Java中调用第三方接口的简单方法post和get请求

//这是springboot下写的，采用注解@Component注入的post请求

//写出对应的实体类进行结果的接收
public class PointDto {
          
   
    private String PointText;


@Component
public class url {
          
   

//连接统一管理，一般放在application-dev.yml下面通过下面的方法获取
    @Value("${gateway.getKnowledgePoint}")
    private String Url;
//RestTemplate 第三方接口运用这个方法进行调用
    public String Point(String  questionText) {
          
   

        RestTemplate restTemplate = new RestTemplate();

        String url = getKnowledgePointUrl;
        String knowledge = restTemplate.postForObject(url, questionText, String.class);

        return knowledge;
    }

get请求

同样对应实体类的接收

public class PointDto {
          
   
    private String PointText;

@Component
public class QuestionByIdUtils {
          
   

    @Value("${gateway.getQuestionById}")
    private String getQuestionByIdUrl;
    public String qusetionById(Integer questionId) {
          
   

        RestTemplate restTemplate1 = new RestTemplate();
        String url = getQuestionByIdUrl;
        String strs = url + questionId;
//IdDto.class对应的实体类
        IdDto IdDto = restTemplate1.getForObject(strs, IdDto.class);
        //对结果进行获取
        Map<String,Object> data1 = (Map<String,Object>)IdDto.getData();

        return (String) data1.get("Title");

    }


}

//get
public class QuestionTypeUtil {
          
   

    @Value("${gateway.getType}")
    private String getTypeUrl;

    public String qusetionTypes(String Text){
          
   


        //第三方题型接口
        RestTemplate restTemplate1 = new RestTemplate();

        String url = getTypeUrl;
        String strs = url + Text;
        // 对str类型的转化，因为报异常
        UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(strs);
        UriComponents uriComponents = builder.build();
	//获取连接对象        
        QuestionTypeDto questionTypeDto = restTemplate1.getForObject(uriComponents.toUri(), TypeDto.class );

//结果的获取
        List<List<String>> classes = TypeDto.getClasses();

        List<String> s = classes.get(0);
        String s1 = s.get(0);
        return s1;
    }

}

#post请求两个参数

@Component
public class QuestionsTextUtils {
          
   
    public Map<String, Object> qusetionByMes(List<Map<String,String>> questionText, Integer num) {
          
   

        HttpHeaders headers = new HttpHeaders();
        MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
        headers.setContentType(type);
        headers.add("Accept", MediaType.APPLICATION_JSON.toString());
        HttpEntity<List<Map<String,String>>> mapHttpEntity = new HttpEntity<>(questionText, headers);

        RestTemplate restTemplate1 = new RestTemplate();
        String url = "http://testaliyun.eebbk.net/social-search/test/search/text?subject=";
        String strs = url + num;

//        String s = restTemplate1.postForObject(strs, mapHttpEntity, String.class);
        Map<String, Object> s = restTemplate1.postForObject(strs, mapHttpEntity, Map.class);
        return s ;
    }

.控制层

//@RequestBod 返回集合必须加这个注解
    @PostMapping("/getQuestionIds")
    @ApiOperation(value = "", notes = "")
    public ResponseBean<Map<String, Object>> findAllData(@RequestBody List<Map<String,String>> questionText, Integer num) {
          
   

        try {
          
   
           return new ResponseBean(questionsTextUtils.qusetionByMes(questionText, num));

        }catch (Exception e){
          
   
            log.error("获取试题id失败");
            e.printStackTrace();
        }
        return  new ResponseBean<>();
    }
