I'm trying to connect grpc web client (browser) to nodejs @grpc/grpc-js server. I configured local certificates, serving web app from https and from alias host (https://sferadel.local) My nginx config (I'm running project via Nix devshell)
start-nginx.exec = let
nginxConf = pkgs.writeText "nginx.conf" ''
user root root;
pid ${DEVENV_STATE}/nginx/nginx.pid;
error_log ${DEVENV_STATE}/nginx/error.log debug;
daemon off;
events {
}
http {
access_log ${DEVENV_STATE}/nginx/access.log;
client_body_temp_path ${DEVENV_STATE}/nginx/;
proxy_temp_path ${DEVENV_STATE}/nginx/;
fastcgi_temp_path ${DEVENV_STATE}/nginx/;
scgi_temp_path ${DEVENV_STATE}/nginx/;
uwsgi_temp_path ${DEVENV_STATE}/nginx/;
server {
server_name sferadel.local;
listen 3001;
listen 443 ssl;
#listen 443 quic reuseport;
http2 on;
ssl_certificate ${DEVENV_STATE}/mkcert/sferadel.local+1.pem;
ssl_certificate_key ${DEVENV_STATE}/mkcert/sferadel.local+1-key.pem;
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';
add_header 'Access-Control-Allow-Headers' 'keep-alive,user-agent,cache-control,content-type,content-transfer-encoding,custom-header-1,x-accept-content-transfer-encoding,x-accept-response-streaming,x-user-agent,x-grpc-web,grpc-timeout';
if ($request_method != 'POST') {
return 404;
}
location / {
grpc_socket_keepalive on;
grpc_intercept_errors on;
grpc_set_header X-Real-IP $remote_addr;
grpc_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
grpc_pass grpc://localhost:3002;
}
}
}
'';
in "sudo ${pkgs.nginxQuic}/bin/nginx -c ${nginxConf}";
My grpc server:
const server = new grpc.Server({
// "grpc.enable_http_proxy": 1,
// "grpc.ssl_target_name_override": "sferadel.local",
// "grpc-node.tls_enable_trace": 1,
})
server.addService(...adaptService(EchoService, new Echo()))
server.bindAsync(
"0.0.0.0:3002",
grpc.ServerCredentials.createSsl(
fs.readFileSync("./.devenv/state/mkcert/rootCA.pem"),
[
{
cert_chain: fs.readFileSync("./.devenv/state/mkcert/sferadel.local+1.pem"),
private_key: fs.readFileSync("./.devenv/state/mkcert/sferadel.local+1-key.pem")
}
],
true
),
(err, port) => {
console.log(`Server bound on port: ${port}`)
server.start()
}
)
Client code:
const transport = new GrpcWebFetchTransport({ baseUrl: "https://sferadel.local:3001", format: "binary" })
new EchoServiceClient(transport).echo({ message: "Hello echo!" })
Nginx error I get:
2023/10/24 19:28:29 [info] 966188#966188: *7 client sent invalid method while reading client request line, client: 127.0.0.1, server: sferadel.local, request: "
What am I doing wrong?
