javascript - Chrome webrequest 在 requestBody 中看不到 POST 数据

coder 2025-02-12 原文

我在从 Facebook 操作获取 POST 数据时遇到问题。当您在 FB 上提交评论时，它会发布到此网址:https://www.facebook.com/ufi/add/comment/?__pc=EXP1%3ADEFAULT 在请求中，帖子的帖子数据存在: 这是来自帖子数据的实际评论的示例:

comment_text:test this is a test

当我尝试通过 Chrome 扩展程序访问它时，我似乎无法获取这些数据。我试过解析 requestBody，但它是空的。然后我尝试查看是否有任何其他请求方法可以工作，但我似乎无法在任何地方找到数据。

list .json:

    "scripts": [ "background.js" ]

上面未列出的任何其他监听器都没有输出。

有人知道吗？

最佳答案

您的 console.log 显示 requestBody 不为空。

你只需要解析原始字节:

If the request method is PUT or POST, and the body is not already parsed in formData, then the unparsed request body elements are contained in this array.

例如，如果发布的数据是一个字符串，那么您可以在 onBeforeRequest listener 中获取它的值:

var postedString = decodeURIComponent(String.fromCharCode.apply(null,
                                      new Uint8Array(details.requestBody.raw[0].bytes)));

根据站点脚本使用的编码，有很多方法可以解码字符串。

  1. ruby - 解析 RDFa、微数据等的最佳方式是什么，使用统一的模式/词汇(例如 schema.org)存储和显示信息 - 2

    我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i
