编译、测试 leveldb

准备工作

编译 leveldb

cd leveldb
make

测试

#include <iostream>
#include "leveldb/db.h"

using namespace std;
using namespace leveldb;

int main() {
DB *db ;
Options op;
op.create_if_missing = true;
Status s = DB::Open(op,"/tmp/testdb",&db);

if(s.ok()){
cout << "创建成功" << endl;
s = db->Put(WriteOptions(),"abcd","1234");
if(s.ok()){
cout << "插入数据成功" << endl;
string value;
s = db->Get(ReadOptions(),"abcd",&value);
if(s.ok()){
cout << "获取数据成功,value:" << value << endl;
}
else{
cout << "获取数据失败" << endl;
}
}
else{
cout << "插入数据失败" << endl;
}
}
else{
cout << "创建数据库失败" << endl;
}
delete db;
return 0;
}
