需要帮助为Android创建摘要式身份验证 [英] Need help creating Digest authentication for Android

问题描述

我有这个code到目前为止：

I have this code so far:

private class DownloadWebPageTask extends AsyncTask<String, Void, String> 
{
        @Override
        protected String doInBackground(String... theParams) 
        {
            String myUrl = theParams[0];
            String myEmail = theParams[1];
            String myPassword = theParams[2];

            HttpPost post = new HttpPost(myUrl);
            post.addHeader("Authorization","Basic "+ Base64.encodeToString((myEmail+":"+myPassword).getBytes(), 0 ));
            ResponseHandler<String> responseHandler = new BasicResponseHandler();

            String response = null;

            try 
            {
                    response = client.execute(post, responseHandler);
                InputStream content = execute.getEntity().getContent();

                BufferedReader buffer = new BufferedReader(
                            new InputStreamReader(content));
                    String s = "";
                    while ((s = buffer.readLine()) != null) 
                    {
                        response += s;
                    }
                } 
                catch (Exception e) 
                {
                    e.printStackTrace();
                }

            return response;
        }


        @Override
        protected void onPostExecute(String result) 
        {
            }

}

这code不能编译，因为我在的点上运行陷入混乱：

This code does not compile because I am running into confusion at the point of:

                response = client.execute(post, responseHandler);
                InputStream content = execute.getEntity().getContent();

我得到的code，从各种例子修修补补，而且不知道什么对象的客户端应该是，第一行是否会帮我买服务器的响应，否则我得去获取途径在InputStream和读取服务器的响应？

I got that code from tinkering with various examples, and not sure what Object the client is supposed to be, and whether the first line will just get me the server response, or I have to go the route of getting the InputStream and reading the server response in?

请帮助我了解如何正确地做到这一点。

Please help me understand how to do this correctly.

感谢您！

推荐答案

您可能要切换到的 的HttpURLConnection 。据这篇文章其API比<$简单C $ C>的HttpClient 的而且最好在Android的支持。如果你选择去与的HttpURLConnection ，认证为pretty的简单：

You might want to switch to HttpURLConnection. According to this article its API is simpler than HttpClient's and it's better supported on Android. If you do choose to go with HttpURLConnection, authenticating is pretty simple:

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("username", "password".toCharArray());
    }
});

在此之后，继续使用的HttpURLConnection 如常。一个简单的例子：

After that, continue using HttpURLConnection as usual. A simple example:

final URL url = new URL("http://example.com/");
final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
final InputStream is = conn.getInputStream();
final byte[] buffer = new byte[8196];
int readCount;
final StringBuilder builder = new StringBuilder();
while ((readCount = is.read(buffer)) > -1) {
    builder.append(new String(buffer, 0, readCount));
}
final String response = builder.toString();
