如何在 php 的 SoapClient 中设置和禁用 headers？

Question

SoapClient 发送 HTTP header:

POST / HTTP/1.1
Accept: */*
Accept-Encoding: deflate, gzip
SOAPAction: ""
Content-Type: text/xml; charset=utf-8
Content-Length: 2085
Expect: 100-continue

HTTP/1.1 100 Continue

我想禁用 Expect: 100-continue。我该怎么做？

我发现我应该可以通过以下方式设置自定义 header：

class SoapClient extends \SoapClient implements HttpClientInterface

    public function __construct($pathToWSDL, array $options, LoggerInterface $logger){
        ...
        $headers = [
            'stream_context' => stream_context_create(
                [
                    'http' => [
                        'header' => 'SomeCustomHeader: value',
                    ],
                ]
            ),
        ];
        parent::__construct($pathToWSDL, array_merge($options, $headers));
 }

但这不起作用。

如何设置自定义 header 并禁用某些？

我也没有使用本机 php，而是 HipHop VM 3.12.1（rel）。

Answer 1

HTTP context options indicate that the header option can be a string or an array of strings, and will override other given options. If you want to use a single string with multiple options, you would separate with a carriage return and newline (\r\n) as illustrated in the first stream_context_create例子，.

所以构造将是：

'stream_context' => stream_context_create(
    [
        'http' => [
            'header' => "SomeCustomHeader: value\r\n".
                        "Expect: \r\n",
        ],
    ]
),

或者：

'stream_context' => stream_context_create(
    [
        'http' => [
            'header' => [
                'SomeCustomHeader: value',
                'Expect: ',
            ],
        ],
    ]
),

但在您的情况下，最有可能的原因是您使用的 HHVM 版本 - 这是 a bug in HHVM which doesn't appears to have been fixed in 3.15.0 因此您可能想尝试升级 HHVM 并重试。

Answer 2

是的，我已经使用 stream_context_create 来设置一些额外的 HTTP header。我不知道删除其中一个，但也许你可以覆盖一个。那么，您是否尝试过设置一个空的 Expect header?

$headers = [
    'stream_context' => stream_context_create(
        [
            'http' => [
                'header' => 'Expect: ',
            ],
        ]
    ),
];

一般来说，这种方法有点矫枉过正，但如果你想解决 stream_context_create 周围的 HHVM 错误，你可以尝试完全覆盖 SoapClient::__doRequest

有点喜欢这个

public function __doRequest($request, $location, $action, $version, $one_way=0)
{
    // @note Omitted Expect: 100-continue
    $headers = [
        'Accept: */*',
        'Accept-Encoding: deflate, gzip',
        'SOAPAction: ""',
        'Content-Type: text/xml; charset=utf-8',
        'Content-Length: ' . strlen($request),
        'HTTP/1.1 100 Continue',
    ];

    $ch = curl_init($location);
    curl_setopt_array(
        $ch, [
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_POST           => true,
            CURLOPT_POSTFIELDS     => $request,
            CURLOPT_HTTPHEADER     => $headers,
        ]);

    $response = curl_exec($ch);

    curl_close($ch);

    return $response;
}

我将这种方法用于 implement SOAP with Attachments，并且效果很好，尽管是在标准 PHP 解释器下。
