如何将二进制数据从C++传递到Node.js

#include <napi.h>

Napi::Value PassBinaryData(const Napi::CallbackInfo& info) {
  Napi::Env env = info.Env();

  // 获取传入的二进制数据
  Napi::Buffer<char> buffer = info[0].As<Napi::Buffer<char>>();
  char* data = buffer.Data();
  size_t length = buffer.Length();

  // 在这里处理二进制数据...

  // 返回结果给Node.js
  return Napi::String::New(env, "Binary data received and processed");
}

Napi::Object Init(Napi::Env env, Napi::Object exports) {
  exports.Set("passBinaryData", Napi::Function::New(env, PassBinaryData));
  return exports;
}

NODE_API_MODULE(addon, Init)

const addon = require('./addon');

// 创建一个Buffer来存储二进制数据
const binaryData = Buffer.from([0x01, 0x02, 0x03, 0x04]);

// 调用C++插件的接口函数来传递二进制数据
const result = addon.passBinaryData(binaryData);

console.log(result);  // 输出：Binary data received and processed
