java如何调用对方http接口

你是指发送http请求吗，可以使用Apache 的 HttpClient

        //构建HttpClient实例

        CloseableHttpClient httpclient = HttpClients.createDefault();        //设置请求超时时间

        RequestConfig requestConfig = RequestConfig.custom()                .setSocketTimeout(60000)                .setConnectTimeout(60000)                .setConnectionRequestTimeout(60000)                .build();        //指定POST请求

        HttpPost httppost = new HttpPost(url);

        httppost.setConfig(requestConfig);        //包装请求体

        ListNameValuePair params = new ArrayListNameValuePair();        params.addAll(content);

        HttpEntity request = new UrlEncodedFormEntity(params, "UTF-8");        //发送请求

        httppost.setEntity(request);

        CloseableHttpResponse httpResponse = httpclient.execute(httppost);        //读取响应

        HttpEntity entity = httpResponse.getEntity();        String result = null;        if (entity != null) {

            result = EntityUtils.toString(entity, "UTF-8");

        }

java如何创建一个简单的http接口？

1.修改web.xml文件

!-- 模拟HTTP的调用，写的一个http接口 -- servlet servlet-nameTestHTTPServer/servlet-name servlet-classcom.atoz.http.SmsHTTPServer/servlet-class /servlet servlet-mapping servlet-nameTestHTTPServer/servlet-name url-pattern/httpServer/url-pattern /servlet-mapping

2.新建SmsHTTPServer.java文件

package com.atoz.http;

import java.io.IOException; import java.io.PrintWriter;

import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

import com.atoz.action.order.SendSMSAction; import com.atoz.util.SpringContextUtil;

public class SmsHTTPServer extends HttpServlet { private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); PrintWriter out = response.getWriter(); String content = request.getParameter("content"); //String content = new String(request.getParameter("content").getBytes("iso-8859-1"), "utf-8"); String mobiles = request.getParameter("mobiles"); String businesscode = request.getParameter("businesscode"); String businesstype = request.getParameter("businesstype"); if (content == null || "".equals(content) || content.length() = 0) { System.out.println("http call failed,参数content不能为空,程序退出"); } else if (mobiles == null || "".equals(mobiles) || mobiles.length() = 0) { System.out.println("http call failed,参数mobiles不能为空,程序退出"); } else { /*SendSMSServiceImpl send = new SendSMSServiceImpl();*/ SendSMSAction sendSms = (SendSMSAction) SpringContextUtil.getBean("sendSMS"); sendSms.sendSms(content, mobiles, businesscode, businesstype); System.out.println("---http call success---"); } out.close(); }

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doGet(request, response); } }

3.调用http接口

String content = "测试"; content = URLEncoder.encode(content, "utf-8"); String url = "" + content + "mobiles=15301895007"; URL httpTest; try { httpTest = new URL(url); BufferedReader in; try { in = new BufferedReader(new InputStreamReader( httpTest.openStream())); String inputLine = null; String resultMsg = null; //得到返回信息的xml字符串 while ((inputLine = in.readLine()) != null) if(resultMsg != null){ resultMsg += inputLine; }else { resultMsg = inputLine; } in.close(); } catch (MalformedURLException e) { e.printStackTrace(); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }

打字不易，望采纳，谢谢

如何用Java通过POST方法向HTTP接口传递数据？

这是corejava2的例子\x0d\x0aURLConnectionconnection=url.openConnection();//url为http服务器地址\x0d\x0aconnection.setDoOutput(true);\x0d\x0aPrintWriterout\x0d\x0a=newPrintWriter(connection.getOutputStream());//获得输出流\x0d\x0a//向服务器传递参数\x0d\x0aEnumerationenum=nameValuePairs.keys();\x0d\x0awhile(enum.hasMoreElements())\x0d\x0a{Stringname=(String)enum.nextElement();\x0d\x0aStringvalue=nameValuePairs.getProperty(name);\x0d\x0acharch;\x0d\x0aif(enum.hasMoreElements())ch='';elsech='\n';\x0d\x0aout.print(name+"="\x0d\x0a+URLEncoder.encode(value)+ch);\x0d\x0aSystem.out.println(name+value);\x0d\x0a}\x0d\x0a\x0d\x0aout.close();\x0d\x0a//获取输入流\x0d\x0aBufferedReaderin;\x0d\x0atry\x0d\x0a{in=newBufferedReader(new\x0d\x0aInputStreamReader(connection.getInputStream()));\x0d\x0a}\x0d\x0acatch(FileNotFoundExceptionexception)\x0d\x0a{InputStreamerr\x0d\x0a=((HttpURLConnection)connection).getErrorStream();\x0d\x0aif(err==null)throwexception;\x0d\x0ain=newBufferedReader(newInputStreamReader(err));\x0d\x0a}\x0d\x0aStringBufferresponse=newStringBuffer();\x0d\x0aStringline;\x0d\x0a//读取数据\x0d\x0awhile((line=in.readLine())!=null)\x0d\x0aresponse.append(line+"\n");\x0d\x0a\x0d\x0ain.close();\x0d\x0areturnresponse.toString();\x0d\x0a}\x0d\x0a}
