Tp5微信小程序模板消息，公众号模板消息，获取地理位置

 写了几个常用的微信接口，项目时间过于紧迫，未经整理，留待有空时再来整理或者扩展吧。

建议大家使用前，先去微信官方文档那边看一看，虽然微信的文档着实有点坑，但是总归还是能了解大概的业务逻辑以及找到一些排错手段来使用。

 使用方式：

//引入微信操作类

use think\Wechatmsg;

//发送小程序模板消息

$data['openid'] = '你的微信小程序appid';
        $data['template_id'] = '小程序模板id';
        $data['page'] = '需要跳转的小程序页面路径';
        $data['data'] = array(
            'keyword1' => array("value" => '123', "color" => "#4a4a4a"),

            'thing7' => array("value" => '审核结果'),
        );
        WeChatmsg::send_msg($data);

//发送公众号模板消息

$data['openid'] = '你的公众号appid';
        $data['template_id'] = '你的公众号模板id';
        $data['url'] = '需要跳转的路径';
        $data['data'] = array(

            'keyword2' => array("value" => date('Y-m-d', time())),//到账时间
            'keyword3' => array("value" => 100),//到账金额
            'keyword4' => array("value" => 111),//账户余额
            'remark' => array('value' => '测试推送')
        );
        WeChatmsg::pushMessage($data);

//获取地理位置

//此处要说明一下，后端的微信地理位置的获取并不能直接获取到地址，只是获取到前端所需的jsapi_ticket和签名等信息，前端拿到后再请求微信接口即可拿到经纬度信息。注意：拿到jsapi_ticket和access_token的时候，一定要做缓存的操作，这两个东西微信都有调用次数限制，微信那边的有效时长为7200s，本地可根据此时间做一定的缓存操作。

//$url指的是当前页面所在地址，具体是使用后端动态获取还是由前端传入，要看具体项目情况，我使用的是前端传入的方式，之所以使用了urldecode是因为项目过程中发生了个奇怪现象，url在传输过程中出现了被转义的情况，使用时根据自己的情况选择一下就OK。

Wechatmsg::getSignPackage(urldecode($url))

总结：
第一、以上代码亲测可用
第二、细看文档
第三、相信微信，出问题了绝对是自己的锅
第四、相信微信，出问题了绝对是自己的锅
第五、相信微信，出问题了绝对是自己的锅
重要的事情说三遍。
出现报错的时候不要慌，报错复制出来百度，或者去微信官方文档查看错误代码，我在调试过程中调用以上代码时也是报错无数，但每次都是我背锅，不是微信小程序或者公众号配置有问题，就是签名或者其他奇葩的地方有问题
最后，微信真坑。
