Web Services 未设置PHP cURL内容类型

我想连接一个简单的Web服务。为了发布一些XML,它将在Web服务端正确地进行,我需要准备一个正确的请求。我使用cURL来完成此任务,如下所示:

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);
}

首先我显示来自curl_getinfo($ch);的请求主体,然后我显示来自$content变量的响应。
发送到服务器的请求的唯一限制是Content-Type头-它必须是application/xml,否则服务器将以错误响应(这不是我的主意,我对此无能为力)
输出请求如下:
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) { } }
响应为HTTP 400 Bad Request
我可以看到的是["content_type"]=> NULL,但我在PHP代码中设置了这个变量...
谁能告诉我我错过了什么?

您设置了两次HTTP_HEADER:

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

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

我想这就是问题所在。第二次设置时,你删除了第一次的设置。
