我有下一个代码(前端):
let imagesData = new FormData();
button.addEventListener('click', () => {
const data = {
id: 5,
name: 'five'
}
uploadDataToServer(imagesData);
})
const uploadDataToServer = (data) => {
axios.post('http://localhost:5000/upload', data)
.then((res) => console.log(res))
.catch((err) => console.log(err));
}
下一个后端部分:
app.post('/upload', upload.array('fileLoader', 5), (req, res, next) => {
const files = req.files;
if (!files) {
const error = new Error('Please upload a file');
error.httpStatusCode = 400;
return next(error);
}
res.send(files);
})
如何同时访问req.body中的对象数据和req.files中的图像?
最佳答案
您可以使用Formdata set-function向imagesData
添加新值。
let imagesData = new FormData();
button.addEventListener('click', () => {
/*
* Attention the set-funcetion sets a new value for an existing key
* or adds the key/value if it does not already exist
*/
imagesData.set('id', 5);
imagesData.set('name', 'five');
uploadDataToServer(imagesData);
})
const uploadDataToServer = (data) => {
axios.post('http://localhost:5000/upload', data)
.then((res) => console.log(res))
.catch((err) => console.log(err));
}
