具有基本身份验证结果的HTTPS连接进入未授权

Question

我正在尝试通过以下方式从我的Android / Java源代码访问Basecamp
API
。

import org.apache.http.HttpResponse;
import org.apache.http.StatusLine;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class BCActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        DefaultHttpClient httpClient = new DefaultHttpClient();

        //final String url = "https://encrypted.google.com/webhp?hl=en"; //This url works
        final String url = "https://username:[e-mail]/people.xml"; //This don't
        HttpGet http = new HttpGet(url);
        http.addHeader("Accept", "application/xml");
        http.addHeader("Content-Type", "application/xml");

        try {

            //  HttpResponse response = httpClient.execute(httpPost);
            HttpResponse response = httpClient.execute(http);

            StatusLine statusLine = response.getStatusLine();
            System.out.println("statusLine : "+ statusLine.toString());

            ResponseHandler <String> res = new BasicResponseHandler();

            String strResponse = httpClient.execute(http, res);
            System.out.println("________**_________________________\n"+strResponse);
            System.out.println("\n________**_________________________\n");

        } catch (Exception e) {
            e.printStackTrace(); 
        }

        WebView myWebView = (WebView) this.findViewById(R.id.webView);
        myWebView.loadUrl(url);//Here it works and displays XML response

    }
}

该URL在中显示了响应WebView，但是当我尝试HttpClient如上所述访问时，显示了未经授权的异常。

这是通过Android / Java 访问 Basecamp API的 正确方法吗？或请提供给我正确的方法。

Answer 1

该 HttpClient的 不能把从URI登录creditals。
您必须给他们指定的方法。

如果您使用 HttpClient 4.x，请查看以下内容：http :
//hc.apache.org/httpcomponents-client-
ga/tutorial/html/authentication.html

但是请注意，如果您不想在 HttpClient

上使用新版本（Android使用版本3.x），则应在此处查看： http

//hc.apache.org/httpclient-3.x/authentication.html

这就是理论，现在我们使用它们：
基本上，我们使用 HTTP ，但是如果要使用 HTTPS ，则必须将以下分配编辑new HttpHost("www.google.com", 80, "http")为new HttpHost("www.google.com", 443, "https")。

此外，您还必须针对您的问题编辑主机（ www.google.com ）。
注意： 仅需要完整的合格域名（FQDN），而不需要完整的URI。

HttpClient 3.x：

package com.test;

import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import android.app.Activity;
import android.os.Bundle;

public class Test2aActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
            HttpHost targetHost = new HttpHost("www.google.com", 80, "http");

            DefaultHttpClient httpclient = new DefaultHttpClient();
            try {
                // Store the user login
                httpclient.getCredentialsProvider().setCredentials(
                        new AuthScope(targetHost.getHostName(), targetHost.getPort()),
                        new UsernamePasswordCredentials("user", "password"));

                // Create request
                // You can also use the full URI http://www.google.com/
                HttpGet httpget = new HttpGet("/");
                // Execute request
                HttpResponse response = httpclient.execute(targetHost, httpget);

                HttpEntity entity = response.getEntity();
                System.out.println(EntityUtils.toString(entity));
            } finally {
                httpclient.getConnectionManager().shutdown();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

HttpClient 4.x：

注意： 您将需要来自Apache 的新 HttpClient ，并且还必须重新排列顺序，即jar文件位于Android库之前。

package com.test;

import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.AuthCache;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.protocol.ClientContext;
import org.apache.http.impl.auth.BasicScheme;
import org.apache.http.impl.client.BasicAuthCache;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.protocol.BasicHttpContext;
import org.apache.http.util.EntityUtils;
import android.app.Activity;
import android.os.Bundle;

public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
            HttpHost targetHost = new HttpHost("www.google.com", 80, "http");

            DefaultHttpClient httpclient = new DefaultHttpClient();
            try {
                // Store the user login
                httpclient.getCredentialsProvider().setCredentials(
                        new AuthScope(targetHost.getHostName(), targetHost.getPort()),
                        new UsernamePasswordCredentials("user", "password"));

                // Create AuthCache instance
                AuthCache authCache = new BasicAuthCache();
                // Generate BASIC scheme object and add it to the local
                // auth cache
                BasicScheme basicAuth = new BasicScheme();
                authCache.put(targetHost, basicAuth);

                // Add AuthCache to the execution context
                BasicHttpContext localcontext = new BasicHttpContext();
                localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);

                // Create request
                // You can also use the full URI http://www.google.com/
                HttpGet httpget = new HttpGet("/");
                // Execute request
                HttpResponse response = httpclient.execute(targetHost, httpget, localcontext);

                HttpEntity entity = response.getEntity();
                System.out.println(EntityUtils.toString(entity));
            } finally {
                httpclient.getConnectionManager().shutdown();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
