方法一：
（原始辦法）
/*
?* @remark: 獲取用戶資料
?* @param: url發送數據的URL
?* @param: param獲取用戶資料的參數
?* @return: 獲取用戶資料狀態信息
?*/
?String GetUser(String url, String param)
?{
??URL httpurl = null;
??HttpURLConnection httpConn = null;
??String line = "";
?? try
?? {
???? httpurl = new URL(url);
???? httpConn = (HttpURLConnection)httpurl.openConnection();??
???? httpConn.setRequestMethod("POST");??? //默認是post
???? httpConn.setDoOutput(true);
???? httpConn.setDoInput(true);?
???? PrintWriter outs = new PrintWriter(httpConn.getOutputStream());
???? outs.print(param);
???? outs.flush();
???? outs.close();???
???? BufferedReader? in = new BufferedReader(new InputStreamReader(httpConn.getInputStream()));??
???? while ((line = in.readLine()) != null)
??? {
?? ? ? if (line.indexOf("#") == -1)
??? ??? continue;
??? ? return line;
??? }
??? in.close();
?
?? }catch(Exception e)
?? {
?? ??return line;
?? }
?? finally
?? {
???? if(httpConn!=null)
?????? httpConn.disconnect();
?? }
??return line;
?}
該方法寫的很簡單，不夠完善。
方法二：
<%@ page language="java"? pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>?
? <body>
??? <%
??????? String name1=request.getParameter("name1");
??????? if(null!=name1){
??????????? out.print(name1);out.print("<br>");
??????? }
??????? String name2=request.getParameter("name2");
??????? if(null!=name1){
??????????? out.print(name2);out.print("<br>");
??????? }
??? %>
? </body>
</html>
接下來就就是我們的程序部分了:
import java.io.IOException;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;
public class Test {
??? /**
???? * @param args
???? */
??? public static void main(String[] args) {
??????? HttpClient client = new HttpClient();
??????? HttpMethod httpPost =getPostMethod();
??????? //HttpMethod httpPost =getGetMethod();
??????? client.getHostConfiguration().setHost("localhost", 8080, "http");
??????? try {
??????????? int status = client.executeMethod(httpPost);
??????????? if(status==200)
??????????? {
??????????????? System.out.println(httpPost.getResponseBodyAsString());
??????????? }
??????????? else
??????????? {
??????????????? System.out.println("頁面請求返回值為："+status);
??????????? }
??????? } catch (HttpException e) {
??????????? e.printStackTrace(System.err);
??????? } catch (IOException e) {
??????????? e.printStackTrace(System.err);
??????? }finally{
??????????? httpPost.releaseConnection();
??????? }
??? }
??? /**
???? * 使用POST方式提交數據
???? * @return
???? */
??? private static HttpMethod getPostMethod(){
??????? PostMethod post = new PostMethod("/PostTest/index.jsp");
??????? NameValuePair simcard = new NameValuePair("name1","1330227");
??????? NameValuePair simcard2 = new NameValuePair("name2","kjasdfklalsf");
??????? post.setRequestBody(new NameValuePair[] { simcard,simcard2});
??????? return post;
??? }
??? /**
???? * 使用GET方式提交數據
???? * @return
???? */
??? private static HttpMethod getGetMethod(){
??????? return new GetMethod("/PostTest/index.jsp?name1=1330227&name2=asdfsdf");
??? }
}
注意:大家要把commons-codec-1.3.jar,commons-httpclient-3.0.jar,commons-logging.jar這三個JAR包加到我們程序的classpath中,才能使用跑起來.
