c语言将时间戳转换成RFC822格式时间 - 你不知道的浪漫

公告

笔者今天是节后最后一班,想总结一些tomcat里面经常提及的RFC规范，于是用工具从github检出tomcat代码，

地址https://github.com/apache/tomcat/，搜索了一些RFC偶尔发现以下代码

org.apache.tomcat.jni.Time.java

/**
   * Formats dates in the RFC822
   * format in an efficient manner.
   * @param t the time to convert
   * @return the formatted date
*/
public static native String rfc822(long t);

大意：以高效的方式将日期格式化成RFC822标准的格式。在java里面native方法全部都是通过对应的本地代码（C语言）实现的。

笔者在tomcat相关的本地库（Tomcat Native、Tomcat Connectors）最终在tomcat-native中找到相关代码。

关于Tomcat Native的官方描述:

The Apache Tomcat Native Library is an optional component for use with Apache Tomcat that allows Tomcat to use certain native

resources for performance, compatibility, etc.Specifically, the Apache Tomcat Native Library gives Tomcat access to the Apache

Portable Runtime (APR) library's network connection (socket) implementation and random-number generator. See the Apache Tomcat

documentation for more information on how to configure Tomcat to use the APR connector.

大意：

Apache Tomcat本地库是一个可选组件，可用于Apache Tomcat，为了性能和兼容性等，允许Tomcat使用
某些本机资源。

具体而言，Apache Tomcat本地库允许Tomcat访问Apache Portable Runtime(APR)库的网络连接(套接字)实现
和随机数生成器。有关如何配置Tomcat使用APR连接器的详细信息，请参阅Apache Tomcat文档。

代码位置如下

tomcat-native-1.2.23-src/native/src/misc.c

其中有rfc822关键字，再比对一下我们Time.java对应的类

package org.apache.tomcat.jni;

    public static native void sleep(long t);

}

其中sleep、ctime、rfc822、now都在这里，这类应该和Time.java代码有关系了。再看了一下这个c语言类,他使用的apr库,

APR(Apache Portable Runtime)的库地址:https://apr.apache.org/

APR官方介绍：

The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent

interface to underlying platform-specific implementations. The primary goal is to provide an API to which software developers may code and be

assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code

special-case conditions to work around or take advantage of platform-specific deficiencies or features.

大意：

Apache 可移植运行时（APR）项目的任务是创建和维护软件库，为底层特定于平台的实现提供可预测且一致的接口。
主要目标是提供一个 API，软件开发人员可以对此进行编码，并确保无论软件构建的平台如何，都能实现可预测的
（如果不是相同的行为），从而免除了为了正常工作而编写特定情形、或者使用依赖于特定平台的缺陷或者特性的代码。

再对比以上Tomcat Native Library官方说明，一一对应。于是我们就可以认为misc.c封装了特定平台的细节，我们通过这个结果就能实现跨平台的本地代码功能。

至此，笔者想起8年前的前同事写的一段代码，他也用apr写的，能跨平台，瞬间也明白了apr的作用，为跨平台而生。

快速学习思路

笔者目前对apr还不熟悉，特别以上的misc.c中宏/形参,笔者知道一种方法：使用IDA反汇编可以看到函数原型（方法签名），于是尝试在linux环境（比windows方便，

windows编译麻烦，可以快速实现目的，实际上windows编译时候默认会把调试信息放到同级目录，反汇编效果更好）下编译了一下tomcat-native代码，在linux下编译

了结果，然后把中间文件、调试信息等拿回来到本地，使用DA_Pro_v7.0逆向一下tomcat-native-1.2.21-src\native\.libs目录文件libtcnative-1.so，使用F5插件得到伪代码。

Time.java中rfc822、ctime、sleep对应的JNI代码

//----- (0000000000015690) ----------------------------------------------------

OS.java中对应于random的JNI代码

/**

public static native int random(byte [] buf, int len);

  jint v7; // ebp
  JNIEnv v8; // rax

  v4 = buf;
  v5 = len;
  v6 = ((__int64 (__fastcall *)(JNIEnv *, jbyteArray, _QWORD))(*e)->GetPrimitiveArrayCritical)(e, buf, 0LL);
  v7 = apr_generate_random_bytes(v6, v5);
  v8 = *e;
  if ( v7 )
    ((void (__fastcall *)(JNIEnv *, jbyteArray, __int64, signed __int64))v8->ReleasePrimitiveArrayCritical)(
      e,
      v4,
      v6,
      2LL);
  else
    ((void (__fastcall *)(JNIEnv *, jbyteArray, __int64, _QWORD))v8->ReleasePrimitiveArrayCritical)(e, v4, v6, 0LL);
  if ( ((unsigned __int8 (__fastcall *)(JNIEnv *))(*e)->ExceptionCheck)(e) )
  {
    v7 = 20014;
    ((void (__fastcall *)(JNIEnv *))(*e)->ExceptionClear)(e);
  }
  return v7;
}

通过作者逐步搜索，终于找到了rfc822对应的unix/win32平台的c代码，不到黄河心不死的人终于翻出来代码。

项目地址：https://github.com/apache/apr

代码里有rfc822、ctime代码，另外一个文件time.c代码里面有sleep相关代码。感兴趣的朋友翻阅apr官方源码吧，也可以根据misc.c去翻阅对应的apr实现。
