htmlclient

1.一个根据动态页路径和编码格式获得html格式文本的方法源代码:
Java代码

   1. // 返回html代码  
   2.     public final static String getHtmlCode(String httpUrl, String ecode) {  
   3.         // 构造HttpClient的实例  
   4.         HttpClient httpClient = new HttpClient();  
   5.         // 创建GET方法的实例  
   6.         GetMethod getMethod = new GetMethod(httpUrl);  
   7.         // 使用系统提供的默认的恢复策略  
   8.         getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,  
   9.                 new DefaultHttpMethodRetryHandler());  
  10.         try {  
  11.             // 执行getMethod  
  12.             int statusCode = httpClient.executeMethod(getMethod);  
  13.             if (statusCode != HttpStatus.SC_OK) {  
  14.                 System.err.println("Method failed: "  
  15.                         + getMethod.getStatusLine());  
  16.             }  
  17.             // 读取内容  
  18.             byte[] responseBody = getMethod.getResponseBody();  
  19.             // 处理内容  
  20.             return new String(responseBody, ecode);  
  21.         } catch (HttpException e) {  
  22.             // 发生致命的异常，可能是协议不对或者返回的内容有问题  
  23.             System.out.println("Please check your provided http address!");  
  24.             e.printStackTrace();  
  25.         } catch (IOException e) {  
  26.             // 发生网络异常  
  27.             e.printStackTrace();  
  28.         } finally {  
  29.             // 释放连接  
  30.             getMethod.releaseConnection();  
  31.         }  
  32.         return null;  
  33.     }  

// 返回html代码
	public final static String getHtmlCode(String httpUrl, String ecode) {
		// 构造HttpClient的实例
		HttpClient httpClient = new HttpClient();
		// 创建GET方法的实例
		GetMethod getMethod = new GetMethod(httpUrl);
		// 使用系统提供的默认的恢复策略
		getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
				new DefaultHttpMethodRetryHandler());
		try {
			// 执行getMethod
			int statusCode = httpClient.executeMethod(getMethod);
			if (statusCode != HttpStatus.SC_OK) {
				System.err.println("Method failed: "
						+ getMethod.getStatusLine());
			}
			// 读取内容
			byte[] responseBody = getMethod.getResponseBody();
			// 处理内容
			return new String(responseBody, ecode);
		} catch (HttpException e) {
			// 发生致命的异常，可能是协议不对或者返回的内容有问题
			System.out.println("Please check your provided http address!");
			e.printStackTrace();
		} catch (IOException e) {
			// 发生网络异常
			e.printStackTrace();
		} finally {
			// 释放连接
			getMethod.releaseConnection();
		}
		return null;
	}

 2.将html文本写入一个文件中的方法(para1:保存文件名 para2:html文本内容)
Java代码

   1. public final static void saveHtmlCode(String filePath, String htmlCode) {  
   2.         FileOutputStream fOut = null;  
   3.         OutputStreamWriter out = null;  
   4.         try {  
   5.             fOut = new FileOutputStream(filePath);  
   6.             out = new OutputStreamWriter(fOut, "UTF-8");  
   7.             out.write(htmlCode);  
   8.         } catch (Exception e) {  
   9.             e.printStackTrace();  
  10.         } finally {  
  11.             try {  
  12.                 out.flush();  
  13.             } catch (IOException e) {  
  14.                 e.printStackTrace();  
  15.             }  
  16.             try {  
  17.                 fOut.flush();  
  18.             } catch (IOException e) {  
  19.                 e.printStackTrace();  
  20.             }  
  21.             try {  
  22.                 out.close();  
  23.             } catch (IOException e) {  
  24.                 e.printStackTrace();  
  25.             }  
  26.             try {  
  27.                 fOut.close();  
  28.             } catch (IOException e) {  
  29.                 e.printStackTrace();  
  30.             }  
  31.         }  
  32.     }  

public final static void saveHtmlCode(String filePath, String htmlCode) {
		FileOutputStream fOut = null;
		OutputStreamWriter out = null;
		try {
			fOut = new FileOutputStream(filePath);
			out = new OutputStreamWriter(fOut, "UTF-8");
			out.write(htmlCode);
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			try {
				out.flush();
			} catch (IOException e) {
				e.printStackTrace();
			}
			try {
				fOut.flush();
			} catch (IOException e) {
				e.printStackTrace();
			}
			try {
				out.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
			try {
				fOut.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

 3.下面是一段伪代码.根据当前时间现在c盘建立要保存文件的文件夹,然后保存文件
Java代码

   1. public static void main(String[] args) {  
   2.         String msgSaveFile = countHtmlFilePath("c://", new Date()) + "/test.html";  
   3.         String messageHtmlCode = getHtmlCode("test.jsp", "UTF-8");  
   4.         saveHtmlCode(msgSaveFile, messageHtmlCode);  
   5.     }  
   6.       
   7.     // 获得存储文件的目录  
   8.     public final static String countHtmlFilePath(String url, Date date) {  
   9.         SimpleDateFormat sim = new SimpleDateFormat("yyyy-MM-dd-hh");  
  10.         String time = sim.format(date);  
  11.         String[] result = time.split("-");  
  12.         String year = result[0];  
  13.         String month = result[1];  
  14.         String day = result[2];  
  15.         String hour = result[3];   
  16.         // 首先判断是否有年文件夹  
  17.         MyFileFilter filter = new TestClass().new MyFileFilter(true);  
  18.         boolean isExists = filter.isExistsDirectory(url, year + "");  
  19.         if (isExists) {

  22.                     if(!filter.isExistsDirectory(url + "/" + year + "/" + month + "/" + hour, hour + "")) {  
  23.                         new File(url + "/" + year + "/" + month + "/" + day + "/" + hour).mkdir();
