在PHP SDK中使用JWT获取Docusign API访问令牌的步骤如下:
composer require firebase/php-jwt
use Firebase\JWT\JWT;
function generateJwtToken($expirationTime, $otherParams) {
$privateKey = 'your_private_key';
$issuer = 'your_issuer';
$clientId = 'your_client_id';
$payload = [
'iss' => $issuer,
'sub' => $clientId,
'aud' => 'account-d.docusign.com',
'exp' => $expirationTime,
'iat' => time()
];
return JWT::encode($payload, $privateKey, 'RS256');
}
function getAccessToken($jwtToken, $otherParams) {
$url = 'https://account-d.docusign.com/oauth/token';
$clientId = 'your_client_id';
$clientSecret = 'your_client_secret';
$postData = [
'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
'assertion' => $jwtToken,
'client_id' => $clientId,
'client_secret' => $clientSecret
];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($httpCode === 200) {
$responseData = json_decode($response, true);
return $responseData['access_token'];
} else {
return false;
}
}
请注意,在上述代码示例中,需要替换相应的配置参数,如API密钥、秘钥、客户端ID等。此外,需要根据实际情况处理错误和异常情况。
希望这些步骤能帮助你在PHP SDK中使用JWT获取Docusign API访问令牌。
