ambassador 学习四 grpc 处理

实际上都是envoy 的功劳

基本环境安装参考相关文档即可

参考demo

• proto code

syntax = "proto3";

option java_multiple_files = true;
option java_package = "io.grpc.examples.helloworld";
option java_outer_classname = "HelloWorldProto";

package helloworld;

// The greeting service definition.
service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}

// The request message containing the user‘s name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings
message HelloReply {
  string message = 1;
}curl -v -H "x-ambassador-test-allow: probably" http://localhost:32190//qotm/quote/1
