proxying gRPC traffic:
|
||
gRPC client -> APISIX -> gRPC server
|
||
|
||
### Parameters
|
||
|
||
* `service_protocol`: the route's option `service_protocol` must be `grpc`
|
||
* `uri`: format likes /service/method , Example：/helloworld.Greeter/SayHello
|
||
|
||
|
||
|
||
### Example
|
||
|
||
#### create proxying gRPC route
|
||
|
||
Here's an example, to proxying gRPC service by specified route:
|
||
|
||
* attention: the route's option `service_protocol` must be `grpc`
|
||
* attention: APISIX use TLS‑encrypted HTTP/2 to expose gRPC service, so need to [config SSL certificate](https.md)
|
||
* the grpc server example：[grpc_server_example](https://github.com/iresty/grpc_server_example)
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -d '
|
||
{
|
||
"methods": ["POST", "GET"],
|
||
"uri": "/helloworld.Greeter/SayHello",
|
||
"service_protocol": "grpc",
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:50051": 1
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
|
||
#### testing
|
||
|
||
Invoking the route created before：
|
||
|
||
```shell
|
||
$ grpcurl -insecure -import-path /pathtoprotos -proto helloworld.proto -d '{"name":"apisix"}' 127.0.0.1:9443 helloworld.Greeter.SayHello
|
||
{
|
||
"message": "Hello apisix"
|
||
}
|
||
```
|
||
|
||
This means that the proxying is working.
