一.
1、写一个HttpRequestUtils工具类,包括post请求和get请求
package com.brainlong.framework.util.httpclient; import net.sf.json.JSONObject; import org.apache.commons.httpclient.HttpStatus; import org.apache.http.HttpResponse; import org.apache.http.client.methods.HttpGet; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.util.EntityUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import java.io.IOException;import java.net.URLDecoder; public class HttpRequestUtils { private static Logger logger = LoggerFactory.getLogger(HttpRequestUtils.class); //日志记录 /** * httpPost * @param url 路径 * @param jsonParam 参数 * @return */ public static JSONObject httpPost(String url,JSONObject jsonParam){ return httpPost(url,jsonParam,false); } /** * post请求 * @param url url地址 * @param jsonParam 参数 * @param noNeedResponse 不需要返回结果 * @return */ public static JSONObject httpPost(String url,JSONObject jsonParam,boolean noNeedResponse){ //post请求返回结果 DefaultHttpClient httpClient = new DefaultHttpClient(); JSONObject jsonResult = null; HttpPost method = new HttpPost(url); try { if (null != jsonParam) { //解决中文乱码问题 StringEntity entity = new StringEntity(jsonParam.toString(),"utf-8"); entity.setContentEncoding("UTF-8"); entity.setContentType("application/json"); method.setEntity(entity); } HttpResponse result = httpClient.execute(method); url = URLDecoder.decode(url,"UTF-8"); /**请求发送成功,并得到响应**/ if (result.getStatusLine().getStatusCode() == 200) { String str = ""; try { /**读取服务器返回过来的json字符串数据**/ str = EntityUtils.toString(result.getEntity()); if (noNeedResponse) { return null; } /**把json字符串转换成json对象**/ jsonResult = JSONObject.fromObject(str); } catch (Exception e) { logger.error("post请求提交失败:" + url,e); } } } catch (IOException e) { logger.error("post请求提交失败:" + url,e); } return jsonResult; } /** * 发送get请求 * @param url 路径 * @return */ public static JSONObject httpGet(String url){ //get请求返回结果 JSONObject jsonResult = null; try { DefaultHttpClient client = new DefaultHttpClient(); //发送get请求 HttpGet request = new HttpGet(url); HttpResponse response = client.execute(request); /**请求发送成功,并得到响应**/ if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { /**读取服务器返回过来的json字符串数据**/ String strResult = EntityUtils.toString(response.getEntity()); /**把json字符串转换成json对象**/ jsonResult = JSONObject.fromObject(strResult); url = URLDecoder.decode(url,"UTF-8"); } else { logger.error("get请求提交失败:" + url); } } catch (IOException e) { logger.error("get请求提交失败:" + url,e); } return jsonResult; }}
2、写业务代码发送Http请求
3、MVC配置文件设置Controller扫描目录
<!-- 自动扫描且只扫描@Controller --> <context:component-scan base-package="com.wiselong.multichannel" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan>
4、接收Http请求
接收post请求
@Controller @RequestMapping(value = "/api/platform/exceptioncenter/exceptioninfo") public class ExceptionInfoController { //注入 @Autowired private ExceptionInfoBiz exceptionInfoBiz; /** * 创建异常信息请求 * @param requestBody 请求消息内容 * @param request 请求消息头 * @return jsonObject */ @RequestMapping( value="/create",method = RequestMethod.POST ) public ModelAndView createExceptionInfo(@RequestBody String requestBody, HttpServletRequest request) { JSONObject jsonObject = JSONObject.fromObject(requestBody); ComExceptionInfo comExceptionInfo = new ComExceptionInfo(); comExceptionInfo.setProjectName(jsonObject.getString("projectName")); comExceptionInfo.setTagName(jsonObject.getString("tagName")); exceptionInfoBiz.insert(comExceptionInfo); //返回请求结果 JSONObject result= new JSONObject(); result.put("success", "true"); return new ModelAndView("", ResponseUtilsHelper.jsonSuccess(result.toString())); } }
接收get请求
@Controller @RequestMapping(value="/api/platform/messagecenter/messages/sms") public class SmsController { @Autowired SmsSendBiz smsSendBiz; /** * 接收手机号码和内容往短信发送表插入一条记录 * @param requestbody 请求消息内容 * @param request 请求消息头 * @return jsonObject */ @RequestMapping( value="/send",method= RequestMethod.GET ) public ModelAndView sendSms(@RequestBody String requestbody, HttpServletRequest request) { //获取请求URL及url后面传输的参数 String url = request.getRequestURL() + "?" + request.getQueryString(); url = BuildRequestUrl.decodeUrl(url); String telePhone = RequestUtils.getStringValue(request, "telePhone"); String content = RequestUtils.getStringValue(request, "content"); smsSendBiz.insertTtMsQuequ(telePhone,content); return new ModelAndView("", ResponseUtilsHelper.jsonResult("", true)); } }
二.
get
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpMethod; import org.apache.commons.httpclient.methods.GetMethod; public class H_client_get { public static void main(String[] args) throws IOException { // new类对象 HttpClient client = new HttpClient(); // 使用 GET 方法 与URL服务器进行交互 // HttpMethod method = new GetMethod("http://192.168.111.128/bak/regist.php?email=admin@admin.com&password=1234567&re_password=1234567&username=admin&nickname=管理员"); HttpMethod method = new GetMethod("http://192.168.111.128/bak/login.php?username="); // 使用 GET 方法 ,实行与url服务器连接 client.executeMethod(method); // 数据流输出 // method.getResponseBodyAsStream 创建字节流对象为inputStream InputStream inputStream = method.getResponseBodyAsStream(); // InputStreamReader(inputStream)字节流转换成字符流 BufferedReader封装成带有缓冲的字符流对象了 BufferedReader br = new BufferedReader(new InputStreamReader(inputStream,"UTF-8")); // StringBuffer是字符串变量,它的对象是可以扩充和修改的 创建一个空的StringBuffer类的对象 StringBuffer stringBuffer = new StringBuffer(); // 定义字符串常量 String str= ""; // br字符流赋值给str字符串常量 str不等于空 按行输出 while((str = br.readLine()) != null){ // StringBuffer 是字符串变量,它的对象是可以扩充和修改的 将str数据赋予 stringBuffer stringBuffer .append(str ); } // 按照字符串循环输出stringBuffer System.out.println(stringBuffer.toString()); // 关闭method 的 httpclient连接 method.releaseConnection(); } }
