如何從命令行啟動fiddler作為https代理？

Question

我需要自動啟動fiddler來解析https請求。

如何強制fiddler生成和使用沒有GUI的ssl證書？ 有誰知道小提琴手存放證書的地方？ 我可以生成自己的服務器證書並在沒有GUI的情況下將其設置為fiddler嗎？

我可以在退出模式下開始提琴手。 我可以通過注冊表項啟用https，但fiddler在沒有ssl證書的情況下啟動。 我可以創建使用makecert.exe的證書，但我不知道如何在沒有UI的情況下將其設置為fiddler的活動證書。

如果有人幫助我解決它，我會很高興。

沒有人幫助我，但我找到了解決方案。

解決方案：

要啟用捕獲https流量更新寄存器的值：

reg.exe add "HKEY_LOCAL_MACHINE\Software\Microsoft\Fiddler2" /v CaptureCONNECT /t REG_SZ /d True /f
reg.exe add "HKEY_LOCAL_MACHINE\Software\Microsoft\Fiddler2" /v CaptureHTTPS /t REG_SZ /d True /f
reg.exe add "HKEY_LOCAL_MACHINE\Software\Microsoft\Fiddler2" /v IgnoreServerCertErrors /t REG_SZ /d True /f

reg.exe add "HKEY_CURRENT_USER\Software\Microsoft\Fiddler2" /v CaptureCONNECT /t REG_SZ /d True /f
reg.exe add "HKEY_CURRENT_USER\Software\Microsoft\Fiddler2" /v CaptureHTTPS /t REG_SZ /d True /f
reg.exe add "HKEY_CURRENT_USER\Software\Microsoft\Fiddler2" /v IgnoreServerCertErrors /t REG_SZ /d True /f

您需要使用自定義fiddler的腳本。 它強制fiddler生成ssl證書（請參閱下面腳本CustomRules.js中的main部分）。 如果你不添加它，fiddler將在沒有ssl證書的情況下啟動。

copy /Y /V "<path to file>\CustomRules.js" "%userprofile%\Documents\Fiddler2\Scripts\CustomRules.js"

注意：請勿更改目標文件名。

當fiddler自動啟動時連接到套接字127.0.0.1:8888

start "" "%programfiles(x86)%\fiddler2\fiddler.exe" -quiet

小提琴手自動創建一個新的ssl證書。 它可以下載：

curl.exe -s -k -o <dst file path> "http://127.0.0.1:8888/FiddlerRoot.cer"

然后，您需要將其添加到受信任的根證書

certutil -addstore -f "Root" <path to certificate>

現在fiddelr已啟動，可以捕獲使用CustomRules.js的https流量。

Fiddler.bat：

@ECHO OFF

set currentDir=%~dp0
cd "%currentDir%"

set log="%currentDir%\fiddler.log"
set fiddler_custom_script_dir="%userprofile%\Documents\Fiddler2\Scripts\"
set fiddler_result_dir="C:\fiddler\"

start "" "%programfiles(x86)%\fiddler2\fiddler.exe" -quiet

set cert_path="%currentDir%\FiddlerRoot.cer"

    set /a attempt+=1
    timeout 1 > nul
    echo "Attempt #%attempt% to download fiddeler's certificate" >> "%log%"
    curl.exe -s -k -o "%cert_path%" "http://127.0.0.1:8888/FiddlerRoot.cer" >> "%log%"
if not exist "%cert_path%" if %attempt% LSS 300 goto get_cert

if not exist "%cert_path%" (
    echo "FAIL. Certificate "%cert_path%" doesn't exist. Cannot set trusted certificate"  >> "%log%"
    exit /b -100
)

set /a attempt=0
echo "Try to add certificate to trusted" >> "%log%"
echo certutil -addstore -f "Root" %cert_path% >> "%log%"
:import_cert
    set /a attempt+=1
    timeout 1 > nul
    echo "Attempt #%attempt% to download fiddeler's certificate" >> "%log%"
    certutil -addstore -f "Root" %cert_path% >> "%log%"
if "%errorlevel%" LSS 0 if %attempt% LSS 3 goto import_cert

echo "End..." >> "%log%"
exit /b 0

CustomRules.js

import System;
import System.Windows.Forms;
import Fiddler;

/**
 This script must be in the folder C:\Users\<USER>\Documents\Fiddler2\Scripts\CustomRules.js
 */
class Handlers
{
    // The Main() function runs everytime your FiddlerScript compiles
    static function Main() {
        var today: Date = new Date();
        FiddlerObject.StatusText = " CustomRules.js was loaded at: " + today;
        CertMaker.createRootCert();
        //CertMaker.GetRootCertificate().GetPublicKeyString()
    }
}
