1.github 直接下載我的代碼地址?
https://github.com/wblt/Node_ExpressDBConnect
2.創(chuàng)建數(shù)據(jù)庫 并且插入一條記錄
mongo//進(jìn)入數(shù)據(jù)庫
use hello-world//創(chuàng)建項目數(shù)據(jù)庫
db.createCollection("users")//創(chuàng)建一個集合琐馆，也就是表
db.users.insert({userid: "大兵哥", password: "123456"})//給users里添加一個文檔廓块，也就是一條記錄賬號admin哥遮，密碼123456
ok幔荒，現(xiàn)在檢查一下：
db.users.find()//如果看到你剛剛添加的文檔記錄悲雳，就ok咯
部分代碼?
