// 设置重定向,缺省为 true
HttpClientParams.setRedirecting(params, true);
// 设置 user agent
HttpProtocolParams.setUserAgent(params, userAgent);
// 创建一个 HttpClient 实例
// 注意 HttpClient httpClient = new HttpClient(); 是Commons HttpClient
// 中的用法,在 Android 1.5 中我们需要使用 Apache 的缺省实现 DefaultHttpClient
HttpClient httpClient = new DefaultHttpClient(params);
// 创建 HttpGet 方法,该方法会自动处理 URL 地址的重定向
HttpGet httpGet = new HttpGet ("http://www.test_test.com/");
HttpResponse response = client.execute(httpGet);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
// 错误处理,例如可以在该请求正常结束前将其中断
httpGet.abort();
}
// 读取更多信息
Header[] headers = response.getHeaders();
HttpEntity entity = response.getEntity();
Header header = response.getFirstHeader("Content-Type");
} catch (Exception ee) {
//
} finally {
// 释放连接
client.getConnectionManager().shutdown();
}
以下例子以 HttpGet 方式通过代理访问 HTTPS 网站:
try {
HttpClient httpClient = new HttpClient();
// 设置认证的数据
httpClient.getCredentialsProvider().setCredentials(
new AuthScope("your_auth_host", 80, "your_realm"),
new UsernamePasswordCredentials("username", "password"));
// 设置服务器地址,端口,访问协议
HttpHost targetHost = new HttpHost("www.test_test.com", 443, "https");
// 设置代理
HttpHost proxy = new HttpHost("192.168.1.1", 80);
httpClient.getParams().setParameter
(ConnRoutePNames.DEFAULT_PROXY, proxy);
// 创建一个 HttpGet 实例
