Android Http Get/Post提交请求

 

首先添加访问Internet权限：

<uses-permission android:name="android.permission.INTERNET"/>

 示例代码：

 

public static boolean sendGetRequest(String path, 
		Map<String, String> params, String enc) throws Exception{

	StringBuilder sb = new StringBuilder(path);
	sb.append('?');
	//?method=save&title=12345678&timelength=26&
	//迭代Map拼接请求参数
	for(Map.Entry<String, String> entry : params.entrySet()){
		sb.append(entry.getKey()).append('=')
			.append(URLEncoder.encode(entry.getValue(), enc)).append('&');
	}
	sb.deleteCharAt(sb.length()-1);//删除最后一个"&"
	
	URL url = new URL(sb.toString());
	HttpURLConnection conn = (HttpURLConnection)url.openConnection();
	conn.setRequestMethod("GET");
	conn.setConnectTimeout(5 * 1000);
	if(conn.getResponseCode()==200){
		return true;
	}
	return false;
}

public static boolean sendPostRequest(String path, 
		Map<String, String> params, String enc) throws Exception{
	
	// title=dsfdsf&timelength=23&method=save
	StringBuilder sb = new StringBuilder();
	if(params!=null && !params.isEmpty()){
		//迭代Map拼接请求参数
		for(Map.Entry<String, String> entry : params.entrySet()){
			sb.append(entry.getKey()).append('=')
				.append(URLEncoder.encode(entry.getValue(), enc)).append('&');
		}
		sb.deleteCharAt(sb.length()-1);//删除最后一个"&"
	}
	byte[] entitydata = sb.toString().getBytes();//得到实体的二进制数据
	URL url = new URL(path);
	HttpURLConnection conn = (HttpURLConnection)url.openConnection();
	conn.setRequestMethod("POST");
	conn.setConnectTimeout(5 * 1000);
	//如果通过post提交数据，必须设置允许对外输出数据
	conn.setDoOutput(true);
	//此两参数必须设置
	//Content-Type: application/x-www-form-urlencoded
	//Content-Length: 38
	conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
	conn.setRequestProperty("Content-Length", String.valueOf(entitydata.length));
	OutputStream outStream = conn.getOutputStream();
	outStream.write(entitydata);
	outStream.flush();
	outStream.close();
	if(conn.getResponseCode()==200){
		return true;
	}
	return false;
}

//HttpClient组件  SSL HTTPS Cookie
public static boolean sendRequestFromHttpClient(String path, 
		Map<String, String> params, String enc) throws Exception{

	List<NameValuePair> paramPairs = new ArrayList<NameValuePair>();
	if(params!=null && !params.isEmpty()){
		for(Map.Entry<String, String> entry : params.entrySet()){
			paramPairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
		}
	}
	//得到经过编码过后的实体数据
	UrlEncodedFormEntity entitydata = new UrlEncodedFormEntity(paramPairs, enc);
	HttpPost post = new HttpPost(path); //form
	post.setEntity(entitydata);
	DefaultHttpClient client = new DefaultHttpClient(); //浏览器
	HttpResponse response = client.execute(post);//执行请求
	if(response.getStatusLine().getStatusCode()==200){
		return true;
	}
	return false;
}

 

 

单元测试：

 

public void testSendGetRequest() throws Throwable{
	//?method=save&title=12345678&timelength=26
	Map<String, String> params = new HashMap<String, String>();
	params.put("method", "save");
	params.put("title", "yaku");
	params.put("timelength", "80");
	
	HttpRequest.sendGetRequest("http://192.168.1.2:8080/webserver/server/manage.do", params, "UTF-8");
}

public void testSendPostRequest() throws Throwable{
	Map<String, String> params = new HashMap<String, String>();
	params.put("method", "save");
	params.put("title", "胡汉三");
	params.put("timelength", "80");
	
	HttpRequest.sendPostRequest("http://192.168.1.2:8080/webserver/server/manage.do", params, "UTF-8");
}

public void testSendRequestFromHttpClient() throws Throwable{
	Map<String, String> params = new HashMap<String, String>();
	params.put("method", "save");
	params.put("title", "开天");
	params.put("timelength", "80");
	
	HttpRequest.sendRequestFromHttpClient("http://192.168.1.2:8080/webserver/server/manage.do", params, "UTF-8");
}
