Is there any way to escape a variable template in a string?

[k33nice]

Say, I need to pass a string with {{template}} directly without hurl trying to replace it by variable template, e.g:

POST http://foo.test
{
  "template": "{\"foo\": \"some string with template {{some_var}}\"}"
}

I've tried "{\"foo\": \"some string with template \{\{some_var\}\}"\"}, but it not works.

The workaround I found is

POST http://foo.test
[Options]
variable: openBrace={
variable: closeBrace=}
{
  "template": "{\"foo\": \"some string with template {{openBrace}}{some_var}{{closeBrace}}\"}"
}

but it looks hacky.

Hi k33nice, it's not pretty for the moment, you can use unicode JSON literal :

• {=> \u007b
• }=> \u007d

So instead of

POST https://foo.com
{ 
 "foo": "{{bar}}"
}

You can write:

POST https://foo.com
{ 
 "foo": "\u007b\u007bbar\u007d\u007d"
}

If you can test it on your side, I'm curious if it's working.

We've an issue to introduce a "raw" multiline string that won't do any variable resolution:

#1733

With this we should be able to write:

POST https://foo.com
Content-Type: application/json
```raw
{ 
 "foo": "{{bar}}"
}
```

We'll try to improve this!

Appreciated! Yeah, unicode characters work as well. But personally, I found the approach with variables for braces more obvious (unless you have a unicode table in your mind :)).
The raw would be awesome for my case, but I guess someone would be needed to do both, e.g. "{\"tmpl\": \"\{\{escape\}\}\", \"var\": \"{{replace}}\"}". IDK, maybe it is hard to implement, these are just my thoughts on it.
Anyway, it's doable through variables or unicode characters so thanks again for the quick response!
