微信sdk实现禁止微信分享(使用原生php实现)

在此之前我们已经学习过微信的sdk使用,但是之前实在easyWechat的php插件基础上实现的,具体可以参考:https://www.wj0511.com/site/detail.html?id=331

这里我们来使用原生的php实现微信的sdk-禁止微信分享

一:引入所需要的js


二:通过config接口注入权限验证配置

wx.config({
  debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。
  appId: '', // 必填,公众号的唯一标识
  timestamp: , // 必填,生成签名的时间戳
  nonceStr: '', // 必填,生成签名的随机串
  signature: '',// 必填,签名
  jsApiList: [] // 必填,需要使用的JS接口列表
});

签名的生成步骤如下:

1:获取微信公众号的全局唯一接口调用凭据access_token

调取下面的接口获取access_token

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

get参数说明:

appid:微信公众号的唯一标识appId

secret:微信公众号的appsecret

根据上面的接口可以获取到微信公众号的全局唯一接口调用凭据access_token,接口返回结果如下:

{"access_token":"ACCESS_TOKEN","expires_in":7200}

2:根据access_token获取jsapi_ticket

调取下面的接口获取jsapi_ticket

https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=ACCESS_TOKEN&type=jsapi

get参数说明:

access_token:上面接口获取到的access_token

type:类型,这里指定填jsapi

根据上面的接口可以获取到jsapi_ticket,接口返回结果如下:

{
  "errcode":0,
  "errmsg":"ok",
  "ticket":"bxLdikRXVbTPdHSM05e5u5sUoXNKd8-41ZO3MhKoyN5OfkWITDGgnr2fwJ0m9E8NYzWKVZvdVtaUgWvsdshFKA",
  "expires_in":7200
}

3:根据获取到的jsapi_ticket和noncestr,timestamp,url生成签名

对所有待签名参数按照字段名的ASCII 码从小到大排序后,使用URL键值对的格式(即key1=value1&key2=value2…)拼接成字符串,然后通过sha1加密生成签名

三:通过ready接口处理成功验证后在ready内写我们所需要的微信sdk接口

wx.ready(function(){
  // config信息验证后会执行ready方法,所有接口调用都必须在config接口获得结果之后,config是一个客户端的异步操作,所以如果需要在页面加载时就调用相关接口,则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口,则可以直接调用,不需要放在ready函数中。
});

四:具体实现

根据如上说明,这里我们就以禁止微信分享sdk为例实现:

1:php端:

public function actionTicket()
{
    //开启session
    session_start();
    //appId
    $appId = 'wx73d0c47a64aa5315';
    //secret
    $appSecret = 'aba2793c10623350f6aeee5a728099d3';
    if (!isset($_SESSION['ticket'])){
        //获取微信公众号全局唯一接口调用凭据access_token
        $result = $this->getAccessToken($appId, $appSecret);
        $accessToken = $result['access_token'];
        //获取jsapi_ticket
        $getTicket = $this->getTicket($accessToken);
        $ticket = $getTicket['ticket'];
        $_SESSION['ticket'] = $ticket;
    }
    //jsapi_ticket(公众号用于调用微信JS接口的临时票据)
    $ticket = $_SESSION['ticket'];
    //当前时间戳
    $timestamp = time();
    //随机字符串
    $noncestr = $this->getRandCode();
    //当前url
    $url = $this->getUrl();
    $params = [
        'jsapi_ticket' => $ticket,
        'timestamp' => $timestamp,
        'noncestr' => $noncestr,
        'url' => $url,
    ];
    $options = $this->urlParams($params);
    //获取签名
    $signature = sha1($options);
    //将appId,timestamp,noncestr,signature渲染到页面
    return $this->render('ticket', [
        'appId' => $appId,
        'timestamp' => $timestamp,
        'noncestr' => $noncestr,
        'signature' => $signature,
    ]);
}
/*
 * 获取jsapi_ticket
 */
public function getTicket($accessToken)
{
    $params = [
        'access_token' => $accessToken,
        'type' => 'jsapi',
    ];
    $urlParams = $this->urlParams($params);
    $ticketUrl = 'https://api.weixin.qq.com/cgi-bin/ticket/getticket?' . $urlParams;
    $result = $this->http_curl($ticketUrl);
    return json_decode($result, true);
}
/*
 * 获取微信公众号的全局唯一接口调用凭据access_token
 */
public function getAccessToken($appId, $appSecret)
{
    $params = [
        'grant_type' => 'client_credential',
        'appid' => $appId,
        'secret' => $appSecret,
    ];
    $urlParams = $this->urlParams($params);
    $accessUrl = 'https://api.weixin.qq.com/cgi-bin/token?' . $urlParams;
    $result = $this->http_curl($accessUrl);
    return json_decode($result, true);
}
/*
 * 获取随机码
 */
function getRandCode($num = 16){
    $array = array(
        'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
        'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','v','z',
        '1','2','3','4','5','6','7','8','9','0',
    );
    $tmpstr='';
    $max = count($array);
    for($i=1; $i<=$num; $i++){
        $key = rand(0,$max-1); //'A' -> $array[0]
        $tmpstr .= $array[$key];
    }
    return $tmpstr;
}
/*
 * curl接口调用
 */
public function http_curl($url, $data=null) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($curl);
    curl_close($curl);
    return $result;
}
/*
 * 字符串拼接
 */
public function urlParams($params)
{
    ksort($params);
    reset($params);
    $options = '';
    foreach ($params as $key => $value) {
        $options .= $key . '=' . $value .'&';
    }
    $options = rtrim($options, '&');
    return $options;
}
/*
 * 获取当前url
 */
public function getUrl()
{
    //获取协议类型
    $protocalPort = isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443' ? 'https://' : 'http://';
    //获取当前执行脚本的url
    $phpSelf = $_SERVER['PHP_SELF'] ? $_SERVER['PHP_SELF'] : $_SERVER['SCRIPT_NAME'];
    $pathInfo = isset($_SERVER['PATH_INFO']) ? $_SERVER['PATH_INFO'] : '';
    $queryString = isset($_SERVER['QUERY_STRING']) ? $_SERVER['QUERY_STRING'] : '';
    $relateUrl = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : $phpSelf . (!empty($queryString) ? '?' . $queryString : $pathInfo);
    $url = $protocalPort . (isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : '') . $relateUrl;
    return $url;
}
