封装HTTP请求-优快云博客

1、封装String字符串

private static void request(String url,final Callback callback){
		
		final Handler handler =new Handler(){
			@Override
			public void handleMessage(Message msg) {
				super.handleMessage(msg);
				String result=(String) msg.obj;
				if(result!=null && !"".equals(result)){
					callback.onCallback(result);
				}
			}
		};
		final OkHttpClient mOkHttpClient=new OkHttpClient();
		final Request request=new Request.Builder().url(url).get().build();
		
		try {
			new Thread(new Runnable() {
				
				@Override
				public void run() {
					Response response;
					try {
						response = mOkHttpClient.newCall(request).execute();
						if(response.isSuccessful()){
							Message message=new Message();
							message.obj=response.body().string();
							handler.sendMessage(message);
						}
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}).start();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

通过get方式获取:

	public static void getUserInfo(String access_token,String openid,Callback<String> callback){
		String url="https://api.weixin.qq.com/sns/userinfo?access_token="+access_token+"&openid="+openid+"";
		request(url,callback);
	}

调用的执行的方法:

Httpget.getUserInfo(access_token,openid,new Callback<String>() {

		@Override
		public void onCallback(String result) {
			// 在这里处理你的回调结果
		}
	});
}

回调接口:

package com.example.testweixinshare;

public interface Callback<T> {

	 public void onCallback(final T result);
	  
}

2、封装Bitmap对象

private static void requestBitmap(String url,final Callback callback){
		
		final Handler handler =new Handler(){
			@Override
			public void handleMessage(Message msg) {
				super.handleMessage(msg);
				Bitmap result=(Bitmap) msg.obj;
				if(result!=null && !"".equals(result)){
					callback.onCallback(result);
				}
			}
		};
		final OkHttpClient mOkHttpClient=new OkHttpClient();
		final Request request=new Request.Builder().url(url).get().build();
		
		try {
			new Thread(new Runnable() {
				
				@Override
				public void run() {
					Response response;
					try {
						response = mOkHttpClient.newCall(request).execute();
						if(response.isSuccessful()){
							InputStream inputStream=response.body().byteStream();
							Bitmap bitmap=BitmapFactory.decodeStream(inputStream);
							Message message=new Message();
							message.obj=bitmap;
							handler.sendMessage(message);
						}
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}).start();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

通过get方式获取:

public static void getHeadImgUrl(String url,final Callback<Bitmap> callback){
		requestBitmap(url,callback);
	}

调用的执行的方法:

 Httpget.getHeadImgUrl(headimgurl, new Callback<Bitmap>() {
										
	@Override
	public void onCallback(Bitmap result) {
		iv_head_portrait.setImageBitmap(result);  
	}
});

3、Post封装String字符串

public static void postRequest(String url,final Callback callback){
		
		final Handler handler =new Handler(){
			@Override
			public void handleMessage(Message msg) {
				super.handleMessage(msg);
				String result=(String) msg.obj;
				if(result!=null && !"".equals(result)){
					callback.onCallback(result);
				}
			}
		};
		
		final OkHttpClient mOkHttpClient=new OkHttpClient();
		
		String xml="<xml><appid>appid</appid><attach>支付测试</attach><body>APP支付测试</body><mch_id>10000100</mch_id><nonce_str>1add1a30ac87aa2db72f57a2375d8fec</nonce_str><notify_url>http://wxpay.weixin.qq.com/pub_v2/pay/notify.v2.php</notify_url><out_trade_no>1415659990</out_trade_no><spbill_create_ip>14.23.150.211</spbill_create_ip><total_fee>1</total_fee><trade_type>APP</trade_type><sign>0CB01533B8C1EF103065174F50BCA001</sign></xml>";
		
		RequestBody body=RequestBody.create(MediaType.parse("application/octet-stream"), xml.getBytes());
	
		final Request request=new Request.Builder().url(url).post(body).build();
		
		try {
			new Thread(new Runnable() {
				
				@Override
				public void run() {
					Response response;
					try {
						response = mOkHttpClient.newCall(request).execute();
						if(response.isSuccessful()){
							Message message=new Message();
							message.obj=response.body().string();
							handler.sendMessage(message);
						}
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}).start();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

调用的执行的方法:

Httpget.postRequest("https://api.mch.weixin.qq.com/pay/unifiedorder", new Callback<String>() {

			@Override
			public void onCallback(String result) {
				Log.i("Result", result);
			}
		});
