我正在使用 Angular 和 ng2-file-upload。我收到一个错误:
{ Error: Unexpected field

code: 'LIMIT_UNEXPECTED_FILE',
field: 'file',
storageErrors: [] }
这是我的组件的 HTML:(该addEvent
函数调用uploadPicture
下面的函数。)
<form #f="ngForm"(ngSubmit)="addEvent(f.value)">
<input type="file" name="pic" ng2FileSelect [uploader]="uploader"/>
<button type="submit">Submit</button>
</form>
我的角组件:
uploadPicture() {
for (const item of this.uploader.queue) {
if (!item.isUploaded) {
item.upload();
}
}
}
和上传者:
public uploader: FileUploader = new FileUploader({url: this.imgUpldURL, authToken: `Bearer ${localStorage.getItem('token')}`});
还有我的 API 端点(我使用的是动态 ID,如果我提供没有动态 ID 的路径,它仍然不起作用):
const multer = require('multer');
router.post('/uploadEventImage', authCheck, (req, res) => {
const id = req.body.id;
const upload = multer({dest:
`../src/assets/images/news/${id}/`}).single('pic');
console.log('called')
upload(req, res, function (err) {
if (err) {
console.log(err);
return res.end(err.toString());
}
console.log('done');
res.end('File is uploaded');
});
});
这是我后端的所有 multer 配置。请求被成功接收。我在网上发现的大多数问题都是由于输入的名称属性与传入的不同.single('name')
,但是正如您所看到的,这并没有解决任何问题。
