爲了不你們少走彎路，這裏先介紹下硬性條件
一、必須是經過認證的微信服務號或者微信企業號才具備此功能。
二、有本身的雲虛擬主機，也就是本身的網站。
開始配置：php

1、公衆號號的設置
一、進入微信公衆平臺後臺，在公衆號設置->功能設置界面下配置好JS接口安全域名，以下圖
html

二、在基本配置裏面完成IP白名單和服務器的配置，這步很重要，以下圖
json

2、網站代碼結構以下api

weixin--|
        |---access_token.php
        |---airkiss.php                        //公衆號連接到該文件
        |---jsapi_ticket.php
        |---jssdk.php
        |---MP_verify_yfiF3OWtLI4GfhBg.txt    //JS接口驗證文件,在設置JS接口時下載後放到網站的，名稱隨機

3、代碼詳情
一、access_token.php安全

<?php exit();?>
{"access_token":"","expire_time":0}

二、airkiss.php服務器

<?php
require_once "jssdk.php";
$jssdk = new JSSDK("yourAppID", "yourAppSecret");//這裏改爲本身的
$signPackage = $jssdk->GetSignPackage();
?>
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title></title>
</head>
<body>

</body>
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
    wx.config({
    beta:true,//開啓內測接口調用，注入wx.invoke方法
    debug:false,//關閉調試模式
    appId: '<?php echo $signPackage["appId"];?>',//AppID
    timestamp: <?php echo $signPackage["timestamp"];?>,//時間戳
    nonceStr: '<?php echo $signPackage["nonceStr"];?>',//隨機串
    signature: '<?php echo $signPackage["signature"];?>',//簽名
    jsApiList: [
      // 全部要調用的 API 都要加到這個列表中
      'configWXDeviceWiFi'
    ]
  });
  wx.ready(function () {
    // 在這裏調用 API
    wx.invoke('configWXDeviceWiFi');
  });
  wx.error(function(res){
      alert("配置出錯");
  });
</script>
</html>

三、jsapi_ticket.php微信

<?php exit();?>
{"jsapi_ticket":"","expire_time":0}

四、jssdk.phpapp

<?php
class JSSDK {
  private $appId;
  private $appSecret;

  public function __construct($appId, $appSecret) {
    $this->appId = $appId;
    $this->appSecret = $appSecret;
  }

  public function getSignPackage() {
    $jsapiTicket = $this->getJsApiTicket();

    // 注意 URL 必定要動態獲取，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();

    // 這裏參數的順序要按照 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 應該全局存儲與更新，如下代碼以寫入到文件中作示例
    $data = json_decode($this->get_php_file("jsapi_ticket.php"));
    if ($data->expire_time < time()) {
      $accessToken = $this->getAccessToken();
      // 若是是企業號用如下 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 應該全局存儲與更新，如下代碼以寫入到文件中作示例
    $data = json_decode($this->get_php_file("access_token.php"));
    if ($data->expire_time < time()) {
      // 若是是企業號用如下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($curl, CURLOPT_TIMEOUT, 500);
    // 爲保證第三方服務器與微信服務器之間數據傳輸的安全性，全部微信接口採用https方式調用，必須使用下面2行代碼打開ssl安全校驗。
    // 若是在部署過程當中代碼在此處驗證失敗，請到 http://curl.haxx.se/ca/cacert.pem 下載新的證書判別文件。
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($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);
  }
}

調通後，就能夠出現下面的這個界面了
