Node.js 使用Cordova FileTransfer将文件上载到NodeJS时出错

我目前正在开发Phonegap应用程序，我希望用户能够将任何文件上传到我的NodeJS服务器

我在网上到处找，但我就是找不到任何有用的东西

以下是我用于Phonegap控制器的代码：

$scope.open = function()
{
        navigator.camera.getPicture(upload, 
        function(message) 
        {
            alert('get picture failed');
        }, 
        { 
            quality: 50,
            destinationType: navigator.camera.PictureSourceType.FILE_URI,
            sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY,
            mediaType: navigator.camera.MediaType.ALLMEDIA  
        });

    }

    var win = function (r) {
        $scope.log = "Code = " + r.responseCode;
        $scope.log2 = "Response = " + r.response;
        $scope.log3 = "Sent = " + r.bytesSent;
        $scope.$digest();  

    }

    var fail = function (error) {
        $scope.log = "An error has occurred: Code = " + error.code;
        $scope.log2 = "upload error source " + error.source;
        $scope.log3 = "upload error target " + error.target;
        $scope.$digest();  
    }

    function upload(fileURI)
    {
        $scope.log = fileURI;
        $scope.$digest();  

        var options = new FileUploadOptions();
        options.fileKey = "file";
        options.fileName = fileURI.substr(fileURI.lastIndexOf('/') + 1);
        options.mimeType = "text/plain";
        options.chunkedMode = false;

        var params = {};
        params.value1 = "test";
        params.value2 = "param";
        options.params = params;

        var ft = new FileTransfer();
        ft.upload(fileURI, "http://192.168.192.111:2999/upload", win, fail, options);
    }.

以下是NodeJS服务器的当前代码，您已经尝试了很多不同的方法，但都没有成功：

var express = require('express');
var http = require('http').Server(express);
var io = require('socket.io')(http);
var fs = require('fs');

var multer = require('multer');
var app = new express();


app.post('/upload', multer({dest: './uploads/'}).single('upl'), function(req, res)
{
  console.log(req.body);
  console.log(req.file);
})


http.listen(2999, function(){
  console.log('listening on *:2999');
});

在应用程序中，我经常会发现一些错误，比如没有定义FileUploadOptions等，但我通过将它们添加到cordova项目中来修复这些错误。 此外，我使用离子1，如果这对任何人都有帮助的话

尽管我选择了一个真实的文件，并且看到链接是正确的（类似于我的Android设备上的/storage/0/simulated/Downloads），但我还是不断地得到错误代码1（上传错误源）

此外，有时它也会给我错误3（上传目标源代码），我认为是某种服务器未找到的问题

是否有明显的问题我做错了，我该如何解决？有没有更方便的方法，因为我最终想把它链接到一个MySQL数据库

提前谢谢

我找到了我的答案（不久前，这是为那些在这篇文章中跌跌撞撞的人准备的）

您可以首先通过将服务器更改为来尝试JS是否工作。如果您看到上传出现在那里，说明服务器有问题

我的问题是，我根本没有让Apache通过防火墙，所以从我的PC以外的任何东西上传都会失败…

这是一个完整的代码表单字段，从ajax+jquery到nodejs，并保存到mysql DBCode，通常只应避免回答。我喜欢这样做的部分原因是，您应该能够理解解决方案，而不仅仅是学习如何剪切和粘贴代码。

var express=require('express');
var bodyParser=require('body-parser');
var formidable = require('formidable');
var util = require('util');
var app=express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
var path=require('path');
var mysql =require('mysql');
var fs=require('fs');

app.use('/public',express.static(path.join(__dirname, 'public')));

var connection = mysql.createConnection({
        host: 'localhost',
        user: 'root',
        password : '',
        port : 3306, //port mysql
        database:'xxxxx'
});
app.post('/data', function(req, res) {

 // create an incoming form object
  var form = new formidable.IncomingForm(),
        files = [],
        fields = [];
  // specify that we want to allow the user to upload multiple files in a single request
  form.multiples = true;

  // store all uploads in the /uploads directory
  form.uploadDir = path.join(__dirname, '/public/images/uploads');
  // every time a file has been uploaded successfully,
  // rename it to it's orignal name
  form.on('file', function(field, file) {
    if (path.extname(file.name)=='') {
        extension='.jpg';
    }
    else{
      extension=path.extname(file.name);
    }
    var oldpath = file.path;
    form.uploadDir = path.basename(file.name,extension).concat((Math.random()* 100),extension);               
    var newpath = './public/images/uploads/'+ path.basename(file.name,extension).concat((Math.random()* 100),extension);

    //fs.rename(file.path, path.join(form.uploadDir, file.name));
    fs.rename(oldpath, newpath);
  });
  form.on('field', function(field, value) {
      fields[field] = value;   
  });

  // log any errors that occur
  form.on('error', function(err) {
    console.log('An error has occured: \n' + err);
  });

  // once all the files have been uploaded, send a response to the client

//Call back at the end of the form.
form.on('end', function () {

    res.writeHead(200, {
        'content-type': 'text/plain'
    });
    res.write('received the data:\n\n');


   // console.log(fields.name+'-'+fields.nickname);
    var values={
          name:fields.name,
          nickname:fields.nickname,
          email:fields.email,
          password:fields.password,
          dob:fields.dob,
          gender:fields.gender,
          phoneno:fields.phone
      };

    connection.query('INSERT INTO users SET ?', values, function(err,req,res){
                        if(err){
                          console.log('Connection result error '+err);

                        }
                            else{
                        console.log('Success');     

                            }
                });

               res.end();  


});
  // parse the incoming request containing the form data
  form.parse(req);
});

//app.use(app.router);
app.listen(5000);
