在IT领域，特别是网络安全和数据分析中，解密技术扮演着至关重要的角色。本文将深入探讨“知乎x-zse-96文件头JS解密”这一主题，旨在帮助读者理解相关概念和技术。我们需要了解“知乎x-zse-96”是什么。知乎是中国一个知名的问答社区，为了保护用户数据安全和防止爬虫抓取，它可能会使用自定义的加密算法，如x-zse-96，对网页内容进行加密。这种加密方式可能是为了保护用户的隐私和平台的知识产权，防止未经授权的数据获取。 “文件头”通常指的是文件的起始部分，它包含了关于文件类型、格式、编码等信息。在JS（JavaScript）文件中，文件头可能包含执行脚本的元数据或特定的加密指示。在解密过程中，识别和解析这些文件头是至关重要的步骤，因为它们提供了解密算法的线索。解密JS文件通常涉及以下几个步骤： 1. **分析文件结构**：我们需要读取JS文件，理解其内部结构，包括函数、变量和代码块的布局。这有助于我们找到可能与加密和解密相关的代码段。 2. **查找加密函数**：在JS代码中，查找可能用于加密的函数，这些函数可能使用了某种加密库或者自定义的加密算法。在“g_encrypt.js”这个文件中，很可能就包含了加密逻辑。 3. **逆向工程**：一旦找到加密函数，我们需要通过逆向工程来理解其工作原理。这可能涉及到对函数参数、返回值的分析，以及对复杂逻辑的跟踪。 4. **解密函数构造**：基于对加密逻辑的理解，我们可以尝试构建对应的解密函数。这通常需要模拟加密过程，并逆向操作以达到解密的目的。 5. **测试和验证**：我们需要编写测试用例，确保解密函数能够正确还原原始数据。在“zhihu.py”这个Python文件中，可能已经包含了用于解密和测试的代码。 6. **解密实战**：对于“node_modules”目录，它通常包含Node.js环境下的依赖库。这些库可能被用于实现加密和解密，或者是辅助工具。分析这些模块可以帮助我们更好地理解整个解密流程。需要注意的是，解密技术涉及版权和法律问题，因此在实际操作时必须遵守相关法律法规，尊重他人的知识产权，仅用于合法的学术研究或授权的项目。总结来说，“知乎x-zse-96文件头JS解密”是一项复杂的任务，它涵盖了JS文件分析、加密算法逆向工程、解密函数构建等多个环节。理解和掌握这些技能对于网络安全专家、数据分析师以及Web开发者来说都是非常有价值的。通过深入学习和实践，不仅可以提升技术水平，还能增强对网络数据安全的敏感度和保护意识。

<h1 align="center"> <img width="100" height="100" src="logo.svg" alt=""><br> jsdom </h1> jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG [DOM](https://dom.spec.whatwg.org/) and [HTML](https://html.spec.whatwg.org/multipage/) Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v12 or newer. (Versions of jsdom below v17 still work with previous Node.js versions, but are unsupported.) ## Basic usage ```js const jsdom = require("jsdom"); const { JSDOM } = jsdom; ``` To use jsdom, you will primarily use the `JSDOM` constructor, which is a named export of the jsdom main module. Pass the constructor a string. You will get back a `JSDOM` object, which has a number of useful properties, notably `window`: ```js const dom = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`); console.log(dom.window.document.querySelector("p").textContent); // "Hello world" ``` (Note that jsdom will parse the HTML you pass it just like a browser does, including implied `<html>`, `<head>`, and `<body>` tags.) The resulting object is an instance of the `JSDOM` class, which contains a number of useful properties and methods besides `window`. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern like ```js const { window } = new JSDOM(`...`); // or even const { document } = (new JSDOM(`...`)).window; ``` Full documentation on everything you can do with the `JSDOM` class is below, in the section "`JSDOM` Object API". ## Customizing jsdom The `JSDOM` constructor accepts a second parameter which can be used to customize your jsdom in the following ways. ### Simple options ```js const dom = new JSDOM(``, { url: "https://example.org/", referrer: "https://example.com/", contentType: "text/html", includeNodeLocations: true, storageQuota: 10000000 }); ``` - `url` sets the value returned by `window.location`, `document.URL`, and `document.documentURI`, and affects things like resolution of relative URLs within the document and the same-origin restrictions and referrer used while fetching subresources. It defaults to `"about:blank"`. - `referrer` just affects the value read from `document.referrer`. It defaults to no referrer (which reflects as the empty string). - `contentType` affects the value read from `document.contentType`, as well as how the document is parsed: as HTML or as XML. Values that are not a [HTML mime type](https://mimesniff.spec.whatwg.org/#html-mime-type) or an [XML mime type](https://mimesniff.spec.whatwg.org/#xml-mime-type) will throw. It defaults to `"text/html"`. If a `charset` parameter is present, it can affect [binary data processing](#encoding-sniffing). - `includeNodeLocations` preserves the location info produced by the HTML parser, allowing you to retrieve it with the `nodeLocation()` method (described below). It also ensures that line numbers reported in exception stack traces for code running inside `<script>` elements are correct. It defaults to `false` to give the best performance, and cannot be used with an XML content type since our XML parser does not support location info. - `storageQuota` is the maximum size in code units for the separate storage areas used by `localStorage` and `sessionStorage`. Attempts to store data larger than this limit will cause a `DOMException` to be thrown. By default, it is set to 5,000,000 code units per origin, as inspired by the HTML specification. Note that both `url` and `referrer` are canonicalized before they're used, so e.g. if you pass in `"https:example.com"`, jsdom will interpret that as if you had given `"https://example.com/"`. If you pass an unparseable URL, the call will throw. (URLs are parsed and serialized according to the [URL Standard](https://url.spec.whatwg.org/).) ### Executing scripts jsdom's most powerful ability is that it can execute scripts inside the jsdom. These scripts can modify the content of the page and access all the web platform APIs jsdom implements. However, this is also highly dangerous when dealing with untrusted content. The jsdom sandbox is not foolproof, and code running inside the DOM's `<script>`s can, if it tries hard enough, get access to the Node.js environment, and thus to your machine. As such, the ability to execute scripts embedded in the HTML is disabled by default: ```js const dom = new JSDOM(`<body> <script>document.body.appendChild(document.createElement("hr"));</script> </body>`); // The script will not be executed, by default: dom.window.document.body.children.length === 1; ``` To enable executing scripts inside the page, you can use the `runScripts: "dangerously"` option: ```js const dom = new JSDOM(`<body> <script>document.body.appendChild(document.createElement("hr"));</script> </body>`, { runScripts: "dangerously" }); // The script will be executed and modify the DOM: dom.window.document.body.children.length === 2; ``` Again we emphasize to only use this when feeding jsdom code you know is safe. If you use it on arbitrary user-supplied code, or code from the Internet, you are effectively running untrusted Node.js code, and your machine could be compromised. If you want to execute _external_ scripts, included via `<script src="">`, you'll also need to ensure that they load them. To do this, add the option `resources: "usable"` [as described below](#loading-subresources). (You'll likely also want to set the `url` option, for the reasons discussed there.) Event handler attributes, like `<div onclick="">`, are also governed by this setting; they will not function unless `runScripts` is set to `"dangerously"`. (However, event handler _properties_, like `div.onclick = ...`, will function regardless of `runScripts`.) If you are simply trying to execute script "from the outside", instead of letting `<script>` elements and event handlers attributes run "from the inside", you can use the `runScripts: "outside-only"` option, which enables fresh copies of all the JavaScript spec-provided globals to be installed on `window`. This includes things like `window.Array`, `window.Promise`, etc. It also, notably, includes `window.eval`, which allows running scripts, but with the jsdom `window` as the global: ```js const { window } = new JSDOM(``, { runScripts: "outside-only" }); window.eval(`document.body.innerHTML = "<p>Hello, world!</p>";`); window.document.body.children.length === 1; ``` This is turned off by default for performance reasons, but is safe to enable. (Note that in the default configuration, without setting `runScripts`, the values of `window.Array`, `window.eval`, etc. will be the same as those provided by the outer Node.js environment. That is, `window.eval === eval` will hold, so `window.eval` will not run scripts in a useful way.) We strongly advise against trying to "execute scripts" by mashing together the jsdom and Node global environments (e.g. by doing `global.window = dom.window`), and then executing scripts or test code inside the Node global environment. Instead, you should treat jsdom like you would a browser, and run all scripts and tests that need access to a DOM inside the jsdom environment, using `window.eval` or `runScripts: "dangerously"`. This might require, for example, creating a browserify bundle to execute as a `<script>` element—just like you would in a browser. Finally, for advanced use cases you can use the `dom.getInternalVMContext()` method, documented below. ### Pretending to be a visual browser jsdom does not have the capability to render visual content, and will act like a headless browser by default. It provides hints to web pages through APIs such as `document.hidden` that their content is not visible.
