Salute to fellow Gophers.

I need to return the data matrix in base64 form in the html template. In the template it looks like this. <img src="data:image/png;base64,%7B%7B.+%20Use%20html/template%20golang%20in%20base64%7D%7D" alt="+ Use html/template golang in base64">

I insert my Base64 data into a .+ Use html/template golang in base64. all is well. Base64 is valid and all (checked on different decoders), but when I pass the data to template (plus) symbols, the symbols change to +

Encode base64 like this: base64.StdEncoding.EncodeToString(b)

Also tried base64.URLEncoding.EncodeToString(b), but more symbols got messed up.

Pass parameters as structure fields of type string

Try passing it in different ways: as type template.HTML, using template.HTMLEscapeString, template.URLEscapeString, template.JSEscapeString , but no result.

We would be very grateful for a valid solution to this problem.

P>S> Changing to text/template is also not an option. In the actual project, I also have a few things injected into the templates, but they simply don't work with the text/template library.

Solution

Surprisingly, enough text/templates solved all the problems. and did not cause any new problems with other injections.
