本文介绍RestTemplate访问Rest

demo

package com.springlearn.learn;

import java.util.Arrays;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
public class DemoApplication {

	public static void main(String[] args) {
		HttpHeaders headers = new HttpHeaders();
		headers.setAccept(Arrays.asList(new MediaType[]{MediaType.APPLICATION_JSON_UTF8}));

		// Get
		// HttpEntity<String> entity = new HttpEntity<String>(headers);
		// RestTemplate restTemplate = new RestTemplate();
		// ResponseEntity<String> response = restTemplate.exchange("https://www.baidu.com/s?wd=a", HttpMethod.GET, entity,String.class);

		// Post
		// HttpEntity<Object> entity = new HttpEntity<>(new Object[]{"1"}, headers);
		// RestTemplate restTemplate = new RestTemplate();
		// Object response = restTemplate.postForObject("https://www.baidu.com/s?wd=a", entity, Object.class);

		// Put 和Post类似
		// 使用put方法即可
		// 或者使用restTemplate.exchange("...", HttpMethod.PUT, entity, String.class);

		// Delete 直接delete即可

		System.out.println("结果："+response);

		SpringApplication.run(DemoApplication.class, args);
