axios - 发送表单数据和非表单数据

Question

I'm using axios to send data to my nodejs/express server. If I want to send form data, I do the following (and it works fine):

const formData = new FormData();
formData.append('nameOfFile', the_file);

axios({
    method: 'post',
    url: '/someRoute',
    data: formData
    headers: {
        'Content-Type': 'multipart/form-data'
        }
}).then(response => {
   // Do something with response
}).catch(err => {
   // Do something with err
});

Again, the above code works fine. Here is the /someRoute endpoint that it goes to:

app.post('/someRoute', (req, res) => {
    const uploadedFile = req.files.nameOfFile;
    res.send('success'):
});

The endpoint always successfully receives the file. So far, so good.

If I want to send some other piece of data, like a date , I can send it like so (and it also works):

const date = '2012-02-13';

axios({
    method: 'post',
    url: '/someRoute',
    data: date
})

app.post('/someRoute', (req, res) => {
    const date = req.body.date;
    res.send('success'):
});

But how do I send both the formDate and date data? I tried the following (but it doesn't work):

const formData = new FormData();
formData.append('nameOfFile', the_file);

axios({
    method: 'post',
    url: '/someRoute',
    data: {
        form: formData,
        date: '2012-02-13'
    },
    headers: {
        'Content-Type': 'multipart/form-data'
    }
}).then(response => {
   // Do something with response
}).catch(err => {
   // Do something with err
});

And the endpoint:

app.post('/someRoute', (req, res) => {
    const uploadedFile = req.files.nameOfFile;
    const date = req.body.date;
    res.send('success'):
});

This gives me a 500 ERROR .

你可以做你已经做过的同样的事情，只需将你也想发送的其他数据附加到 formData .. 所以 formData.append('date', date);
