Laravel Uploading Files Via API Using Postman Example

Follow the below given following steps and upload file via API using postman with validation in laravel app:

• Step 1: Install Laravel New App
• Step 2: Add Database Credentials
• Step 3: Generate Migration & Model
• Step 4: Create Routes For File
• Step 5: Generate Controller by Artisan
• Step 6: Run Development Server
• Step 7: Laravel Upload File Via Api Using PostMan

Step 1: Install Laravel New App

First of all, open your terminal and run the following command to install or download laravel fresh application setup for uploading files via laravel api:

composer create-project --prefer-dist laravel/laravel Blog

Step 2: Add Database Credentials

Next, Navigate to your downloaded laravel app root directory and open .env file. Then add your database details in .env file, as follow:

 DB_CONNECTION=mysql
 DB_HOST=127.0.0.1
 DB_PORT=3306
 DB_DATABASE=here your database name here
 DB_USERNAME=here database username here
 DB_PASSWORD=here database password here

Step 3: Generate Migration & Model

In this step, open a command prompt and run the following command:

php artisan make:model Documents -m

This command will create one model name file and as well as one migration file for the Documents table.

Then Navigate to database/migrations folder and open create_documents_table.php. Then update the following code into create_documents_table.php:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreatedocumentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('documents', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->integer('user_id');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('documents');
    }
}

After that, run the following command to migrate the table into your select database:

php artisan migrate

Step 4: Create Route For File

In this step, Navigate to the app/routes folder and open api.php file. Then update the following routes into your api.php file:

 Route::prefix('v1')->group(function(){
  Route::post('store-file', 'DocumentController@store');
 });

Step 5: Generate Controller by Artisan

In this step, open your terminal and run the following command:

php artisan make:controller Api\DocumentController

Note that, This command will create a controller named DocumentController.php file.

Now app/controllers/Api folder and open DocumentController.php. Then update the following file uploading methods into your DocumentController.php file:

<?php

namespace App\Http\Controllers\Api;

use Illuminate\Http\Request;
use Validator,Redirect,Response,File;
use App\Document;
use Validator;
class DocumentController extends Controller
{

    public function store(Request $request)
    {

       $validator = Validator::make($request->all(),
              [
              'user_id' => 'required',
              'file' => 'required|mimes:doc,docx,pdf,txt|max:2048',
             ]);

	if ($validator->fails()) {
            return response()->json(['error'=>$validator->errors()], 401);
         }


        if ($files = $request->file('file')) {

            //store file into document folder
            $file = $request->file->store('public/documents');

            //store your file into database
            $document = new Document();
            $document->title = $file;
            $document->user_id = $request->user_id;
            $document->save();

            return response()->json([
                "success" => true,
                "message" => "File successfully uploaded",
                "file" => $file
            ]);

        }


    }
}

If you want to upload images via api instead of files in laravel. So you can change in validation rules on the controller file, as follow:

'file'  => 'required|mimes:png,jpg|max:2048',

Step 6: Run Development Server

In this step, run the following command to start the development server:

 php artisan serve

Step 7: Laravel Upload File Via Api Using PostMan
