PHP SoapClient()：发送“User-Agent”和“Accept”HTTP Header

Question

由于防火墙审核，请求必须始终具有“UserAgent”和“Accept”标头。

我试过了：

$soapclient = new soapclient('http://www.soap.com/soap.php?wsdl',
    array('stream_context' => stream_context_create(
        array(
            'http'=> array(
                'user_agent' => 'PHP/SOAP',
                'accept' => 'application/xml')
            )
        )
    )
);

服务器soap收到的请求

GET /soap.php?wsdl HTTP/1.1
Host: www.soap.com
User-Agent: PHP/SOAP
Connection: close

预期结果

GET /soap.php?wsdl HTTP/1.1
Host: www.soap.com
Accept application/xml
User-Agent: PHP/SOAP
Connection: close

为什么没有发送“接受”？ “用户代理”有效！

Answer 1

SoapClient 构造函数在生成请求标头时不会读取所有 stream_context 选项。但是，您可以在 header 选项内的 http 内的单个字符串中放置任意标题：

$soapclient = new SoapClient($wsdl, [
    'stream_context' => stream_context_create([
        'user_agent' => 'PHP/SOAP',
        'http'=> [
            'header' => "Accept: application/xml\r\n
                         X-WHATEVER: something"               
        ]
    ])
]);

如果设置多个，用\r\n分隔。

（正如Ian Phillips 提到的，“user_agent”可以放在 stream_context 的根目录下，也可以放在“http”部分内。）

根据the PHP SoapClient manual page，user_agent 是一个顶级选项。所以你应该像这样修改你的例子：

$soapclient = new SoapClient('http://www.soap.com/soap.php?wsdl', [
    'stream_context' => stream_context_create([
        'http' => ['accept' => 'application/xml'],
    ]),
    'user_agent' => 'My custom user agent',
]);

如果你想让你的代码更灵活，就用这个吧。

$client = new SoapClient(
            dirname(__FILE__) . "/wsdl/" . $env . "/ServiceAvailabilityService.wsdl",
            array(
                'login' => $login,
                'password' => $password
            )
        );
        //Define the SOAP Envelope Headers
        $headers = array();
        $headers[] = new SoapHeader(
            'http://api.com/pws/datatypes/v1',
            'RequestContext',
            array(
                'GroupID' => 'xxx',
                'RequestReference' => 'Rating Example',
                'UserToken' => $token
            )
        );

//Apply the SOAP Header to your client
$client->__setSoapHeaders($headers);

也许你可以使用fsockopen() 方法来做到这一点 像这样

<?php
$sock = fsockopen('127.0.0.1' /* server */, 80 /* port */, $errno, $errstr, 1);

$request = "<Hello><Get>1</Get></Hello>";
fputs($sock, "POST /iWsService HTTP/1.0\r\n");
fputs($sock, "Content-Type: text/xml\r\n");
fputs($sock, "Content-Length: ".strlen($request)."\r\n\r\n");
fputs($sock, "$request\r\n");
$buffer = '';
while($response = fgets($request, 1024)){
    $buffer .= $response;
}
// Then you can parse that result as you want
?>

我现在手动使用该方法从我的指纹机中获取 SOAP 数据。
