将BSON数组添加到MongoDB 3.2文档并提取返回的值（MongoCXX 3.2）（C+；+；11） //文档我想添加数据并从C++中提取它 bsoncxx:：builder:：stream:：文档数据\u生成器， //我想尝试在我的文档中保存这个数组，因为我想稍后填充它 bsoncxx:：builder:：stream:：array mybsonarr； 对于（浮动i=0；i

用于将数组添加到流文档中，请使用

打开数组

：

    // The document I want to add data to and extract it back from c++
           bsoncxx::builder::stream::document data_builder,

           // I want to try and save this array in my document , as I want to  populate it later
           bsoncxx::builder::stream::array mybsonarr;
           for(float i = 0 ; i < 5 ; i = i + 0.1f){
             mybsonarr << i;
           }


// Now this line Throws an error 
data_builder << "_id" << 5 << "my_array" << &mybsonarr;

使用bsoncxx:：builder:：stream:：document；
使用bsoncxx:：builder:：stream:：open_数组；
使用bsoncxx:：builder:：stream:：close_数组；
使用bsoncxx:：builder:：stream:：finalize；
文件数据{}；
data_builder如何使用最新的mongocxx执行此操作？不再有stream:：open_数组。。。
  using bsoncxx::builder::stream::document;
  using bsoncxx::builder::stream::open_array;
  using bsoncxx::builder::stream::close_array;
  using bsoncxx::builder::stream::finalize;

  document data_builder{};
  data_builder << "_id" << 5;
  auto array_builder = data_builder << "my_array" << open_array;
  for (float i = 0 ; i < 5 ; i = i + 0.1f) {
    array_builder << i;
  }
  array_builder << close_array;
  bsoncxx::document::value doc = data_builder << finalize;
  std::cout << bsoncxx::to_json(doc) << std::endl;
