HttpURLConnection类没有找到在Android上的NTLM挑战 [英] HttpUrlConnection doesn't find the NTLM challenge on Android

问题描述

我想我的Andr​​oid应用程序连接到使用的HttpURLConnection类IIS服务器。

I'm trying to connect my Android app to an IIS server using the HttpUrlConnection class.

我的服务器需要用户为进行验证，所以它发送下面挑战给客户端：

My server needs the user to be authenticate, so it is sending the following challenge to the client :

WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM

我的问题是HttpURLConnection的似乎并不解析它。所以的getPasswordAut​​hentication（）永远不会调用，并返回一个IOException异常无身份验证的挑战找到了。

My problem is that HttpUrlConnection doesn't seems to parse it. So getPasswordAuthentication() is never call, and it return an IOException "no authentication challenges found".

下面是我的code：

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {                  

            return new PasswordAuthentication("myUsername", "myPassword".toCharArray());
    }               
});

URL url = new URL(myUrl);               
HttpURLConnection conn = (HttpURLConnection) url.openConnection();          

conn.setRequestMethod("GET");
conn.setRequestProperty("Accept-Encoding", "gzip");
conn.setRequestProperty("Accept-Charset", "UTF-8");         
conn.setRequestProperty("Accept", "*/*");
conn.setRequestProperty("Connection", "close");
conn.setDoOutput(true);
conn.setDoInput(true);          

try 
{   
    conn.connect();             
    status_code = conn.getResponseCode();   
}catch (IOException e) {
    ...             
}

我真的开始觉得NTLM挑战是不支持的HttpURLConnection。我看到一些图书馆似乎做的工作，但我想preFER不使用外部库。

I'm really starting to think that NTLM challenge is just not supported by HttpUrlConnection. I saw some libraries that seems to do the work, but I would prefer not to use external libraries.

有人可以确认是否是可以或不可以做的HttpURLConnection手柄NTLM挑战，而无需外部库？

Can somebody confirm if it is possible or not to make HttpUrlConnection handle NTLM challenge without external libs?

推荐答案

我只能够使通过设置AuthScheme及以下的图书馆用HttpClient的工作： http://jcifs.samba.org/src/jcifs-krb5-1.3.17.zip 。

I've only been able to make it work with HttpClient by setting the AuthScheme and the library below: http://jcifs.samba.org/src/jcifs-krb5-1.3.17.zip.

HttpClient httpclient = new HttpClient(httpParameters, context);
NTCredentials creds = new NTCredentials("username", "password", "", "dir");
httpclient.getCredentialsProvider().setCredentials(
              new AuthScope(context.getString("whatever is your main URL"), -1), creds);
httpclient.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());

然后你实现了JCIFS发动机和工厂。您可以在 http://hc.apache.org/httpcomponents-样本客户4.2.x版/ ntlm.html
