需求，从接口获取模板列表，并对获取到模板进行赋值

尝试多次，主要在构造data数组的地方：

$app=util::getWeiXin();

        $api = $app->getClient();

        $response = $api->post('/cgi-bin/template/get_all_private_template');

        $tempateList=$response->toArray();



        //尝试发送一条模板消息 

        //随机一个模板消息

        $randNum=rand(0,count($tempateList['template_list'])-1);

        $template=$tempateList['template_list'][$randNum];

        //匹配变量

        preg_match_all('~{{(.*)}}~',$template['content'],$match);

        $keyword=[];

        foreach ($match[1] as $k=>$v){

            $key=substr($v,0,strpos($v,'.'));

            $keyword[$key]['value']='测试新'.($k+1);

            if (strpos($key,'time')!==false){

                $keyword[$key]['value']=date('Y-m-d H:i:s');

            }

            if (strpos($key,'amount')!==false){

                $keyword[$key]['value']=rand(1000,2000);

            }

            if (strpos($key,'character')!==false){

                $keyword[$key]['value']=uniqid();

            }

        }

        //发送模板消息

        $response = $api->post('/cgi-bin/message/template/send', [

            'json' => [

                "touser" => "openid",

                "template_id" => $template['template_id'],

                "url" => "http://www.baidu.com",

                "data"=> $keyword

            ]

        ]);

        var_dump($response->getContent());
