我使用node.js與mongodb服務器進行通信。變量的發送和函數的輸出正在工作。在數據庫中寫作是沒有的,我找不到錯誤。這似乎是與插入一個問題,但我不能找到它.....在mongodb中寫入失敗/ node.js
mongo.js
index.js
/* POST home page. */
router.post('/create_movement', function(req, res) {
var tblname = req.body.tablename,
OutUser = req.body.out_user,
OutEmail = req.body.out_email,
OutDate = req.body.out_date;
mongo.InsertDocument(tblname, OutUser, OutEmail, OutDate);
res.send("succesfull");
});
節點.js文件控制檯
Example app listening at http://:::3005
Connection established to mongodb://localhost:27017/straff
function InsertDocument called
test234
POST /create_movement 500 317.042 ms - 954
出其餘客戶端的

我想你必須在你的** mongo.js **文件中實例化數據庫。 – theamateurdataanalyst
是的,就像theamateurdataanalyst建議的一樣......在這個範圍內似乎沒有定義「db」變量。也許在你的mongo.js的頂部你需要這樣的東西: var db = something; –
我切換到貓鼬,現在就開始工作。謝謝大家 – Piet
