Springboot调用第三方接口
方式一:使用RestTemplate请求第三方接口
配置yaml配置文件
server:
port: 8081
# 第三方接口
interfaceurl:
REQUEST_URL: http://192.168.5.178:8080/query/
RestTemplate配置类
/** * RestTemplate配置类 */
@Configuration
public class RestTemplateConfig {
@Autowired
private RestTemplateBuilder restTemplateBuilder;
@Bean
public RestTemplate restTemplate(){
return restTemplateBuilder.build();
}
}
接口类
@Controller
@Slf4j
public class InterfaceController {
@Autowired
private InterfaceServiceImpl interfaceService;
//去请求第三方的key
@RequestMapping("/select/{key}")
@ResponseBody
public String queryInterface(@PathVariable("key") String key){
log.info("传递进来的key为===>"+key);
//使用service调用第三方接口,并返回对象
Status status = interfaceService.queryByKey(key);
//将对象转化为json字符串
String s = JSONObject.toJSONString(status);
return s;
}
}
service接口类
public interface InterfaceService {
//根据key查询
Status queryByKey(String key);
}
service接口实现类
@Service
@Slf4j
public class InterfaceServiceImpl implements InterfaceService {
@Autowired
private InterfaceUrl interfaceUrl;
@Autowired
private RestTemplate restTemplate;
@Override
public Status queryByKey(String key) {
//用RestTemplate请求第三方接口
ResponseEntity<String> responseEntity = restTemplate.getForEntity(interfaceUrl.getREQUEST_URL() + key, String.class);
// log.info("这个forEntity=====>" + responseEntity);
//获取请求body
String body = responseEntity.getBody();
ObjectMapper objectMapper = new ObjectMapper();
Status status = new Status();
try {
//转化为对象
status = objectMapper.readValue(body, Status.class);
} catch (JsonProcessingException e) {
e.printStackTrace();
// log.info("转化异常");
}
return status;
}
}
三个实体类
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Status implements Serializable {
private Integer code;
private String msg;
private List<AutoComplete> data;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
@Component
@ConfigurationProperties("interfaceurl")
public class InterfaceUrl {
private String REQUEST_URL;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
public class AutoComplete implements Serializable {
private String value;
private String buildID;
}
方式二:采用HttpURLConnection工具请求第三方接口
工具类HttpUtil
public class HttpUtil {
/** * 模拟浏览器的请求 * * @param httpURL 发送请求的地址 * @param params 请求参数 * @return * @throws Exception */
public static String sendHttpRequest(String httpURL, Map<String, String> params) throws Exception {
//建立URL连接对象
URL url = new URL(httpURL);
//创建连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//设置请求的方式(需要是大写的)
conn.setRequestMethod("POST");
//设置需要输出
conn.setDoOutput(true);
//判断是否有参数.
if (params != null && params.size() > 0) {
StringBuilder sb = new StringBuilder();
for (Entry<String, String> entry : params.entrySet()) {
sb.append("&").append(entry.getKey()).append("=").append(entry.getValue());
}
//sb.substring(1)去除最前面的&
conn.getOutputStream().write(sb.substring(1).toString().getBytes("utf-8"));
}
//发送请求到服务器
conn.connect();
//获取远程响应的内容.
String responseContent = StreamUtils.copyToString(conn.getInputStream(), Charset.forName("utf-8"));
conn.disconnect();
return responseContent;
}
/** * 模拟浏览器的请求 * * @param httpURL 发送请求的地址 * @param jesssionId 会话Id * @return * @throws Exception */
public static void sendHttpRequest(String httpURL, String jesssionId) throws Exception {
//建立URL连接对象
URL url = new URL(httpURL);
//创建连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//设置请求的方式(需要是大写的)
conn.setRequestMethod("POST");
//设置需要输出
conn.setDoOutput(true);
conn.addRequestProperty("Cookie", "JSESSIONID=" + jesssionId);
//发送请求到服务器
conn.connect();
conn.getInputStream();
conn.disconnect();
}
}
测试代码
@Test
void contextLoads() throws Exception {
String url="https://way.jd.com/jisuapi/weather";
Map<String,String> hashMap=new HashMap<>();
hashMap.put("city","汕头");
hashMap.put("appkey","");
String s = HttpUtil.sendHttpRequest(url, hashMap);
System.out.println(s);
}
注意appkey的value值需要有参数,这里测试用的接口时京东万象的天气接口
