背景

最近公司項(xiàng)目一直在圍繞著支付寶做應(yīng)用開發(fā)，為了能保證消息能夠及時的給用戶傳遞，因此需要開發(fā)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

事先準(zhǔn)備

1、請仔細(xì)閱讀支付寶模板消息發(fā)送指引：模板消息指引
2、仔細(xì)閱讀用戶的授權(quán)文檔，用戶授權(quán)的詳細(xì)的實(shí)現(xiàn)步驟可以見我寫的另外一篇文章：《PHP實(shí)現(xiàn)支付寶小程序用戶授權(quán)的工具類》
3、在小程序中加入模板消息的權(quán)限，如下圖

4、仔細(xì)閱讀支付寶發(fā)送模板消息接口文檔：alipay.open.app.mini.templatemessage.send
5、事先通過小程序的form組件收集好對一個的formid，formid組件文檔
6、將小程序綁定到生活號上
7、配置一個模板消息編號，詳細(xì)步驟：小程序--->模板消息，最終配置號的模板消息如下

實(shí)現(xiàn)流程

1、通過客戶端的form組件，收集好formid，并多帶帶開一個后端接口將formid通過http請求保存到后臺，最好是盡可能多的收集formid，比如按鈕的點(diǎn)擊事件、tab的切換上都可以增加formid組件
2、通過調(diào)用alipay.open.app.mini.templatemessage.send接口，給客戶端發(fā)送模板消息，注意支付寶所有的模板消息都是基于生活號進(jìn)行分發(fā)的，所以事先一定要綁定好對應(yīng)的生活號

實(shí)現(xiàn)方法 相關(guān)常量

//模板消息的接口方法名稱
const API_METHOD_SEND_TPL_MSG = "alipay.open.app.mini.templatemessage.send";
//模板消息的結(jié)果返回節(jié)點(diǎn)名稱
const RESPONSE_OUTER_NODE_SEND_TPL_MSG = "alipay_open_app_mini_templatemessage_send_response";

入口方法

/**
     * 發(fā)送小程序模板消息
     * @param $formId
     * @param $to 發(fā)送給用戶的編號
     * @param $tplId 模板編號
     * @param $tplContent 模板內(nèi)容
     * @param $page 要跳轉(zhuǎn)的頁面
     * @return array
     */
    public static function sendAmpTplMsg($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;
    }

獲取基礎(chǔ)參數(shù)方法

/**
     * 獲取發(fā)送模板消息的接口參數(shù)
     */
    protected static function getTplMsgBaseParam($formId,$to,$tplId,$tplContent,$page = ""){
        $baseParam = [
            "to_user_id" => $to,
            "form_id" => $formId,
            "user_template_id" => $tplId,
            "page" => $page,
            "data" => $tplContent,
        ];
        $bizContent = json_encode($baseParam,JSON_UNESCAPED_UNICODE);
        $busiParam = [
            "biz_content" => $bizContent
        ];
        $param = self::buildApiBuisinessParam($busiParam,self::API_METHOD_SEND_TPL_MSG);
        return $param;
    }
    
    /**
     * 構(gòu)建業(yè)務(wù)參數(shù)
     */
    protected static function buildApiBuisinessParam($businessParam,$apiMethod){
        $pubParam = self::getApiPubParam($apiMethod);
        $businessParam = array_merge($pubParam,$businessParam);
        $signContent = self::getSignContent($businessParam);
        error_log("sign_content ===========>".$signContent);
        $rsaHelper = new RsaHelper();
        $sign = $rsaHelper->createSign($signContent);
        error_log("sign ===========>".$sign);
        $businessParam["sign"] = $sign;
        return $businessParam;
    }
    
    /**
     * 公共參數(shù)
     *
     */
    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;
    }
    
    /**
     * 獲取簽名的內(nèi)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;
    }
    
    /**
     * 構(gòu)建請求鏈接
     */
    protected static function buildRequestUrl($param){
        $paramStr = http_build_query($param);
        return self::API_DOMAIN . $paramStr;
    }

獲取返回的結(jié)果值

/**
     * 獲取返回的數(shù)據(jù)，對返回的結(jié)果做進(jìn)一步的封裝和解析
     */
    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;
    }

返回結(jié)果

如果返回的節(jié)點(diǎn)code為10000,則表示消息發(fā)送

{
    "alipay_open_app_mini_templatemessage_send_response":{
        "code":"10000",
        "msg":"Success"
      }
    ,"sign":"ERITJKEIJKJHKKKKKKKHJEREEEEEEEEEEE"
}

調(diào)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" => "點(diǎn)我查看詳情",
    ],
];
$result = AmpHelper::sendAmpTplMsg($formId,$openId,$tplId,$content,$page= "pages/index/index");
