使用curl的php中的OAuth 2.0

我需要获取OAuth 2.0的access_token和refresh_token才能访问Google API,以下php脚本应返回一个带有access_token,refresh_token的json,如下所示：

{
  "access_token" : "####",
  "token_type" : "Bearer",
  "expires_in" : 3600,
  "refresh_token" : "####"
}

但是,PHP脚本仅向我返回此错误消息：

{
"error" : "invalid_request",
"error_description" : "Client must specify either client_id or client_assertion, not both"
}

我试图删除client_secret / client_id并仅使用client_id / client_secret,但仍然遇到相同的错误.

PHP脚本

$client_id = '###.apps.googleusercontent.com';
$redirect_uri = 'http://localhost/phpConnectToDB/csv/refreshFusionTable.php';
$client_secret = '###';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://accounts.google.com/o/oauth2/token");

$code = $_REQUEST['code'];

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);


curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'code' => $code,
'client_id' => $clientID,
'client_secret' => $clientSecret,
'redirect_uri' => $redirect_uri,
'grant_type' => 'authorization_code'
));

$data = curl_exec($ch);

var_dump($data);

虽然cmd中的curl可以正常工作,并且可以返回我访问和刷新令牌,但没有任何错误.

curl --data "code=###&client_id=###.apps.googleusercontent.com&client_secret=###&redirect_uri=http://localhost/phpConnectToDB/csv/refreshFusionTable.php&grant_type=authorization_code" https://accounts.google.com/o/oauth2/token

尽管.php脚本存在并且位于给定的路径上,但我不明白为什么会收到丢失的方案错误.请问你能帮帮我吗 ？

EDIT问题,“ redirect_uri的参数值无效：缺少方案”已解决,我只替换了’redirect_uri’=> urlencode($redirect_uri),带有此“ redirect_uri” => $redirect_uri,在CURLOPT_POSTFIELDS中.

解决方法:

哇,愚蠢的错误,我应该休息一下.

变量名称不匹配.
我定义了：

$client_id = '###.apps.googleusercontent.com';
$client_secret = '###';

但是这里我使用了不存在的clientID clientSecret

curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'code' => $code,
'client_id' => $clientID,
'client_secret' => $clientSecret,
'redirect_uri' => $redirect_uri,
'grant_type' => 'authorization_code'
));

固定且有效的PHP脚本

$client_id = '###.apps.googleusercontent.com';
$redirect_uri = 'http://localhost/phpConnectToDB/csv/refreshFusionTable.php';
$client_secret = '###';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://accounts.google.com/o/oauth2/token");

curl_setopt($ch, CURLOPT_POST, TRUE);

$code = $_REQUEST['code'];

// This option is set to TRUE so that the response
// doesnot get printed and is stored directly in
// the variable
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_POSTFIELDS, array(
'code' => $code,
'client_id' => $client_id,
'client_secret' => $client_secret,
'redirect_uri' => $redirect_uri,
'grant_type' => 'authorization_code'
));

$data = curl_exec($ch);

var_dump($data);

但是我不得不说,谷歌在这里提供了一些误导性的错误消息,因为我没有定义client_id和client_secret,错误消息是：

{
"error" : "invalid_request",
"error_description" : "Client must specify either client_id or client_assertion, not both"
}
