打开流失败: HTTP 请求失败! HTTP/ 1.0 400 坏请求 - OAuth 2. 0 POST
原标题：Failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request - OAuth 2.0 POST
I am working with YouTube APIs for my college project, and I keep getting an error. Here I send them to the authorisation page to log in, when they allow access it sends the $_GET[ code ] string back. Then I send this along with some other data and it should send back a JSON object. Instead I am just getting
Warning: file_get_contents(https://accounts.google.com/o/oauth2/token) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in http://www.example.net/callback.php on line 27
I have replaced my domain with example.net just for security
urlencode($_GET[ code ]),
client_id => urlencode( 111522767640.apps.googleusercontent.com ),
client_secret => urlencode( secret ),
redirect_uri => urlencode( http://example.net/callback.php ),
grant_type => urlencode( authorization_code )
)
);
$params =
array( http =>
array(
method => POST /o/oauth2/token HTTP/1.1 ,
header => Host: accounts.google.com
.
Content-Type: application/x-www-form-urlencoded ,
content => $postdata
)
);
$context = stream_context_create($params);
$result = file_get_contents( https://accounts.google.com/o/oauth2/token , false,$context);
var_dump($_SESSION);
var_dump($result);
}
else //If code isnt set, user must have come here erroniously or has denied access to this program
{
//header( Location: www.example.net/error.php ) ;
}
?>

file_get_contents is going to make a GET request to the url specified, but oauth2/token needs a POST request.
See reference Google OAuth2, PHP HTTP.
if you are using oauth2, goto libraries/oauth2/provider.php and uncomment the code line 182 shows
$ci = get_instance();
$ci->load->spark( curl/1.2.1 );
$ci->curl
->create($url)
->post($params, array( failonerror => false));
$response = $ci->curl->execute();
Here s how to do the Google oAuth properly:
$config = (object) array(
CLIENT_ID => AAAAA ,
CLIENT_SECRET => BBBBB ,
REFRESH_TOKEN => CCCCC ,
);
$sJSON = file_get_contents( https://www.googleapis.com/oauth2/v4/token ,FALSE,
stream_context_create(array( http =>array(
ignore_errors => TRUE, // see errors in response instead of empty on error
method => POST ,
header => array(
Content-Type: application/x-www-form-urlencoded
),
content => http_build_query(array(
grant_type => refresh_token ,
client_id => $config->CLIENT_ID,
client_secret => $config->CLIENT_SECRET,
refresh_token => $config->REFRESH_TOKEN
))
)))
);
You can then use json_decode() to parse $sJSON into an object and then retrieve the access_token property.
For those who are wondering how to get the CLIENT_ID, CLIENT_SECRET, and REFRESH_TOKEN, watch this video. It s not easy. In my case, I needed to do this for Google Adwords API. So, I had to get my Developer Token and Login Customer ID from https://ads.google.com/home/tools/manager-accounts. Then, I had to go to https://console.developers.google.com/apis/credentials with this guide to generate a Client ID and Client Secret. Then, I followed this guide to learn how to get my Refresh Token.
