Angularjs 文件上传说此请求没有可用的响应数据

Question

我使用下面的代码将图片和用户名上传到服务器。它工作正常。

现在我想return控制台中的用户名和文件名，但它显示此请求没有可用的响应数据。我曾尝试使用 successcallback() 函数，但仍然没有成功。看来问题出在 successcallback()。谁能帮我解决这个问题。

        file.upload = Upload.upload({
      method: 'post',
          url: 'image.php',
         data: {username: $scope.username, file: file},


        }).then(function successCallback(response) {

    alert(response.data[0].username);
    alert(response.data[0].file);
    console.log(response.data[0].username);
    });

下面是完整代码

    //inject angular file upload directives and services.
    var app = angular.module('fileUpload', ['ngFileUpload']);

    app.controller('MyCtrl', ['$scope', 'Upload', '$timeout','$http', function ($scope, Upload, $timeout, $http) {
        $scope.uploadPic = function(file) {
        file.upload = Upload.upload({
          url: 'upload.php',
          data: {username: $scope.username, file: file},
        });

        file.upload.then(function (response) {
          $timeout(function () {
            file.result = response.data;
console.log(response.data[0].username);
          });
        }, function (response) {
          if (response.status > 0)
            $scope.errorMsg = response.status + ': ' + response.data;
        }, function (evt) {
          // Math.min is to fix IE which reports 200% sometimes
          file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
        });
        }
    }]);

image.php

<?php
error_reporting(0);
$data = json_decode(file_get_contents("php://input"));
 $username = strip_tags($data->username);


$return_arr[] = array("username"=>$username);
 echo json_encode($return_arr);
exit();

Answer 1

上面post中提到的问题已经解决。

我将表单参数用户名发送为 json_decode()

$data = json_decode(file_get_contents("php://input"));
 $username = strip_tags($data->username);

将所有内容作为 post 参数发送解决了我的问题，如下例

$username = $_POST['username'];

谢谢
