[英]Creta Signature for Oauth 1.0 with Curl and Php - Fixing error "Unsupported signature method in the header. Require HMAC-SHA256"
怎么了?
這是我的所有代碼,我認為它應該沒問題,但我不知道為什么......使用郵遞員我沒有錯誤並且我收到令牌而使用 Curl 我收到這個錯誤。 我在當地與 Mamp pro 合作。
$url = "https://account.api.here.com/oauth2/token";
$data = array(
"grant_type" => "client_credentials"
);
$oauthNonce = mt_rand();
$oauthTimestamp = time();
$oauthCustomereKey = "******";
$oauthSignatureMethod = "HMAC-SHA256";
$httpMethod = "POST";
$oauthVersion = "1.0";
$keySecret = "*****";
$baseString = $httpMethod."&". urlencode($url);
$paramString =
"grant_type=client_credentials&".
"oauth_consumer_key=". urlencode($oauthCustomereKey).
"&oauth_nonce=". urlencode($oauthNonce).
"&oauth_signature_method=". urlencode($oauthSignatureMethod).
"&oauth_timestamp=". urlencode($oauthTimestamp).
"&oauth_version=". urlencode($oauthVersion)
;
$baseString = $baseString . "&" . urlencode($paramString);
var_dump($baseString);
$signingKey= urlencode($keySecret) . "&";
$signature = urlencode(
base64_encode(
hash_hmac(
'sha256',
$baseString,
$signingKey,
true
)
)
);
$params = [
"oauth_consumer_key" => $oauthCustomereKey,
"oauth_nonce" => $oauthNonce,
"oauth_signature_method" => $oauthSignatureMethod,
"oauth_timestamp" => $oauthTimestamp,
"oauth_version" => $oauthVersion,
"oauth_signature" => $signature
];
// $lol = 'oauth_consumer_key="' . $oauthCustomereKey . '",oauth_signature_method="'.$oauthSignatureMethod . '",oauth_timestamp="'.$oauthTimestamp.'",oauth_nonce="'.$oauthNonce.'",oauth_version="'.$oauthVersion.'",oauth_signature="'.$signature.'"';
/* This will give you the proper encoded string to include in your Authorization header */
$params = http_build_query($params, null, ',', PHP_QUERY_RFC3986);
$authorization = "Authorization: OAuth " . $params;
var_dump($authorization);
if(!$curl = curl_init()){
exit;
}
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
"Content-Type : application/x-www-form-urlencoded",
$authorization));
$token = curl_exec($curl);
curl_close($curl);
return $token;
string(253) "POST&https%3A%2F%2Faccount.api.here.com%2Foauth2%2Ftoken&grant_type%3Dclient_credentials%26oauth_consumer_key%3D********%26oauth_nonce%3D1468397107%26oauth_signature_method%3DHMAC-SHA256%26oauth_timestamp%3D1605523226%26oauth_version%3D1.0"
POST
&https%3A%2F%2Faccount.api.here.com%2Foauth2%2Ftoken
&grant_type=client_credentials%26oauth_consumer_key%3Daccess-key-id-1234%26oauth_nonce%3DLIIpk4%26
oauth_signature_method%3DHMAC-SHA256%26oauth_timestamp%3D1456945283%26oauth_version%3D1.0
固定的
最后...... 2天后......上面的代碼有2個錯誤:
所以改變:
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
和
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
這對我來說很奇怪,因為使用 curl 我使用 http_build_query 和 GET 請求而不是 POST,我們可以像數組一樣直接使用 $data。
並刪除:
$params = http_build_query($params, null, ',', PHP_QUERY_RFC3986);
並用您的美麗手編寫查詢,因為 $params 沒有雙引號。
