如何在不使用 curl 和 guzzle 的情况下从控制器 Laravel 调用 API，因为它不起作用

How to call API from controller Laravel without using curl and guzzle as its not working

提问by Mahendra Pratap

How to call an API from a controller using a helper in laravel without using curl and guzzle because both returing nothing. I have tested in postman the api is working fine but not in laravel. I need to call several API's from different controllers so what would be a good way to do this? Should i build a helper?

如何使用 Laravel 中的帮助程序从控制器调用 API，而不使用 curl 和 guzzle，因为两者都没有返回任何内容。我已经在邮递员中测试过，api 工作正常，但在 laravel 中却没有。我需要从不同的控制器调用多个 API，那么这样做的好方法是什么？我应该建立一个助手吗？

I used curl but it is always giving me a false response.

我使用 curl 但它总是给我错误的响应。

EDIT:

编辑：

I am looking for a reliable way to make api calls to various url's without having to rewrite the sending and receiving code for each api I want to use. Preferably a solution that implements "dry" (don't repeat yourself) principles and would serve as a base for any api specific logic, (parsing the response /translating for a model). That stuff would extend this base.

我正在寻找一种可靠的方法来对各种 url 进行 api 调用，而不必为我想要使用的每个 api 重写发送和接收代码。最好是一个实现“干”（不要重复自己）原则的解决方案，并将作为任何 api 特定逻辑的基础，（解析响应/翻译模型）。那东西会扩展这个基础。

you can use Guzzle pacakge docs: https://github.com/guzzle/guzzle

您可以使用 Guzzle pacakge 文档：https: //github.com/guzzle/guzzle

installation

安装

composer require guzzlehttp/guzzle

GET

得到

    $client = new \GuzzleHttp\Client();
    $request = $client->get('example.com');
    $response = $request->getBody();
    return $response;

POST

邮政

    $client = new \GuzzleHttp\Client();
    $body['name'] = "Testing";
    $url = "http://my-domain.com/api/v1/post";
    $response = $client->request("POST", $url, ['form_params'=>$body]);
    $response = $client->send($response);
    return $response;

Some Usefull Methods

一些有用的方法

    $response->getStatusCode(); # 200
    $response->getHeaderLine('content-type'); # 'application/json; charset=utf8'
    $response->getBody(); # '{"id": 1420053, "name": "guzzle", ...}'

• We can also send asynchronous request

• 我们也可以发送异步请求

    $request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
    $promise = $client->sendAsync($request)->then(function ($response) {
        echo 'I completed! ' . $response->getBody();
    });
    $promise->wait();

• we can also add headers

• 我们还可以添加标题

    $header = array('Authorization'=>'token');
    $client = new \GuzzleHttp\Client();
    $request = $client->get('example.com',array('headers' => $header));
    $response = $request->getBody();

Helper For this Method

此方法的助手

we can create a common helper for these methods.

我们可以为这些方法创建一个通用的助手。

• firstly create folder in app folder

• 首先在app文件夹中创建文件夹

    app\Helper

• then create a file inside Helper folder

• 然后在 Helper 文件夹中创建一个文件

    app\Helper\Helper.php

• add this code in Helper.php

• 在 Helper.php 中添加此代码

<?php 

namespace App\Helper;
class Helper
{

    public static function GetApi($url)
    {
        $client = new \GuzzleHttp\Client();
        $request = $client->get($url);
        $response = $request->getBody();
        return $response;
    }


    public static function PostApi($url,$body) {
        $client = new \GuzzleHttp\Client();
        $response = $client->request("POST", $url, ['form_params'=>$body]);
        $response = $client->send($response);
        return $response;
    }
}

• Now in controller use

• 现在在控制器使用

    use App\Helper\Helper;
    Helper::GetApi('ultimateakash.com');

We can also do this without helper

我们也可以在没有帮手的情况下做到这一点

• In Main controller we can create these functions

• 在主控制器中，我们可以创建这些功能

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function GetApi($url)
    {
        $client = new \GuzzleHttp\Client();
        $request = $client->get($url);
        $response = $request->getBody();
        return $response;
    }


    public function PostApi($url,$body) {
        $client = new \GuzzleHttp\Client();
        $response = $client->request("POST", $url, ['form_params'=>$body]);
        $response = $client->send($response);
        return $response;
    }
}

• Now in controllers we can call

• 现在在控制器中我们可以调用

    $this->GetApi('ultimateakash.com');
