php 用guzzule 6 发送HTTP请求

guzzle不知不觉升级到六，升级以后和原来3.*的时候用法不一样了，看文档也迷糊，找了半天才从文档找到用法：
POST

$response = $client->request('POST', 'http://httpbin.org/post', [    'form_params' => [        'field_name' => 'abc',        'other_field' => '123',        'nested_field' => [            'nested' => 'hello'        ]    ]]);$result = $response->getBody();

GET

$client = new Client();$res = $client->request('GET', $url . "?param1=1&param2=9");$result = $res->getBody();

讲道理，还是挺方便的。
