案例描述在平台A上利用接口模拟调运平台B中功能数据
实现思路操作步骤1. 确定平台B的url //定义api,一般情况下这个api的url是第三方提供
- String id = "5qZUoTMjp3LsbO8E4y2";
- String apiurl = "http://example.jepaas.com/je/getInfoById"+"?pkValue="+id+"&authorization=6Dy0QDIS7IRuVXzqmYh&tableCode=JE_DEMO_XMINFO";
复制代码2. 在平台A写接口,利用HttpClientUtil工具类的doPost()方法进行解析并获取数据 3. 在平台A上写个测试按钮,调运接口进行测试 相关代码1 、HttpClientUtil代码 - package com.project.demo.controller;
- import java.io.IOException;
- import java.net.URI;
- import java.util.ArrayList;
- import java.util.List;
- import java.util.Map;
- import org.apache.http.NameValuePair;
- import org.apache.http.client.entity.UrlEncodedFormEntity;
- import org.apache.http.client.methods.CloseableHttpResponse;

- import org.apache.http.util.EntityUtils;
- public class HttpClientUtilTest {
- /**
- * 带参数的get请求
- * @param url
- * @param param
- * @return String
- */
- public static String doGet(String url, Map<String, String> param) {
- // 创建Httpclient对象
- CloseableHttpClient httpclient = HttpClients.createDefault();
- String resultString = "";
- CloseableHttpResponse response = null;
- try {
- // 创建uri
- URIBuilder builder = new URIBuilder(url);
- if (param != null) {
- for (String key : param.keySet()) {
- builder.addParameter(key, param.get(key));
- }
- }
- URI uri = builder.build();
- // 创建http GET请求
- HttpGet httpGet = new HttpGet(uri);
- // 执行请求
- response = httpclient.execute(httpGet);
- // 判断返回状态是否为200
- if (response.getStatusLine().getStatusCode() == 200) {
- resultString = EntityUtils.toString(response.getEntity(), "UTF-8");
- }
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- try {
- if (response != null) {
- response.close();
- }
- httpclient.close();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- return resultString;
- }
- /**
- * 不带参数的get请求
- * @param url
- * @return String
- */
- public static String doGet(String url) {
- return doGet(url, null);
- }
- /**
- * 带参数的post请求
- * @param url
- * @param param
- * @return String
- */
- public static String doPost(String url, Map<String, String> param) {
- // 创建Httpclient对象
- CloseableHttpClient httpClient = HttpClients.createDefault();
- CloseableHttpResponse response = null;
- String resultString = "";
- try {
- // 创建Http Post请求
- HttpPost httpPost = new HttpPost(url);
- // 创建参数列表
- if (param != null) {
- List<NameValuePair> paramList = new ArrayList<>();
- for (String key : param.keySet()) {
- paramList.add(new BasicNameValuePair(key, param.get(key)));
- }
- // 模拟表单
- UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramList);
- httpPost.setEntity(entity);
- }
- // 执行http请求
- response = httpClient.execute(httpPost);
- resultString = EntityUtils.toString(response.getEntity(), "utf-8");
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- try {
- response.close();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- return resultString;
- }
- /**
- * 不带参数的post请求
- * @param url
- * @return String
- */
- public static String doPost(String url) {
- return doPost(url, null);
- }
- /**
- * 传送json类型的post请求
- * @param url
- * @param json
- * @return String
- */
- public static String doPostJson(String url, String json) {
- // 创建Httpclient对象
- CloseableHttpClient httpClient = HttpClients.createDefault();
- CloseableHttpResponse response = null;
- String resultString = "";
- try {
- // 创建Http Post请求
- HttpPost httpPost = new HttpPost(url);
- // 创建请求内容
- StringEntity entity = new StringEntity(json, ContentType.APPLICATION_JSON);
- httpPost.setEntity(entity);
- // 执行http请求
- response = httpClient.execute(httpPost);
- resultString = EntityUtils.toString(response.getEntity(), "utf-8");
- } catch (Exception e) {
- e.printStackTrace();
- } finally {
- try {
- response.close();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- return resultString;
- }
- }
复制代码 2、接口代码 - package com.project.demo.controller;
- import com.je.core.base.MethodArgument;
- import com.je.core.result.BaseRespResult;
- import org.springframework.stereotype.Controller;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RequestMethod;
- import org.springframework.web.bind.annotation.ResponseBody;
- @Controller
- @RequestMapping(value = "/je/demo/test")
- public class TestDemoController {
- @RequestMapping(value = "/testUrl", method = RequestMethod.POST, produces = "application/json; charset=utf-8")
- @ResponseBody
- public BaseRespResult testUrl(MethodArgument param){
- //定义api,一般情况下这个api的url是第三方提供
- String id = "5qZUoTMjp3LsbO8E4y2";
- String apiurl = "http://example.jepaas.com/je/getInfoById"+"?pkValue="+id+"&authorization=6Dy0QDIS7IRuVXzqmYh&tableCode=JE_DEMO_XMINFO";
- String result="";
- try {
- result = HttpClientUtilTest.doPost(apiurl);
- } catch (Exception e) {
- e.printStackTrace();
- }
- return BaseRespResult.successResult(result);
- }
- }
复制代码
平台调试1、在某个功能上写个按钮,进行Ajax调运测试 2、调运代码 - function(btn,event,eOpts){
- var obj = JE.ajax({
- url:'/je/demo/test/testUrl',
- text:false,//返回字符串,如果不配置,返回对象
- params:{}
- });
- if(obj.success){
- console.log(obj);
- JE.alert(obj.obj);
- }else{
- JE.alert('失败,请联系管理员');
- }
- }
复制代码
3、后台断点调试
