所以我刚刚开始尝试理解Guzzle，但我的一个请求一直返回一个错误，即使使用CURL完成完全相同的请求时工作得很好。对我来说，它们看起来一模一样，但也许我忽略了一些关于Guzzle的工作原理。出于安全原因，我已经删除了我的访问令牌和事务id，显然，我使用的真正的令牌具有正确的实际字符串。我正在使用Freeagent API，尽管我不认为我正在谈论的API与它有任何关系。
我确信这是一个简单的错误，源于我不理解Guzzle是如何工作的，但对我来说，这个Guzzle请求和Curl请求看起来是一样的，所以我不明白为什么我得到一个错误和一个成功的请求。
导致错误的Guzzle请求:
$access_token = '{my_access_token_removed}';
$url = 'https://api.freeagent.com/v2/bank_transactions/{myid}';
$guzzleClient = new Client([
'verify' => false
]);
$request = $guzzleClient->get($url, array(
'debug' => true,
'headers' => array(
'User-Agent' => 'sortitoutsi',
'Accept' => 'application/json',
'Content-Type' => 'application/json',
'Authorization' => $access_token
)
));
这个CURL请求工作得很好:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Authorization: Bearer '.$access_token,
'Accept: application/json',
'Content-Type: application/json',
));
curl_setopt($ch, CURLOPT_USERAGENT, 'sortitoutsi');
curl_setopt($ch, CURLOPT_TIMEOUT, 3);
$json_response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
任何想法?我复制并粘贴了下面的整个调试信息和堆栈跟踪。我也在使用Laravel，虽然我也看不出这是一个问题。

我自己想出来的。这只是一个人为的打字错误，它应该是:
'Authorization: Bearer '.$access_token
代替
"授权:"access_token美元。
freeagent api实际上在响应中告诉了我这个，但是guzzle并没有给我错误的信息。
要得到响应，我只需执行以下命令:
try {
$request = $this->guzzle->request('get', $url, array(
'debug' => true,
'headers' => array(
'User-Agent' => 'sortitoutsi',
'Accept' => 'application/json',
'Content-Type' => 'application/json',
'Authorization' => 'Bearer '.$access_token
)
));
} catch (ClientException $e) {
die((string)$e->getResponse()->getBody());
}
