Android-为摘要身份验证配置改型/Apache HttpClient

我正在从事一个Android项目，并试图获得摘要认证，以便进行改造。我有点惊讶于改型并没有在本机上支持它（或者更准确地说，OkHttp不支持它），但我想抱怨是没有意义的

我在这里浏览了很多线程，似乎正确的解决方案是将ApacheHttpClient（本机支持DigestAuth）与改型集成在一起。这需要使用改装的.client.client实现包装HttpClient。必须解析改装输入值并将其内置到新的HttpClient响应中，然后将其发送回改装以正常处理。感谢Jason Tu和他的例子：

问题是，它不起作用。我每次都会得到一份未经授权的401，但我不清楚为什么。这是我的客户impl：

public class AuthClientRedirector implements Client {
    private final CloseableHttpClient delegate;

    public AuthClientRedirector(String user, String pass, String hostname, String scope) {
        Credentials credentials = new UsernamePasswordCredentials(user, pass);
        AuthScope authScope = new AuthScope(hostname, 443, scope);

        CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(authScope, credentials);

        delegate = HttpClientBuilder.create()
        .setDefaultCredentialsProvider(credentialsProvider)
        .build();
   }

    @Override 
    public Response execute(Request request) {
    //
    // We're getting a Retrofit request, but we need to execute an Apache
    // HttpUriRequest instead. Use the info in the Retrofit request to create
    // an Apache HttpUriRequest.
    //
    String method = request.getMethod();

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    if (request.getBody() != null) {
        try {
            request.getBody().writeTo(bos);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    String body = new String(bos.toByteArray());

    HttpUriRequest wrappedRequest;
    switch (method) {
    case "GET":
        wrappedRequest = new HttpGet(request.getUrl());
        break;
    case "POST":
        wrappedRequest = new HttpPost(request.getUrl());
        wrappedRequest.addHeader("Content-Type", "application/xml");
        try {
            ((HttpPost) wrappedRequest).setEntity(new StringEntity(body));
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        break;
    case "PUT":
        wrappedRequest = new HttpPut(request.getUrl());
        wrappedRequest.addHeader("Content-Type", "application/xml");
        try {
            ((HttpPut) wrappedRequest).setEntity(new StringEntity(body));
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        break;
    case "DELETE":
        wrappedRequest = new HttpDelete(request.getUrl());
        break;
    default:
        throw new AssertionError("HTTP operation not supported.");
    }

CloseableHttpResponse apacheResponse = null;
try {
    apacheResponse = delegate.execute(wrappedRequest);
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

if(apacheResponse!=null){
    // Perform the HTTP request.
    CloseableHttpResponse response = null;
    try {
        response = delegate.execute(wrappedRequest);

        // Return a Retrofit response.
        List<Header> retrofitHeaders = toRetrofitHeaders(
                response.getAllHeaders());
        TypedByteArray responseBody;
        if (response.getEntity() != null) {
            responseBody = new TypedByteArray("",
                    toByteArray(response.getEntity()));
        } else {
            responseBody = new TypedByteArray("",
                    new byte[0]);
        }
        System.out.println("this is the response");
        System.out.println(new String(responseBody.getBytes()));
        return new retrofit.client.Response(request.getUrl(),
                response.getStatusLine().getStatusCode(),
                response.getStatusLine().getReasonPhrase(), retrofitHeaders,
                responseBody);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block

    } catch (IOException e) {
        // TODO Auto-generated catch block

            }

    //failed to return a new retrofit Client
    return null;

    List<Header> retrofitHeaders = new ArrayList<>();
    for (org.apache.http.Header header : headers) {
        retrofitHeaders.add(new Header(header.getName(), header.getValue()));
    }
    return retrofitHeaders;

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    entity.writeTo(bos);
    return bos.toByteArray();

我被难倒了，为什么我总是从服务器返回401。我已经走过了建立响应的过程，在我看来它是干净的，所以我认为我遗漏了一些基本的东西。凭据是好的，我已经在应用程序外部验证了它们。以前有人走过这条路吗？

您正在使用端口号443进行身份验证

AuthScope authScope = new AuthScope(hostname, 443, scope);

但是，您的实际端口号似乎是8003

RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint("http://myhostname:8003/endpoint")

那么，使用端口号8003进行身份验证如何

AuthScope authScope = new AuthScope(hostname, 8003, scope);

AuthScope authScope = new AuthScope(hostname, 8003, scope);
