使用multer时req.body始终为空

Question

尽管遵循了我遇到的所有文章，文档和资源，但我还是使用multer上传图像，每次req.body都是空的。下面是我的代码

const storage = multer.memoryStorage();

const upload = multer({ storage }).single(`image`);

  route.post("/upload", (request: Request, response: Response) => {
    upload(request, response, function (err) {
      if (err) {
        return response.end("Error uploading file.");
      }
      response.end("File is uploaded");
      console.log(request.body);
    });
  });
