未设置PHP cURL Content-Type

我有一个简单的网络服务,我想与之联系。为了发布一些XML,这将在Web服务端正确进行,我需要准备一个正确的请求。我这样使用cURL

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curl_getinfo($ch);的请求正文,然后显示$content变量的响应。

只有发送到服务器的请求的限制是Content-Type标题 - 它必须是application/xml否则服务器将响应错误(这不是我的想法,我不能做任何事情它)

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) { } }

,回复为HTTP 400 Bad Request

我从中可以看到["content_type"]=> NULL,但我在我的PHP代码中设置了这个变量......

有谁能告诉我我错过了什么?

您正在设置两次HTTP_HEADER:

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                                            'Content-Type: application/xml',
                                            'Connection: Keep-Alive'
                                            ));

curl_setopt($ch, CURLOPT_HTTPHEADER,array("Expect:  "));

我猜这就是问题所在。第二次设置时,删除第一个设置。
