Javascript Chrome webrequest没有'；在requestBody中看不到POST数据

我在从Facebook操作获取帖子数据时遇到问题。当您提交关于FB的评论时，it会将其发布到此url： 在请求中，存在post的post数据： 以下是来自post数据的实际注释示例：

comment_text:test this is a test

---

当我试图通过Chrome扩展访问此文件时，我似乎无法获取此数据。我已尝试解析requestBody，但它是空的。然后我试着看看其他的requestmethods是否有效，但我似乎在任何地方都找不到数据

有人知道吗？

您的console.log显示

requestBody

不是空的

您只需解析

根据站点脚本使用的编码，有许多方法可以解码字符串。

请求正文可能不存在的另一个原因是，extraInfoSpec必须包含“requestBody”，如下所示

chrome.webRequest.onBeforeRequest.addListener(
    function(details)
    {
        console.log(details.requestBody);
    },
    {urls: ["https://myurlhere.com/*"]},
    ['requestBody']
);

requestBody

是否真的为空，即是否缺少所有键…？“我已尝试解析requestBody，但它为空”。你的密码在哪里？你怎么知道它是空的？我不确定它是空的还是钥匙不见了。我所知道的是我正在转储所有细节，这就是我得到的：“requestBody”：{“raw”：[{“bytes”：{}}}谢谢。这是正确的答案。我没有意识到原始区域中有数据。我曾尝试将该数据打印到控制台，但没有实现该方法。仅供参考，您似乎缺少结尾处的右括号，+1，但这可能会截断raw具有多个条目的请求正文。您需要对每个原始条目进行说明。本质上，将每个字符串转换为一个字符串并将它们连接起来。类似这样的

details.requestBody.raw.map（函数（数据）{return String.fromCharCode.apply（null，new-Uint8Array（data.bytes））}）。join（“”）

chrome.webRequest.onBeforeRequest.addListener(
    function(details)
    {
        console.log(details.requestBody);
    },
    {urls: ["https://myurlhere.com/*"]},
    ['requestBody']
);
