android与Web服务器交互时的cookie使用实例

public static String getRequest1(String url, DefaultHttpClient client,

// 添加用户密码验证信息

// client.getCredentialsProvider().setCredentials(

// new AuthScope(null, -1),

// new UsernamePasswordCredentials(mUsername, mPassword));

HttpResponse httpResponse = client.execute(getMethod);

// statusCode == 200 正常

statusCode = httpResponse.getStatusLine().getStatusCode();

// 处理返回的httpResponse信息
