如何在 Chrome 中更改响应标头 [英] how to change response header in Chrome

问题描述

我正在处理互联网上的一些 mp3 链接.

I'm dealing with some mp3 link on the internet.

当使用 Chrome 开发者工具时，我看到一些响应头带有 Content-Type:application/octet-stream(像这样的链接强制 Chrome 下载)，一些链接带有响应头 Content-Type:audio/mpeg(这样的链接允许 Chrome 流式播放它们).

When using Chrome developer tool, I see some have response header with Content-Type:application/octet-stream (links like these force Chrome to download), some links have reponse header with Content-Type:audio/mpeg (links like these allow Chrome to play them streamingly).

是否有任何允许更改响应标头的 Chrome 扩展程序?因为我想改变Content-Type

Are there any Chrome extensions that allow changing response header? Because I want to change Content-Type

推荐答案

查看Chrome 开发者页面.

这是一个简单的例子，将 https://www.google.com/ 的 Content-Type 修改为 text/plain.

Here's a simple example that modifies Content-Type of https://www.google.com/ to text/plain.

chrome.webRequest.onHeadersReceived.addListener(details => {
    let header = details.responseHeaders.find(e => e.name.toLowerCase() === 'content-type') ;
    header.value = 'text/plain';
    return {responseHeaders: details.responseHeaders};
}, {urls: ['https://www.google.com/']}, ['blocking', 'responseHeaders']);

请注意，您必须在 manifest.json 中同时声明 webRequest 和 webRequestBlocking 权限.

Note that you have to declare both webRequest and webRequestBlocking permissions in manifest.json.
