如何使用Spring5 WebClient支持HTTP代理？

Question

我使用的是Spring5 WebClient。我想知道是否可以将它配置为使用HTTP代理，或者是否有方法可以更改它的默认配置来这样做。

Answer 1

这是底层客户端库应该支持的东西。

使用Reactor Netty时，您可以执行以下操作：

HttpClient httpClient = HttpClient.create()
            .tcpConfiguration(tcpClient ->
                    tcpClient.proxy(proxy -> proxy.type(ProxyProvider.Proxy.HTTP).host("myproxyhost")));
ReactorClientHttpConnector connector = new ReactorClientHttpConnector(httpClient);
WebClient client = WebClient.builder().clientConnector(connector).build();

Answer 2

“tcpConfiguration”已弃用。所以改用了这部分代码。

  HttpClient httpClient =
            HttpClient.create()
                    .proxy(proxy -> proxy.type(ProxyProvider.Proxy.HTTP)
                            .host(sasConfig.getProxyHost())
                            .port(Integer.parseInt(sasConfig.getProxyPort())));

    ReactorClientHttpConnector connector = new ReactorClientHttpConnector(httpClient);

    WebClient webClient =  WebClient.builder().clientConnector(connector).build();
