What is the simple way to control the string generated by ContentType?

[Magicloud]

I am writing a webhook tool for a Go application, which checks the response content type via direct string equality.

And when I used ContentType::new("application", "json").with_params(("version", "1")) to set it, the result was "application/external.dns.webhook+json; version=1", which failed the comparison since in the Go code, there is no space before "version".

I wonder if there is a simple way I can remove the space.

hi @Magicloud ,

have you tried setting it directly in the Response? there's an example in the documentation on how you can do that.

Yes, it worked. Just that we have the ContentType and everything, if we can do this within its system.

I believe may actually be a bug in your Go tool. Based on the MIME type RFC (https://datatracker.ietf.org/doc/html/rfc2045#section-5.1), whitespace is allowed between parameters, but is not considered part of the parameter identifier. Therefore, according to the spec, text/plain; charset=UTF-8and text/plain;charset=UTF-8 should be considered identical content-types.

Ye, I checked the Go code, it is a string comparison. Anything technically allowed but not the same as the string would fail....
