无法从Patreon JSON API读取数据

Question

使用Packagist (https://packagist.org/packages/patreon/patreon?q=&p=6)提供的代码，我无法获得预期的结果。我的代码现在让用户登录，并返回他们的数据(我可以通过var_dump查看)，但我在实际读取时遇到了问题。

根据Patreon API文档，除非另行指定，否则从API接收的数据将自动设置为数组。我正在运行他们网站上的代码，但他们的API返回了一个对象，我不确定如何读取用户的数据并从中获得承诺信息。我尝试过将返回数据设置为数组或json，但没有成功。当我将API响应转换为数组时，我就会得到这种混乱的结果。

require_once __DIR__.'/vendor/autoload.php';

use Patreon\API;
use Patreon\OAuth;

$client_id = 'removed';
$client_secret = 'removed';

$redirect_uri = "https://s.com/redirect";

$href = 'https://www.patreon.com/oauth2/authorize?response_type=code&client_id=' . $client_id . '&redirect_uri=' . urlencode($redirect_uri);

$state = array();

$state['final_page'] = 'http://s.com/thanks.php?item=gold';

$state_parameters = '&state=' . urlencode( base64_encode( json_encode( $state ) ) );

$href .= $state_parameters;

$scope_parameters = '&scope=identity%20identity'.urlencode('[email]');

$href .= $scope_parameters;

echo '<a href="'.$href.'">Click here to login via Patreon</a>';

if (isset($_GET['code']))
{
    $oauth_client = new OAuth($client_id, $client_secret);  
    $tokens = $oauth_client->get_tokens($_GET['code'], $redirect_uri);

    $access_token = $tokens['access_token'];
    $refresh_token = $tokens['refresh_token'];

    $api_client = new API($access_token);
    $campaign_response = $api_client->fetch_campaign();

    $patron = $api_client->fetch_user();
    $patron = (array)$patron;
    die(var_dump($patron));
}

我希望能够查看用户的数据和承诺信息。我尝试过$patron->data->first_name，$patron'data‘等，它们都抛出了有关未找到数组索引的错误。

你可能已经弄明白了一些事情，但我也遇到了同样的事情，我想我应该在这里分享一个解决方案。

patreon库返回的JSONAPIResource对象有几个特定的方法，可以以可读的格式返回各个数据段。

import patreon
from pprint import pprint

access_token = <YOUR TOKEN HERE>   # Replace with your creator access token

api_client = patreon.API(access_token)
campaign_response = api_client.fetch_campaign()

campaign = campaign_response.data()[0]
pprint(campaign.id()) # The campaign ID (or whatever object you are retrieving)
pprint(campaign.type()) # Campaign, in this case
pprint(campaign.attributes()) # This is most of the data you want
pprint(campaign.attribute('patron_count')) # get a specific attribute
pprint(campaign.relationships()) # related entities like 'creator' 'goals' and 'rewards'
pprint(campaign.relationship('goals'))
pprint(campaign.relationship_info()) 
# This last one one ends up returning another JSONAPIResource object with it's own method: .resource() that returns a list of more objects 
# for example, to print the campaign's first goal you could use:
pprint( campaign.relationship_info('goals').resource()[0].attributes() )

希望这对某些人有帮助！
