关于HttpClient的总结（一）       java中Logger.getLogger 

HttpClient.class

 /**
  * Bad Request: The request was invalid. An accompanying error message will
  * explain why. This is the status code will be returned during rate
  * limiting.
  * (Rate Limiting):对数据包进行修整。防止不正常数据包攻击目标,
  * 对每个数据流业务进行修整,处罚长时间消耗大量资源的源头。
  */
 public static final int BAD_REQUEST = 400;

 

 /**
  * Service Unavailable: The Weibo servers are up, but overloaded with
  * requests. Try again later. The search and trend methods use this to
  * indicate when you are being rate limited.
  */
 public static final int SERVICE_UNAVAILABLE = 503;

 包含的参数

/**The class represents an authentication scope consisting of a host
 name, a port number, a realm name and an authentication scheme 
name which Credentials apply to.*/
private AuthScope mAuthScope

private DefaultHttpClient mClient;
private BasicHttpContext localcontext;
private String mUserId;
private String mPassword;
private OAuthClient mOAuthClient;
private String mOAuthBaseUrl = Configuration.getOAuthBaseUrl();

简述Configuration.class

 

 public class Configuration {
   private static Properties defaultProperty;
 static {
  init();
 }
 /* package */static void init() {
       defaultProperty.setProperty("fanfoudroid.oauth.baseUrl","http://fanfou.com/oauth");
....
通过public static String getOAuthBaseUrl() {
  return getProperty("fanfoudroid.oauth.baseUrl");
 }
    public static String getProperty(String name) {
  return getProperty(name, null);
 }
//fallbackValue当没有这个property时被返回值
   public static String getProperty(String name, String fallbackValue) {
  String value;
  try {
   value = System.getProperty(name, fallbackValue);
   if (null == value) {
//从自定义默认的Property取值
    value = defaultProperty.getProperty(name);
 
//从系统取值
.....
     value = System.getProperty(fallback);
.....
  } catch (AccessControlException ace) {
  // Unsigned applet cannot access System properties
   value = fallbackValue;
  }
//去掉value里面包含{ }..用到substring,indexof..不做介绍
  return replace(value);
 }

 HttpClient.class 的无参构造类

//设置日志输出
// Create and initialize HTTP parameters
// Create and initialize scheme registry
// Create an HttpClient with the ThreadSafeClientConnManager.
// Support GZIP

public HttpClient() {

 prepareHttpClient();
/**
     * Sets the consumer key and consumer secret.<br>
     */
 setOAuthConsumer(null, null, null);
}

 

//设置日志输出
private void enableDebug() {
  Log.d(TAG, "enable apache.http debug");

  java.util.logging.Logger.getLogger("org.apache.http").setLevel(
    java.util.logging.Level.FINEST);
  java.util.logging.Logger.getLogger("org.apache.http.wire").setLevel(

  java.util.logging.Logger.getLogger("org.apache.http.headers").setLevel(
