微信企业号获取用户授权登陆信息

今天做到一个企业号的授权登陆；与公众号授权登陆有稍微区别；

需要用到三个企业号的信息：

agentid：企业应用的id[企业号有 公众号无]

corpid：企业Id[类似公众好的appid]

corpsecret：管理组的凭证密钥[类似公众好的appsecret]

创建文件config.php 里面包含一些常量与自定义函数

<?php
   define('WX_ID','wx011c30b1a3e2AAAA');
   define('WX_SC','bFgmCcaoxF7stnIUXStM3LloMvZUiNieTzd3EVcBBBB');
   define('WX_CODE_URL','https://open.weixin.qq.com/connect/oauth2/authorize?appid=%s&redirect_uri=%s&response_type=code&scope=snsapi_userinfo&agentid=1000002&state=%s#wechat_redirect');
   define('WX_TOKEN_URL','https://qyapi.weixin.qq.com/cgi-bin/user/getuserinfo?access_token=%s&code=%s');
   define('WX_USER_URL','https://qyapi.weixin.qq.com/cgi-bin/user/getuserdetail?access_token=%s');
   define('WX_ACCESS_TOKEN','https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=%s&corpsecret=%s');
   define('WEB_HOST','http://www.a.com/abc');
    
   function getAccessToken($corpid,$secrect) {
		$data = json_decode(file_get_contents("access_token.json"));
		if ($data->expire_time < time()) {
			$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=".$corpid."&corpsecret=".$secrect;
			$res = json_decode(httpGet($url));
			$access_token = $res->access_token;
			if ($access_token) {
			  $data->expire_time = time() + 6000;
			  $data->access_token = $access_token;
			  $fp = fopen("access_token.json", "w");
			  fwrite($fp, json_encode($data));
			  fclose($fp);
			}
		} else {
			$access_token = $data->access_token;
		}
		return $access_token;
	}
	function httpGet($url) {
		$curl = curl_init();
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($curl, CURLOPT_TIMEOUT, 500);
		curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
		curl_setopt($curl, CURLOPT_URL, $url);

		$res = curl_exec($curl);
		curl_close($curl);

		return $res;
	}
	function httpPost($url,$data_string){
		$ch = curl_init($url);
		curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
		curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
		curl_setopt($ch, CURLOPT_HTTPHEADER, array(
		  'Content-Type: application/json',
		  'Content-Length: ' . strlen($data_string))
		);
		$result = curl_exec($ch);
		return $result;
	}
?>

创建入口文件index.php

<?php
	require_once('./config.php');
	$wxid = isset($_COOKIE['wxida'])?$_COOKIE['wxida']:false;
	if(!$wxid){
		if(isset($_GET['code'])){//获取到code
			$token = getAccessToken(WX_ID,WX_SC);//获取toekn
			$tokenUrl = sprintf(WX_TOKEN_URL,$token,$_GET['code']);//组装URL获取user_ticket
			$tokenStr = file_get_contents($tokenUrl);
			$tokenArr = json_decode($tokenStr,true);
			if(isset($tokenArr['user_ticket'])){
				 $userUrl = sprintf(WX_USER_URL,$token);//组装URL获取用户信息
				 $post['user_ticket'] = $tokenArr['user_ticket'];
				 $userStr = httpPost($userUrl, json_encode($post));
				 $userArr = json_decode($userStr,true);
				 if($userArr['errcode']>0){
					  echo '<script>alert("'.$tokenArr['errmsg'].'");window.location.href="./index.php"</script>';
				 }else{
					  $wxid = $userArr['userid'];
					  $wxname = $userArr['name'];
					  $wximg = $userArr['avatar'];
					  setcookie('wxida',$wxid,time()+86400*30);
					  $wxnameB = base64_encode($wxname);
					  $sql = 'insert into weishang_users (id,`wxid`,`wximg`,`wxname`,`creates`) Values(NULL,"'.$wxid.'","'.$wximg.'","'.$wxnameB.'",NOW()) on duplicate key update `wxname`="'.$wxnameB.'"'; 
					  mysql_query($sql);
					  header("Location:".WEB_HOST);
				 }
			}else{//没有获取user_ticket两种情况 1出错2非成员
				if($tokenArr['errcode']>0){
				  echo '<script>alert("'.$tokenArr['errmsg'].'");window.location.href="./index.php"</script>';
				}else{
				  echo "<script>alert('你非企业号成员');WeixinJSBridge.call('closeWindow');</script>";
				}
			}
			exit;
		}else{//跳转进行code获取
         $codeUrl = WX_CODE_URL;
         $codeUrl = sprintf($codeUrl,WX_ID, urlencode(WEB_HOST),'gerinn');
			header("Location:".$codeUrl);
			exit;
		}
	}
?>
