出了什么问题?
这是我的全部代码,我认为应该没问题,但我不知道为什么......使用 Postman 时我没有错误,并且收到了令牌,而使用 Curl 时我收到了此错误。我在本地与 Mamp pro 一起工作。
$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 $token;
string(253) "POST&https%3A%2F%2Faccount.api.here.com%2Foauth2%2Ftoken&grant_type%3Dclient_credentials%26oauth_consumer_key%3D********%26oauth_nonce%3D1468397107%26oauth_signature_method%3DHMAC-SHA256%26oauth_timestamp%3D1605523226%26oauth_version%3D1.0"
在文档中这里我们有这个例子......它看起来是一样的:
POST
&https%3A%2F%2Faccount.api.here.com%2Foauth2%2Ftoken
&grant_type=client_credentials%26oauth_consumer_key%3Daccess-key-id-1234%26oauth_nonce%3DLIIpk4%26
oauth_signature_method%3DHMAC-SHA256%26oauth_timestamp%3D1456945283%26oauth_version%3D1.0
已修复
终于...两天后... 上面的代码有两个错误:
所以改变:
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
与
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
这对我来说很奇怪,因为在curl中我使用http_build_query和GET请求而不是POST,我们可以像数组一样直接使用$data。
并删除:
$params = http_build_query($params, null, ',', PHP_QUERY_RFC3986);
用你漂亮的手写查询,因为 $params 没有双引号。
