请问, 如何在Android终端实现Http的摘要(Digest)认证, 到网上搜了下, 都说的很笼统, 有没找到相关的API. 请高人指教.
------解决方案--------------------
我搜了一下资料，我没有自己实践过，还需要你亲自验证一下才好
基本思路：
--- 使用HttpClient(DefaultHttpClient)类连接服务器并获取数据
DefualtHttpClient 类：创建client对象
excuete(HttpGet)方法：执行连接和获取，参数是一个HttpGet对象
HttpGet类：基于url创建HttpGet对象
HttpResponse类： execute的返回值
getEntiry().getContent() 方法：获取数据流
--- 该client访问需要认证的资源需要一个认证方法，就需要设置一个认证提供者
client的 setCredentialsProvider(bcp) 方法：设置认证提供者
BasicCredentialsProvider 类：创建认证提供者实例
setCredentials 方法：设置AuthScope和UsernamePasswordCredentials类
AuthScope类：认证范围，基于主机，端口和领域构建
UsernamePasswordCredentials：基于用户名和口令的证书，基于用户名和口令构建
- Java code
// 1. 获取并设置url地址，一个字符串变量，一个URL对象 String urlStr ="http://<host>:<port>/data.json";URL url= new URL(urlStr);// 2. 创建一个密码证书，(UsernamePasswordCredentials类) String username="foo"; String password="bar"; UsernamePasswordCredentials upc = new UsernamePasswordCredentials(username, password);// 3. 设置认证范围 (AuthScore类)String strRealm = "<mydomain>";String strHost = url.getHost();int iPort = url.getPort();AuthScope as = new AuthScope(strHost, iPort, strRealm);// 4. 创建认证提供者(BasicCredentials类) ，基于as和upcBasicCredentialsProvider bcp=new BasicCredentialsProvider();bcp.setCredentials(as, upc);// 5. 创建Http客户端(DefaultHttpClient类)DefaultHttpClient client=new DefaultHttpClient();// 6. 为此客户端设置认证提供者client.setCredentialsProvider(bcp);// 7. 创建一个get 方法(HttpGet类)，基于所访问的url地址HttpGet hg= new HttpGet(urlStr);// 8. 执行get方法并返回 responseHttpResponse hr = client.execute(hg);// 9. 从response中取回数据，使用InputStreamReader读取Response的Entity： String line=null; StringBuilder builder = new StringBuilder(); BufferedReader reader = new BufferedReader(new InputStreamReader(hr.getEntity().getContent() )); while((line = reader.readLine()) != null) builder.append(line); strContent=builder.toString();

- Java code
HttpGet httpRequest = new HttpGet(url); if(!name.equals("") || !password.equals("")) { String userPassword = name+":"+password; String encoding = Base64.encode(userPassword).trim(); httpRequest.addHeader("Authorization", "Basic " + encoding); } httpRequest.setHeader("User-agent", USER_AGENT); try { HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest); if(httpResponse.getStatusLine().getStatusCode()==200) { ret = EntityUtils.toString(httpResponse.getEntity()); }else { Log.e(TAG,"Fail: Code: " + httpResponse.getStatusLine().getStatusCode()); } httpRequest.abort(); }catch(IOException ex) { Log.e(TAG,ex.toString()); }
