This is my .meshrc.yml file -

sources:

• name: Bluejestic
  handler:
  graphql:
  endpoint: http://localhost:3301/graphql
• name: Bluejestic-Message
  handler:
  graphql:
  endpoint: http://localhost:5000/graphql
  operationHeaders:
  Authorization: Bearer {context.headers['authorization']}

How I pass token without write Bearer in Authorization ?

[ardatan]

Let's think together here :)
Let's say you pass Authorization: Bearer FOO from the client, then what happens here?

operationHeaders:
-  Authorization: Bearer {context.headers['authorization']}
+ Authorization: Bearer Bearer FOO # Comes from the HTTP request

See there are two Bearers there. How do we prevent that?

+Authorization: Bearer {context.headers['authorization']}
-Authorization: "{context.headers['authorization']}"

@ardatan I have a follow up on this which is required in my case : SO I have to pass a static header (string value) in operation header which caller will not pass. SO I have to put that in .meshrc.yml file as a hadcoeded header value. I tried putting but its not going forward? Any solution/example?

I want to do something like this

[shadikkhan]

Passing static header under operationHeaders never works like content-type in very first sample example on this page.

There is no way to pass some static header either direct string or from env, it never goes into request.headers.

Please share a reproduction on CodeSandbox

[shinvey]

if you would like to forward request/response headers in specific scenario of nodejs application, you may try this header forward plugin.

[brampurnot]

Is there also a way to use a basic if/then statement like this:
operationHeaders:
user: "{context.req.internal ? context.req.internal : false}"

I tried it out but that doesn't seem to work. Any other alternative to achieve something like this?

[ardatan]

It is not possible right now
