如何在Chrome中保存websocket框架 [英] How to save websocket frames in Chrome
问题描述
我使用Chrome / Developer Tools记录websocket流量。我没有问题在网络框架窗口中查看WebSocket框架,但我无法将所有框架(内容加密为JSON)保存在外部(文本)文件中。
我已经尝试保存为HAR,并且还简单地使用了cntl A,C,V(仅第一个页面被复制),但迄今为止并不是非常成功。
>解决方案
适用于Chrome 63的更新,2018年1月 我设法将它们导出为JSON,如下所示:
- detatch 活动检查器(如有必要) >
- 使用ctrl-shift-j / cmd-opt-j启动检查器上的检查器
- 将以下代码粘贴到该检查器实例中。
此时,您可以对框架进行任何操作。我从 console.save > https://bgrins.github.io/devtools-snippets/#console-save 将帧保存为JSON文件(包含在下面的代码片段中)。
// https://bgrins.github.io/devtools-snippets/#console-save
(函数(控制台){
console.save =函数(数据,文件名){
if(!data){
console.error('Console.save:No data')
return;
}
if(!filename)filename ='console.json'
if(typeof data ===object){
data = JSON.stringify(data,undefined, 4)
}
var blob = new Blob([data],{type:'text / json'}),
e = document.createEvent('MouseEvents'),
a = document.createElement('a')
a.download =文件名
a.href = window.URL.createObjectURL(blob)
a.dataset。 downloadurl = ['text / json (':')
e.initMouseEvent('click',true,false,window,0,0,0,0,0,false,false,false, false,0,null)
a.dispatchEvent(e)
}
})(控制台)
//框架/套接字消息计数器+文件名
var iter = 0;
//这将用原始代码
//替换浏览器的`webSocketFrameReceived`代码并添加两行,一行保存套接字消息,另一行保存计数器。
SDK.NetworkDispatcher.prototype.webSocketFrameReceived = function(requestId,time,response){
var networkRequest = this._inflightRequestsById [requestId];
if(!networkRequest)return;
console.save(JSON.parse(response.payloadData),iter +.json)
iter ++;
networkRequest.addFrame(response,time,false);
networkRequest.responseReceivedTime = time;
this._updateNetworkRequest(networkRequest);
}
这会将所有传入的套接字帧保存到您的默认下载位置。
I am logging websocket traffic using Chrome/Developer Tools. I have no problem to view the websocket frames in network "Frames" window, but I can not save all frames (content enc. as JSON) in an external (text) file. I have already tried save as HAR and also simply used cntl A,C,V (first "page" copied only) but have so far not been very successful.
I am running Linux Mint 17.
Do you have hints how this can be done?
Update for Chrome 63, January 2018
I managed to export them as JSON as this:
- detatch an active inspector (if necessary)
- start an inspector on the inspector with ctrl-shift-j/cmd-opt-j
- paste the following code into that inspector instance.
At this point, you can do whatever you want with the frames. I used the console.save
utility from https://bgrins.github.io/devtools-snippets/#console-save to save the frames as a JSON file (included in the snippet below).
// https://bgrins.github.io/devtools-snippets/#console-save
(function(console){
console.save = function(data, filename){
if(!data) {
console.error('Console.save: No data')
return;
}
if(!filename) filename = 'console.json'
if(typeof data === "object"){
data = JSON.stringify(data, undefined, 4)
}
var blob = new Blob([data], {type: 'text/json'}),
e = document.createEvent('MouseEvents'),
a = document.createElement('a')
a.download = filename
a.href = window.URL.createObjectURL(blob)
a.dataset.downloadurl = ['text/json', a.download, a.href].join(':')
e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
a.dispatchEvent(e)
}
})(console)
// Frame/Socket message counter + filename
var iter = 0;
// This replaces the browser's `webSocketFrameReceived` code with the original code
// and adds two lines, one to save the socket message and one to increment the counter.
SDK.NetworkDispatcher.prototype.webSocketFrameReceived = function (requestId, time, response) {
var networkRequest = this._inflightRequestsById[requestId];
if (!networkRequest) return;
console.save(JSON.parse(response.payloadData), iter + ".json")
iter++;
networkRequest.addFrame(response, time, false);
networkRequest.responseReceivedTime = time;
this._updateNetworkRequest(networkRequest);
}
This will save all incoming socket frames to your default download location.
