Python之JavaScript逆向系列——2、Headers请求头



前言

大家好,本系列文章主要为大家提供的价值方向是网络信息获取,自动化的提取、收集、下载和记录互联网上的信息,加之自身分析,可以让价值最大化。整个内容中不会涉及到过为敏感的内容。

在这个AI+云计算+大数据时代,我们眼睛所看到的百分之九十的数据都是通过页面呈现出现的,不论是PC端、网页端还是移动端,数据渲染还是基于HTML+JavaScript进行的,而大多数的数据都是通过request请求后台API接口动态渲染的。而想成功的请求成功互联网上的开放/公开接口,必须知道它的【URL】、【Headers】、【Params】、【Body】等数据是如何生成的。我们需要了解浏览器开发者工具的功能,入门JS逆向,入门后还需要掌握例如如何【反编译js混淆】等内容,为了避免封本机IP,还需要对每次访问的IP进行代理,当我们拥有了JS逆向的能力后,根据JS所返回的动态请求参数信息便可以进行Python的具体信息获取操作,需要的知识点非常的多,故而本系列文章理论+实践会达到上百篇的文章,这篇文章是总篇,为了方便大家来直接查找所有知识点,建议之间关注收藏本篇,期望能给大家带来更高的价值。

正文

Headers也就是头部信息,这里的内容是比较多的。我们需要深入的玩耍一下,如果仅仅想知道如何正确使用就直接看【User-Agent】这个参数就行了。

Headers是HTTP协议中的一个重要组成部分,它包含了服务器或客户端发送给另一端的信息,用于解释文件的内容和用途。在许多情况下,Headers可以被视为数据的一部分,并且可以通过请求或响应一起发送。

Headers的详细介绍:

1. 定义:Headers是HTTP请求或响应的一部分,用于提供有关文件的信息。这些信息通常包括文件类型、大小、日期、语言、字符集等。

2. 类型:Headers可以分为请求头(Request Headers)和响应头(Response Headers)。请求头通常在客户端发送请求时提供,而响应头在服务器响应请求时提供。此外,还有一种特殊的头部称为附加头部(Additional Headers),它可以在客户端和服务器之间传递任何额外信息。

3. 主要作用:Headers的主要作用包括标识文件类型、提供身份验证信息、跟踪请求/响应状态、提供缓存信息等。此外,Headers还可以用于跟踪用户行为、提供个性化体验和进行安全检查。

4. 常见Header:以下是一些常见的Headers:

   * Content-Type:指定文件的内容类型,例如文本、图像、音频、视频等。

   * Content-Length:指定文件的大小(以字节为单位)。

   * Accept:指定客户端可以接受的响应内容类型。

   * User-Agent:提供有关发出请求的客户端的信息,例如浏览器类型和版本。

   * Cookie:用于在客户端存储会话信息,以便在多个请求之间保持状态。

   * Authorization:用于提供身份验证信息,例如用户名和密码。

5. 解析和操作Headers:客户端和服务器通常使用编程语言中的库来解析和处理Headers。这些库通常提供了一些方法来获取、设置和删除Headers。此外,一些库还提供了过滤和排序Headers的功能,以便根据特定条件对它们进行处理。

6. 安全注意事项:在处理Headers时,应该注意保护敏感信息,例如密码和用户身份验证信息。确保Headers不被恶意软件或未经授权的第三方获取,并遵循最佳安全实践。

7. 性能优化:Headers可能会影响请求和响应的速度。在某些情况下,减少不必要的Headers或使用压缩算法可以优化性能。

总之,Headers是HTTP协议中不可或缺的一部分,它们提供了关于文件的重要信息,并有助于实现各种功能,如身份验证、状态跟踪、缓存等。了解和处理Headers对于正确理解和处理HTTP请求和响应至关重要。

请求头客户端——超级大集合

以下的python在请求的时候User-Agent集合,随机使用。

JSON JavaScript 前端开发
在Python中调用和执行JavaScript
在Python中调用和执行JavaScript主要通过`PyExecJS`库实现。安装库后,可以使用`execjs.compile`编译JS代码并用`eval`或`call`执行。此外,还能加载JavaScript库和框架,调用外部JS文件,处理返回值,以及在两者间传递数据。Python和JavaScript各有优劣,适用于不同场景,结合使用可增强项目功能和灵活性。
