Question

我使用Spark web framework开发REST API。有没有办法自动记录所有传入的请求和传出的响应（查询参数，标题，状态代码等），还是我需要为每个处理程序手动添加日志记录？

Spark文档中没有关于此主题的内容。

感谢。

Answer 1

这是我的解决方法。

private static String requestInfoToString(Request request) {
    StringBuilder sb = new StringBuilder();
    sb.append(request.requestMethod());
    sb.append(" " + request.url());
    sb.append(" " + request.body());
    return sb.toString();
}

public static void main(String[] args) {
    // Bunch of handlers

    before((request, response) -> {
        log.info(requestInfoToString(request));
    });
}

以乔的回答为基础......这里有一个既要求又回应的版本：

public static void main(String[] args) {
    ... all your other handlers

    // add logger
    after((request, response) -> {
        LOG.info(requestAndResponseInfoToString(request, response));
    });
}

private static String requestAndResponseInfoToString(Request request, Response response) {
    StringBuilder sb = new StringBuilder();
    sb.append(request.requestMethod());
    sb.append(" " + request.url());
    sb.append(" " + request.body());
    HttpServletResponse raw = response.raw();
    sb.append(" Reponse: " + raw.getStatus());
    sb.append(" " + raw.getHeader("content-type"));
    try {
        sb.append(" body size in bytes: " + response.body().getBytes(raw.getCharacterEncoding()).length);
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return sb.toString();
}

Answer 3

这应该足够了：

public static void main(String[] args) {
    // add logger
    after((request, response) -> {
        LOG.info(String.format("%s %s", request.requestMethod(), request.url()));
    });
}
