 HTTP Interface

1. Spring 允许我们通过定义接口的方式，给任意位置发送 http 请求，实现远程调用，可以用来简化 HTTP 远程访问。需要webflux场景才可

   <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-webflux</artifactId>
   </dependency>

2. 定义接口

   public interface BingService {@GetExchange(url = "/search",accept="application/json")//请求的地址,接收json数据Mono<String> search(@RequestParam("area") String keyword,@RequsetHeader("Authorization") String auth);//在service里@GetExchange表示我要发一个请求参数叫"area"
   //和controller上不一样.
   }

3. 创建代理&测试

   @SpringBootTest
   class Boot05TaskApplicationTests {@Testpublic Mono<String> weather(String city) {//1、创建客户端WebClient client = WebClient.builder().baseUrl("https://cn.bing.com")//给哪发请求.codecs(clientCodecConfigurer -> {clientCodecConfigurer.defaultCodecs().maxInMemorySize(256*1024*1024);//响应数据量太大有可能会超出BufferSize，所以这里设置的大一点}).build();//2、创建工厂HttpServiceProxyFactory factory = HttpServiceProxyFactory.builder(WebClientAdapter.forClient(client)).build();//3、获取代理对象BingService bingService = factory.createClient(BingService.class);//BingService.class接口名//4、测试调用Mono<String> search = bingService.search(city,"APPCODE XXXXXXXX");return weather;}}

4. 生产模式----编写配置类config/WeatherConfiguration,@config

   @Bean
   WeatherInterface WeatherInterface(){
   //1、创建客户端WebClient client = WebClient.builder().baseUrl("https://cn.bing.com")//给哪发请求.codecs(clientCodecConfigurer -> {clientCodecConfigurer.defaultCodecs().maxInMemorySize(256*1024*1024);//响应数据量太大有可能会超出BufferSize，所以这里设置的大一点}).build();//2、创建工厂HttpServiceProxyFactory factory = HttpServiceProxyFactory.builder(WebClientAdapter.forClient(client)).build();//3、获取代理对象WeatherInterface WeatherInterface = factory.createClient(WeatherInterface.class);//BingService.class接口名
   return WeatherInterface;
   }

5. WeatherService

   @Autowired
   WeatherInterface WeatherInterface//4、测试调用Mono<String> weather = WeatherInterface.search(city,"APPCODE XXXXXXXX");return weather;
