c调用mongoDB

安装mongoDB-c-driver

安装必要软件

sudo apt-get install git autoconf automake libtool

下载mongoDB源码包

$ git clone https://github.com/mongodb/mongo-c-driver.git
$ cd mongo-c-driver
$ ./autogen.sh --with-libbson=bundled
$ make
$ sudo make install

将头文件以及库加入到系统路径中

export C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/include/libmongoc-1.0/:/usr/local/include/libbson-1.0/

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib

使用mongoDB-c-driver编程

初始化mongoc

非线程安全，只需调用一次

mongoc_init();

连接mongodb

const char *uristr = "mongodb://127.0.0.1/";
mongoc_client_t* m_pClient = mongoc_client_new(uristr);

获取collection

mongoc_collection_t * m_pCollection = mongoc_client_get_collection(m_pClient, "test_db", "test_collection");

插入记录

bson_error_t error;
bson_t *doc = bson_new();
BSON_APPEND_INT64(doc, "id", 1);
BSON_APPEND_INT64(doc, "field1", 0);
char msg[] = "test message";
BSON_APPEND_BINARY(doc, "field2", BSON_SUBTYPE_BINARY, msg, strlen(msg));

int r = mongoc_collection_insert(m_pCollection, MONGOC_INSERT_NONE, doc, NULL, &error);
if (r ==
