    windows 10 connected to the internet through wifi, no proxy. I need to read a curl request to rewrite in c# code.

    using curl 7.61.0 and fiddler 5.

    this command just works fine:

      curl -X POST -u "73b63264-b68c-4591-af76-96f325969d0b":"X7bECApaBi0o" -F "file=@c:\temp\1.json" https://gateway-fra.watsonplatform.net/discovery/api/v1/environments/e40e7c0d-25de-4ae5-a079-90877a745de0/collections/029a29d3-2ed1-4cf3-be81-b78e35d5ce0f/documents?version=2017-11-07

    with fiddler running the command above works fine too ma no traced into fiddler.

    this command is traced into fiddler but fails to execute:

    curl --proxy http://127.0.0.1:8888 -X POST -u "73b63264-b68c-4591-af76-96f325969d0b":"X7bECApaBi0o" -F "file=@c:\temp\1.json" https://gateway-fra.watsonplatform.net/discovery/api/v1/environments/e40e7c0d-25de-4ae5-a079-90877a745de0/collections/029a29d3-2ed1-4cf3-be81-b78e35d5ce0f/documents?version=2017-11-07

    this the error "curl failed to verify the legitimacy of the server and therefore could not
    establish a secure connection to it. To learn more about this situation and
    how to fix it, please visit the web page mentioned above"

     

    Inspecting the requerst in fiddler , this the raw data of request, but i need to extract the body of request. How do i do?

    Thanks.

    Hello,

    It seems that curl does not trust Fiddler's root certificate as a certificate authority. You should get Fiddler's certificate (Tools -> Options -> HTTPS -> Actions -> Export Root Certificate to Desktop) and add it to curl's trusted CA certificate store.

    Regards,
