Question

mongodb — тестирование драйвера mongocxx c ++ с примером кода

Я пытаюсь соединить mongdb с драйвером mongocxx в моем примере кода C ++. Я добавил дополнительные включения, библиотеки и зависимости. Когда я его строю, это показывает следующую ошибку.

это полный код

#include "stdafx.h"#include <cstdint>
#include <iostream>
#include <vector>
#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
#include <mongocxx/uri.hpp>
#include <mongocxx/stdx.hpp>

using bsoncxx::builder::stream::close_array;
using bsoncxx::builder::stream::close_document;
using bsoncxx::builder::stream::document;
using bsoncxx::builder::stream::finalize;
using bsoncxx::builder::stream::open_array;
using bsoncxx::builder::stream::open_document;

int main() {
std::cout << "Hello, World!" << std::endl;

mongocxx::instance instance{}; // This should be done only once.
mongocxx::uri uri("mongodb://localhost:27017");
mongocxx::client client(uri);

return 0;
}

s — вывод ошибки.

Он говорит то, что говорит инициализирует ваш драйвер в первую очередь. если вы правильно скомпилировали драйвер, эти коды должны работать.

   #include <cstdlib>
#include <iostream>
#include <bsoncxx/builder/stream/document.hpp>
#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
#include <mongocxx/uri.hpp>using bsoncxx::builder::stream::close_document;
using bsoncxx::builder::stream::document;
using bsoncxx::builder::stream::finalize;
using bsoncxx::builder::stream::open_document;
mongocxx::instance instance{};// don't put inside main

int main() {
mongocxx::client conn{ mongocxx::uri{ "mongodb://localhost:27017" } };
auto coll = conn["test"]["coll"];
bsoncxx::builder::stream::document document{};
document << "Data" << "hello";
coll.insert_one(document.view());

return 0;
}
