Android学习记录（十二) http之base/digest鉴权。

说下背景，我们实现的http的文件下载是基于webdav协议的。这个肯定是需要鉴权的～android 5.1不再推荐使用apache的client,今天努力想尝试一下用httpurlconnection替换一下。大家可以到stackoverflow搜索一下，目前httpurlconnection还不支持digest鉴权，只支持base的鉴权。下面是httpurlconnection base的鉴权代码：

HttpURLConnection conn=(HttpURLConnection)newurl.openConnection();
setJellyBeanAuth(conn);

private void setJellyBeanAuth(HttpURLConnection httpConn) {
byte[] auth = (LoginManager
.getCurrentUsername() + ":" + LoginManager
.getCurrentPassword()).getBytes();
String basic = Base64.encodeToString(auth, Base64.NO_WRAP);
httpConn.setRequestProperty("Authorization", "Basic " + basic);
}

然后偶们需要的是digest鉴权，所以还的老老实实使用httpclient

digest的鉴权代码如下：

HttpContext context = new BasicHttpContext();context.setAttribute(ClientContext.CREDS_PROVIDER,new BasicCredentialsProvider());CredentialsProvider provider = (CredentialsProvider) context.getAttribute(ClientContext.CREDS_PROVIDER);provider.setCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()),new UsernamePasswordCredentials(LoginManager.getCurrentUsername(), LoginManager.getCurrentPassword()));

关于httpurlconnection不支持digest的可以看这篇文章：
