经过大量的斗争，我设法处理它，所以我在这里张贴的解决方案，以防其他人需要同样的解决方案：）
首先，我在过滤器woocommerce_payment_successful_result中捕获了stripe客户ID和支付令牌。

public function woo_payment_success_filter($result, $order_id){
    if ( ! $order_id )
        return;
    $order = wc_get_order( $order_id );
    $order_data = $order->get_data();
    $order_email = $order->get_billing_email();
    $userInfo = get_user_by("email", $order_email);
    $userid = $userInfo->data->ID;
    $display_name = $userInfo->data->display_name;
    // Iterating through each "line" items in the order
    foreach ($order->get_items() as $item_id => $item ) {
        $product_name = $item['name'];
        $product_id = $item['product_id'];
        $product = wc_get_product( $product_id );
        if ( $product->is_type( 'simple' ) ) {
            $trial_period = get_post_meta( $product_id, PRODUCUT_TRIAL_PERIOD, true );
            if ( ! empty( $trial_period ) ) {
                $order->update_meta_data(PRODUCUT_TRIAL_PERIOD, $trial_period);
                $customFound = $order->get_meta("_customer_user", true); //In simple product Trial case mostly setting as 0 default;
                if(!$customFound){
                    update_post_meta($order_id, "_customer_user", $userid);
                }
                $order->add_order_note( "Payment event scheduled after ${trial_period} days" );
                $order->save();
                update_user_meta($userid, "lifetime_trial_purchase", "yes");
                // SETTING PAYMENT TOKEN
                if(isset($_REQUEST['stripe_source'])){
                    $customer_id = get_post_meta($order_id, "_stripe_customer_id", true);
                    $source_id = $_REQUEST['stripe_source'];
                    update_user_meta($userid, "_stripe_customer_id", $customer_id);
                    update_user_meta($userid, "_stripe_source_id", $source_id);
                    $stripe_customer = new WC_Stripe_Customer( $userid );
                    $stripe_customer_args = array(
                        "email" => $order_email,
                        "description" => "Name: ".$display_name,
                        "name" => $display_name,
                        "metadata" => array()
                    );
                    if(!$stripe_customer->get_user_id()){
                        try {
                            $stripe_customer->create_customer($stripe_customer_args);
                        } catch (Exception $e) {
                            // DELETE ORDER AND REDIRECT TO ERROR PAGE (Homepage)
                            // you are order can not be processed at the time, please try again later.
                            wp_delete_post($order_id, true);
                            wp_redirect(get_site_url().'/#trialError');
                            exit;
                        }
                    } else {
                        $stripe_customer->set_id($customer_id);
                        $stripe_customer->update_customer($stripe_customer_args);
                    }
                    $stripe_sources  = $stripe_customer->get_sources();
                    if($stripe_sources && is_array($stripe_sources) && count($stripe_sources) > 0){
                        $payment_token = WC_Payment_Tokens::get_customer_tokens( $userid, "stripe" );
                        if(!($payment_token && count($payment_token))){
                            try {
                                foreach ($stripe_sources as $key => $source) {
                                    if($source->status == "chargeable"){
                                        $wc_token = new WC_Payment_Token_CC();
                                        $wc_token->set_token( $source->id );
                                        $wc_token->set_gateway_id( 'stripe' );
                                        $wc_token->set_card_type( strtolower( $source->card->brand ) );
                                        $wc_token->set_last4( $source->card->last4 );
                                        $wc_token->set_expiry_month( $source->card->exp_month );
                                        $wc_token->set_expiry_year( $source->card->exp_year );
                                        $wc_token->set_user_id( $userid );
                                        $wc_token->save();
                                        break;
                                    }
                                }
                            } catch (Exception $e) {
                                wp_delete_post($order_id, true);
                                wp_redirect(get_site_url().'/#trialError');
                                exit;
                            }
                        }
                    } else {
                        try {
                            $stripe_customer->add_source($source_id);
                        } catch (Exception $e) {
                            wp_delete_post($order_id, true);
                            wp_redirect(get_site_url().'/#trialError');
                            exit;
                        }
                    }
                    $timestamp = strtotime( "+$trial_period days" );
                    $args = array( $order_id, 1, $userid, $product_id );
                    wp_schedule_single_event( $timestamp, 'process_payment_after_trial_ends', $args );
                }
            }
        }
    }
    return $result;
}

在上面的过滤器中，我试图在Stripe上创建/更新客户，并将其支付令牌与CC/源卡详细信息一起保存
在最后wp_schedule_single_event是设置后，试用时间将收取用户.代码是下面的收费客户.

    $product_price = $product->get_regular_price();

}
