将成员添加到 MailChimp 列表时出现 400 错误请求

我正在发送一个POST请求以下资源 http://developer.mailchimp.com/documentation/mailchimp/reference/lists/members/并得到 400。我明白错误意味着什么 http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/，但仍然不确定为什么我会得到它GET对同一资源的请求有效。

/lists/{list_id}/members

以下是代码摘录：

$client = new \GuzzleHttp\Client();

$response = $client->request('POST', // <-- Drop in a GET here and it works, other than it's not the behavior I need.
    env('MAILCHIMP_API_URL') . 'lists/' . env('MAILCHIMP_LIST_KEY') . '/members',
    [
        'auth'  => ['app', env('MAILCHIMP_API_KEY')],
        'query' => [
            'email_address' => '[email protected] /cdn-cgi/l/email-protection',
            'email_type'    => 'html',
            'status'        => 'subscribed',
        ]
    ]);

dd($response->getStatusCode());

您正在发送一个POST请求与query参数。您需要发送JSON编码体！

$client = new \GuzzleHttp\Client();

$response = $client->request('POST', // <-- Drop in a GET here and it works, other than it's not the behavior I need.
    env('MAILCHIMP_API_URL') . 'lists/' . env('MAILCHIMP_LIST_KEY') . '/members',
    [
        'auth'  => ['app', env('MAILCHIMP_API_KEY')],
        'json' => [
            'email_address' => '[email protected] /cdn-cgi/l/email-protection',
            'email_type'    => 'html',
            'status'        => 'subscribed',
        ]
    ]);

dd($response->getStatusCode());
