Question

我想将图像从android上传到node.js，关注this one，我现在可以从网上查看图片，但始终上传图片

SyntaxError：意外的令牌�

如果我选择1.5mb文件则显示

错误：请求实体太大

我发现this，似乎我必须将文件转换为JSON

但我虽然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 }))

在这里坚持了好几天，请帮忙

码

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var http = require('http');
app.use(bodyParser.json());
app.use(bodyParser.json({limit: '5mb'}));
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies.
songs = require('./routes/route');
var jsonParser = bodyParser.json();
app.listen(3000, function () {
console.log('Example app listening on port 3000!');
});
app.get('/', function (req, res) {
  res.send('Hello World!');
});

app.get('/songs',songs.findAll);
app.get('/findById/:id',songs.findById);
app.post('/songs',songs.addSong);
app.put('/songs/:id',songs.updateSong);
app.delete('/songs/:id',songs.deleteSong);
app.post('/upload',songs.updateSong);
app.get('/upload/:file',songs.viewByFile);

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"});
  }
 });
});
};

如果您使用像邮递员这样的扩展程序，请确保Content-Type是多部分/表单数据，而不是请求标头中的application / json。
