我在PHP中使用Guzzle（v6.1.1）向服务器发出POST请求。它工作正常。我正在添加一些日志记录功能来记录发送和接收的内容，我无法弄清楚如何获取Guzzle发送到服务器的数据。我可以很好地获得响应，但如何获取已发送数据？ （这将是JSON字符串。）
以下是我的代码的相关部分：
$client = new GuzzleHttp\Client(['base_uri' => $serviceUrlPayments ]);
try {
$response = $client->request('POST', 'Charge', [
'auth' => [$securenetId, $secureKey],
'json' => [ "amount" => $amount,
"paymentVaultToken" => array(
"customerId" => $customerId,
"paymentMethodId" => $token,
"publicKey" => $publicKey
),
"extendedInformation" => array(
"typeOfGoods" => $typeOfGoods,
"userDefinedFields" => $udfs,
"notes" => $Notes
),
'developerApplication'=> $developerApplication
]
]);
} catch (ServerErrorResponseException $e) {
echo (string) $e->getResponse()->getBody();
}
echo $response->getBody(); // THIS CORRECTLY SHOWS THE SERVER RESPONSE
echo $client->getBody(); // This doesn't work
echo $client->request->getBody(); // nor does this
任何帮助将不胜感激。我确实试图在Guzzle源代码中查找类似于getBody（）的函数，该函数可以处理请求，但我不是PHP专家，所以我没有提出任何有用的信息。我也经常搜索Google，但发现只有人在讨论从服务器上获取响应，我没有遇到任何问题。

您可以通过创建Middleware来完成这项工作。
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Middleware;
use Psr\Http\Message\RequestInterface;
$stack = HandlerStack::create();
// my middleware
$stack->push(Middleware::mapRequest(function (RequestInterface $request) {
$contentsRequest = (string) $request->getBody();
//var_dump($contentsRequest);
return $request;
}));
$client = new Client([
'base_uri' => 'http://www.example.com/api/',
'handler' => $stack
]);
$response = $client->request('POST', 'itemupdate', [
'auth' => [$username, $password],
'json' => [
"key" => "value",
"key2" => "value",
]
]);
然而，这是在收到回复之前触发的。你可能想做这样的事情：
$stack->push(function (callable $handler) {
return function (RequestInterface $request, array $options) use ($handler) {
return $handler($request, $options)->then(
function ($response) use ($request) {
// work here
$contentsRequest = (string) $request->getBody();
//var_dump($contentsRequest);
return $response;
}
);
};
});

使用Guzzle 6.2。
在过去的几天里，我一直在努力解决这一问题，同时尝试构建一种方法来审核与不同API的HTTP交互。在我的情况下，解决方案是简单地倒退请求正文。
请求的正文实际上是作为stream实现的。因此，发送请求时，Guzzle从流中读取。读取完整的流会将流的内部指针移到末尾。因此，在发出请求后调用getContents()时，内部指针已经位于流的末尾，并且不返回任何内容。
解决方案？将指针倒退到开头，然后再次读取流。
<?php
// ...
$body = $request->getBody();
echo $body->getContents(); // -->nothing
// Rewind the stream
$body->rewind();
echo $body->getContents(); // -->The request body :)

这会将您的数据输出为JSON字符串。
http://php.net/manual/fr/function.json-encode.php
上的文档修改
Guzzle有一个$data = array(
"key" => "value",
"key2" => "value",
);
$response = $client->request('POST', 'itemupdate', [
'auth' => [$username, $password],
'json' => $data,
]);
// ...
echo json_encode($data);
和一个Request类（以及许多其他类）
Response实际上有一个Request方法，该方法将包含您getQuery()的对象作为私有对象返回，与所有其他成员相同。
你也无法访问它。
这就是为什么我认为手动编码它是更容易的解决方案。
如果你想知道Guzzle做了什么，它还有一个data类来转换数据并在请求中发送它。

我的 Laravel 5.7版本的解决方案：
MessageFormatter可用于变量替换，请参见：https://github.com/guzzle/guzzle/blob/master/src/MessageFormatter.php
$stack = HandlerStack::create();
$stack->push(
Middleware::log(
Log::channel('single'),
new MessageFormatter('Req Body: {request}')
)
);
$client = new Client();
$response = $client->request(
'POST',
'https://url.com/go',
[
'headers' => [
"Content-Type" => "application/json",
'Authorization' => 'Bearer 123'
],
'json' => $menu,
'handler' => $stack
]
);
