Android 将图像上载到Node.js意外令牌

我想从android上传图片到node.js，接下来，我现在可以在网上查看图片，但总是上传图片

SyntaxError:意外标记�

如果我选择1.5mb文件，它会显示

错误：请求实体太大

我发现，似乎我必须将文件转换为JSON

但我想我已经使用这三个来加载大文件并将其转换为JSON

app.use(bodyParser.json());
app.use(bodyParser.json({limit: '5mb'}));
app.use(bodyParser.urlencoded({ extended: true }))

困在这里好几天了，请帮帮我

代码

路线代码

exports.upload = function(req, res) {
console.log(req.files.image.originalFilename);
console.log(req.files.image.path);
fs.readFile(req.files.image.path, function (err, data){
var dirname = "/Node/file-upload";
var newPath = dirname + "/uploads/" +   req.files.image.originalFilename;
fs.writeFile(newPath, data, function (err) {
  if(err){
    res.json({'response':"Error"});
  }else {
    res.json({'response':"Saved"});
  }
 });
});
};

错误

如果您使用的是像postman这样的扩展，请确保请求头中的内容类型是multipart/form data，而不是application/json。
