guzzle xml 请求仅返回纯文本

Question

我正在尝试使用 guzzle 向 ws 发出 xml 请求，（我尝试使用 curl to）在 php 中，但始终以纯文本形式的响应在 xml 中没有

    $client = new \GuzzleHttp\Client(['verify' => false]);

        $soapRequest  = <<<XML
        <soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/" xmlns:san="mywebsservice">

                </soap:Body>                    
        </soap:Envelope>
XML;
        $request = $client->request('POST','mywebsservice', [
            'headers' => [
                'Content-Type' => 'application/soap+xml'
            ],
            'body' => $soapRequest                         
        ]);
        $response = $request->getBody()->getContents();
    var_dump($response);

您发送的标头是接收服务器用来决定要提供哪些内容的标头。虽然它仍然是文本内容，但只有不同的 Content-Type 标头。

guzzlehttp/guzzle 6.x

在 6.x 中删除了 $response->json() 和 $response->xml() 助手。以下行可用于复制该行为：

// Get an associative array from a JSON response.
$data = json_decode($response->getBody(), true);

见https://www.php.net/manual/en/function.json-decode.php

// Get a `SimpleXMLElement` object from an XML response.
$xml = simplexml_load_string($response->getBody());

见https://www.php.net/manual/en/function.simplexml-load-string.php

guzzlehttp/guzzle 5.x

Guzzle 5.x 有一些快捷键可以帮助您：

$client = new Client(['base_uri' => 'https://example.com']);

$response = $client->get('/');
// $response = Psr\Http\Message\ResponseInterface

$body = (string) $response->getBody();
// $body = raw request contents in string format.
// If you dont cast `(string)`, you'll get a Stream object which is another story.

现在，无论您如何处理 $body，都由您决定。如果是 JSON 响应，你会这样做：

$data = $response->json();

如果是XML，可以调用：

$xml = $response->xml();

我从不使用 XML API，所以我不能再给你提供更多关于如何遍历你将检索到的 XML 的示例。
