Uploading Files with Additional Information in Angular

Uploading Files with Additional Information in Angular

I am currently utilizing the Angular-file-upload library to upload files to an API. This is how I'm approaching it:

var uploadFile = function (file) {
    return $upload.upload({
        url: '/api/place/logo',
        data: {place_id: 1, token: <some_token>},
        file: file
    });
};

All the parameters appear to be properly configured. The API requires the inclusion of a token for authentication purposes. However, despite setting the necessary data, the API consistently returns a BadRequest error and does not seem to receive the token or the place_id sent by the client.

What could potentially be causing this issue?

Give this a shot.

Inside your Angular controller:

.controller('uploadCtrl', function ($scope, FileUploader) {
    $scope.uploader = new FileUploader({
        url: "./api/file/upload",
        formData: [
            { "param1": "value1" },
            { "param2": "value2" }
        ]
    });
});

On the server side (in your FileController's upload method):

var provider = GetMultipartProvider();
var result = await Request.Content.ReadAsMultipartAsync(provider);

var param1 = result.FormData.Get("param1");
var param2 = result.FormData.Get("param2");

Are you currently utilizing a Bearer token for authentication? I encountered a similar issue while using the https://github.com/nervgh/angular-file-upload. It turned out that the file upload was being done through AJAX instead of $http, causing the authorization interceptor service to fail in injecting the token into outgoing requests from my Angular website.

Depending on the functionality of your library, you might be facing a comparable problem. In such cases, you need to set the token as the 'Authorization' header. Here's an example (where authData is retrieved from localStorage after previous authorization by the token provider):

tokenHeader = 'Bearer ' + authData.token;
var uploader = $scope.uploader = new FileUploader({
    headers: { "Authorization": tokenHeader },
    url: _uploadUrl,
    withCredentials: true
 });

This is my preferred method:

const authHeader = $http.defaults.headers.common.Authorization;

const fileUploader = $scope.uploader = new FileUploader({
    url: '/api/WS_Books/PostBooks',
    autoUpload: true,
    headers: { "Authorization": authHeader },
    withCredentials: true
});

Injecting a JWT token using the onBeforeUploadItem method is a secure way to handle authentication.

    uploader.onBeforeUploadItem = function (item) {
      item.headers = {
      'Authorization': 'Bearer ' + localStorage.getItem('token_name')
       };
    };

This method worked successfully for me when working with PHP.

To pass data values to PHP, you can utilize the formData property as shown below:

app.controller ('FileUploadCtrl', ['$ scope', 'FileUploader', 
function ($ scope, FileUploader) {
var uploader = $ scope.uploader = new FileUploader ({
    url: '.myapi / mycontrollers / myuploadfile.php',
    formData: [{
             data1: 'value1',
             data2: 'value2',
             dataN: 'valueN'
           }]
});

When handling this in PHP, you can retrieve the information from formData using $ _REQUEST like so:

$myValue1 = $_REQUEST ['data1'];
$myValue2 = $_REQUEST ['data2'];
$myValue3 = $_REQUEST ['dataN'];
