嗨，我在我的 Spring Boot 项目中遇到代理 407 身份验证错误。我在这些场景中尝试了两种场景，proxyHost 和 proxyPort 值正在工作，但用户名和密码无效？有人遇到这种情况吗？在我的本地机器上，当我提供端口和主机并且不提供用户名密码，它适用于我的本地用户和工作，但我以错误的格式提供用户名和密码以查看其效果？我没有效果。同样在服务器中，我得到了 407 身份验证代理异常。如何在 spring boot 中传递代理用户名和密码？谢谢

我添加了 jvm 参数但 proxyuser 和 proxyPassword 没有效果

-Dhttps.proxyHost=something -Dhttps.proxyPort=5555-Dhttps.proxyUser=xxx -Dhttps.proxyPassword=yyy

我还向 myresttemplate 构建器添加了一些代理代码，但它没有效果。

RestTemplate restTemplate=new RestTemplateBuilder()
            .build();
        int proxyPortNum =5555;
        String proxyHost="something";

         CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(new AuthScope(proxyHost, proxyPortNum), new UsernamePasswordCredentials("myname", "333"));

         HttpClientBuilder clientBuilder = HttpClientBuilder.create();
        clientBuilder.useSystemProperties();
        clientBuilder.setProxy(new HttpHost(proxyHost, proxyPortNum));
        clientBuilder.setDefaultCredentialsProvider(credsProvider);
        clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());
         CloseableHttpClient client = clientBuilder.build();
 HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
    factory.setHttpClient(client);

    restTemplate.setRequestFactory(factory);

你应该尝试这样的事情：-----

 private RestTemplate createRestTemplate() throws Exception {
        final String username = "myname";
        final String password = "333";
        final String proxyUrl = "something";
        final int port = 5555;
    
        HttpHost myProxy = new HttpHost(proxyUrl, port);
       HttpClientBuilder clientBuilder = HttpClients.custom();
List<Header> headers = new ArrayList<>();
BasicHeader authHeader = new BasicHeader("Authorization",base64authUserPassword());
headers.add(authHeader);
RequestDefaultHeaders reqHeader = new RequestDefaultHeaders(headers);
clientBuilder.addInterceptorLast(reqHeader);
        clientBuilder.setProxy(myProxy).disableCookieManagement();
    
        HttpClient httpClient = clientBuilder.build();
        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
        factory.setHttpClient(httpClient);
    
        return new RestTemplate(factory);
    }

public String base64authUserPassword() {
byte[] baseencode = Base64.getEncoder().encode((username + ":" + password).getBytes());
return "Basic " + new String(baseencode);
}

希望它能解决您的问题。
