File upload using guzzle client

$fileContent = File::get($filepath);
$request = $this->client->post($url, [
    'multipart' => [
        [
            'name' => 'upload',
            'contents' => $fileContent,
            'filename' => end(explode('/', $filepath)),
        ],
    ],
]);

@Yorki

Thanks for your reply but I am getting Fatal error like

Class 'QuickEmailVerification\Api\File' not found

How can I solve this??

Add use clause to your controller

use File;

@Yorki, Sorry for inconvenience, but i Added that Line but now error coming like

Class 'File' not found

Try

use Illuminate\Support\Facades\File;

@Yorki, getting same error

Class 'Illuminate\Support\Facades\File' not found

Are you even using Laravel framework to do this? If not then just use native php function

$fileContent = file_get_contents($filepath);

@Yorki, This is working but still file not getting uploaded.

Are you trying to upload file to an API, script or Laravel Controller? Is upload desired field name of uploaded file?

I am trying to upload file to API, but i am not using any form, without form need to upload file.

Is this API public? If so send me link to this endpoint documentation

No, this is not public API

@Yorki If i pass path of the file then i just need data like following with file upload and i am not using any form here

 [upload] => Array
        (
            [name] => testEmail.csv
            [type] => application/octet-stream
            [tmp_name] => /tmp/php5cbtni
            [error] => 0
            [size] => 61
        )

I don't know what are you trying to achieve exactly, can't you just use filesize() and mime_content_type()? This isn't even related to Laravel at all :)

@Yorki I am not using laravel, i am using only php All i just need to upload file without from using guzzle.
