Google oAuth: redirect_uri_mismatch


Google oAuth: redirect_uri_mismatch

当试图从Google获得oAuth令牌时,我们得到一个"redirect_uri_mismatch"错误:

[client 127.0.0.1:49892] {'n  "error" : "redirect_uri_mismatch"'n}, referer: `http://localhost/oAuth/chess-login.html`

使用了两个文件:chess-login.html和plus.php(下面的代码)。

Google API有以下URI:

http://localhost/oAuth/chess-login.html

谁能指出解决办法?

plus.php:

<?php
    $client_id = "XXX.apps.googleusercontent.com"; //your client id
    $client_secret = "XXX"; //your client secret
    $redirect_uri = "http://localhost/chess-login.html";
    $scope = "https://www.googleapis.com/auth/plus.login"; //google scope to access
    $state = "profile"; //optional
    $access_type = "offline"; //optional - allows for retrieval of refresh_token for offline access
    if(isset($_POST['results'])){
        $_SESSION['accessToken'] = get_oauth2_token($_POST['results']);
    }
    //returns session token for calls to API using oauth 2.0
    function get_oauth2_token($code) {
        global $client_id;
        global $client_secret;
        global $redirect_uri;
        $oauth2token_url = "https://accounts.google.com/o/oauth2/token";
        $clienttoken_post = array(
        "code" => $code,
        "client_id" => $client_id,

        "redirect_uri" => $redirect_uri,
        "grant_type" => "authorization_code"
        );
        $curl = curl_init($oauth2token_url);

        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $clienttoken_post);
        curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $json_response = curl_exec($curl);
        error_log($json_response);
        curl_close($curl);   
        $authObj = json_decode($json_response);
        if (isset($authObj->refresh_token)){
            //refresh token only granted on first authorization for offline access
            //save to db for future use (db saving not included in example)
            global $refreshToken;
            $refreshToken = $authObj->refresh_token;
        }
        $accessToken = $authObj->access_token;
        return $accessToken;
    }
?>

您应该将服务器中的redirect_uri设置为与您在客户端的data-redirecturi="postmessage"相匹配(您的流不需要重定向,因此来自Google API控制台的值不会被使用…)

$clienttoken_post = array(
  "code" => $code,
  "client_id" => $client_id,
  "client_secret" => $client_secret,
  "redirect_uri" => "postmessage",  // <== Change here!
  "grant_type" => "authorization_code"
);
