    WebClient属于WebFlux的一部分,是一组非阻塞、响应式API,主要用于HTTP请求。WebFlux的客户端和服务端在HTTP通信方面依赖的是同一套非阻塞模块。
    默认情况下,WebClient底部通信使用的是Reactor Netty框架,同时它也支持其他通信框架使用插件式的方式整合进来(使用ClientHttpConnector)。
    1、配置
    在代码中创建WebClient 可以通过以下静态方法:

    WebClient.create()
    
    WebClient.create(String baseUrl)
    

    以上方法使用的是默认配置下的Reactor Netty的HttpClient ,并且需要依赖:io.projectreactor.netty:reactor-netty
    WebClient.builder()方法也提供以下几个参数可供用户配置:

    uriBuilderFactory:
    defaultHeader: HTTP请求头
    
    defaultCookie: 设置Cookies.
    
    defaultRequest
    
    filter: 客户端过滤器,可以对每个请求进行统一的处理
    
    exchangeStrategies: HTTP message reader/writer customizations.
    
    clientConnector: HTTP client library settings.
    

    配置示例:

    ExchangeStrategies strategies = ExchangeStrategies.builder()
                .codecs(configurer -> {
                    // ...
                })
                .build();
    
        WebClient client = WebClient.builder()
                .exchangeStrategies(strategies)
                .build();
    

    WebClient 实例一旦被创建,本身是无法修改的;但可以通过创建一个“副本”的方法进行修改:

    WebClient client1 = WebClient.builder()
                .filter(filterA).filter(filterB).build();
    
        WebClient client2 = client1.mutate()
                .filter(filterC).filter(filterD).build();
    
        // client1 has filterA, filterB
    
        // client2 has filterA, filterB, filterC, filterD

    网页上有插入文件到数据库,或者从数据库中导出文件webClient连接.如果从网页上下载数据用到webClient 的downloadfile() ,其中这里有两个参数:你请求的url和我请求文件的保存位置。第二个:应用程序需要从web站点检索数据,为此要用到OpenRead方法,此方法返回一给Stream对象,然后Stream对象从数据流提取到内存中去
