 # Laravel-Proxy-Helper
-This is a basic helper for using laravel drivers as proxy servers. It allows you to forward exact requests to another server and return their response. Supports all methods, and also files.
+This is a basic helper for using laravel controllers as proxy servers. 
+It allows you to forward exact requests to another server and return their response. 
+Supports all methods, and also files.
+
+## What it does
+
+Its main function is to make requests from one point to another using laravel as a proxy.
+
+**Normal request:**
+
+Client ---> Server2
+
+``GET server2.test/api/avatar/color``
+
+**Request with this helper:**
+
+Client ---> Laravel ---> Server2
+
+``GET laravel.test/api/proxy/api/avatar/color``
+
+- Works with all GET, POST, PUT, HEAD, PATCH, DELETE methods
+- Works with all formats: JSON / Multipart / www-form-urlencoded
+- Supports files and any type of parameters supported by the original requests
+- Allows you to add headers, authorization, and custom options.
+- Returns the actual request (both content and status code)
+- Allows calls to be made dynamically (i.e., any request the customer may have)
+
+
+## How to add it
+Since it is not a package, it may seem more tedious, but it is very simple.
+
+### 1. Copy both files:
+`ProxyHelperFacade.php` y `ProxyHelper.php`
+in the folder you prefer from your laravel project, I've used: `App\Helpers`.
+**If you use a diferent folder, change the namespaces of both files.**
+
+### 2. Add the facade to your laravel project.
+Go to the file: `App\Providers\AppServiceProvider.php` and in the method `register()` adds the facade:
+```php
+$this->app->bind('ProxyHelper', function($app) {
+    return new ProxyHelper();
+});
+```
+remember that you need to import the class (not the one called facade) in `App\Providers\AppServiceProvider.php`
+```php
+use App\Helpers\ProxyHelper; //or your path
+```
+### 3. Import it wherever you're going to use it.
+Now you're gonna use the facade.
+```php
+use App\Helpers\ProxyHelperFacade;
+```
+to call him:
+```php
+ProxyHelperFacade::CreateProxy($request)
+```
+## How to use
+
+It's pretty basic, but you can modify it according to your needs.
+
+The constructor requires an object ``Illuminate\Http\Request``.
+
+From there you can forward the request to another server, or a specific url, or if you want to modify/add some options.
+
+I'll show you an example:
+
+#### 1. Create controller (or could be middleware)
+
+In my API drivers: ``routes\api.php`` (could be web, doesn't matter)
+
+I have created a route to receive any kind of request, and redirect it as to another host.
+
+```php
+Route::match(['get', 'post', 'head', 'patch', 'put', 'delete'] , 'proxy/{slug}', function(Request $request){
+
+
+})->where('slug', '([A-Za-z0-9\-\/]+)');
+```
+This route accepts any call (POST,GET..) and any route from /proxy, i.e. ``my.laravel.test/api/proxy/*``
+
+So, when you want to call my ``server2``, I'll do it this way:
+
+Suppose I want to call GET ``my.server2.test/api/avatar/color``, I'll do it like this: 
+
+GET ``my.laravel.test/proxy/api/avatar/color``
+
+#### 2. Use ProxyHelper (Basic)
+
+I will continue to show the example inside the controller we have created.
+
+```php
+Route::match(['get', 'post', 'head', 'patch', 'put', 'delete'] , 'proxy/{slug}', function(Request $request){
+
+    // To redirect the request to a different host, the first parameter will be the host.
+    // the second, will be the current path that we want to ignore, it must be the url of the controller (api/proxy)
+    //so we're telling you that the new url will be:
+    // (host) http://my.server2.test + (deleted)[api/proxy] + ({slug}) /api/avatar/color
+    return ProxyHelperFacade::CreateProxy($request)->toHost('http://my.server2.test','api/proxy');
+    
+    //other way is to tell him the url directly.
+    return ProxyHelperFacade::CreateProxy($request)->toUrl('http://my.server2.test/api/avatar/color');
+    
+    // this second way will no longer be dynamic.
+    
+
+})->where('slug', '([A-Za-z0-9\-\/]+)');
+```
+#### 3. Options
+
+Once we've seen how to make it dynamic or static, there are a few options:
+
+```php
+Route::match(['get', 'post', 'head', 'patch', 'put', 'delete'] , 'proxy/{slug}', function(Request $request){
+
+    return ProxyHelperFacade::CreateProxy($request)
+            // add a header before sending the request
+            ->withHeaders(['x-custom' => 'customHeader'])
+            // add a Bearer token (this is useful for the client not to have the token, and from the intermediary proxy we add it.
+            ->withToken('eyJhbGcLPbNA...')
+            //Maintain the query of the url.
+            ->preserveQuery(true)
+            ->toHost('http://my.server2.test','api/proxy');
+
+})->where('slug', '([A-Za-z0-9\-\/]+)');
+```
+some more:
+
+``->withBasicAuth('user','pass')``,
+
+``->withDigestAuth('user','pass')``,
+
+``->withMethod('POST'`)``,
+
+And that's it, I hope it helps you, if you want to add more things like custom cookies, follow the same dynamics of the file, it's very simple.
