对接Line登录

【前提-需要FQ走香港线路比如下载云梯】

 

1.申请开发者账号：

    获取client_id 和 client_secret,并设置回调url--建议设置在香港服务器，通过其中转，就可以跳过每台服务器都要香港IP

 2.前端页面加LINE按钮测试,获取code
按钮链接如下:

<a href="https://access.line.me/oauth2/v2.1/authorize?response_type=code&client_id=xxxxx&redirect_uri=https://xxxxx&state=200&scope=openid%20profile" target="_blank" title="访问示例网站">LINE登录</a>

当点击改按钮时，会自动跳转到LINE登录界面，上面URL会出现code和state

3.获取token

public function getAccessToken($code):string
{
    $url = 'https://api.line.me/oauth2/v2.1/token';
    $header = [
        'Content-type:application/x-www-form-urlencoded'
    ];
    $redirect_uri = str_replace('\r','',$this->redirect_uri);
    $redirect_uri = str_replace('\n','',$redirect_uri);
    $post_data = [
        'grant_type' => 'authorization_code',
        'code' => $code,
        'client_id' => $this->app_id,
        'client_secret' => $this->app_secret,
        'redirect_uri' => $redirect_uri
    ];
    Log::info('请求url===='.$url);
    Log::info('请求参数===='.json_encode($post_data,JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES));
    $res = $this->http_post($url,$post_data,$header);
    Log::info('请求结果===='.$res);
    if(!$res){
        throwError('line获取access_token请求失败');
    }
    //dd($res);
    $res = json_decode($res,true);
    if(!empty($res['error'])){
        throwError($res['error_description']);
    }
    return $res['access_token'];
}

4.获取LIne用户信息

/**获取用户信息
 * @return array
 */
public function getUserInfo($code):array
{
    $access_token = $this->getAccessToken($code);
    $url = 'https://api.line.me/v2/profile';
    $header = [
        'Content-type:application/x-www-form-urlencoded'
    ];
    $post_data = [
        'access_token' => $access_token
    ];
    Log::info('请求url===='.$url);
    Log::info('请求参数===='.json_encode($post_data,JSON_UNESCAPED_UNICODE));
    $res = $this->http_post($url,$post_data,$header);
    Log::info('请求结果===='.$res);
    if(!$res){
        throwError('line获取用户信息请求失败');
    }
    //dd($res);
    return json_decode($res,true);
}

备注：

http_post方法：

private function http_post($sUrl, $aData, $aHeader)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $sUrl);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($aData));
    $sResult = curl_exec($ch);
    if ($sError = curl_error($ch)) {
        die($sError);
    }
    curl_close($ch);
    return $sResult;
}
