HTTP(s) -> APISIX -> gRPC server
content
: .proto
文件的内容路径中最后的数字,会被用作 proto 的 id 做唯一标识,比如下面示例的 proto id
是 1
:
curl http://127.0.0.1:9080/apisix/admin/proto/1 -X PUT -d ' { "content" : "syntax = \"proto3\"; package helloworld; service Greeter { rpc SayHello (HelloRequest) returns (HelloReply) {} } message HelloRequest { string name = 1; } message HelloReply { string message = 1; }" }'
proto_id
: .proto
内容的id.service
: grpc服务名.method
: grpc服务中要调用的方法名.在指定 route 中,代理 grpc 服务接口:
service_protocal
必须设置为 grpc
curl http://127.0.0.1:9080/apisix/admin/routes/111 -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 } } }'
访问上面配置的 route:
$ curl -i http://127.0.0.1:9080/grpctest?name=world 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"}
这表示已成功代理。
