1,需要同時(shí)使用commons-codec-1.3.jar
2,處理header
a.jsp
<%@ page language="java" pageEncoding="UTF-8"%>
<%
??? response.addHeader("location","beijing");
%>
3,
??????????? HttpClient client = new HttpClient();
??????????? HeadMethod headMethod = new HeadMethod(
??????????????????? "http://localhost:8080/Test/jsp/a.jsp");
??????????? client.executeMethod(headMethod);
??????????? Header[] headers = headMethod.getResponseHeaders();
??????????? System.out.println(headers.length);
??????????? for (int i = 0; i < headers.length; i++) {
??????????????? out.println(headers[i] + " <br>");
??????????? }
??????????? headMethod.releaseConnection();
4，
httpclient默認(rèn)使用ISO-8859-1讀取http響應(yīng)的內(nèi)容，如果內(nèi)容中包含漢字的話就得動用丑陋的new String(str.getBytes("ISO-8859-1"),"GBK");語句了。
解決辦法
HttpClient client = new HttpClient();
??? client.getParams().setParameter(
????? HttpMethodParams.HTTP_CONTENT_CHARSET, "GBK");
5，設(shè)置 Http 連接超時(shí)為2秒
httpclient.getHttpConnectionManager().getParams().setConnectionTimeout(2000);
