chrome.webRequest.onBeforeSendHeaders.addListener(function(details){
    var headers = details.requestHeaders
    details.requestHeaders.push({
        name:"Referer",
        value:`来源`
	}
	// ,

    )
    console.log(headers)
    return {requestHeaders: details.requestHeaders}
},{urls: ["要伪造的地址"]},
["requestHeaders", "blocking", "extraHeaders"]);
