如何将 API 发布为 object 而不是数组

Question

你好

如何将数据发布为 object

我试图制作这段代码，但它给了我错误

这是服务器的代码：

const projectData = [];

/* The rest of code is for setting up the server */


// GET route
app.get('/all', sendData);

function sendData(req, res) {
    res.send(projectData[projectData.length - 1]);
};

// POST route
app.post('/addWeather', addWeather);
//create add Weather function
function addWeather(req, res) {
    const temporary_object = {}

    temporary_object.date = req.body.date;

    temporary_object.temperature = req.body.temperature;

    temporary_object.content = req.body.content;

    projectData.push(temporary_object);

    res.send(projectData[projectData.length - 1]);

}

那么我该如何改变：

const projectData = [];

对此：

const projectData = {};

没有任何错误

你可以这样做：

function addWeather(req, res) {
    const objectToSend = {}
    objectToSend.date = req.body.date;
    objectToSend.temperature = req.body.temperature;
    objectToSend.content = req.body.content;
    res.send(objectToSend);
}
