## How To Enable
|
||
|
||
Here's an example, to enable the grpc-transcode plugin to specified route:
|
||
|
||
* attention: the route's option `service_protocol` must be `grpc`
|
||
* 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/111 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"methods": ["GET"],
|
||
"uri": "/grpctest",
|
||
"service_protocol": "grpc",
|
||
"plugins": {
|
||
"grpc-transcode": {
|
||
"proto_id": "1",
|
||
"service": "helloworld.Greeter",
|
||
"method": "SayHello"
|
||
}
|
||
},
|
||
"upstream": {
|
||
"type": "roundrobin",
|
||
"nodes": {
|
||
"127.0.0.1:50051": 1
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
## Test Plugin
|
||
|
||
The above configuration proxy :
|
||
|
||
```shell
|
||
curl -i http://127.0.0.1:9080/grpctest?name=world
|
||
```
|
||
|
||
response:
|
||
|
||
```shell
|
||
HTTP/1.1 200 OK
|
||
Date: Fri, 16 Aug 2019 11:55:36 GMT
|
||
Content-Type: application/json
|
||
Transfer-Encoding: chunked
|
||
Connection: keep-alive
|
||
Server: APISIX web server
|
||
Proxy-Connection: keep-alive
|
||
|
||
{"message":"Hello world"}
|
||
```
|
||
|
||
This means that the proxying is working.
