Python：计算单词的长度[重复](Python: count length of word [duplicate])

 看看$ this - > _ apiContext包含什么。 有一种模式需要设置为live才能使其正常工作。 
 
 如果未找到，您可以创建apiContext对象，如下所示： 
 
$apiContext = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
        'Live ClientId',     // ClientID
        'Live Client Secret'      // ClientSecret
    )
);

$apiContext->setConfig(
  array(
    'mode' => 'live',
    'log.LogEnabled' => true,
    'log.FileName' => 'PayPal.log',
    'log.LogLevel' => 'FINE'
  )
);
 
 当你调用$payment->create();时，改用$ apiContext $payment->create(); 

Look what $this->_apiContext contains. There is a mode that needs to be set to live to make it work.
 
If not found, you can create apiContext object as shown here:
 
$apiContext = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
        'Live ClientId',     // ClientID
        'Live Client Secret'      // ClientSecret
    )
);

$apiContext->setConfig(
  array(
    'mode' => 'live',
    'log.LogEnabled' => true,
    'log.FileName' => 'PayPal.log',
    'log.LogLevel' => 'FINE'
  )
);
 
and use $apiContext instead when you call $payment->create();
