增加ThinkSDK的微信第三方登录
1、配置文件增加相应参数
//支付宝登录
'THINK_SDK_WEIXIN' => array(
'APP_KEY' => '', //应用注册成功后分配的 APP ID
'APP_SECRET' => '', //应用注册成功后分配的KEY
'CALLBACK' => URL_CALLBACK . 'weixin',
),2、WeixinSDK代码<?php
class WeixinSDK extends ThinkOauth
{
/**
* 获取requestCode的api接口
* @var string
*/
protected $GetRequestCodeURL = 'https://open.weixin.qq.com/connect/qrconnect';
/**
* 获取access_token的api接口
* @var string
*/
protected $GetAccessTokenURL = 'https://api.weixin.qq.com/sns/oauth2/access_token';
/**
* API根路径
* @var string
*/
protected $ApiBase = 'https://api.weixin.qq.com/';
public function getRequestCodeURL()
{
$this->config();
$params = array(
'appid' => $this->AppKey,
'redirect_uri'=>$this->Callback,
'response_type'=>'code',
'scope'=>'snsapi_login'
);
return $this->GetRequestCodeURL . '?' . http_build_query($params);
}
/**
* 获取access_token
* @param string $code 上一步请求到的code
*/
public function getAccessToken($code, $extend = null){
$this->config();
$params = array(
'appid' => $this->AppKey,
'secret' => $this->AppSecret,
'grant_type' => $this->GrantType,
'code' => $code,
);
$data = $this->http($this->GetAccessTokenURL, $params, 'POST');
$this->Token = $this->parseToken($data, $extend);
return $this->Token;
}
/**
* 组装接口调用参数 并调用接口
* @param string $api 微博API
* @param string $param 调用API的额外参数
* @param string $method HTTP请求方法 默认为GET
* @return json
*/
public function call($api, $param = '', $method = 'GET', $multi = false){
/* 腾讯微博调用公共参数 */
$params = array(
'access_token' => $this->Token['access_token'],
'openid' => $this->openid(),
);
$vars = $this->param($params, $param);
$data = $this->http($this->url($api), $vars, $method, array(), $multi);
return json_decode($data, true);
}
/**
* 解析access_token方法请求后的返回值
*/
protected function parseToken($result, $extend)
{
$data = json_decode($result,true);
//parse_str($result, $data);
if($data['access_token'] && $data['expires_in']){
$this->Token = $data;
$data['openid'] = $this->openid();
return $data;
} else
throw new Exception("获取微信 ACCESS_TOKEN 出错：{$result}");
}
/**
* 获取当前授权应用的openid
*/
public function openid()
{
$data = $this->Token;
if(!empty($data['openid']))
return $data['openid'];
else
exit('没有获取到微信用户ID！');
}
}
?>3、获取信息的接口 //登录成功，微信用户信息
public function weixin($token){
$weixin = \ThinkOauth::getInstance('weixin', $token);
$data = $weixin->call('sns/userinfo');
if($data['ret'] == 0){
$userInfo['type'] = 'WEIXIN';
$userInfo['name'] = $data['nickname'];
$userInfo['nick'] = $data['nickname'];
$userInfo['head'] = $data['headimgurl'];
return $userInfo;
} else {
throw_exception("获取微信用户信息失败：{$data['errmsg']}");
}
