Javascript 无法在节点js中使用angularjs http上载文件

我无法在angularjs中使用http上传文件/图像

这是我的控制器：

$scope.uploadFile = function(file, shipment_id, type, e) {
        if (file == null) {
            alert("Please enter image");
            return false;
        }

        var fileReader = new FileReader();
        fileReader.readAsDataURL(file);
        fileReader.onload = function(e) {

           // var base64encodedfile = e.target.result.match(/,(.*)$/)[1];
            var base64encodedfile = e.target.result;
            var data = {
                "file": {
                    "file":base64encodedfile,
                    "filename": file.name,
                     //"contentType": 'multipart/form-data',
                    //"filepath": "public://" + file.name,
                    "filemime": file.type
                }
            };
           console.log(e.target, 'dddd');
            var image_data = {
                'image': e.target.result,
                'shipment_id': shipment_id,
                'image_type': type,
               // "contentType": 'multipart/form-data',
            };
            console.log(image_data);

            //     var imageDATA = Base64.encode(image_data);
            $http({
                    method: 'POST',
                    url: store_config.BASE_URL + 'uploadImage/',

                    headers: {
                       // 'Content-Type': 'multipart/form-data',
                        'x-access-token': localStorage['token'],
                        'user_token': localStorage['user_token']
                    },
                    data: image_data
                })
                .success(function(data, status) {
                    console.log(data);
                })
                .error(function(d) {

                    console.log("not calling nope");
                });    
        }
    };

$scope.uploadFile = function(file,shipment_id,type,rowIndex,columnIndex) {
        if (file == null) {
            alert("Please enter image");
            return false;
          }

            $upload.upload({
                url: store_config.BASE_URL + 'uploadImage/',
                 method: 'POST',
                headers: {
                  'Content-Type': 'application/json',
                  'x-access-token': localStorage['token'],
                  'user_token': localStorage['user_token'],
                  'shipment_id': shipment_id,
                  'image_type': type
                },
                file: file,
              }).progress(function(evt) {
                console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
              }).success(function(data, status, headers, config) {
                $rootScope.orders[rowIndex].items[columnIndex].deliver = "ofd";
              });
   };

这是我上传文件到nodejs服务器的app.js代码：

apiRoutes.post('/uploadImage', function (req, res) {

console.log(req.body);
console.log("HHHHHHH");
request({
    url: api_url+'rms/seller_payment/unsettled/', //URL to hit
     headers: { //We can define headers too
        'Content-Type': 'multipart/form-data    ',
        'Access-Token': req.headers.user_token,
        'X-API-Version': '1.6'
    },
    method: 'POST', //Specify the method
    form: req.body
}, function(error, response, body){
    if(error) {
    console.log("error");
        console.log(error);
    } else {
    console.log("body");
     res.send(body);
       }
    });

});

当我尝试使用邮递员时，效果很好

请帮帮我

console.logreq.body

我已经解决了我的问题：

在HTML中

<div ng-class="item.invoice" ng-if="item.image_invoice_thumb == ''" ngf-select="uploadFile($file,item.shipment_id,'pod',rowIndex,columnIndex)" ng-model="file">Upload</div>

在app.js中

您必须安装模块：multer和fs

---

到底是什么不起作用？您遇到了什么错误？文件未上载到服务器。我没有收到任何错误console.logreq.body调用了吗？你到达你的路线了吗？好的，图像被上传到服务器上，因为你可以console.log它。你得到了{image:'数据：image/png；base64…是的，但是图像没有上传到服务器。你能告诉我是什么问题吗？

var multer  = require('multer');
var upload = multer({ dest: 'uploads/' });
var fs = require('fs');

apiRoutes.post('/uploadImage', upload.single('file'), function(req, res, body){

var fdd = { image: 
              { value: fs.createReadStream(req.file.path),
                options: { filename: req.file.originalname, contentType: null } },
             shipment_id: req.headers.shipment_id,
             image_type: req.headers.image_type };

request.post({url:api_url+'rms/seller_payment/unsettled/',
    headers: {
        'Content-Type': 'application/json',
        'Access-Token': req.headers.user_token
    }, 
    formData: fdd
    },
     function optionalCallback(err, httpResponse, body) {
  if (err) {
    return console.error('upload failed:', err);
  }
  fs.unlink(req.file.path, function (err) {
      if (err) throw err;
    });
  res.send(httpResponse);
});


});
