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getMethodint 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; 13. String month = result; 14. String day = result; 15. String hour = result; 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) { 20. if(filter.isExistsDirectory(url + "/" + year, month + "")) { 21. if(filter.isExistsDirectory(url + "/" + year + "/" + month, day + "")) { 22. if(!filter.isExistsDirectory(url + "/" + year + "/" + month + "/" + hour, hour + "")) { 23. new File(url + "/" + year + "/" + month + "/" + day + "/" + hour).mkdir(); 24. } 25. } else { 26. new File(url + "/" + year + "/" + month + "/" + day).mkdir(); 27. } 28. } else { 29. new File(url + "/" + year + "/" + month).mkdir(); 30. } 31. } else { 32. new File(url + "/" + year).mkdir(); 33. new File(url + "/" + year + "/" + month).mkdir(); 34. new File(url + "/" + year + "/" + month + "/" + day).mkdir(); 35. new File(url + "/" + year + "/" + month + "/" + day + "/" + hour).mkdir(); 36. } 37. return url + "/" + year + "/" + month + "/" + day + "/" + hour; 38. } 39. 40. 41. class MyFileFilter implements java.io.FileFilter { 42. 43. private boolean isDirectory; 44. 45. public MyFileFilter(boolean isDir) { 46. this.isDirectory = isDir; 47. } 48. 49. @Override 50. public boolean accept(File f) { 51. if (f.isDirectory() == isDirectory) { 52. return true; 53. } else 54. return false; 55. } 56. 57. public boolean isExistsDirectory(String path, String dir) { 58. File file = new File(path); 59. File[] childFiles = file.listFiles(this); 60. for (File cFile : childFiles) { 61. if(cFile.equals(dir)) { 62. return true; 63. } 64. } 65. return false; 66. } 67. }
