Hello list,
in a Gnome Shell extension I want to connect with libsoup to a https://
URI which has a self-signed certificate.
My intention is to let the extension display the certificate to the user
and let the user decide whether to trust the certificate.
[...]
However, the line
let cert = msg.tls_certificate.certificate;
ist not exectuted. It prints an error message:
======================================================================
(gnome-shell:543): Gjs-WARNING **: JS ERROR: Error: Unable to introspect
element-type of container in GValue
======================================================================
Can someone help me understand this error message?
Unfortunately, it means that you can't use that property in GJS. The documentation for that property from the C API [1] says it is of type GByteArray*, and the GJS source code seems to suggest that such values are explicitly not yet supported in GJS [2].
Has someone a suggestion for a better solution?
If you just wanted the data you could use the 'certificate-pem' property [3]. As the documentation states, "This property and the “certificate” property represent the same data, just in different forms."
However, it seems like you can't construct a Gcr.Certificate object from the PEM-encoded data. I don't have a good solution for this.
