GWT 中的 post 令牌是如何生成的？

发布于 2024-08-19 11:28:36 字数 341 浏览 4 评论 0原文

我有这样的请求：

5|0|7|http://localhost:8080/testproject/|29F4EA1240F157649C12466F01F46F60|com.test.client.GreetingService|greetServer|java.lang.String|myInput1|myInput2|1|2|3|4|2|5|5|6|7|

我想知道 GWT 如何生成 md5 值 29F4EA1240F157649C12466F01F46F60？是基于客户端ip和日期吗？谁能指出我正确的代码吗？我只是找到了有关历史令牌的内容，但这对我来说看起来不同。

I have requests like

5|0|7|http://localhost:8080/testproject/|29F4EA1240F157649C12466F01F46F60|com.test.client.GreetingService|greetServer|java.lang.String|myInput1|myInput2|1|2|3|4|2|5|5|6|7|

I would like to know how GWT generates the md5 value 29F4EA1240F157649C12466F01F46F60? Is it based on the client ip and date? Can anyone point me to the correct code? I just find stuff regarding the history token, but that looks different to me.

好的，经过一番研究，我想我找到了答案。
您应该寻找的关键字是“strong name ”（或“strongName ”）和/或排列，因为看起来他们发送 RPC 请求的排列强名称（MD5 哈希），以便您可以在服务器端区分请求是发送的排列。
核心功能是 Util.computeStrongName，它计算提供的字节数组的 MD5 哈希值 (d'oh)，并添加了以下内容：

/*
 * Include the lengths of the contents components in the hash, so that the
 * hashed sequence of bytes is in a one-to-one correspondence with the
 * possible arguments to this method.
 */

从那里，我追溯到链接器，然后排列结果< /a> 通过此函数提供 Util.computeStrongName ：

/**
 * The compiled JavaScript code as UTF8 bytes.
 */
byte[][] getJs();

呃，我希望这至少有点帮助；）如果这仍然不能回答你的问题（或者你正在寻找不同的东西）），尝试 trunk/user/src/com/google/gwt/user/client/rpc（从 RpcRequestBuilder.java）。

OK, after some research I think I found the answer.
The keywords you should have been looking for are "strong name" (or "strongName") and/or permutation, since it seems that with the RPC request they send out the permuatation strong name (that MD5 hash), so that you can possibly distinguish on the server side from which permutation the request was send.
The core function is Util.computeStrongName, it computes an MD5 hash (d'oh) of the provided byte array, with the added catch:

/*
 * Include the lengths of the contents components in the hash, so that the
 * hashed sequence of bytes is in a one-to-one correspondence with the
 * possible arguments to this method.
 */

From there, I tracked back to the linkers and then to PermutationResult which is feeding Util.computeStrongName via this function:

/**
 * The compiled JavaScript code as UTF8 bytes.
 */
byte[][] getJs();

Eh, I hope that was at least a bit helpful ;) If this still doesn't answer your question (or you were looking for something different), try in trunk/user/src/com/google/gwt/user/client/rpc (start in RpcRequestBuilder.java).

正如 Igor 所说，GWT 使用应用程序代码的 MD5 哈希值来为应用程序的每个版本的每个排列生成唯一的名称。您引用的特定哈希是 GWT RPC 请求负载的一部分，用于标识服务器上的 .gwt.rpc 序列化策略文件。该策略文件说明哪些 Java 对象可以序列化为 GWT RPC 服务中请求、响应或抛出异常的一部分。
