axiosvssymfony-http
axios is a popular JavaScript library that allows you to make HTTP requests from a Node.js environment. It is a promise-based library that works in both the browser and Node.js. It is similar to the Fetch API, but with a more powerful feature set and better browser compatibility.
One of the main benefits of using axios is that it automatically transforms the response data into a JSON object, making it easy to work with.
Axios is known for user-friendly API and support for asynchronous async/await syntax making it very accessible in web scraping.
Symfony-http is a PHP library that provides a set of classes for working with HTTP requests and responses. It is part of the Symfony CMS framework, but can also be used independently.
Example Use
// axios can be used with promises:
axios.get('http://httpbin.org/json')
.then(response => {
console.log(response.data);
})
.catch(error => {
console.log(error);
});
// or async await syntax:
var resp = await axios.get('http://httpbin.org/json');
console.log(resp.data);
// to make requests concurrently Promise.all function can be used:
const results = await Promise.all([
axios.get('http://httpbin.org/html'),
axios.get('http://httpbin.org/html'),
axios.get('http://httpbin.org/html'),
])
// axios also supports other type of requests like POST and even automatically serialize them:
await axios.post('http://httpbin.org/post', {'query': 'hello world'});
// or formdata
const data = {name: 'John Doe', email: 'johndoe@example.com'};
await axios.post('https://jsonplaceholder.typicode.com/users',
querystring.stringify(data),
{
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}
);
// default values like headers can be configured globally
axios.defaults.headers.common['User-Agent'] = 'webscraping.fyi';
// or for session instance:
const instance = axios.create({
headers: {"User-Agent": "webscraping.fyi"},
})
<?php
use Symfony\Component\HttpClient\HttpClient;
// create a client object:
$client = HttpClient::create();
// sent GET request
$response = $client->request('GET', 'https://httpbin.org/get');
// or POST request
$response = $client->request('POST', 'https://httpbin.org/post', [
'headers' => [
'Content-Type' => 'application/json',
],
'json' => [
'name' => 'John Doe',
'email' => 'john.doe@example.com',
],
]);
// print response data:
$statusCode = $response->getStatusCode();
$content = $response->getContent();
echo "Status Code: $statusCode\n";
echo "Content: $content\n";
