最近開發(fā)微信，涉及到微信用戶登錄的問題，研究了一下還是搞定了，整理了一下跟大家貼出來我寫的這個代碼吧，需要用的東西我都已經(jīng)定義成常量，需要的話直接修改，以下是代碼：
<?php
namespace Apps\Controller;
use Common\Controller\AppBaseController;
define("TOKEN", "");//你微信定義的token
define("APPID", "");//你微信定義的appid
define("APPSECRET","");//你微信公眾號的appsecret
class TestController extends AppBaseController //繼承的這個控制器沒用 你可以繼承其他的任意一個
{
//第一步：用戶同意授權，獲取code
function accept(){
//這個鏈接是獲取code的鏈接 鏈接會帶上code參數(shù)
$REDIRECT_URI = "http://www.yourdomain.com/wxt_webhome/index.php/Apps/Test/getCode";
echo $REDIRECT_URI."<br>";
$REDIRECT_URI = urlencode($REDIRECT_URI);
echo $REDIRECT_URI."<br>";
$scope = "snsapi_userinfo";
echo $scope."<br>";
$state = md5(mktime());
echo $state."<br>";
$url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=".APPID."&redirect_uri=".$REDIRECT_URI."&response_type=code&scope=".$scope."&state=".$state."#wechat_redirect";
header("location:$url");
}
//用戶同意之后就獲取code 通過獲取code可以獲取一切東西了 機智如我
function getCode(){
//獲取accse_token
$code = I("code");
//echo $code;
//echo "<br>";
//用code獲取access_yoken
$url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".APPID."&secret=".APPSECRET."&code=".$code."&grant_type=authorization_code";
//這里可以獲取全部的東西 access_token openid scope
$res = $this->https_request($url);
$res = json_decode($res,true);
$openid = $res["openid"];
echo "<pre>";
//print_r($res);
//echo $openid;
//echo "<br>";
$access_token = $res["access_token"];
//echo $access_token;
//這里是獲取用戶信息
$url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN";
$res = $this->https_request($url);
$res = json_decode($res,true);
//寫入session
print_r($res);
//把用戶的信息寫入session 以備查用
$weixn = $res["openid"];
$nickname = $res["nickname"];
session('weixin',$weixin);
header("location:http://www.yourdomain.com/wxt_webhome/test.php");
}
function https_request($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;
}
}//classend
