RestTemplate通过HTTPS协议访问接口

RestTemplate 默认不支持https协议，需要支持有两种方式，第一种是忽略认证，第二种是导入证书（比第一种安全）

在这里只实现第一种方式，实现代码如下

package com.muge.other.controller;

import com.alibaba.fastjson.JSONObject;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.apache.http.ssl.TrustStrategy;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
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;
import org.springframework.web.client.RestTemplate;

import javax.net.ssl.SSLContext;

@Controller
@RequestMapping("/rest")
public class RestTemplateTest {
          
   
    
    @RequestMapping(value = "/test.info",method = RequestMethod.GET)
    @ResponseBody
    public void test(){
          
   
        RestTemplate restTemplateHttps= restTemplateHttps();
        HttpHeaders headers = new HttpHeaders();
        headers.add("Content-Type", "application/json;charset=UTF-8");

        /*MultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
        map.add("userName", "admin");
        map.add("password", "123456");
        HttpEntity<MultiValueMap<String, Object>> httpEntity = new HttpEntity<>(map,headers);
        String resp =restTemplateHttps.postForObject("https://192.168.2.102:18531/loginInfo/login/v1.0", httpEntity, String.class);
        System.out.println(resp);*/
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("userName","admin");
        jsonObject.put("password","123456");

        JSONObject jsonObject1 = restTemplateHttps.postForObject("https://192.168.2.102:18531/loginInfo/login/v1.0",new HttpEntity<>(jsonObject,headers),JSONObject.class);
        System.out.println(jsonObject1);
    }

    public RestTemplate restTemplateHttps()  {
          
   
        RestTemplate restTemplate = null;
        try {
          
   
            TrustStrategy acceptingTrustStrategy = (chain, authType) -> true;
            SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);

            HttpClientBuilder clientBuilder = HttpClients.custom();

            CloseableHttpClient httpClient = clientBuilder.setSSLSocketFactory(sslsf).build();

            HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
            requestFactory.setHttpClient(httpClient);

            restTemplate = new RestTemplate(requestFactory);
        } catch (Exception e) {
          
   
            e.printStackTrace();
        }
        return restTemplate;
    }
}
