我有一个想要连接的简单网络服务。为了发布一些XML将在 Web 服务端正确进行的 ,我需要准备一个适当的请求。我正在使用cURL这样的:
try {
    $ch = curl_init();
    if (FALSE === $ch)
        throw new Exception('failed to initialize');
    curl_setopt($ch, CURLOPT_URL,"192.168.1.37");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                                            'Content-Type: application/xml',
                                            'Connection: Keep-Alive'
                                            ));
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
    curl_setopt($ch, CURLOPT_PROXY, '');
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE);
    curl_setopt($ch, CURLOPT_HTTPHEADER,array("Expect:  "));
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$xml);
    $request=  curl_getinfo($ch);
    var_dump($request);
    $content = curl_exec($ch);
    if (FALSE === $content)
        throw new Exception(curl_error($ch), curl_errno($ch));
} catch(Exception $e) {
    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),E_USER_ERROR);
}
一切都应该没问题。首先,我显示来自的请求正文curl_getinfo($ch);,然后显示来自$content变量的响应。
将请求发送到服务器的唯一限制是Content-Type标头 - 必须是,application/xml否则服务器将响应错误(这不是我的想法,我对此无能为力)
这是输出请求:
array(21) { ["url"]=> string(68) "192.168.1.37" ["content_type"]=> NULL ["http_code"]=> int(0) ["header_size"]=> int(0) ["request_size"]=> int(0) ["filetime"]=> int(0) ["ssl_verify_result"]=> int(0) ["redirect_count"]=> int(0) ["total_time"]=> float(0) ["namelookup_time"]=> float(0) ["connect_time"]=> float(0) ["pretransfer_time"]=> float(0) ["size_upload"]=> float(0) ["size_download"]=> float(0) ["speed_download"]=> float(0) ["speed_upload"]=> float(0) ["download_content_length"]=> float(-1) ["upload_content_length"]=> float(-1) ["starttransfer_time"]=> float(0) ["redirect_time"]=> float(0) ["certinfo"]=> array(0) { } }
响应是HTTP 400 Bad Request
我可以从中看到的是,["content_type"]=> NULL但我在我的 PHP 代码中设置了这个变量......
谁能告诉我我错过了什么?
