Java Spring RestTemplate在使用授权标头发送时出现401未经授权的错误

我试图用下面的代码在我的SpringREST应用程序中点击一个MicrosoftFlowPostURL，但它给了我401错误。 我的代码：

是因为我的目标url是https，而我的本地主机是http吗

---

有人能告诉我出了什么问题吗？

有两点可供您检查此问题：

如果目标服务器是http服务器，则不应在url中使用https

确保

authorization

值为

base64

编码

更新：

由于目标服务器是https服务器，问题在于您没有将

ssl

info配置到

RestTempalte

中。您可以参考以下代码段以获取ssl restTemplate：

@Configuration
public class RestClientConfig {
    @Bean
    public RestOperations restOperations(ClientHttpRequestFactory clientHttpRequestFactory) throws Exception {
        return new RestTemplate(clientHttpRequestFactory);
    }

    @Bean
    public HttpComponentsClientHttpRequestFactory clientHttpRequestFactory(HttpClient httpClient) {
        return new HttpComponentsClientHttpRequestFactory(httpClient);
    }

    @Bean
    public HttpClient httpClient(@Value("${keystore.file}") String file, @Value("${keystore.pass}") String password) throws Exception {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        FileInputStream inStream = new FileInputStream(file);
        try {
            trustStore.load(inStream, password.toCharArray());
        } finally {
            inStream.close();
        }

        SSLContext sslcontext =
                SSLContexts.custom().loadTrustMaterial(trustStore, new TrustSelfSignedStrategy()).build();
        SSLConnectionSocketFactory sslsf =
                new SSLConnectionSocketFactory(sslcontext, new String[]{"TLSv1.2"}, null,
                                               null);
        return HttpClients.custom().setSSLSocketFactory(sslsf).build();
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

测试用例：

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = RestClientConfig.class)
public class RestClientTest {

    @Autowired
    private RestOperations rest;

    private HttpHeaders getHeaders(){
        String plainCredentials="admin:admin";
        String base64Credentials = Base64.getEncoder().encodeToString(plainCredentials.getBytes());

        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + base64Credentials);
        return headers;
    }

    @Test
    public void test() {
        HttpEntity<String> request = new HttpEntity<String>(getHeaders());
        ResponseEntity<String> response = rest.exchange(url, HttpMethod.GET, request, String.class);
        System.out.println(response.getBody());
    }
}

@RunWith（SpringRunner.class）
@ContextConfiguration（classes=RestClientConfig.class）
公共类RestClientTest{
@自动连线
私人休息；
私有HttpHeaders getHeaders（）{
String plainCredentials=“admin:admin”；
字符串base64Credentials=Base64.getEncoder（）.encodeToString（plainCredentials.getBytes（））；

}
@试验
公开无效测试（）{
HttpEntity请求=新的HttpEntity（getHeaders（））；
ResponseEntity response=rest.exchange（url，HttpMethod.GET，request，String.class）；
System.out.println（response.getBody（））；
}
}

在哪一点引发异常？在RestTemplate中或在输入方法之前？在“RestTemplate.exchange”处，它是Microsoft Flow的REST URL，是https，授权中也包含base64编码值。仍然存在相同的问题…现在我遇到此错误，我不知道任何SSL操作或技巧，请帮助<代码>严重：路径为[/inventoryhooks]的上下文中Servlet[webhooks]的Servlet.service（）引发异常[请求处理失败；嵌套异常为org.springframework.web.client.ResourceAccessException:请求发布时发生I/O错误”https://prod-03.centralindia.logic.azure.com/workflows/a"：sun.security.validator.validator异常：PKIX路径生成失败：sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径
