尝试从Google获取oAuth令牌时，我们收到“ 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具有以下URI：
http://localhost/oAuth/chess-login.html
谁能指出解决方案？
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,
"client_secret" => $client_secret,
"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;
}
?>

参考方案
您应该在服务器中设置redirect_uri使其与客户端中的data-redirecturi="postmessage"相匹配（您的流程不需要重定向，因此不会使用Google API控制台中的值...）
. . .
$clienttoken_post = array(
"code" => $code,
"client_id" => $client_id,
"client_secret" => $client_secret,
"redirect_uri" => "postmessage", // <== Change here!
"grant_type" => "authorization_code"
);
