• Springboot笔记-有header的post请求、get请求

    1、post请求过程中，header中的身份信息怎么加进去并传输？

    首先写一个基础方法 send ，将header信息填写进来

    package com.boc.web;

import java.io.IOException;

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicHeader;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;

import com.alibaba.fastjson.JSONObject;
import com.sun.el.parser.ParseException;

public class PostSend {

	   public static String send(String url, JSONObject jsonObject, String encoding) throws ParseException, IOException {
		      String body = "";
		 
		      //创建httpclient对象
		      CloseableHttpClient client = HttpClients.createDefault();
		      //创建post方式请求对象
		      HttpPost httpPost = new HttpPost(url);
		 
		      //装填参数
		      StringEntity s = new StringEntity(jsonObject.toString(), "utf-8");
		      s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
		      //设置参数到请求对象中
		      httpPost.setEntity(s);
		      System.out.println("请求地址：" + url);
//		        System.out.println("请求参数："+nvps.toString());
		 
		      //设置header信息
		      //指定报文头【Content-type】、【User-Agent】
//		        httpPost.setHeader("Content-type", "application/x-www-form-urlencoded");
		      httpPost.setHeader("Content-type", "application/json");
		      httpPost.setHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");
		      
		      httpPost.addHeader("clientId","****************");
		      httpPost.addHeader("clientSecret","****************");
		      httpPost.addHeader("grantType","***************");
		      //执行请求操作，并拿到结果（同步阻塞）
		      CloseableHttpResponse response = client.execute(httpPost);
		      //获取结果实体
		      HttpEntity entity = response.getEntity();
		      if (entity != null) {
		         //按指定编码转换结果实体为String类型
		         body = EntityUtils.toString(entity, encoding);
		      }
		      EntityUtils.consume(entity);
		      //释放链接
		      response.close();
		      return body;
		 
		   }
}

    然后就可以在create中调用该方法了

    	@ResponseBody
	@GetMapping("/create")
	public String create(@RequestParam("poolname") String poolname, @RequestParam("phonenum") String phonenum) 
			throws ParseException {
		
		//list格式的"phones"字段封装成json数组:enclosure
		String data = null;
		ArrayList<HashMap<String, String>> enclosureList = new ArrayList<HashMap<String, String>>();
		HashMap<String, String> tmpHash = new HashMap<String, String>();
		tmpHash.put("phone", phonenum);
		enclosureList.add(tmpHash);
		JSONArray enclosure = JSONArray.parseArray(JSON.toJSONString(enclosureList));
		
		//创建号码池URL
		String url = "https://*****************************";
		
		//Json对象存储访问参数
		JSONObject jsonParam = new JSONObject();
		jsonParam.put("name", poolname);
		jsonParam.put("callCondition", "voice_upload");
		jsonParam.put("phoneDecryption", "asccode");
		jsonParam.put("phones", enclosure);

		try {		
			//调用post请求方式
			data = PostSend.send(url, jsonParam, "UTF-8");
		} 
		catch (IOException e) {
			e.printStackTrace();
		}

		return data;

	}

    • 33

    接下来详解一下create方法，主要分成三大部分，下面逆序讲解

    （3）服务器方要求：post访问中，body设置json格式。

    		{
		    "name":"Test1",
		    "callCondition":"voice_upload",
		    "phoneDecryption":"asccode",
		    "phones":[
		        {
		            "phone":"188000000"
		        }
		    ]
		}

    • 8
    • 9
    • 10

    在这里插入图片描述

    因此需要将数据都存储成json对象。

    		//Json对象存储访问参数
		JSONObject jsonParam = new JSONObject();
		jsonParam.put("name", poolname);
		jsonParam.put("callCondition", "voice_upload");
		jsonParam.put("phoneDecryption", "asccode");
		jsonParam.put("phones", enclosure);

    • 6

    jsonParam.put 要求输入是String类型的键值对，如“callCondition”, “voice_upload”、“phoneDecryption”, “asccode”。而 poolname 是接收的前端 index.html 传输过来的字符，因此需要在方法中填写参数：

    public String create(@RequestParam("poolname") String poolname, @RequestParam("phonenum") String phonenum) 
			throws ParseException {

    • 2

    同理，phonenum 也是同样利用前端传递获得的，只不过与 poolname 略有不同，见下

    （2）观察发现，前三个参数都是一对一String键值对，而 phonenum 是List的map型，因此需要通过下述方法整合成json数组

    	 "phones":[
			        {
			            "phone":"188000000"
			        }
			    ]

    		//list格式的"phones"字段封装成json数组:enclosure
		String data = null;
		ArrayList<HashMap<String, String>> enclosureList = new ArrayList<HashMap<String, String>>();
		HashMap<String, String> tmpHash = new HashMap<String, String>();
		tmpHash.put("phone", phonenum);
		enclosureList.add(tmpHash);
		JSONArray enclosure = JSONArray.parseArray(JSON.toJSONString(enclosureList));

    （1）然后可调用前面的 send 方法了

    data = PostSend.send(url, jsonParam, "UTF-8");

    参考文章

    2、get请求过程中，header中的身份信息怎么加进去并传输？

    首先写一个基础方法 send ，将header信息填写进来

    package com.boc.web;

import java.util.Arrays;

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;

public class GetSend {
	// ************ GET ***************
	/**
	 * Spring Boot Get请求
	 */
	public static ResponseEntity<String> getsend(String url) {

		RestTemplate restTemplate = new RestTemplate();
		HttpHeaders headers = new HttpHeaders();
		headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
		headers.add("clientId", "*****************");
		headers.add("clientSecret", "**********************");
		headers.add("grantType", "************************");
		HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
		ResponseEntity<String> result = restTemplate.exchange(url, HttpMethod.GET, entity, String.class);

		return result;
	}

}

    • 27
    • 28
    • 29
    • 30
    • 31
    • 32

    然后就可以在 taskprocess 中调用该方法了

    	@ResponseBody
	@RequestMapping("/taskprocess")
	public ResponseEntity<String> taskprocess(@RequestParam("taskid") String taskid) 
			throws ParseException {
		ResponseEntity<String> data = null;
		
		//外呼进度查询URL
		String url = "https://robot.wewecall.com/callout-adapter/adapter/tasks/process/" + taskid;
		
		//调用get请求方式
		data = GetSend.getsend(url);

		return data;
	}

    • 8
    • 9
    • 10
    • 11
    • 12
    • 13
    • 14

    与post相同的原理， taskid 通过前端传入获取。
