我在从Facebook操作中获取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： 以下是帖子数据中实际评论的示例：
comment_text:test this is a test
当我尝试通过Chrome扩展程序访问此内容时，我似乎无法获取此数据。我试过解析requestBody，但它是空的。然后我试着看看是否有其他请求方法可以工作，我似乎无法在任何地方找到数据。

上面未列出的任何其他听众都没有输出。
有人有任何想法吗？
答案 0 :(得分：12)
您的console.log显示requestBody 不为空。
您只需要解析raw个字节：
如果请求方法是PUT或POST，并且尚未在formData中解析正文，则未解析的请求正文元素包含在此数组中。
例如，如果发布的数据是字符串，那么您可以在onBeforeRequest listener中获取其值：
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，有许多方法可以解码字符串。
答案 1 :(得分：0)
之所以可能不存在请求正文的另一个原因是因为extraInfoSpec必须按如下所示包含“ requestBody”。
chrome.webRequest.onBeforeRequest.addListener(
function(details)
{
console.log(details.requestBody);
},
{urls: ["https://myurlhere.com/*"]},
['requestBody']
);
