axios - 发送表单数据和非表单数据 [英] axios - send form data AND non-form data

问题描述

我正在使用 axios 将数据发送到我的 nodejs/express 服务器.如果我想发送表单数据，我会执行以下操作(并且工作正常):

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
});

同样，上面的代码工作正常.这是它要去的 /someRoute 端点:

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'):
});

端点总是成功接收文件.到目前为止，一切都很好.

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

如果我想发送一些其他数据，比如日期，我可以这样发送(而且它也可以):

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'):
});

但是我如何同时发送formDate 和date 数据?我尝试了以下(但不起作用):

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
});

和端点:

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

这给了我一个 500 ERROR.

推荐答案

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

You can do the same thing you already did, just append the other data you also want to send to formData.. So formData.append(‘date’, date);
