java调用http api接口（java创建http接口及调用）

1.修改web.xml文件

2. <servlet>
3. <servlet-name>TestHTTPServer</servlet-name>
4. <servlet-class>com.atoz.http.SmsHTTPServer</servlet-class>
5. </servlet>
6. <servlet-mapping>
7. <servlet-name>TestHTTPServer</servlet-name>
8. <url-pattern>/httpServer</url-pattern>
9. </servlet-mapping>

2.新建SmsHTTPServer.java文件

2. package com.atoz.http;
3. import java.io.IOException;
4. import java.io.PrintWriter;
5. import javax.servlet.ServletException;
6. import javax.servlet.http.HttpServlet;
7. import javax.servlet.http.HttpServletrequest;
8. import javax.servlet.http.HttpServletResponse;
9. import com.atoz.action.order.SendSMSAction;
10. import com.atoz.util.SpringContextUtil;
11. public class SmsHTTPServer extends HttpServlet {
13. private static final long serialVersionUID = 1L;
14. public void doGet(HttpServletRequest request, HttpServletResponse response)
15. throws ServletException, IOException {
16. response.setContentType("text/html;charset=utf-8");
17. request.setCharacterEncoding("utf-8");
18. response.setCharacterEncoding("utf-8");
19. PrintWriter out = response.getWriter();
20. String content = request.getParameter("content");
21. //String content = new String(request.getParameter("content").getBytes("iso-8859-1"), "utf-8");
22. String mobiles = request.getParameter("mobiles");
23. String businesscode = request.getParameter("businesscode");
24. String businesstype = request.getParameter("businesstype");
25. if (content == null || "".equals(content) || content.length() <= 0) {
26. System.out.println("http call failed,参数content不能为空,程序退出");
27. } else if (mobiles == null || "".equals(mobiles)
28. || mobiles.length() <= 0) {
29. System.out.println("http call failed,参数mobiles不能为空,程序退出");
30. } else {
31. /*SendSMSServiceImpl send = new SendSMSServiceImpl();*/
32. SendSMSAction sendSms = (SendSMSAction) SpringContextUtil.getBean("sendSMS");
33. sendSms.sendSms(content, mobiles, businesscode, businesstype);
34. System.out.println("---http call success---");
35. }
36. out.close();
37. }
38. public void doPost(HttpServletRequest request, HttpServletResponse response)
39. throws ServletException, IOException {
40. this.doGet(request, response);
41. }
42. }

3.调用http接口

2. String content = "测试";
3. content = URLEncoder.encode(content, "utf-8");
4. String url = "http://localhost:8180/atoz_2014/httpServer?content=" content "&mobiles=15301895007";
6. URL httpTest;
7. try {
8. httpTest = new URL(url);
9. BufferedReader in;
10. try {
11. in = new BufferedReader(new InputStreamReader(
12. httpTest.openStream()));
13. String inputLine = null;
14. String resultMsg = null;
15. //得到返回信息的xml字符串
16. while ((inputLine = in.readLine()) != null)
17. if(resultMsg != null){
18. resultMsg = inputLine;
19. }else {
20. resultMsg = inputLine;
21. }
22. in.close();
23. } catch (MalformedURLException e) {
24. e.printStackTrace();
25. }
26. } catch (IOException e) {
27. // TODO Auto-generated catch block
28. e.printStackTrace();
29. }
