背景

使用HttpClients请求外部接口

  @Test
  public void test(){

    try{

      // 使用httpClient请求

      // 请求路径
      String url = "localhost:8080/user/info";

      // 请求头
      Map headerMap = new HashMap();
      headerMap.put("Content-Type", "application/json;chartset=UTF-8");

      // 请求体
      Map body = new HashMap();
      body.put("phone",phone);
      String requstString = JSONObject.toJSONString(body);

      HttpConfig httpConfig = HttpConfigUtil.getHttpConfigForJson(
              headerMap, requstString,
              url,
              700, "UTF-8");
      String result = com.aspire.mall.common.httpclient.HttpClientUtil.post(httpConfig);

      System.out.println("查询用户信息接口返回result:"+result);
      JSONObject jsonObject = JSON.parseObject(result);
      JSONArray subPhoneInfoArray = jsonObject.getJSONObject("Body").getJSONArray("subphonelist");
      for(int i = 0 ;i<subPhoneInfoArray.size();i++){
        JSONObject subPhoneInfo = subPhoneInfoArray.getJSONObject(i);
        subPhones.add(subPhoneInfo.getString("subphone"));
      }

      System.out.println("查询用户信息接口返回subPhones:"+ String.join(",",subPhones));

    }catch (Exception e){
      e.printStackTrace();
    }

  }

但是报缺少安全证书：unable to find valid certification path to requested target

用以下办法能够暂时解决：请求HTTPS接口提示缺少安全证书

但是切换环境证书需要重新生成，不是办法。

使用RestTemplate请求

  @Test
  public void test(){

    try{

      String url = "localhost:8080/user/info";

      // 请求体
      Map body = new HashMap();
      body.put("phone",phone);
      String requstString = JSONObject.toJSONString(body);

      // 请求头
      HttpHeaders headers = new HttpHeaders();
      headers.add("content-type", "application/json;chartset=UTF-8");

      // 请求
      HttpEntity<String> requst = new HttpEntity<>(requstString, headers);


      // 使用RestTemplate请求

      RestTemplate restTemplateHttps = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory());
      ResponseEntity<JSONObject> responseBody = restTemplateHttps.postForEntity(url, requst, JSONObject.class);

      JSONObject httpBody = responseBody.getBody();
      System.out.println("接口返回参数:"+httpBody);

      List<String> subPhones = new ArrayList<>();
      JSONArray subPhoneInfoArray = httpBody.getJSONObject("Body").getJSONArray("subphonelist");
      for(int i = 0 ;i<subPhoneInfoArray.size();i++){
        JSONObject subPhoneInfo = subPhoneInfoArray.getJSONObject(i);
        subPhones.add(subPhoneInfo.getString("subphone"));
      }

      System.out.println("查询用户信息接口返回subPhones:"+ String.join(",",subPhones));

    }catch (Exception e){
      e.printStackTrace();
    }

  }
