开源项目方式提交数据-AsyncHttpClient

get提交

引用android-async-http-1.4.5.jar
	private static final int TIME_OUT = 5000;
	protected static final int TIME_OUT2 = 3000;
	private EditText et_text1;
	private EditText et_text2;
	private String PATH = "http://192.168.37.2:8080/http/loginServlet";
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		et_text1 = (EditText) findViewById(R.id.et_text1);
		et_text2 = (EditText) findViewById(R.id.et_text2);
	}
	
	//get提交
	public void click1(View view) throws Exception{
		
		final String username = et_text1.getText().toString().trim();
		final String password = et_text2.getText().toString().trim();
		
		if (TextUtils.isEmpty(username)&&TextUtils.isEmpty(password)) {
			Toast.makeText(this, "用户名和密码不能为空", Toast.LENGTH_SHORT).show();
			return;
		}
		
		AsyncHttpClient httpClient = new AsyncHttpClient();
		httpClient.get(PATH+"?username="+username+"&password="+password, new TextHttpResponseHandler() {
			
			@Override
			public void onSuccess(int statusCode, Header[] headers,
					String responseString) {
				Toast.makeText(MainActivity.this, "get方式提交成功："+username+"/"+password, Toast.LENGTH_SHORT).show();
			}
			
			@Override
			public void onFailure(int statusCode, Header[] headers,
					String responseString, Throwable throwable) {
				Toast.makeText(MainActivity.this, "post方式提交失败", Toast.LENGTH_SHORT).show();
			}
		});
		
	}

post提交

//post提交
	public void click2(View view){
		
		final String username = et_text1.getText().toString().trim();
		final String password = et_text2.getText().toString().trim();
		
		if (TextUtils.isEmpty(username)&&TextUtils.isEmpty(password)) {
			Toast.makeText(this, "用户名和密码不能为空", Toast.LENGTH_SHORT).show();
			return;
		}
		AsyncHttpClient httpClient = new AsyncHttpClient();
		RequestParams params = new RequestParams();
		params.add("username", username);
		params.add("password", password);
		httpClient.post(PATH, params , new TextHttpResponseHandler() {
			
			@Override
			public void onSuccess(int statusCode, Header[] headers,
					String responseString) {
				Toast.makeText(MainActivity.this, responseString, Toast.LENGTH_SHORT).show();
			}
			
			@Override
			public void onFailure(int statusCode, Header[] headers,
					String responseString, Throwable throwable) {
				// TODO Auto-generated method stub
				
			}
		});
	}

	public class StreamUtils {
	
		public static String stream2string(InputStream is) throws IOException {
			
			ByteArrayOutputStream bos = new ByteArrayOutputStream();
			int len=-1;
			byte[] buffer = new byte[1024];
			while((len=is.read(buffer))!=-1){
				bos.write(buffer, 0, len);
			}
			is.close();
			bos.close();
			return bos.toString();
		}
	
	}

文件上传

private TextView tv_file;
	private static String PATH = "http://192.168.37.2:8080/http/fileuploadServlet";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		tv_file = (TextView) findViewById(R.id.tv_file);
	}

	//文件上传，从本地上传到服务器
	public void click(View view) throws FileNotFoundException{
		
		//获取本地图片地址/mnt/sdcard/10.jpg
		String filePath = tv_file.getText().toString().trim();
		
		AsyncHttpClient httpClient = new AsyncHttpClient();
		
		RequestParams params = new RequestParams();
		File file = new File(filePath);
		params.put("file", file);
		
		httpClient.post(PATH, params,new TextHttpResponseHandler() {
			
			@Override
			public void onSuccess(int statusCode, Header[] headers,
					String responseString) {
				Toast.makeText(MainActivity.this, responseString, Toast.LENGTH_SHORT).show();
			}
			
			@Override
			public void onFailure(int statusCode, Header[] headers,
					String responseString, Throwable throwable) {
				
			}
