Question

我必须使用curl从Centos主机连接到IIS。

将 curl 与 - ntlm 选项一起使用在命令行上运行正常，但在PHP中运行不正常。服务器是Microsoft IIS，第一次使用401 Unauthorized，第二次通过，200 OK。

经过几个小时的调查后，我找不到合适的解决方案..

当我在命令行（centos 6.4）上使用curl来检索服务的内容时：

curl -v http://example.com/do.asmx --ntlm -u DOMAIN\\username:password

服务器使用以下代码成功回答：

* About to connect() to example.com port 80 (#0)
*   Trying nn.nn.nn.nn... connected
* Connected to example.com (nn.nn.nn.nn) port 80 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
* Server auth using NTLM with user 'DOMAIN\username'

好的，到目前为止，这很好用。现在我试图在php中做同样的事情：

$ch = curl_init();

curl_setopt( $ch, CURLOPT_URL, 'http://example.com/do.asmx' );
curl_setopt( $ch, CURLOPT_HEADER, true );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM );
curl_setopt( $ch, CURLOPT_USERPWD, "DOMAIN\\username:password" );
curl_setopt( $ch, CURLOPT_TIMEOUT, 10 );
curl_setopt( $ch, CURLOPT_VERBOSE, true );


$output = curl_exec($ch);

print_r(curl_getinfo($ch));
echo curl_error($ch);
curl_close($ch);
var_dump($output);

但没有任何反应。结果是

print_r（curl_getinfo（$ ch））：

Array
(
    [url] => http://example.com/do.asmx
    [content_type] => 
    [http_code] => 0
    [header_size] => 0
    [request_size] => 0
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 0
    [namelookup_time] => 0.021611
    [connect_time] => 0
    [pretransfer_time] => 0
    [size_upload] => 0
    [size_download] => 0
    [speed_download] => 0
    [speed_upload] => 0
    [download_content_length] => -1
    [upload_content_length] => -1
    [starttransfer_time] => 0
    [redirect_time] => 0
    [certinfo] => Array
        (
        )

)

echo curl_error（$ ch）：

connect() timed out!

var_dump（$ output）：

bool(false)

怎样才能解决这个问题？这超出了我的知识..

Answer 1

我建议您从http标头Authorization: NTLM TL...中删除base64字符串，因为它可以对其进行解码并读取您的域名和凭据，从而使您面临巨大的安全风险。

除非它们只是内部的，否则也要删除这些IP地址（即使如此，仍然可以删除它们。）

Answer 2

首先，我建议您检查一下安全策略。您的防火墙可以阻止某些软件包。

使用ntlm身份验证的curl在命令行中运行，但不在php内部
