c# - cURL 到 C# webrequest

Question

我正在尝试将 cURL 脚本转换为 C# 脚本。 如果我想发布图片，是否必须将其转换为字符串？

当我尝试运行我的脚本时，我收到来自目标机器的异常。不幸的是，我无权查看目标机器上的代码。

$ch = curl_init();
curl_setopt($ch,CURLOPT_HTTPHEADER,array("Expect:"));
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC ) ;
curl_setopt($ch, CURLOPT_USERPWD, "user:pwd");
curl_setopt($ch, CURLOPT_URL, 'http://192.168.1.105/upload.php');
$data = array('type' => 'upload', 'student' => 'Peter', 'class' => '101', 'fotograf'          => 'Jane', 'file' => '@/pictures/image1.jpg');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);

这是我想出的:

WebRequest request = WebRequest.Create("http://192.168.1.105/upload.php");

request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
string authInfo = "usr:pwd";
request.Headers["Authorization"] = "Basic " + authInfo;
byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes("type=upload&student=Peter&calss=101&fotograf=Jane&file=/pictures/image1.jpg");
Stream reqstr = request.GetRequestStream();
reqstr.Write(buffer, 0, buffer.Length);
reqstr.Close();

WebResponse response = request.GetResponse();

有什么想法吗？

Answer 1

授权 header 和替换可能存在问题:

string authInfo = "usr:pwd";
request.Headers["Authorization"] = "Basic " + authInfo;

与:

request.UseDefaultCredentials = false;
request.Credentials = new NetworkCredential(user, pwd);

可能会解决问题。
