【项目实战】使用Spring框架中的RestTemplate，实现HTTP请求的调用 RestTemplate是Spring框架中的一个HTTP客户端，它提供了一种方便的方式来发送HTTP请求并处理响应。阅读详情

POST

		//创建 restTemplate 对象
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add("authorization", token);
        httpHeaders.add("consumer-key", maerskAppKey);
        httpHeaders.setContentType(MediaType.parseMediaType("application/json; charset=UTF-8"));

       JSONObject.parseObject(JSONUtil.toJsonPrettyStr(mandatoryBookingApplyDTO)));
       //参数和头部信息封装到 HttpEntity
        HttpEntity<String> entity = new HttpEntity<>(JSONUtil.toJsonPrettyStr(mandatoryBookingApplyDTO), httpHeaders);
        //发送
        ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(this.bookingUrl, entity, JSONObject.class);
        log.info("状态码 : " + responseEntity.getStatusCodeValue() + "    回传参数:   " + responseEntity.getBody());

通用请求 PATCH

  RestTemplate restTemplate = new RestTemplate(requestFactory);

        // 4.设置RestTemplate参数(请求头和body)
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.parseMediaType("application/json; charset=UTF-8"));
        headers.add("authorization", token);
        headers.add("consumer-key", maerskAppKey);


        HashMap<String, Object> parameterMap = Maps.newHashMap();

        parameterMap.put("bookingStatus", "CANCELLED");
        parameterMap.put("contactName", "John Smith");


        String url = "url";
        HttpEntity<String> entity = new HttpEntity<>(JSON.toJSONString(parameterMap), headers);
        // 请求 HttpMethod.PATCH是PATCH请求 可以换成 GET POST DEL
        ResponseEntity<JSONObject> responseEntity = restTemplate.exchange(url, HttpMethod.PATCH, entity, JSONObject.class);
        log.info("返回结果: " + responseEntity.getBody() + responseEntity.getStatusCodeValue());
