Class 放大器未找到

Question

I'm new on amphp and i'd like to try this very simple code first. I downloaded amphp with composer for windows and save all folder created inside my project folder.

composer require amphp/http-client

Then my code is:

<?php

require __DIR__ . './autoload.php';

use Amp\Http\Client\HttpClientBuilder;
use Amp\Http\Client\HttpException;
use Amp\Http\Client\Request;
use Amp\Http\Client\Response;
use Amp\Loop;

$stringa = 'http://www.google.it/';

$request = new Request($stringa, "GET");
$location = $request->getHeader("Location");

var_dump($location);

But I get always 'Fatal error: Uncaught Error: Class 'Amp\Http\Client\Request' not found'

Any suggest?

I use wamp local server with php 7.0

Also,after, I need to yield all the code...

Here are a few things that look for:

• Did the autoload.php get included correctly?
  • I see there is an unnecessary . before /autoload.php .
• Did you use the correct class name with the correct namespace?
• Did you run composer require amphp/http-client so that the libraries will be installed?
• Do the library's files exist inside the vendor/amphp/http-client directory?
• If you're on Windows, use \ in the require statement.

Apart from these, I can't think of why the library won't load. I hope this helps.
