superagent is an HTTP client library for Node.js that provides a simple, flexible, and powerful API for making HTTP requests.
It supports all major HTTP methods, and has a clean and easy-to-use interface for handling responses and errors.
what differentiates superagent from other http clients is its simple declarative API.
Guzzle is a PHP HTTP client library that makes it easy to send HTTP requests and trivial to integrate with
web services. It allows you to send HTTP/1.1 requests with various methods
like GET, POST, PUT, DELETE, and others.
Guzzle also supports sending both synchronous and asynchronous requests, caching, and even has
built-in support for OAuth 1.0a.
Additionally, it can handle different HTTP errors and handle redirects automatically.
It also has built-in support for serializing and deserializing data using formats like JSON and XML,
as well as sending multipart file uploads.
Overall Guzzle is an easy to use and powerful library for working with HTTP in PHP.
```javascript
const superagent = require('superagent');
// superagent supports both Promises and async/await
superagent.get('https://httpbin.org/get')
.then(res => console.log(res.text))
.catch(err => console.error(err));
const response = superagent.get('https://httpbin.org/get')
// post requests:
superagent.post('https://httpbin.org/post').send({ name: 'John Doe' })
// setting proxy
superagent.get('https://httpbin.org/ip').proxy('http://proxy.example.com:8080')
// settings headers and proxies
superagent.get('https://httpbin.org/headers').set('Cookie', 'myCookie=123').set('X-My-Header', 'myValue')
```
```php
use GuzzleHttp\Client;
// Create a client session:
$client = new Client();
// can also set session details like headers
$client = new Client([
'headers' => [
'User-Agent' => 'webscraping.fyi',
]
]);
// GET request:
$response = $client->get('http://httpbin.org/get');
// print all details
var_dump($response);
// or the important bits
printf("status: %s\n", $response->getStatusCode());
printf("headers: %s\n", json_encode($response->getHeaders(), JSON_PRETTY_PRINT));
printf("body: %s", $response->getBody()->getContents());
// POST request
$response = $client->post(
'https://httpbin.org/post',
// for JSON use json argument:
['json' => ['query' => 'foobar', 'page' => 2]]
// or formdata use form_params:
// ['form_params' => ['query' => 'foobar', 'page' => 2]]
);
// For ASYNC requests getAsync function can be used:
$promise1 = $client->getAsync('https://httpbin.org/get');
$promise2 = $client->getAsync('https://httpbin.org/get?foo=bar');
// await it:
$results = Promise\unwrap([$promise1, $promise2]);
foreach ($results as $result) {
echo $result->getBody();
}
// or add promise callback
Promise\each([$promise1, $promise2], function ($response, $index, $callable) {
echo $response->getBody();
});
```
