restTemplate get 带pem证书 请求怎么写

您可以使用以下代码来使用 restTemplate 发送带有 pem 证书的 GET 请求：

RestTemplate restTemplate = new RestTemplateBuilder()
        .additionalInterceptors(new ClientHttpRequestInterceptor() {
            @Override
            public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
                request.getHeaders().add("Authorization", "Bearer " + token);
                return execution.execute(request, body);
            }
        })
        .build();

KeyStore keyStore = KeyStore.getInstance("PKCS12");
keyStore.load(new FileInputStream(new File("path/to/certificate.p12")), "password".toCharArray());

SSLContext sslContext = SSLContextBuilder
        .create()
        .loadKeyMaterial(keyStore, "password".toCharArray())
        .build();

HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(HttpClients.custom().setSSLContext(sslContext).build());

restTemplate.setRequestFactory(requestFactory);

ResponseEntity<String> response = restTemplate.exchange("https://example.com/api", HttpMethod.GET, null, String.class);

请注意，您需要将 "path/to/certificate.p12" 替换为您的 pem 证书的路径，将 "password" 替换为您的证书密码，将 "https://example.com/api" 替换为您要发送请求的 URL。
