如何在Chrome中更改响应标题 [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。

当使用Chrome开发者工具时，我看到一些响应标头包含 Content-Type：application / octet-stream （像这样的链接迫使Chrome下载），一些链接具有 Content-Type：audio / mpeg 的头部响应（这些链接允许Chrome以流的方式播放它们） p>

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

解决方案

请参阅

下面是一个简单的例子，它修改了 Content-Type https://www.google.com/ 改为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，您必须声明 webRequest 和 webRequestBlocking 权限 manifest.json 。

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

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).

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

解决方案

See the Chrome developer page.

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']);

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