如何使用Angular 4上传图片？
<input type="file" (change)="uplod($event)"/>
Spring代码：
@RequestMapping(value="/Etablissement/upload", method=RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<Object> uploadFile(@RequestParam("file") MultipartFile file) throws IOException {
File convertFile = new File("C:/Users/acer/reservationF/reservation/reservation/image"+file.getOriginalFilename());
convertFile.createNewFile();
FileOutputStream fout = new FileOutputStream(convertFile);
fout.write(file.getBytes());
fout.close();
return new ResponseEntity<>("File is uploaded successfully", HttpStatus.OK);
}
