read framer head magic 18516 != 2352, not match.

[adamgajzlerowicz]

I am trying to make a TypeScript server and a Go client work together, but they are not compatible.

I created a minimal repository where I tried to integrate them:

https://github.com/adamgajzlerowicz/trcp-cross-lang

What version of trpc-cmdline are you using?

trpc-group/trpc-cmdline version: v1.0.9

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

What did you do?

I am looking for a way to generate a TypeScript-based server from a proto file and a Golang client using the same proto file.

I created a proto file, and generated the backend code. Then I generated the Go code, but whenever I try to make a connection, I get an error.

What did you expect to see?

I expected to see data returned by the server.

What did you see instead?

Error:

Questions:

• Are the servers meant to be compatible in this way?
• Can you recommend how to make it work or suggest a compatible solution?

Many thanks.

Are you using https://github.com/trpc/trpc as the server? Although we have the same name, we are different projects. Our client cannot connect to their server. The error indicates that the server is running in HTTP protocol (magic 18516), and the trpc magic number required is 2352.

For those who are curious, 2352 is the decimal representation of 0x930. The number 18516, when converted to its hexadecimal representation and decoded to ASCII, is HT (which is the beginning two characters of an HTTP response).

Thank you so much for looking into this.
I was pulling my hair trying to get this those two to work together.
