6、对原生http的简易封装
6.1 HttpCall http 请求结果的实体类
package www.yiba.com.analytics.http; /**
* Created by ${zyj} on 2016/8/18.
*/
public class HttpCall { private ResponseType httpQuestType ;
private String result ; public ResponseType getHttpQuestType() {
return httpQuestType;
} public void setHttpQuestType(ResponseType httpQuestType) {
this.httpQuestType = httpQuestType;
} public String getResult() {
return result;
} public void setResult(String result) {
this.result = result;
}
}
6.2 ResponseType http 请求结果的类型
package www.yiba.com.analytics.http; /**
* Created by ${zyj} on 2016/8/18.
*/
public enum ResponseType { OK("请求成功") , FAIL("请求失败") , TIMEOUT("请求超时") ; private String name ; private ResponseType(String name ){
this.name = name ;
} public String getName() {
return name;
}
}
6.3 HttpUtil 包含 get 和 post请求
package www.yiba.com.analytics.http; import android.os.Build; import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection; import javax.net.ssl.HttpsURLConnection; public class HttpUtil { private static final int TIMEOUT_IN_MILLIONS = 25000; /**

}
if (responseCode == 200) {

HttpCall httpCall = new HttpCall() ; try {

//打开和URL之间的连接

//设置通用的请求属性
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("Content-Type",
"application/json");

String line;
while ((line = in.readLine()) != null) {

} if ( callback != null ){

httpCall.setHttpQuestType( ResponseType.OK );

finally {
try {

in.close();
}
} catch (IOException ex) {
ex.printStackTrace();
}
if (conn != null) {
if (url.toLowerCase().startsWith("https")) {

} else {
((HttpURLConnection) conn).disconnect();
}
}
return httpCall ;
}
} public interface Callback{
void ok(String result) ;
void fail();
void timeOut() ;
} }
6.4 如何使用
private void httpGet(){
//get 用法1
new Thread(new Runnable() {
@Override
public void run() {
HttpUtil.doGet("http://www.baidu.com", new HttpUtil.Callback() {
@Override
public void ok(String result) {
//请求成功
}
@Override
public void fail() {
//请求失败
}
@Override
public void timeOut() {
//请求超时
}
}) ;
}
}) ;
//get 用法2
new Thread(new Runnable() {
@Override
public void run() {
HttpCall httpCall = HttpUtil.doGet( "http://www.baidu.com" , null ) ;
switch ( httpCall.getHttpQuestType() ){
case OK:
//请求成功
break;
case FAIL:
//请求失败
break;
case TIMEOUT:
//请求超时
break;
}
}
}) ;
}
private void httpPost(){
//post 用法1
new Thread(new Runnable() {
@Override
public void run() {
HttpUtil.doPost("http://www.baidu.com", "post请求参数" , new HttpUtil.Callback() {
@Override
public void ok(String result) {
//请求成功
}
@Override
public void fail() {
//请求失败
}
@Override
public void timeOut() {
//请求超时
}
}) ;
}
}) ;
//post 用法2
new Thread(new Runnable() {
@Override
public void run() {
HttpCall httpCall = HttpUtil.doPost( "http://www.baidu.com" , "post请求参数" , null ) ;
switch ( httpCall.getHttpQuestType() ){
case OK:
//请求成功
break;
case FAIL:
//请求失败
break;
case TIMEOUT:
//请求超时
break;
}
}
}) ;
}
7、http下载图片并且压缩bitmap
//从网络下载bitmap
private Bitmap downLoadBitmapFromNet( String urlString ){
InputStream inputStream = null ;
HttpURLConnection conn = null ;
Bitmap bitmap ;
try {
URL url = new URL( urlString ) ;
conn = (HttpURLConnection) url.openConnection();
inputStream = new BufferedInputStream( conn.getInputStream() ) ; inputStream.mark( inputStream.available() ); //压缩图片
BitmapFactory.Options options = new BitmapFactory.Options() ;
options.inJustDecodeBounds = true ;
BitmapFactory.decodeStream( inputStream , null , options ) ;
options.inSampleSize = 4 ;
options.inPreferredConfig = Bitmap.Config.RGB_565 ;
options.inJustDecodeBounds = false ; inputStream.reset();
bitmap = BitmapFactory.decodeStream( inputStream , null , options ) ; return bitmap ;
} catch (MalformedURLException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}finally {
if ( inputStream != null ){
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if ( conn != null ){
conn.disconnect();
}
}
return null ;
}
需要注意的事项
1、并不是所有的inputStream都支持mark()方法的, 因为这里的 InputStream其实是 BufferedInputStream 。 BufferedInputStream 继承 InputStream 并且重写了里面的 mark() 、reset（） 、markSupported()
