解决方法
webRequest API可用于修改User Agent标头.
注意：Developer工具的Network选项卡显示旧标题.我已经使用 netcat(nc -l 127.0.0.1 -p 6789)验证了标题设置正确.
在下面的示例中,代码在所有选项卡上激活.调整request filter以满足您的要求.添加tabId以限制此过滤器的功能,使用选项卡的tabId(可通过各种API获取,特别是chrome.tabs).
background.js
chrome.webRequest.onBeforeSendHeaders.addListener(
function(info) {
// Replace the User-Agent header
var headers = info.requestHeaders;
headers.forEach(function(header,i) {
if (header.name.toLowerCase() == 'user-agent') {
header.value = 'Spoofed UA';
}
});
return {requestHeaders: headers};
},// Request filter
{
// Modify the headers for these pages
urls: [
"https://stackoverflow.com/*","http://127.0.0.1:6789/*"
],// In the main window and frames
types: ["main_frame","sub_frame"]
},["blocking","requestHeaders"]
);
的manifest.json
{
"name": "WebRequest UA test","version": "1.0","permissions": ["webRequest","webRequestBlocking","http://*/*"],"background": {
"scripts": ["background.js"]
},"manifest_version": 2
}
