PHP调用微博接口实现微博登录的方法示例

在平时项目开发过程中,除了注册本网站账号进行登录之外,还可以调用第三方接口进行登录网站。这里以微博登录为例。微博登录包括身份认证、用户关系以及内容传播。允许用户使用微博帐号登录访问第三方网站,分享内容,同步信息。

1、首先需要引导需要授权的用户到如下地址:

https://api.weibo.com/oauth2/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI

如果用户同意授权,页面跳转至 YOUR_REGISTERED_REDIRECT_URI/?code=CODE:

2、接下来要根据上面得到的code来换取Access Token:

https://api.weibo.com/oauth2/access_token?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=authorization_code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI&code=CODE

返回值:

JSON

{
 "access_token": "SlAV32hkKG",
 "remind_in": 3600,
 "expires_in": 3600 
}

3、最后,使用获得的OAuth2.0 Access Token调用API,获取用户身份,完成用户的登录。

为了方便,我们先将get和post封装到application下的common.php中:
应用公共文件common.php:

function get( $url, $_header = NULL )
{
    $curl = curl_init();
    //curl_setopt ( $curl, CURLOPT_SAFE_UPLOAD, false); 
    if( stripos($url, 'https://') !==FALSE )
    {
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    }

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    if ( $_header != NULL )
    {
        curl_setopt($curl, CURLOPT_HTTPHEADER, $_header);
    }
    $ret    = curl_exec($curl);
    $info    = curl_getinfo($curl);
    curl_close($curl);

    if( intval( $info["http_code"] ) == 200 )
    {
        return $ret;
    }

    return false;
}
/*
 * post method
 */
function post( $url, $param )
{
     $oCurl = curl_init ();
    curl_setopt ( $oCurl, CURLOPT_SAFE_UPLOAD, false);
    if (stripos ( $url, "https://" ) !== FALSE) {
        curl_setopt ( $oCurl, CURLOPT_SSL_VERIFYPEER, FALSE );
        curl_setopt ( $oCurl, CURLOPT_SSL_VERIFYHOST, false );
    }

    curl_setopt ( $oCurl, CURLOPT_URL, $url );
    curl_setopt ( $oCurl, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $oCurl, CURLOPT_POST, true );
    curl_setopt ( $oCurl, CURLOPT_POSTFIELDS, $param );
    $sContent = curl_exec ( $oCurl );
    $aStatus = curl_getinfo ( $oCurl );
    curl_close ( $oCurl );
    if (intval ( $aStatus ["http_code"] ) == 200) {
        return $sContent;
    } else {
        return false;
    }
}
控制器处理代码Login.php:

class Login extends \think\Controller 
{
    public function index()
    {
        $key = "****";
        $redirect_uri = "***微博应用安全域名***/?backurl=***项目本地域名***/home/login/webLogin?";
        //授权后将页面重定向到本地项目
        $redirect_uri = urlencode($redirect_uri);
        $wb_url = "https://api.weibo.com/oauth2/authorize?client_id={$key}&response_type=code&redirect_uri={$redirect_uri}";
        $this -> assign('wb_url',$wb_url);
        return view('login');
    }


    public function webLogin(){
        $key = "*****";
        //接收code值
        $code = input('get.code');
        //换取Access Token: post方式请求    替换参数: client_id, client_secret,redirect_uri, code
        $secret = "********";
        $redirect_uri = "********";
        $url = "https://api.weibo.com/oauth2/access_token?client_id={$key}&client_secret={$secret}&grant_type=authorization_code&redirect_uri={$redirect_uri}&code={$code}";
        $token = post($url, array());
        $token = json_decode($token, true);
        //获取用户信息 : get方法,替换参数: access_token, uid
        $url = "https://api.weibo.com/2/users/show.json?access_token={$token['access_token']}&uid={$token['uid']}";
        $info = get($url);
        if($info){
            echo "<p>登录成功</p>";
        }
    }
}

模板代码login.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>微博登录</title>
</head>
<body>
<a href="{$wb_url}">点击这里进行微博登录</a>
</body>
</html>

效果图:
