GCS 有一个受支持的 C++ 客户端库。来源在这里:https://github.com/googleapis/google-cloud-cpp

完整文档在这里:https://cloud.google.com/storage/docs/reference/libraries#client-libraries-install-cpp

下面是一个下载对象并计算行数的例子:

#include "google/cloud/storage/client.h"
#include <iostream>
namespace gcs = google::cloud::storage;

int countLines(std::string bucket_name, std::string object_name) {
  // Create aliases to make the code easier to read.
  namespace gcs = google::cloud::storage;

  // Create a client to communicate with Google Cloud Storage. This client
  // uses the default configuration for authentication and project id.
  google::cloud::StatusOr<gcs::Client> client =
      gcs::Client::CreateDefaultClient();
  if (!client) {
    std::cerr << "Failed to create Storage Client, status=" << client.status()
              << "\n";
    return 1;
  }

  gcs::ObjectReadStream stream = client.ReadObject(bucket_name, object_name);
  int count = 0;
  std::string line;
  while (std::getline(stream, line, '\n')) {
    ++count;
  }
  return count;
}
