如何从 Viva 钱包获取 OAuth 2 访问令牌

Question

在这一步我需要发送这个参数：

 POST https://demo-accounts.vivapayments.com/connect/token HTTP/1.1
 Authorization: Basic Z2VuZXJpY19hY3F1aXJpbmdfY2xpZW50LmFwcHMudml2YXBheW1lbnRzLmNvbTpnZW5lcmljX2FjcXVpcmluZ19jbGllbnQ
 Accept: application/json
 Content-Type: application/x-www-form-urlencoded
 grant_type=client_credentials

我做了什么：（ACCESS_TOKEN我已经得到）

    $ch = curl_init();
    $options = array(
    CURLOPT_URL => 'https://demo-accounts.vivapayments.com/connect/token',
    CURLOPT_POST => 1,
    CURLOPT_HEADER => false,
    CURLOPT_HTTPAUTH => ACCESS_TOKEN,
    CURLOPT_HTTPHEADER => array(
        'Accept: application/json',
        'Content-Type: application/x-www-form-urlencoded',
        'grant_type=client_credentials'
    )
    );

    curl_setopt_array($ch, $options);
    curl_exec($ch);
    curl_close($ch);

我收到的错误：

请求错误您的浏览器发送了该服务器无法理解的请求。参考#7.85c5d3ba.1606074405.4bd39133

Answer 1

CURLOPT_HTTPAUTH

The HTTP authentication method(s) to use. The options are: CURLAUTH_BASIC, CURLAUTH_DIGEST, CURLAUTH_GSSNEGOTIATE, CURLAUTH_NTLM, CURLAUTH_ANY, and CURLAUTH_ANYSAFE.

PHP Manual / cURL

CURLOPT_USERPWD

A username and password formatted as "[username]:[password]" to use for the connection.

PHP Manual / cURL

尝试更新代码以向 /token 端点发送 POST 请求以获取令牌。

您应该在 $result 中找到一个标记：

$credentials = "$login:$password";
$ch = curl_init();
$options = array(
    CURLOPT_URL => 'https://demo-accounts.vivapayments.com/connect/token',
    CURLOPT_POST => 1,
    CURLOPT_HEADER => false,
    // Set the auth type as `Basic`
    CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
    // Set login and password for Basic auth
    CURLOPT_USERPWD => $credentials,
    CURLOPT_HTTPHEADER => array(
        'Accept: application/json',
        'Content-Type: application/x-www-form-urlencoded'
    ),
    // To send additional parameters in the POST body
    CURLOPT_POSTFIELDS => "grant_type=client_credentials"
);

curl_setopt_array($ch, $options);
// This is the response for your request
$result = curl_exec($ch);
// This is the response status code (if you are interested)
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
