转 Android-使用单例模式实现自己的HttpClient工具类

publicclassCustomerHttpClient{

privatestaticfinalStringCHARSET=HTTP.UTF_8;

privatestaticHttpClientcustomerHttpClient;

privateCustomerHttpClient(){

}

publicstaticsynchronizedHttpClientgetHttpClient(){

if(null==customerHttpClient){

HttpParamsparams=newBasicHttpParams();

//设置一些基本参数

HttpProtocolParams.setVersion(params,HttpVersion.HTTP_1_1);

HttpProtocolParams.setContentCharset(params,

CHARSET);

HttpProtocolParams.setUseExpectContinue(params,true);

HttpProtocolParams

.setUserAgent(

params,

"Mozilla/5.0(Linux;U;Android2.2.1;en-us;NexusOneBuild.FRG83)"

+"AppleWebKit/553.1(KHTML,likeGecko)Version/4.0MobileSafari/533.1");

//超时设置

/*从连接池中取连接的超时时间*/

ConnManagerParams.setTimeout(params,1000);

/*连接超时*/

HttpConnectionParams.setConnectionTimeout(params,2000);

/*请求超时*/

HttpConnectionParams.setSoTimeout(params,4000);

//设置我们的HttpClient支持HTTP和HTTPS两种模式

SchemeRegistryschReg=newSchemeRegistry();

schReg.register(newScheme("http",PlainSocketFactory

.getSocketFactory(),80));

schReg.register(newScheme("https",SSLSocketFactory

.getSocketFactory(),443));

//使用线程安全的连接管理来创建HttpClient

ClientConnectionManagerconMgr=newThreadSafeClientConnManager(

params,schReg);

customerHttpClient=newDefaultHttpClient(conMgr,params);

}

returncustomerHttpClient;

}

}
