG);

}
/**

*/

$signContent = self::getSignContent($businessParam);
error_log('sign_content ===========>'.$signContent);
$rsaHelper = new RsaHelper();
$sign = $rsaHelper->createSign($signContent);
error_log('sign ===========>'.$sign);
$businessParam['sign'] = $sign;
return $businessParam;
}
/**
* 公共参数
*
*/
protected static function getApiPubParam($apiMethod){
$ampBaseInfo = BusinessHelper::getAmpBaseInfo();
$param = [
'timestamp' => date('Y-m-d H:i:s') ,
'method' => $apiMethod,
'app_id' => formatArrValue($ampBaseInfo,'appid',config('param.amp.appid')),
'sign_type' =>self::SIGN_TYPE_RSA2,
'charset' =>self::FILE_CHARSET_UTF8,
'version' =>self::VERSION,
];
return $param;
}
/**
* 获取签名的内容
*/
protected static function getSignContent($params) {
ksort($params);
$stringToBeSigned = "";
$i = 0;
foreach ($params as $k => $v) {
if (!empty($v) && "@" != substr($v, 0, 1)) {
if ($i == 0) {
$stringToBeSigned .= "$k" . "=" . "$v";
} else {
$stringToBeSigned .= "&" . "$k" . "=" . "$v";
}
$i++;
}
}
unset ($k, $v);
return $stringToBeSigned;
}
/**
* 构建请求链接
*/
protected static function buildRequestUrl($param){
$paramStr = http_build_query($param);
return self::API_DOMAIN . $paramStr;
}
获取返回的结果值
/**
* 获取返回的数据,对返回的结果做进一步的封装和解析
*/
protected static function getResponse($url,$responseNode){
$json = curlRequest($url);
error_log("result is =========>".$json);
$response = json_decode($json,true);
$responseContent = formatArrValue($response,$responseNode,[]);
$errResponse = formatArrValue($response,self::RESPONSE_OUTER_NODE_ERROR_RESPONSE,[]);
if($errResponse){
return $errResponse;
}
return $responseContent;
}
返回结果
如果返回的节点code为10000,则表示消息发送
{
"alipay_open_app_mini_templatemessage_send_response":{
"code":"10000",
"msg":"Success"
}
,"sign":"ERITJKEIJKJHKKKKKKKHJEREEEEEEEEEEE"
}
调用
$formId = 'MjA4ODMwMjI2MjE4Mzc4MF8xNTQ2ODQ0MTUyNzU0XzA1NQ==';
$openId = '2088302262183780';
$tplId = 'Mzc4OTk2ODU1YzM4NTI3NmY5ZjI2OTdhNGNkZDE2NGQ=';
$content = [
'keyword1' => [
'value' => '您的朋友【】偷去了你的能量啦~',
],
'keyword2' => [
'value' => '朋友偷能量提醒',
],
'keyword3' => [
'value' => '点我查看详情',
],
];
$result = AmpHelper::sendAmpTplMsg($formId,$openId,$tplId,$content,$page= 'pages/index/index');
