编辑: Buzz的更新时间已超过一年,现在推荐使用Guzzle,请参阅Mohammed Safeer的回答.
我使用Buzz包来发出API请求.
您可以通过将此包添加到文件中的require部分来添加此包composer.json.
{
require: {
"kriswallsmith/buzz": "dev-master"
}
}
然后运行composer update以安装它.
然后在Laravel中,您可以将其包装在一个类(可能是类似于存储库的类)中,该类处理API请求并返回您的应用程序要使用的数据.
<?php namespace My\App\Service;
class SomeApi {
public function __construct($buzz)
{
$this->client = $buzz;
}
public function getAllWidgets()
{
$data = $this->client->get('http://api.example.com/all.json');
// Do things with data, etc etc
}
}
注意:这是伪代码.您需要创建一个适合您需求的类,并执行您想要/需要的任何花哨依赖注入或代码体系结构.
正如@Netbulae所指出的,存储库可能对您有所帮助.他链接的文章是一个很好的起点.本文与您的代码之间的唯一区别是,您不是使用Eloquent模型从数据库获取数据,而是发出API请求并将结果转换为应用程序可以使用的一组数组/对象使用(基本上,只是数据存储是不同的,这是首先打扰存储库类的好处之一).

我们可以在Laravel中使用Guzzle包,它是一个发送HTTP请求的PHP HTTP客户端.
你可以通过作曲家安装Guzzle
composer require guzzlehttp/guzzle:~6.0
或者您可以将Guzzle指定为项目现有composer.json中的依赖项
{
"require": {
"guzzlehttp/guzzle": "~6.0"
}
}
使用Guzzle的laravel 5中的示例代码如下所示,
use GuzzleHttp\Client;
class yourController extends Controller {
public function saveApiData()
{
$client = new Client();
$res = $client->request('POST', 'https://url_to_the_api', [
'form_params' => [
'client_id' => 'test_id',
'secret' => 'test_secret',
]
]);
$result= $res->getBody();
dd($result);
}
首先,你必须在你的路线 app/routes.php
/*
API Routes
*/
Route::group(array('prefix' => 'api/v1', 'before' => 'auth.basic'), function()
{
Route::resource('pages', 'PagesController', array('only' => array('index', 'store', 'show', 'update', 'destroy')));
Route::resource('users', 'UsersController');
});
注意:如果您不需要API调用的身份验证,则可以删除'before' => 'auth.basic'
在这里,您可以访问index, store, show, update and destroy您的方法PagesController.
请求网址将是,
GET http://localhost/project/api/v1/pages // this will call index function
POST http://localhost/project/api/v1/pages // this will call store function
GET http://localhost/project/api/v1/pages/1 // this will call show method with 1 as arg
PUT http://localhost/project/api/v1/pages/1 // this will call update with 1 as arg
DELETE http://localhost/project/api/v1/pages/1 // this will call destroy with 1 as arg
命令行CURL请求将是这样的(这里是用户名和密码admin)并假设您有要从url中.htaccess删除的文件index.php,
curl --user admin:admin localhost/project/api/v1/pages
curl --user admin:admin -d 'title=sample&slug=abc' localhost/project/api/v1/pages
curl --user admin:admin localhost/project/api/v1/pages/2
curl -i -X PUT --user admin:admin -d 'title=Updated Title' localhost/project/api/v1/pages/2
curl -i -X DELETE --user admin:admin localhost/project/api/v1/pages/1
接下来,您有一个名为两个控制器PagesController.php和UsersController.php您的app/controllers文件夹中.
PagesController.php,
<?php
class PagesController extends BaseController {
/**
* Display a listing of the resource.
*
* @return Response
* curl --user admin:admin localhost/project/api/v1/pages
*/
public function index() {
$pages = Page::all();;
return Response::json(array(
'status' => 'success',
'pages' => $pages->toArray()),
200
);
}
/**
* Store a newly created resource in storage.
*
* @return Response
* curl --user admin:admin -d 'title=sample&slug=abc' localhost/project/api/v1/pages
*/
public function store() {
// add some validation also
$input = Input::all();
$page = new Page;
if ( $input['title'] ) {
$page->title =$input['title'];
}
if ( $input['slug'] ) {
$page->slug =$input['slug'];
}
$page->save();
return Response::json(array(
'error' => false,
'pages' => $page->toArray()),
200
);
}
/**
* Display the specified resource.
*
* @param int $id
* @return Response
* curl --user admin:admin localhost/project/api/v1/pages/2
*/
public function show($id) {
$page = Page::where('id', $id)
->take(1)
->get();
return Response::json(array(
'status' => 'success',
'pages' => $page->toArray()),
200
);
}
/**
* Update the specified resource in storage.
*
* @param int $id
* @return Response
* curl -i -X PUT --user admin:admin -d 'title=Updated Title' localhost/project/api/v1/pages/2
*/
public function update($id) {
$input = Input::all();
$page = Page::find($id);
if ( $input['title'] ) {
$page->title =$input['title'];
}
if ( $input['slug'] ) {
$page->slug =$input['slug'];
}
$page->save();
return Response::json(array(
'error' => false,
'message' => 'Page Updated'),
200
);
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return Response
* curl -i -X DELETE --user admin:admin localhost/project/api/v1/pages/1
*/
public function destroy($id) {
$page = Page::find($id);
$page->delete();
return Response::json(array(
'error' => false,
'message' => 'Page Deleted'),
200
);
}
}
然后你有一个名为的模型Page将使用名为table的表pages.
<?php
class Page extends Eloquent {
}
您可以使用Laravel4 Generators使用php artisan generator命令创建这些资源.阅读这里.
因此,使用此路由分组,您可以使用相同的应用程序来发出API请求并作为前端.
您可以选择使用的内容:
file_get_contents:
$json = json_decode(file_get_contents('http://host.com/api/v1/users/1'), true);
