【问题描述】：

我用过这个 api curl -X POST
https://tracking.api.here.com/v2/token -H '授权：承载 {signedRequest}'

我的php代码是

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://tracking.api.here.com/v2/timestamp');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);

if (curl_errno($ch)) {

echo 'Error:' . curl_error($ch);

}

$result = json_decode($result);

curl_close($ch);

$timestamp = ($result->timestamp);

$accessKey = $deviceId;

$secret = $deviceSecret;

$url = "https://account.api.here.com/oauth2/token";

$nonce = mt_rand(100000,999999);

$timestamp = $timestamp;

$baseString = "grant_type=client_credentials&oauth_consumer_key=".$accessKey."&oauth_nonce=".$nonce."&oauth_signature_method=HMAC-SHA256&oauth_timestamp=".$timestamp."&oauth_version=1.0";

$workingString = 数组();

foreach (explode('&', $baseString) as $parameter) {

$parameter = explode('=', $parameter);

$workingString[] = urlencode($parameter[0]).'='.trim(urlencode($parameter[1]));

}

$urlEncodeParamaterString = implode('&', $workingString);

$fullBaseString = "POST&".urlencode($url)."&".urlencode($urlEncodeParamaterString); $hashKey = $secret.'&';

函数编码($data) {

return str_replace(['+', '/'], ['-', '_'], base64_encode($data));

}

函数解码($data) {

return base64_decode(str_replace(['-', '_'], ['+', '/'], $data));

}

$binaryKey = 解码($hashKey);

$signature = encode(hash_hmac("sha256", $fullBaseString, $binaryKey, true));

$authHeader = "OAuth oauth_consumer_key=".$accessKey.",oauth_signature_method='HMAC-SHA256',oauth_timestamp='".$timestamp."',oauth_nonce=".$nonce.",oauth_version='1.0' ,oauth_signature=".$signature."";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://tracking.api.here.com/v2/token');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POST, 1);

$headers = 数组();

$headers[] = 'Content-Type: application/x-www-form-urlencoded';

$headers[] = '授权：'.$authHeader;

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);

if (curl_errno($ch)) {

echo 'Error:' . curl_error($ch);

}

curl_close($ch);

回声''; print_r($result);

输出 { 代码：401， id: "312f56e5-db4f-40f5-807f-c5a0413dd668", 消息：“未找到给定 deviceId 的许可证。”, error: "Timestamp wrong 当请求时间戳与服务器时间相差超过 10 秒时，将带有当前服务器时间戳的 x-here-timestamp 标头添加到响应中。不正确的签名如果 OAuth 签名不正确，则响应将是 401 但没有 x-here-timestamp 字段。" }
