看了下spring webflux的知識點颁独，隨便寫了個小工具去解析youtube上的視頻地址，然后就有了設(shè)置代理和ssl部分的實踐吨枉，記錄一下

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

一 . webclient設(shè)置SSL

SslContext sslContext = SslContextBuilder
    .forClient()
    .trustManager(InsecureTrustManagerFactory.INSTANCE)
    .build();

ReactorClientHttpConnector connector = new ReactorClientHttpConnector(options -> options.sslContext(sslContext)) ;

WebClient client = WebClient.builder().clientConnector(connector)
    .baseUrl("https://www.youtube.com")
    .build();

二 . webclient設(shè)置代理

SslContext sslContext = SslContextBuilder
    .forClient()
    .trustManager(InsecureTrustManagerFactory.INSTANCE)
    .build();

ReactorClientHttpConnector connector = new ReactorClientHttpConnector(options -> options
    .httpProxy(addressSpec -> addressSpec
        .address(new InetSocketAddress("127.0.0.1", 1080)))
    );

WebClient client = WebClient.builder().clientConnector(connector)
    .baseUrl("https://www.youtube.com")
    .build();

三 . get請求

// 比如訪問 http://www.xxx.com/playlist?param=xxxx
WebClient client = WebClient.builder()
        .baseUrl("http://www.xxx.com")
        .build();
WebClient.ResponseSpec responseSpec = client
        .get()
        .uri(uriBuilder -> uriBuilder
                .path("playlist") // 子路徑
                .queryParam("param", "xxxx") // 參數(shù)
                .build())
        .acceptCharset(StandardCharsets.UTF_8)
        .accept(MediaType.ALL)
        .retrieve();
// 返回Mono還是Flux 要根據(jù)接口實際情況調(diào)整
 Mono<String> objectMono = responseSpec.bodyToMono(String.class);
 // Flux<String> objectFlux = responseSpec.bodyToFlux(String.class);

四 . post請求（form表單參數(shù)）

// 比如訪問 http://www.xxx.com/postReq  , 用form表單方式傳參
WebClient client = WebClient.builder()
        .baseUrl("http://www.xxx.com")
        .build();
WebClient.ResponseSpec responseSpec = client
        .post()
        .uri("postReq")
        .body(BodyInserters.fromFormData("mediaurl", url)) // form表單參數(shù)蹦渣，可以增加多個參數(shù)
        .retrieve();
Mono<String> objectMono = responseSpec.bodyToMono(String.class);

五 . 通過URL對象獲取請求信息

String url = "http://www.xxx.com/getReq?param=abc&param2=cde" ;
URL finalCheckUrl = new URL(url);
WebClient.ResponseSpec retrieve = client.get()
        .uri(uriBuilder -> uriBuilder
                .scheme(finalCheckUrl.getProtocol())
                .host(finalCheckUrl.getHost())
                .path(finalCheckUrl.getPath())
                .query(finalCheckUrl.getQuery())
                .build())
        .retrieve();

注意： 如果請求的地址都是同一個host, 把webclient 抽取出來，不要每次請求都去新建webclient .
