我在使用WebClient使用htaccess向apache服务器发送POST请求时遇到了问题（我曾尝试使用HttpRequest和WebRequest，但结果相同）。我从PHP上的供应商那里得到了以下例子：
$soap = curl_init(url);
curl_setopt($soap, CURLOPT_POST, 1);
curl_setopt($soap, CURLOPT_RETURNTRANSFER, 1);
$XML = file_get_contents("test.xml");
$request = <<<XML
$XML
XML;
curl_setopt($soap, CURLOPT_HTTPHEADER, array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen($request)));
curl_setopt($soap, CURLOPT_POSTFIELDS, $request);
$response = curl_exec($soap);
curl_close($soap);
我在C#上的版本是：
public static string Post(string login, string password, string url, string content) {
var result = String.Empty;
var uri = new Uri(url);
using (var client = new WebClient()) {
client.Credentials = new NetworkCredential(login, password);
client.Encoding = Encoding.UTF8;
client.Headers[HttpRequestHeader.ContentType] = "text/xml; charset=UTF-8";
client.Headers[HttpRequestHeader.Accept] = "application/xml";
result = client.UploadString(uri, content);
}
return result;
}
当我运行程序时，我遇到了一个异常，错误为400（错误请求）。我已经使用Fiddler2探查了该请求，并发现以下错误消息："请求标头字段缺少'：'分隔符"有人能帮我找到请求中的错误以及服务器拒绝请求的原因吗
p.S：请求头
POST http://production.is.topdelivery.ru/tests/xmlGate/index.php HTTP/1.1
Content-Type: text/xml; charset=utf-8
Authorization: Basic YmFiYWR1OmJhYmFkdXBhc3M=
Host: production.is.topdelivery.ru
Content-Length: 1617
Expect: 100-continue
在我的情况下，以下代码正常工作
private string post(string content)
{
var result = String.Empty;
var uri = new Uri(_url);
WebRequest req = HttpWebRequest.Create(uri);
req.Method = "POST";
req.ContentType = "text/xml";
String encoded = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes("user:pass"));
req.Headers.Add("Authorization", "Basic " + encoded);
using (var s = req.GetRequestStream())
using (var sw = new StreamWriter(s, Encoding.UTF8))
{
sw.Write(content);
}
using (var s = req.GetResponse().GetResponseStream())
using (var sr = new StreamReader(s, Encoding.UTF8))
{
result = sr.ReadToEnd();
};
return result;
}
这对我很有帮助。我遇到了一个问题，一个新版本的Apache看不到凭据，尽管旧版本没有问题。我更改了
client.Credentials = new NetworkCredential(login, password);
至
String encoded = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes("user:pass"));
req.Headers.Add("Authorization", "Basic " + encoded);
它成功了！
谢谢。
