我正在尝试编写一个CodeIgniter控制器来处理37signals的Basecamp API的OAuth2身份验证。
问题是我在尝试连接(通过cURL)到https://launchpad.37signals.com/authorization.json时遇到“内部校验和失败”错误,在HTTP标头中提供了Auth Token。
这是我的控制器类的索引和_authcode函数:
<?php
// constants:
// BC_REQUEST_URL = 'https://launchpad.37signals.com/authorization/new'
// BC_TOKEN_URL = 'https://launchpad.37signals.com/authorization/token'
// ...
public function index() {
// if get data is set.
if ($this->input->get()) {
// if auth code is provided via GET, switch to _authcode method.
if ( $code = $this->input->get('code') ) {
return $this->_authcode($code);
}
// On error, kill yourself.
if ( $error = $this->input->get('error') ) {
die($error);
}
}
// redirect to 37 signals to get an authcode
header("Location: ".BC_REQUEST_URL."?type=web_server&client_id=".BC_CLIENT_ID."&redirect_uri=".BC_REDIRECT_URL."");
}
// handles the Authentication code that is returned by 37 Signals.
private function _authcode($code) {
// set vars to POST
$vars = array(
'type' => 'web_server',
'client_id' => BC_CLIENT_ID,
'redirect_uri' => BC_REDIRECT_URL,
'client_secret' => BC_CLIENT_SECRET,
'code' => $code
);
// make a request for the access_token
$url = BC_TOKEN_URL;
$c = curl_init($url);
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS, http_build_query($vars));
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$response = json_decode(curl_exec($c));
curl_close($c);
unset($c,$url);
// get the access vars from this request
$expiry_seconds = $response->expires_in; // default: 1209600 (14 days)
$refresh_token = $response->refresh_token;
$access_token = $response->access_token;
unset($response);
// make a separate request to get user info for current user.
$url = "https://launchpad.37signals.com/authorization.json";
$c = curl_init($url);
curl_setopt($c, CURLOPT_HTTPHEADER, array(
"Authorization: Bearer <$access_token>",
"Content-Type: application/json; charset=utf-8",
"User-Agent: MyApp (http://myapp.example.com)"
));
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$response = json_decode(curl_exec($c)); // reply from 37 signal auth
curl_close($c);
unset($c,$url);
echo "response obj = " . print_r($response,1);
/* prints: response obj = stdClass Object ( [error] => OAuth token could not be verified. The internal checksum failed, so the token data was somehow mangled or tampered with. ) */
// get the user data from this request
// $expires_at = $response->expires_at; // the timestamp for when this request expires
// $identity = $response->identity; // the current user
// $accounts = $response->accounts; // list of accounts we can access
// unset($response);
// store the response data to the database for easy recall.
// $this->db->query("REPLACE INTO `sometable` SET `key1`='value', `key2`='value');
}
// ...
?>

使用varchar(255)在数据库中保存身份验证令牌时遇到此错误。 Basecamp的auth令牌有一些校验和数据,它使令牌超过255个字符。
你似乎没有在你的例子中从数据库中提取它,所以这可能不会影响你,但是检查Basecamp的令牌被切断是我首先要看的。
可选择删除&lt;&gt;设置Bearer标头时$ access_token周围的字符。
