如何在 Guzzle 中获取响应体

Question

当我使用 Guzzle 发布请求时如何获得响应我使用"guzzle/guzzle": "^3.9", 我发布一些 url 请求并且我需要响应正文，但是使用 Guzzle 我没有发现这是响应，在使用标准 php 函数的地方file_get_contents我有响应正文。Guzzle het反应体如何？

$guzzle = new Client();
$postCell = $guzzle
    ->post($url, [], $addProtectedRangeJson)
    ->addHeader('Authorization', 'Bearer ' . $arrayAccessTokenClient)
    ->addHeader('Content-type', 'application/json')
;

$postCell
    ->send()
    ->getBody(true)
;

$contents = (string) $postCell->getBody(); // get body that I post -> my request, not response
$contents = $postCell->getBody()->getContents(); // not find getContents, ask me did you mean to call getContentMd5 
$answer = json_decode($postCell->getResponse()->getBody(), true);

return $answer;

现在$answer：

result = {Guzzle\Http\EntityBody} [7]
readWriteHash = {array} [2]
contentEncoding = false
rewindFunction = null
stream = {resource} resource id='77' type='stream'
size = null
cache = {array} [9]
 wrapper_type = "PHP"
 stream_type = "TEMP"
 mode = "w+b"
 unread_bytes = 0
 seekable = true
 uri = "php://temp"
 is_local = true
 is_readable = true
 is_writable = true
customData = {array} [1]
 default = true

我尝试$contents = (string) $postCell->getBody();但有我的请求，而不是回应，但我需要回应

        $url = 'some_url';
    $opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'=>"Content-type: application/json\r\n" .
                "Authorization: Bearer $arrayAccessTokenClient\r\n",
            'content' => $addProtectedRangeJson
        )
    );
    // Creating the context for the request
    $context = stream_context_create($opts);
    $response = file_get_contents($url, FALSE, $context);
    $responseData = json_decode($response, TRUE);

如何在 Guzzle 中获得响应体？

我尝试 http 狂饮

$headers = [
        'Authorization' => 'Bearer ' . $arrayAccessTokenClient,
        'Content-type' => 'application/json'
    ];
    $guzzle = new \GuzzleHttp\Client($headers);

    $request = $guzzle
        ->post('https://sheets.googleapis.com/v4/spreadsheets/' . $spreadsheetId . ':batchUpdate',
            $addProtectedRange
        );
    $response = $request->getBody()->getContents();

    return $response;

但是有401吗？热添加标题？

更新

    $headers = [
        'Authorization' => 'Bearer ' . $arrayAccessTokenClient,
        'Content-type' => 'application/json'
    ];
    $guzzle = new \GuzzleHttp\Client();
    $request = new Request('POST', 'https://sheets.googleapis.com/v4/spreadsheets/' . $spreadsheetId . ':batchUpdate', $headers);
    $response = $guzzle
        ->send($request, $addProtectedRange);

    $answer = $response->getBody()->getContents();

    return $answer;

但有

  "Catchable Fatal Error: Argument 1 passed to GuzzleHttp\\Client::send() must be an instance of Psr\\Http\\Message\\RequestInterface, instance of Guzzle\\Http\\Message\\Request given, called in /home/ivan/host/aog-code/src/Artel/SiteBundle/Helper/GoogleSpreadSheetHelper.php on line 144 and defined"

Answer 1

我找到解决方案

$headers = [
    'Authorization' => 'Bearer ' . $arrayAccessTokenClient,
    'Content-type' => 'application/json'
];
$guzzle = new \GuzzleHttp\Client();
$request = new \GuzzleHttp\Psr7\Request('POST', 'https://sheets.googleapis.com/v4/spreadsheets/' . $spreadsheetId . ':batchUpdate', $headers);
$response = $guzzle
    ->send($request, ['body' => $addProtectedRangeJson]);

$answer = $response->getBody()->getContents();

return $answer;
