Recently, PHP developers have welcomed a new partner-Guzzle 7.0. As an HTTP client library, Guzzle is welcomed and used by many PHP programmers. Now, with the release of PHP8.0, the Guzzle library has also appeared in our field of vision with a new attitude.
This article will mainly introduce how to use the Guzzle library in PHP8.0 and some tips.
1. Introduction to Guzzle library
Guzzle is an HTTP client library that uses the HTTP protocol and PHP streaming tools to implement fast, scalable, flexible and transparent HTTP requests. It supports synchronous, asynchronous requests and message requests, automatic retry of failed requests, and the ability to customize middleware.
The Guzzle library is very popular in the PHP field and is widely used in RESTful API calls, crawler development, HTTP proxy, etc.
2. New features of Guzzle 7.0
Guzzle 7.0 is the latest version of Guzzle, which introduces some new features in PHP8.0:
->setQuery()
method. 'body' => fopen('/path/to/file', 'r')
and'body' => 'example of string'
way to send the request. 3. Guzzle client example
Next, we will use examples to demonstrate the use of the Guzzle library.
$client = new GuzzleHttpClient(); $response = $client->request('GET', 'https://jsonplaceholder.typicode.com/posts'); echo $response->getBody();
Code analysis: The above code creates a Guzzle client instance, initiates a GET request to the specified URL, and obtains the response result.
$client = new GuzzleHttpClient(); $response = $client->request('POST', 'https://jsonplaceholder.typicode.com/posts', [ 'form_params' => [ 'title' => 'foo', 'body' => 'bar', 'userId' => 1 ] ]); echo $response->getStatusCode(); //200 echo $response->getBody();
Code analysis: The above code creates a Guzzle client instance, initiates a POST request to the specified URL, and passes ## The #form_params option sets the request body content. Finally, this example outputs the HTTP status code and response result.
$client = new GuzzleHttpClient(); $request = new GuzzleHttpPsr7Request('GET', 'https://jsonplaceholder.typicode.com/posts'); $promise = $client->sendAsync($request)->then(function ($response) { echo 'I completed! ' . $response->getStatusCode(); }); $promise->wait();
->wait() method, wait for the asynchronous request to complete and trigger the callback function.
