我正在使用他们的 MailchimpMarketing\ApiClient() composer 资源向网站添加一个基本的 Mailchimp 订阅表单。添加用户似乎工作正常，但是当尝试添加已经存在的人时，我希望只有一个很好的 json 响应，以便我可以捕获该错误并将其显示给用户，但我得到以下 GuzzleHttp\Exception \客户端异常：

Client error: `POST https://us10.api.mailchimp.com/3.0/lists/xxxxxxxxxx/members` resulted in a `400 Bad Request` response:
{"type":"http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/","title":"Member Exists","status" (truncated...)

该文档似乎并没有真正解释太多，我也必须找到正确的方法来从堆栈溢出中捕获该错误，因为 Mailchimps 文档是......缺乏！这是代码：

try {
    $response = $mailchimp->lists->addListMember($this->settings_helper->get('mailchimp_list_id'), [
        "email_address" => $form->get_field_value('email'),
        "status" => "subscribed",
        "merge_fields" => [
            "FNAME" => $first_name,
            "LNAME" => $last_name
         ]
    ]);
    
    if ($response->getId()) {
        $this->add_json_success($this->settings_helper->get('mailchimp_success_message'));
    }
} catch (MailchimpMarketing\ApiException $e) {
    $errors[] = $e->getMessage();
} catch (ClientErrorResponseException $e) {
    $errors[] = $e->getMessage();
} catch (GuzzleHttp\Exception\ClientException $e) {
    $errors[] = $e->getMessage();
} …
