java - 从传递身份验证参数的 URL 加载 JSON 数据

Question

我必须从 URL 中使用 JSON，我正在使用 Springboot 和 jackson，当我发帖时，我在 header 中发送一些身份验证信息，API 需要 SECRETKEY + ACCESSKEY + 日期，我有所有这些信息要发送

 public void sendListPayload(int count, List object, String controller) throws NoSuchAlgorithmException, IOException {

        Control type = Control.valueOf(controller);
        String endereco = getAdress(type);
        String payloadSecure = "";
        RestTemplate restTemplate = new RestTemplate();
        String url = "http://adress/site.php";
        HttpHeaders headers;
        String payload = convertListToJson(object);
        headers = getHeaders(count, payload);
        headers.setContentType(MediaType.APPLICATION_JSON);
        HttpEntity<String> entity = new HttpEntity<>(payloadSecure, headers);
         String answer = restTemplate.postForObject(url, entity, String.class);
         log.info(answer);
    }

获取标题

public HttpHeaders getHeaders(int sizeRecords, String payloadSecure) throws NoSuchAlgorithmException {
        HttpHeaders headers = new HttpHeaders();
        String signature = "";
        signature = payloadSecure + SECRETKEY + ACCESSKEY + getISODate();
        String fullSignature = FIRSTPAYLOAD + getISODate() + ":" + Useful.toSha(signature);
        headers.add("HEADER", fullSignature);
          return headers;

我要读取的缩小 JSON 将如下所示

[{"relatorioID":"1852","professorID":"7","alunoID":"37","turmaID":"44","bimestre":"0","data":"2014-06-05 07:51:49","situacao":"1"},
{"relatorioID":"1854","professorID":"7","alunoID":"37","turmaID":"44","bimestre":"0","data":"2014-06-05 07:51:55","situacao":"1"}]

我已经有一个具有相同字段的对象来使用 JSON 数据实例化我对java和springboot很陌生，如何通过secretkey和accesskey？是在get方法的头部吗？

然后我必须使用 jackson ... 将接收到的 JSON 转换为对象列表，以将它们插入到本地数据库中。

Answer 1

因此，重点是您需要清楚 API 规范，即您的 API 期望以哪种格式请求请求。无论如何，回答下面的问题代码可以帮助您在 header 中发送身份验证参数并处理响应。

 import org.springframework.web.client.RestTemplate;
 import org.springframework.web.util.UriComponents;
 import org.springframework.web.util.UriComponentsBuilder;
 import org.springframework.http.ResponseEntity;
 //some more class import may be you need to add
  try {

    UriComponents uriComponents = 
     UriComponentsBuilder.newInstance().scheme("https").host(host).path(url).
     queryParam("url_param1", value).queryParam("another_param", 
     value).build().encode();

    HttpHeaders headers = new HttpHeaders();
    headers.add("SECRETKEY", value);
    HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
    ResponseEntity<List<MyResponseObject>> response = restTemplate.exchange(uriComponents.toUri(), HttpMethod.GET, entity, new ParameterizedTypeReference<List<MyResponseObject>>());

    List<MyResponseObject > responses= response.getBody();

  } catch (Exception e) {
     logger.error(e.getMessage());
  }

创建 MyResponseObject 类来绑定(bind)您的响应 json 属性

public class MyResponseObject {

    @JsonProperty("relatorioID")
    private String relatorioID;



    @JsonProperty("professorID")
    private Integer professorID;

    ...


    //getter //setter
} 

我希望这将帮助您将参数绑定(bind)在 header 上，并通过在 URL 中编码查询参数来发送。一旦您获得 MyResponseObject 对象列表形式的响应。
