Laravel's HTTP client is easy to use, especially since Laravel 7 built-in Guzzle-based encapsulation. 1. To initiate a GET request, you can use the Http::get() method, such as $response = Http::get('https://api.example.com/data'); 2. To obtain JSON data, you can use $data = $response->json() to determine success using successful() or ok(); 3. To interrupt the program when failing, you can add throw(); 4. To use withHeaders() to request with headers, such as setting User-Agent and Accept; 5. To pass the GET query parameters directly into the array as the second parameter; 6. To use the post() method for POST request and pass the data array; 7. To control timeout, use timeout() to specify the number of seconds; 8. To use pool() for concurrent requests Improve efficiency.

Laravel's HTTP client is actually quite convenient to use, especially since Laravel 7 has built-in Guzzle-based encapsulation, which saves the hassle of manually configuring and introducing third-party libraries. Using it to send external requests is not only concise, but also very intuitive.

How to initiate a basic GET request

In Laravel, using Http::get() is the most common way. For example, if you want to call an API to get data:

 use Illuminate\Support\Facades\Http;

$response = Http::get('https://api.example.com/data');

The result returned is a response object, you can get JSON data through json() method:

 $data = $response->json();

If you just need to determine whether it is successful, you can use successful() or ok() :

 if ($response->successful()) {
    // Process data}

It should be noted that by default Laravel does not throw exceptions. If you want to interrupt the program when it fails, you can add throw() :

 $response = Http::get('https://api.example.com/data')->throw();

How to send requests with parameters and headers

Many times you need to pass parameters or set request headers. At this time, you can use methods such as withHeaders() and withOptions() .

For example, bring custom User-Agent and Accept:

 $response = Http::withHeaders([
    'User-Agent' => 'MyApp/1.0',
    'Accept' => 'application/json'
])->get('https://api.example.com/data');

It is also very simple to request the transmission of query parameters by GET. You can directly pass the parameters as the second parameter:

 $response = Http::get('https://api.example.com/search', [
    'query' => 'laravel',
    'page' => 2
]);

The POST request is replaced by post() method and passes the data:

 $response = Http::post('https://api.example.com/submit', [
    'name' => 'John',
    'email' => 'john@example.com'
]);

How to handle timeouts, retry and errors

By default, Laravel's HTTP client does not set a timeout, which may be less secure in production environments. It is recommended to add timeout() to control the maximum waiting time (unit is seconds):

 $response = Http::timeout(5)->get('https://api.example.com/data');

If you want to automatically retry several times in the event of a network problem, you can combine PHP loops or use a package like retry() , but Laravel natively does not support automatic retry.

In addition, sometimes you may need to access the original Guzzle client to do some advanced operations, you can implement concurrent requests through HttpClient::pool() , or use Http::fake() to simulate responses in tests.

A few easy to ignore but practical tips

• Logging : During the debugging stage, request information can be recorded, such as URL, response status code, etc.

• Environment distinction : Configure different API addresses in .env files to avoid hard coding.

• Connection pool optimization performance : If you want to send multiple requests at the same time, using pool() can improve efficiency:

   $responses = Http::pool(fn ($pool) => [
      $pool->get('https://api.example.com/endpoint1'),
      $pool->get('https://api.example.com/endpoint2'),
  ]);

  Basically that's it. Laravel's HTTP Client is not complicated to use, but some details such as the order of headers and exception handling methods should be paid more attention to.
