mongodb中的游标使用
假设：
db.XXX.remove();
db.XXX.insert({"name":"BuleRiver1", "age":27});
db.XXX.insert({"name":"BuleRiver2", "age":23});
db.XXX.insert({"name":"BuleRiver3", "age":21});
find()返回一个游标：
var cursor = db.XXX.find();
while (cursor.hasNext()) {
obj = cursor.next();
print(obj.name);
}
使用游标的forEach():
cursor.forEach(function(x) {
print(x.name);
});
