ThinkPHP5.0微信開發之獲取使用者地理位置

  • 新建一個類Location.php 我直接貼程式碼,要用大夥自己複製下就OK!
<?php
class Locatin{
    private $appId;
    private $appSecret;
    public function __construct($appId, $appSecret) {
        $this->appId = $appId;
        $this->appSecret = $appSecret;
    }
    public function getSignPackage() {
        $jsapiTicket
= $this->getJsApiTicket(); // 注意 URL 一定要動態獲取,不能 hardcode. $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://"; $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $timestamp = time(); $nonceStr
= $this->createNonceStr(); // 這裡引數的順序要按照 key 值 ASCII 碼升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url"; $signature = sha1($string); $signPackage = array( "appId" => $this->appId, "nonceStr"
=> $nonceStr, "timestamp" => $timestamp, "url" => $url, "signature" => $signature, "rawString" => $string ); return $signPackage; } private function createNonceStr($length = 16) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $str = ""; for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } private function getJsApiTicket() { // jsapi_ticket 應該全域性儲存與更新,以下程式碼以寫入到檔案中做示例 $data = json_decode($this->get_php_file("jsapi_ticket.php")); if ($data->expire_time < time()) { $accessToken = $this->getAccessToken(); // 如果是企業號用以下 URL 獲取 ticket // $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken"; $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken"; $res = json_decode($this->httpGet($url)); $ticket = $res->ticket; if ($ticket) { $data->expire_time = time() + 7000; $data->jsapi_ticket = $ticket; $this->set_php_file("jsapi_ticket.php", json_encode($data)); } } else { $ticket = $data->jsapi_ticket; } return $ticket; } private function getAccessToken() { // access_token 應該全域性儲存與更新,以下程式碼以寫入到檔案中做示例 $data = json_decode($this->get_php_file("access_token.php")); if ($data->expire_time < time()) { // 如果是企業號用以下URL獲取access_token // $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret"; $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret"; $res = json_decode($this->httpGet($url)); $access_token = $res->access_token; if ($access_token) { $data->expire_time = time() + 7000; $data->access_token = $access_token; $this->set_php_file("access_token.php", json_encode($data)); } } else { $access_token = $data->access_token; } return $access_token; } private function httpGet($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); // 為保證第三方伺服器與微信伺服器之間資料傳輸的安全性,所有微信介面採用https方式呼叫,必須使用下面2行程式碼開啟ssl安全校驗。 // 如果在部署過程中程式碼在此處驗證失敗,請到 http://curl.haxx.se/ca/cacert.pem 下載新的證書判別檔案。 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } private function get_php_file($filename) { return trim(substr(file_get_contents($filename), 15)); } private function set_php_file($filename, $content) { $fp = fopen($filename, "w"); fwrite($fp, "<?php exit();?>" . $content); fclose($fp); } }
  • 然後我們直接呼叫方法即可
public function getLocation(){
    $jssdk = new Location("your appID", "your appSecret"); //例項化引入檔案的類,並將2個引數傳進去,自己在微信公眾後臺看
    $signPackage = $jssdk->GetSignPackage(); //獲取jsapi_ticket,生成JS-SDK許可權驗證的簽名。
    return view('getLocation',['signPackage'=>signPackage]);
}
  • 然後我再帖下前端的程式碼
script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
  <!--通過config介面注入許可權驗證配置,文件上有詳細的說明-->
  wx.config({
    debug: false,
    appId: '<?php echo $signPackage["appId"];?>',
    timestamp: <?php echo $signPackage["timestamp"];?>,
    nonceStr: '<?php echo $signPackage["nonceStr"];?>',
    signature: '<?php echo $signPackage["signature"];?>',
    jsApiList: [
      // 所有要呼叫的 API 都要加到這個列表中
        'checkJsApi',
                'openLocation',
                'getLocation'
    ]
  });
<!--通過ready介面處理成功驗證--> 
  wx.ready(function () {
    // 在這裡呼叫 API
<!--通過checkJsApi判斷當前客戶端版本是否支援指定獲取地理位置--> 
    wx.checkJsApi({
        jsApiList: [
            'getLocation'
        ],
        success: function (res) {
            // alert(JSON.stringify(res));
            // alert(JSON.stringify(res.checkResult.getLocation));
            if (res.checkResult.getLocation == false) {
                alert('你的微信版本太低,不支援微信JS介面,請升級到最新的微信版本!');
                return;
            }
        }
    });

    <!--使用getLocation介面獲取地理位置座標-->
    wx.getLocation({
    success: function (res) {
        var latitude = res.latitude; // 緯度,浮點數,範圍為90 ~ -90
        var longitude = res.longitude; // 經度,浮點數,範圍為180 ~ -180。
        var speed = res.speed; // 速度,以米/每秒計
        var accuracy = res.accuracy; // 位置精度

        alert('緯度位置:'+latitude+'經度位置:'+longitude);//彈出經緯度,就這樣就獲取到了使用者的位置

    },
    cancel: function (res) {
        alert('使用者拒絕授權獲取地理位置');
    }
    }); 
  });
</script>
</html>
  • 就這樣前端就能獲取到當前微信使用者的地理位置了!
