如何在本机node-mongo-native驱动程序中执行MongoDB查询? [英] How to execute a MongoDB query in the native node-mongo-native driver?

问题描述

有什么方法可以将像db.things.find()这样的MongoDB查询直接传递给 Mongo C驱动程序或Javascript驱动程序 node-mongo-native 进行查询?

is there any way I can pass a MongoDB query like db.things.find() directly to the Mongo C Driver or the Javascript driver node-mongo-native to make a query?

我想知道本机驱动程序是否能够评估查询并返回结果.

I am wondering the native driver is able to evaluate the query and return the result.

该怎么做?

谢谢！

推荐答案

mongo.h 似乎是您要搜索的内容.

The method mongo_simple_str_command(…) in mongo.h seems to be what you are searching for.

mongo_simple_str_command(conn, db, "$eval", "db.foo.find()", out);

我在这里找到了一个用法示例: https://github.com/mongodb/mongo-c-driver/blob/master/test/platform/linux/timeouts.c

I found an usage example here: https://github.com/mongodb/mongo-c-driver/blob/master/test/platform/linux/timeouts.c
