scalapb生成的proto中的未知字段

我对scalapb和protobuf不熟悉。

我正在尝试为scalapb的生成器创建单元测试。我已经生成了proto文件,并尝试在测试中使用它们。

我有一个原始文件:

syntax = "proto3";

package hellogrpc.calc;

import "google/api/annotations.proto";

option (scalapb.options) = {
  flat_package: true
};

service CalcService {

    rpc CalcSum (SumRequest) returns (CalcResponse) {
        option (google.api.http) = {
          post: "/calcService/sum"
          body: "*"
        };
    }

}

有一个方法CalcSum被注释

以及相应生成的原型文件:

// Generated by the Scala Plugin for the Protocol Buffer Compiler.
// Do not edit!
//
// Protofile syntax: PROTO3

package hellogrpc.calc



object CalcServiceProto extends _root_.com.trueaccord.scalapb.GeneratedFileObject {
  lazy val dependencies: Seq[_root_.com.trueaccord.scalapb.GeneratedFileObject] = Seq(
    com.trueaccord.scalapb.scalapb.ScalapbProto,
    com.google.api.annotations.AnnotationsProto
  )
  lazy val messagesCompanions: Seq[_root_.com.trueaccord.scalapb.GeneratedMessageCompanion[_]] = Seq(
    hellogrpc.calc.SumRequest,
    hellogrpc.calc.CalcResponse
  )
  private lazy val ProtoBytes: Array[Byte] =
      com.trueaccord.scalapb.Encoding.fromBase64(scala.collection.Seq(

  lazy val scalaDescriptor: _root_.scalapb.descriptors.FileDescriptor = {
    val scalaProto = com.google.protobuf.descriptor.FileDescriptorProto.parseFrom(ProtoBytes)
    _root_.scalapb.descriptors.FileDescriptor.buildFrom(scalaProto, dependencies.map(_.scalaDescriptor))
  }
  lazy val javaDescriptor: com.google.protobuf.Descriptors.FileDescriptor = {
    val javaProto = com.google.protobuf.DescriptorProtos.FileDescriptorProto.parseFrom(ProtoBytes)
    com.google.protobuf.Descriptors.FileDescriptor.buildFrom(javaProto, Array(
      com.trueaccord.scalapb.scalapb.ScalapbProto.javaDescriptor,
      com.google.api.annotations.AnnotationsProto.javaDescriptor
    ))
  }
  @deprecated("Use javaDescriptor instead. In a future version this will refer to scalaDescriptor.", "ScalaPB 0.5.47")
  def de
```scriptor: com.google.protobuf.Descriptors.FileDescriptor = javaDescriptor
}

我检查CalcServiceProto。intellj idea中的javaDescriptor:

方法描述符具有以下原型定义:

name: "CalcSum"
input_type: ".hellogrpc.calc.SumRequest"
output_type: ".hellogrpc.calc.CalcResponse"
options {
  72295728: "\"\020/calcService/sum:\001*"
}

但发电机工作正常!我调试生成器,在生成器上切换断点,方法CalcSum有以下原型定义:

name: "CalcSum"
input_type: ".hellogrpc.calc.SumRequest"
output_type: ".hellogrpc.calc.CalcResponse"
options {
  [google.api.http] {
    post: "/calcService/sum"
    body: "*"
  }
}

可能是因为我没有像generator那样注册扩展,所以这种方式的工作方式有所不同。

我希望以任何方式通过此测试:

  val s = CalcServiceProto.javaDescriptor.getServices.get(0)

  val m = s.getMethods.get(0)

  m.getOptions.getExtension(AnnotationsProto.http).getPost shouldBe "/calcService/sum"
