无法将json生成的动态口令作为短信发送到Swift中的phoneNumber

import MessageUI

func sendSMSWithDynamicToken(token: String, phoneNumber: String) {
    if MFMessageComposeViewController.canSendText() {
        let messageComposeVC = MFMessageComposeViewController()
        messageComposeVC.body = token
        messageComposeVC.recipients = [phoneNumber]
        messageComposeVC.messageComposeDelegate = self
        
        present(messageComposeVC, animated: true, completion: nil)
    } else {
        // 当设备不支持短信功能或者无法发送短信时的处理逻辑
    }
}

// 实现MFMessageComposeViewControllerDelegate代理方法
extension YourViewController: MFMessageComposeViewControllerDelegate {
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        // 处理短信发送结果
        controller.dismiss(animated: true, completion: nil)
    }
}
