Question

当我尝试使用Mysql，AWS ElasticBeanstalk Nginx服务器插入一些文本时，

有时会出现502 Bad Gateway的错误消息。

只有插入案例是错误的（选择，更新，删除工作正常。）

如果我尝试在localhost中插入，它的效果非常好。

<form action="/finance" method="post">
	<div class="input-field col l12">
		<input name="consult_name" type="text">
		<input type="submit" value="send">	
	</div>
</form>

router.post('/finance', function(req, res, next) {
	var consult_name = req.body.consult_name;
	console.log(consult_name);
	
	
	var sets = {consult_name : consult_name};
	
	mysql.insert('insert into cider.cid_finance set ?', sets,  function (err, data){

	res.redirect('/finance');
	});
});

您的sql语法错误。错误消息清楚地表明mysql语法是问题所在。

试试这个：

mysql.insert('insert into cider.cid_finance set consult_name = ?', consult_name,  function (err, data){

Nodejs / Nginx服务器（AWS）/ Mysql / insert 502 Bad Gateway错误
