我正在开发一个restful Api nodejs,我的第一步是使用数据结构,所有过程都很好,现在我想使用postgresql实现具有持久性的crud,我被困在post端点上,我的查询没有尽管我努力通过。
获取端点运行良好,所有必需品都已安装,只是在后端点上被阻止。在我的代码下面找到
router.post('/', function(req, res, next) {
pool.connect(function (err, client, done) {
if (err) {
console.log("Can not connect to the DB" + err);
}
client.query('INSERT INTO users(firstname, lastname, othername, email,
phoneNumber, username, registered, isAdmin) VALUES($1, $2, $3, $4, 5$,
6$, 7$, $8) returning *',
[req.body.firstname, req.body.lastname, req.body.othername,
req.body.email, req.body.phoneNumber, req.body.username,
req.body.registered, req.body.isAdmin ],
function (err, result) {
done();
if (err) {
console.log(err);
res.status(400).json({
status : 400,
error : err
});
}
res.status(200).json({
status : 200
});
});
});
我没有在我的数据库中插入数据,而是收到以下错误
{
"status": 400,
"error": {
"name": "error",
"length": 106,
"severity": "ERREUR",
"code": "42601",
"position": "126",
"file": "scan.l",
"line": "1134",
"routine": "scanner_yyerror"
}
}
在 Postman 上运行时,console.log(err) 显示了这个
{ error: erreur de syntaxe sur ou près de « $ »
