通过角度http请求发布文件

Question

我正在使用angularjs，我正在尝试将图片与请求正文中的其他数据一起上传到django后端服务器。

我一直收到来自服务器的错误，告诉我我发送的图片不是文件。 （假设后端没有问题）

我尝试使用ng-file-upload（ https://github.com/danialfarid/ng-file-upload ）来获取文件，然后通过angular本身发送它。 （注意：我需要将其他数据与图片一起发送）所以我想将文件存储在变量中并将其传递到请求体中，如下所示：

<form name="form">
<div class="button" ngf-select ng-model="file" name="file" ngf-resize="{width: 100, height: 100}">Select</div>
<button type="submit" ng-click="submit()">submit</button>
</form>

由于文件存储在$ scope.file中，我尝试在http请求中使用它：

$http({
          'method': "PUT",
          'url': "api/candidate-profiles/" + id,
          'data':data
})

数据是：

{"id": $scope.id,
"name": $scope.name,
"avatar":$scope.file}

我从后端收到验证错误，指出该头像不是文件。 有帮助吗？

HTML

<div ng-controller="formCtrl">
            <form  name="userForm"  class="well form-search"   >

                <input type="text" ng-model="name" class="input-medium search-query" placeholder="Name" required >
                <input type="email" ng-model="email" class="input-medium search-query" placeholder="Email" required >
                <input type="text" ng-model="message" class="input-medium search-query" placeholder="Message" required >
                <button type="submit" class="btn" ng-click="formsubmit(userForm.$valid)"  ng-disabled="userForm.$invalid">Submit </button>

            </form>
            <pre ng-model="result">
                {{result}}
            </pre>
        </div>

jsfile

var app = angular.module('formExample', []);

app.controller("formCtrl", ['$scope', '$http', function($scope, $http) {
        $scope.url = 'submit.php';

        $scope.formsubmit = function(isValid) {


            if (isValid) {


                $http.post($scope.url, {"name": $scope.name, "email": $scope.email, "message": $scope.message}).
                        success(function(data, status) {
                            console.log(data);
                            $scope.status = status;
                            $scope.data = data;
                            $scope.result = data; // Show result from server in our <pre></pre> element
                        })
            }else{

                  alert('Form is not valid');
            }


        } }]);

我想你应该阅读文档，并看到像一些样品本

app.controller('MyCtrl', ['$scope', 'Upload', '$timeout', function ($scope, Upload, $timeout) {
    $scope.uploadPic = function(file) {
    file.upload = Upload.upload({
        url: 'https://angular-file-upload-cors-srv.appspot.com/upload',
        data: {username: $scope.username, file: file},
    });

    file.upload.then(function (response) {
        $timeout(function () {
            file.result = response.data;
        });
    }, 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));
    });
    }
}]);
