One example is app NTlite which is used for modifying windows 7 setup and downloading updates manually. I wanted to see list of these updates it downloads fronm, but it is encrypted, and some message about storing certificate was displayed quickly in fiddler but disappeared. I already have root certificate so I can see most apps and system (svchost) https traffic. But this app is different. I use windows 7 x64 enterprise.

I am running Fiddler 5.0.20182.28034 on a Windows 10 standalone laptop and need to track traffic from Genymotion emulator. In the emulator, I've set up Samsung S8 with Android version 8.0. The option of allowing remote computers to connect is checked and I've also installed the Fiddler's certificate in the device. However, when in the proxy settings of the device in the emulator, I provide the IP address of Fiddler with port 8888 and try to connect to the WiFi, the device is unable to get the IP address. Can someone help me out on how to resolve this problem.

I'm testing Fidler Everywhere on OSX Mojave and the option to export the root certificate is greyed out, so I'm unable to decrypt.

Any ideas?

Just installed last version, but when i double click fiddler.exe absolutely nothing happens, pls help

Download redirects to  http://telerik-fiddler.s3.amazonaws.com/fiddler-latest/progress-telerik-fiddler.AppImage which doen not get resolved by chrome. Even ping not working for telerik-fiddler.s3.amazonaws.com

hello, i am doing a program that sends requests through alternating proxies (two). However, in fiddler there is only the possibility to specify one proxy, is there a way to edit the script so as to work through both proxies?

using fiddlercore i want to use some info from request and add some info to request and create a new request and send it to a server.

How can I send?

Hi 

Now I am running with

var oJSON = Newtonsoft.Json.JsonConvert.DeserializeObject(oS.GetRequestBodyAsString());
var t = oJSON.JSONObject["target"]

........

But sometimes the oS.GetRequestBodyAsString() is not a valid json string.

Is there any way to check the oJSON status to see if the job is done without errors?

For example,

var oJSON = Newtonsoft.Json.JsonConvert.DeserializeObject(oS.GetRequestBodyAsString());

if (!oJSON.isSuccessful) {

    // process error and return

} 

 

I have a Windows service that is sending encrypted HTTP traffic.  I have set up Fiddler to decrypt  HTTPS traffic. I have logged in as the user whom this service is set to log in as. Though the service is creating traffic, I'm getting no traffic in Fiddler.

This seems to be happening on Windows 2016 servers. I have a Windows 2008 server on which the same service is running and I'm getting traffic just fine.  Does anyone know what might be the issue?

In CustomRules.js

static function OnBeforeResponse(oSession: Session) {

        var responseStringOriginal =  oSession.GetResponseBodyAsString();

        var responseJSON = Fiddler.WebFormats.JSON.JsonDecode(responseStringOriginal);
        var responseJSONObject = responseJSON.JSONObject;
}

 

 

 

There is an array in response responseJSONObject , like 

[
    {
        "id": "6661370502453447944"

    },

    { 

        "id": "333" 

    },

    ...

]

 

Question 1: How can I get this array's length or traversal this array?

 

Question 2: How can I create an array using for loop and save the new array to the responseJSON.JSONObject?

 

Question 3: Where can I find any documentation about this object "Fiddler.WebFormats.JSON", like what method and properties it have.

 

I tried several ways but nothing works and I can't using the JSON.parse() function in this script.

I also google for the documents of  this object (Fiddler.WebFormats.JSON) and found nothing.

 

 

Thank you very much and welcome reply any infomation.
