Chrome 扩展 - 如何获取 HTTP 响应正文? [英] Chrome Extension - How to get HTTP Response Body?

问题描述

这似乎是一个难题(或不可能??).我想在观看 Chrome 扩展程序后台脚本的情况下获取并阅读由浏览器中的 HTTP 请求引起的 HTTP 响应.我们可以通过这种方式获取HTTP Request Body

It seems to be difficult problem (or impossible??). I want to get and read HTTP Response, caused by HTTP Request in browser, under watching Chrome Extension background script. We can get HTTP Request Body in this way

chrome.webRequest.onBeforeRequest.addListener(function(data){
    // data contains request_body
},{'urls':[]},['requestBody']);

我也检查了这些stackoverflows

I also checked these stackoverflows

• Chrome 扩展程序 - 其他方式阅读响应正文而不是 chrome.devtools.network?
• Chrome 扩展读取 HTTP 响应

有没有什么聪明的方法可以在 Chrome 扩展中获取 HTTP 响应正文?

Is there any clever way to get HTTP Response Body in Chrome Extension?

推荐答案

我找不到比这个 anwser 更好的方法了.

I can't find better way then this anwser.

Chrome 扩展读取 HTTP 响应

答案告诉了如何获取响应标题并显示在另一个页面中.但是响应对象中没有正文信息(请参阅event-responseReceived).如果您想在没有其他页面的情况下获得响应 body，请尝试此操作.

The answer told how to get response headers and display in another page.But there is no body info in the response obj(see event-responseReceived). If you want to get response body without another page, try this.

var currentTab;
var version = "1.0";

chrome.tabs.query( //get current Tab
    {
        currentWindow: true,
        active: true
    },
    function(tabArray) {
        currentTab = tabArray[0];
        chrome.debugger.attach({ //debug at current tab
            tabId: currentTab.id
        }, version, onAttach.bind(null, currentTab.id));
    }
)


function onAttach(tabId) {

    chrome.debugger.sendCommand({ //first enable the Network
        tabId: tabId
    }, "Network.enable");

    chrome.debugger.onEvent.addListener(allEventHandler);

}


function allEventHandler(debuggeeId, message, params) {

    if (currentTab.id != debuggeeId.tabId) {
        return;
    }

    if (message == "Network.responseReceived") { //response return 
        chrome.debugger.sendCommand({
            tabId: debuggeeId.tabId
        }, "Network.getResponseBody", {
            "requestId": params.requestId
        }, function(response) {
            // you get the response body here!
            // you can close the debugger tips by:
            chrome.debugger.detach(debuggeeId);
        });
    }

}

我认为它对我来说已经足够有用了，您可以使用 chrome.debugger.detach(debuggeeId) 来关闭丑陋的提示.

I think it's useful enough for me and you can use chrome.debugger.detach(debuggeeId)to close the ugly tip.
