FiddlerCore Edit response https not working.

[herson]

Hello. I need some help.  I have my website where I want

 
Hi, I need help. I'm using fiddlercore and C# I need to change a response on a website but it doesn't work.
In this case, I have a link that has texts in the response, such as text1 changing to text2, 
but nothing happens, the site opens without the changes. Am I missing something? Thank you very much.
private void FiddlerApplication_AfterSessionComplete(Session oSession)
{
    if (oSession.fullUrl.Contains("https:www.mysite/change.json") && oSession.HTTPMethodIs("GET"))
    {
        oSession.bBufferResponse = true;
        oSession.utilDecodeResponse();
        AppendTextRichBox2(GetSessionDetails(oSession));
        ModifyResponse(oSession, "text1", "text2");
        
    }
}
 private void ModifyResponse(Session oSession, string oldValue, string newValue)
        {
            string responseBody = oSession.GetResponseBodyAsString();
            responseBody = responseBody.Replace(oldValue, newValue);
            oSession.utilSetResponseBody(responseBody);
        }

Hello Herson,

 

In the provided snippet, you are using the AfterSessionComplete event which is when the response is already processed and is way too late to make any changes. To successfully modify a response use the BeforeResponse event.

More details on how to modify a response in FiddlerCore can be found in the following documentation article:
