错误＆QUOT; HTTP / 1.1 401未经授权＆QUOT;在Android的基本身份验证 - EWS 2010 [英] Error "HTTP/1.1 401 Unauthorized" with basic authentication in android - EWS 2010

问题描述

我指的是此链接请求到服务器。问题是有时（并不总是，约20％ - 30％，这意味着有时我能得到成功响应），我得到了401错误和服务器响应的基本授权挑战预期，但没有找到的

下面是我的code：

 的Htt prequestInterceptor preemptiveAuth =新的Htt prequestInterceptor（）
{
    公共无效过程（最终的Htt prequest的要求，最终HttpContext的背景下）
            抛出HttpException，IOException异常
    {
        AuthState authState =（AuthState）上下文
                .getAttribute（ClientContext.TARGET_AUTH_STATE）;
        CredentialsProvider credsProvider =（CredentialsProvider）上下文
                .getAttribute（ClientContext.CREDS_PROVIDER）;
        HttpHost targetHost =（HttpHost）上下文
                .getAttribute（ExecutionContext.HTTP_TARGET_HOST）;

        如果（authState.getAuthScheme（）== NULL）
        {
            AuthScope authScope =新AuthScope（targetHost.getHostName（）
                    targetHost.getPort（））;
            凭据creds = credsProvider.getCredentials（authScope）;
            如果（creds！= NULL）
            {
                authState.setAuthScheme（新BasicScheme（））;
                authState.setCredentials（creds）;
            }
        }
    }
};
 

下面是我的身份验证：

  HttpPost httpPost =新HttpPost（SERVER_AUTH_URL）;
        httpPost.setHeader（内容型，为text / xml;字符集= UTF-8）;
    httpPost.setHeader（保持活跃，300）;
    httpPost.setHeader（连接，保持活动）;
    StringEntity本身=新StringEntity（myRequest，UTF-8）;
    httpPost.setEntity（SE）;
    se.setContentType（为text / xml）;
    se.setContentEncoding（gzip压缩，放气）;

        //增加preemptiveAuth
        client.addRequestInterceptor（preemptiveAuth，0）;
        //设置代理
    ProxySelectorRoutePlanner routePlanner =新ProxySelectorRoutePlanner（
            client.getConnectionManager（）。getSchemeRegistry（），
            ProxySelector.getDefault（））;
    client.setRoutePlanner（routePlanner）;

    名单＆LT;字符串＆GT; AUTH preFS =新的ArrayList＆LT;字符串＆GT;（）;
    AUTH prefs.add（AuthPolicy.BASIC）;
    AUTH prefs.add（AuthPolicy.NTLM）;
    AUTH prefs.add（AuthPolicy.DIGEST）;
    client.getParams（）的setParameter（http.auth.scheme优先，权威性preFS）。
    CredentialsProvider credProvider =新BasicCredentialsProvider（）;
    // client.getParams（）的setParameter（http.auth.scheme优先，
    // AUTH preFS）;
    credProvider.setCredentials（AuthScope.ANY，
            新NTCredentials（getUsername（），getPassword来（），
                    ，getDomain（）））;

    Log.d（TAG，修EXCUTE）;
    client.setCredentialsProvider（credProvider）;
    HTT presponse响应= client.execute（httpPost）;
    Log.d（TAG，有EXCUTE）;
 

在注释code，你可以看到我尝试过很多办法，但错误没有消失。这是logcat的说：

那么，请告诉我，是我的问题。在此先感谢。
更新：目标服务器的Exchange Web服务的2010年。出于某种原因，我不希望使用EWS API的，我做我自己的XML请求连接到服务器（此XML请求正常工作） 。

解决方案

我基本上周挣扎与Android HTTP。我试过，也许3或4个不同的做这件事的方式，总是我发现了一些问题。现在唯一的办法我设法使它工作是最简单的方法。

  UsernamePasswordCredentials凭据=新UsernamePasswordCredentials（user和pass）;
 标题标题=新BasicScheme（）认证（证书，mHtt prequest）。
 mHtt prequest.addHeader（头）;
 

这对我来说曾与AndroidHttpClient。

这是基于 <一href="http://luken$c$c.com/2010/04/27/calling-web-services-in-android-using-httpclient/">http://luken$c$c.com/2010/04/27/calling-web-services-in-android-using-httpclient/

I refer to this link to request to the server. The problem is sometime (not always, about 20% - 30%, means sometime I can get successful response), I got the 401 error and server response basic authorization challenge expected, but not found.

Here is my code:

 HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor()
{
    public void process(final HttpRequest request, final HttpContext context)
            throws HttpException, IOException
    {
        AuthState authState = (AuthState) context
                .getAttribute(ClientContext.TARGET_AUTH_STATE);
        CredentialsProvider credsProvider = (CredentialsProvider) context
                .getAttribute(ClientContext.CREDS_PROVIDER);
        HttpHost targetHost = (HttpHost) context
                .getAttribute(ExecutionContext.HTTP_TARGET_HOST);

        if (authState.getAuthScheme() == null)
        {
            AuthScope authScope = new AuthScope(targetHost.getHostName(),
                    targetHost.getPort());
            Credentials creds = credsProvider.getCredentials(authScope);
            if (creds != null)
            {
                authState.setAuthScheme(new BasicScheme());
                authState.setCredentials(creds);
            }
        }
    }
};

Here is my authentication:

    HttpPost httpPost = new HttpPost(SERVER_AUTH_URL);
        httpPost.setHeader("Content-type", "text/xml; charset=utf-8");
    httpPost.setHeader("Keep-Alive", "300");
    httpPost.setHeader("Connection", "Keep-Alive");     
    StringEntity se = new StringEntity(myRequest, "UTF-8");
    httpPost.setEntity(se);
    se.setContentType("text/xml");
    se.setContentEncoding("gzip,deflate");

        //add preemptiveAuth
        client.addRequestInterceptor(preemptiveAuth, 0);
        //Set the proxy
    ProxySelectorRoutePlanner routePlanner = new ProxySelectorRoutePlanner(
            client.getConnectionManager().getSchemeRegistry(),
            ProxySelector.getDefault());
    client.setRoutePlanner(routePlanner);

    List<String> authPrefs = new ArrayList<String>();
    authPrefs.add(AuthPolicy.BASIC);
    authPrefs.add(AuthPolicy.NTLM);
    authPrefs.add(AuthPolicy.DIGEST);
    client.getParams().setParameter("http.auth.scheme-priority", authPrefs);
    CredentialsProvider credProvider = new BasicCredentialsProvider();                 
    // client.getParams().setParameter("http.auth.scheme-priority",
    // authPrefs);
    credProvider.setCredentials(AuthScope.ANY,
            new NTCredentials(getUsername(), getPassword(),
                    "", getDomain()));

    Log.d(TAG, "repair excute");
    client.setCredentialsProvider(credProvider);
    HttpResponse response = client.execute(httpPost);
    Log.d(TAG, "has excute");

From the comment code, you can see I tried many ways, but the error wasn't disappear. Here is logcat say:

 05-02 10:28:23.124: E/MainActivity(1169): response error: HTTP/1.1 401 Unauthorized

So, please tell me where is my problem. Thanks in advance.
Update: the target server is Exchange Web Service 2010. For some reason, I don't want to use EWS API, I made my own xml request to connect to the server (this xml request works properly).
And here is the response header from server When request failed:

Server   Microsoft-IIS/7.5

WWW-Authenticate   NTLM

When request success the first time:

The cookie is my problem, isn't it?

解决方案

I was struggling with Android HTTP basic last week. I have tried maybe 3 or 4 different ways of doing it and always I found some problem. Right now the only way I managed to make it work was the simplest way.

 UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(user, pass);
 Header header = new BasicScheme().authenticate(credentials, mHttpRequest);
 mHttpRequest.addHeader(header);

That worked for me with AndroidHttpClient.
