nodejs的multiparty不解析任何上传的文件

标签: angularjs node.js sails.js multipart skipper

我尝试在后端使用sails.js在节点(multiparty)+ angular(angular-file-upload)上执行简单的上传文件。似乎前端正确地将文件发送到后端,但它出现后端没有收到任何信息或响应无效请求(不一致)。 form.parse部分用空字段和文件响应。我几乎被困在这里,谷歌搜索几小时找出多方的问题,但我找不到任何有用的信息。任何建议都会很感激

后端(具有多方的节点):

upload: function(req, res) {
    var multiparty = require('multiparty');
    var fs = require('fs');
    var util = require('util');

    var form = new multiparty.Form();

    form.parse(req, function(err, fields, file){
        if (err) {
            res.writeHead(400, {'content-type': 'text/plain'});
            res.end("invalid request: " + err.message);
            return;
        }
        console.log(file);
        res.writeHead(200, {'content-type': 'text/plain'});
        res.write('received fields:\n\n '+util.inspect(fields));
        res.write('\n\n');
        res.end('received files:\n\n '+util.inspect(file));
    });
 }

前端(带角度文件上传的角度):

$scope.upload = function () {
  //console.log($scope.file);

  if ($scope.file.data[0]){
    console.log("uploading file..");
    console.log($scope.file.data[0]);
    $upload.upload({
      url: 'api/v1.0/upload',
      method: 'POST',
      file: $scope.file.data[0]
    }).progress(function(evt){
      var progressPercentage = parseInt(100.0 * evt.loaded/evt.total);
      console.log('progress: ' + progressPercentage + '% ' + evt.config.data.name);
    }).success(function (data, status, headers, config){
      console.log('file ' + config.file.name + ' uploaded. Response: ' + data.status);
    });
  }

}

我改为在后端使用skipper,默认情况下带有sas js。在向后端发送post请求时,我需要将fileFormDataName指定为filename,我可以使用该名称在后端获取req.file('filename')。

将content-type设置为multipart:

$upload.upload({
      url: 'api/v1.0/upload',
      method: 'POST',
      data: { 'Content-Type': 'multipart/form-data' }, 
      file: $scope.file.data[0]
    }).progress(function(evt){
      var progressPercentage = parseInt(100.0 * evt.loaded/evt.total);
      console.log('progress: ' + progressPercentage + '% ' + evt.config.data.name);
    }).success(function (data, status, headers, config){
      console.log('file ' + config.file.name + ' uploaded. Response: ' + data.status);
    });
