cocoscreator 3.8.2，生成命令：
set PROTOC_GEN_TS_PATH="CD/node_modules/.bin/protoc-gen-ts.cmd"
set OUT_DIR=“assets/Script/proto”
protoc.exe -I=proto --plugin=protoc-gen-ts=PROTOC_GEN_TS_PATH --ts_out=OUT_DIR proto/*.proto
protoc.exe的版本是"protoc-3.15.8-win64"。
test.proto:
syntax = “proto3”;
message TestInfo {
int32 accountType = 1;
}
assets/Script/proto/test_pb.d.ts:
// package:
// file: test.proto
import * as jspb from “google-protobuf”;
export class TestInfo extends jspb.Message {
getAccounttype(): number;
setAccounttype(value: number): void;
serializeBinary(): Uint8Array;
toObject(includeInstance?: boolean): TestInfo.AsObject;
static toObject(includeInstance: boolean, msg: TestInfo): TestInfo.AsObject;
static extensions: {[key: number]: jspb.ExtensionFieldInfo<jspb.Message>};
static extensionsBinary: {[key: number]: jspb.ExtensionFieldBinaryInfo<jspb.Message>};
static serializeBinaryToWriter(message: TestInfo, writer: jspb.BinaryWriter): void;
static deserializeBinary(bytes: Uint8Array): TestInfo;
static deserializeBinaryFromReader(message: TestInfo, reader: jspb.BinaryReader): TestInfo;
}
export namespace TestInfo {
export type AsObject = {
accounttype: number,
}
}
使用处的代码：
import { IProtocolHelper, NetData } from ‘./NetInterface’;
//import { TestInfo } from ‘…/proto/test.d’;
import { TestInfo } from ‘…/proto/test_pb.d’;
export class ProtobufProtocolHelper implements IProtocolHelper {
private typeMessageParser: Map<number, any> = new Map();
constructor() {
console.log('constructor');
let testInfo = new TestInfo();
//testInfo.accountType = 1;
console.log(testInfo);
testInfo.setAccounttype(1);
console.log(JSON.stringify(testInfo));
}
