我正在尝试通过发送一个整数,response.send()但我不断收到此错误
express deprecated res.send(status): Use res.sendStatus(status) instead
表示不推荐使用的 res.send(status):使用 res.sendStatus(status) 代替
I am not sending a Status, my code is
我没有发送状态,我的代码是
app.get('/runSyncTest' , function(request, response){
var nodes = request.query.nodes;
var edges = request.query.edges;
if (edges == "" ){
edges = []
}
userStory.userStory(nodes,edges);
connection.query('SELECT MAX(id) as id FROM report ', function(err,results, fields) {
idTest = results[0].id
response.send (idTest)
});
});

You could try this:
你可以试试这个:
res.status(200).send((results[0].id).toString());
Guys are right - it doesn't allow numbers. Prooflink: http://expressjs.com/4x/api.html#res.send
伙计们是对的 - 它不允许数字。校对链接:http://expressjs.com/4x/api.html#res.send

This is because you are sending numeric value in the res.send.
这是因为您在 res.send 中发送数值。
You could send a json object or convert it to string.
您可以发送一个 json 对象或将其转换为字符串。

(as mentioned in the comments already)
(如评论中所述)
The body parameter can be a Buffer object, a String, an object, or an Array.
body 参数可以是一个 Buffer 对象、一个字符串、一个对象或一个数组。
So integers aren't directly supported and need to be converted to one of those types first. For instance:
因此,不直接支持整数,需要先将其转换为其中一种类型。例如:
response.send(String(idTest));

Use like this,
像这样使用,
res.status(404).send('Page Not found');

As long as you're not sending String or Object/Array data you get an error. Solution convert your data to string:
只要您不发送字符串或对象/数组数据,就会出现错误。解决方案将您的数据转换为字符串:
app.get('/runSyncTest', function(req, res) {
var number = 5000;
res.send((number).toString()); //Number is converted with toString()
});

Its deprecated Express 5 no longer supports the signature like-
其已弃用的 Express 5 不再支持这样的签名-
res.json(200, {
result: result
});
Instead, use a method like this, means you only need to change the format of sending responses.
相反,使用这样的方法,意味着您只需要更改发送响应的格式。
res.status(status).json(obj)
Example -
例子 -
res.status(200).json({'success' : true, 'result': 'result'})
