C# 和 php 中的 NTLM 请求

Question

我在 C# 中有一个 ntlm 请求可以正常工作，在 php 中有相同的请求可以连接，但是 returns 响应中有一个错误。

这是 C# 代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://example.com/Query/ExecuteReportView");
            httpWebRequest.ContentType = "text/json";
            httpWebRequest.Method = "POST";

            httpWebRequest.UseDefaultCredentials = false;
            httpWebRequest.PreAuthenticate = true;
            var c = new NetworkCredential("username", "password", "domain");

            CredentialCache credentialCache = new CredentialCache();
            credentialCache.Add(new Uri("http://example.com"), "NTLM", c);
            httpWebRequest.Credentials = credentialCache;

            using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                string json = "{\"SysName\":\"Callbacks\"," +
                                "\"SysCategory\":\"Eai.CCM.Model.FolderView\"," +
                                "\"StartIndex\":0," +
                                "\"PageLength\":10}";


                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();
            }

            var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
            {
                var result = streamReader.ReadToEnd();
                Console.Out.WriteLine(result);
            }

            Console.ReadLine();
        }
    }
}

有效，并且 returns 是预期的 json 字符串。

这是我尝试在 php 中做同样的事情：

<?php
$data = array
(
  "SysName" => "Callbacks",
  "SysCategory" => "Eai.CCM.Model.FolderView",
  "StartIndex" => 0,
  "PageLength" => 10
);
$body = json_encode($data);
$headers = array(
    "Transfer-Encoding: chunked",
    "Content-Type: application/json"
);

$ch = curl_init();

curl_setopt($ch, CURLOPT_USERPWD, 'username:password');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, 'example.com/Query/ExecuteReportView');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
curl_setopt($ch, CURLOPT_MAXREDIRS, 100);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, dechex(strlen($body)) . "\r\n" . $body . "\r\n");

curl_exec($ch);

curl_close($ch);
?>

一个显着差异是 php 代码使用分块编码，因为内容长度方法不断给我一个错误，告诉我需要指定内容长度或分块发送数据。

在我的 php 脚本中，是否有任何明显突出的东西被我遗漏了？

php 脚本连接并返回响应，所以我显然没有给它正确的信息（因为我在 c# 版本中）。

这就是 php 版本 returns:

{"$id":"1","Message":"An error has occurred.","ExceptionMessage":"Object reference not set to an instance of an object.","ExceptionType":"System.Exception","StackTrace":null}

我正在使用 php 5.6.6.

编辑：

我的 php 脚本在 php 5.2.17 中使用内容长度而不是分块编码数据

在 php 5.5.21

中有同样的问题

phpinfo 为 5.2.17 提供以下信息：

Answer 1

终于得到答案：

似乎 IIS 正在为我做一些事情。似乎发送 header "Transfer-Encoding: chunked" 告诉 IIS 为我做分块。所以我不需要自己分块数据。

<?php
$data = array
(
  "SysName" => "Callbacks",
  "SysCategory" => "Eai.CCM.Model.FolderView",
  "StartIndex" => 0,
  "PageLength" => 10
);
$body = json_encode($data);
$headers = array(
    "Transfer-Encoding: chunked",
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, 'username:password');
curl_setopt($ch, CURLOPT_URL, 'example.com/Query/ExecuteReportView');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
curl_exec($ch);
curl_close($ch);
?>
