微信签名的设置

public function actionStationShare(){
        $appId = "";
        $Secret = "";
        $url = Yii::$app->request->get('url');

最后我来附上一份完整的写好的代码模板

<?php

//curl请求，同时支持get和post
public function actionCurlRequest($url,$data=null){
    $curl = curl_init();
    curl_setopt($curl,CURLOPT_URL,$url);
    curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE);
    curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE);
    if(!empty($data)){
        curl_setopt($curl,CURLOPT_POST,1);
        curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
    }

    curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}

//获取token
public function actionGetToken(){
    //设置url
    $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=填写你的APPID就可以&secret=填写你的secret就可以';
    //发起请求
    $res = json_decode(self::actionCurlRequest($url));
    //加入缓存
    Yii::$app->session['wx_token'] = $res->access_token;
    //返回数据
    return $res->access_token;
}

//获取ticket
function actionGetTicket() {
    if(!empty(Yii::$app->session['wx_token'])){
            $token = Yii::$app->session['wx_token'];
        }else{
            unset(Yii::$app->session['wx_token']);
            $token = self::actionGetToken();
        }
      $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=".$token;
      $res = self::actionCurlRequest($url);
      $res = json_decode($res, true);
      //这里应该把access_token缓存起来，至于要怎么缓存就看各位了，有效期是7200s
      return $res->ticket;
}

//生成随机字符串
private function actionCreateNonceStr($length = 16) {
    $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    $str = "";
    for ($i = 0; $i < $length; $i++) {
      $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
    }
    return $str;
}

//这个接口是最后返回给前端的数据
public function actionStationShare(){
    if(!empty(Yii::$app->session['wx_token'])){
        $token = Yii::$app->session['wx_token'];
    }else{
        unset(Yii::$app->session['wx_token']);
        $token = self::actionGetToken();
    }
    $appId = "";
    $Secret = "";
    $url = Yii::$app->request->get('url');//获取当前的url
    $ticket = self::actionGetTicket();//获取票据
    $timestamp = time();//时间
    $nonceStr = self::actionCreateNonceStr();//随机字符串
    $string = "jsapi_ticket=".$ticket."&noncestr=".$nonceStr."&timestamp=".$timestamp."&url=".$url;
    $signature = sha1($string);
    $signPackage = array(
      "appId"     => $appId,
      "noncestr"  => $nonceStr,
      "timestamp" => $timestamp,
      "url"       => $url,
      "signature" => $signature,
      "rawString" => $string
    );
    return Helper::format_data ( SUCC, $signPackage );
}

 

是不是一下子思路清晰了呢？嘿嘿~
