Tp5微信小程序模板消息，公衆號模板消息，獲取地理位置

寫了幾個常用的微信接口，項目時間過於緊迫，未經整理，留待有空時再來整理或者擴展吧。

建議大家使用前，先去微信官方文檔那邊看一看，雖然微信的文檔着實有點坑，但是總歸還是能瞭解大概的業務邏輯以及找到一些排錯手段來使用。

使用方式：

//引入微信操作類

use think\Wechatmsg;

//發送小程序模板消息

$data['openid'] = '你的微信小程序appid';
        $data['template_id'] = '小程序模板id';
        $data['page'] = '需要跳轉的小程序頁面路徑';
        $data['data'] = array(
            'keyword1' => array("value" => '123', "color" => "#4a4a4a"),
            'phrase1' => array("value" => '審覈'),
            'thing2' => array("value" => '審覈結果'),
            'date3' => array("value" => date('Y-m-d', time())),
            'date4' => array("value" => date('Y-m-d', time())),
            'thing7' => array("value" => '審覈結果'),
        );
        WeChatmsg::send_msg($data);

//發送公衆號模板消息

$data['openid'] = '你的公衆號appid';
        $data['template_id'] = '你的公衆號模板id';
        $data['url'] = '需要跳轉的路徑';
        $data['data'] = array(
            'keyword1' => array("value" => date('Y-m-d', time()), "color" => "#4a4a4a"),//提現時間
            'keyword2' => array("value" => date('Y-m-d', time())),//到賬時間
            'keyword3' => array("value" => 100),//到賬金額
            'keyword4' => array("value" => 111),//賬戶餘額
            'remark' => array('value' => '測試推送')
        );
        WeChatmsg::pushMessage($data);

//獲取地理位置

//此處要說明一下，後端的微信地理位置的獲取並不能直接獲取到地址，只是獲取到前端所需的jsapi_ticket和簽名等信息，前端拿到後再請求微信接口即可拿到經緯度信息。注意：拿到jsapi_ticket和access_token的時候，一定要做緩存的操作，這兩個東西微信都有調用次數限制，微信那邊的有效時長爲7200s，本地可根據此時間做一定的緩存操作。

//$url指的是當前頁面所在地址，具體是使用後端動態獲取還是由前端傳入，要看具體項目情況，我使用的是前端傳入的方式，之所以使用了urldecode是因爲項目過程中發生了個奇怪現象，url在傳輸過程中出現了被轉義的情況，使用時根據自己的情況選擇一下就OK。


Wechatmsg::getSignPackage(urldecode($url))

總結：
第一、以上代碼親測可用
第二、細看文檔
第三、相信微信，出問題了絕對是自己的鍋
第四、相信微信，出問題了絕對是自己的鍋
第五、相信微信，出問題了絕對是自己的鍋
重要的事情說三遍。
出現報錯的時候不要慌，報錯複製出來百度，或者去微信官方文檔查看錯誤代碼，我在調試過程中調用以上代碼時也是報錯無數，但每次都是我背鍋，不是微信小程序或者公衆號配置有問題，就是簽名或者其他奇葩的地方有問題
最後，微信真坑。
