使用springboot RestTemplate調用外部API，拋出異常

Question

我正在嘗試使用 Springboot Resttemplate 消耗 REST API。 這在本地系統上測試時工作正常，我可以使用數據。 但是當我在 Heroku 上部署相同的服務時，它會拋出異常。 我無法弄清楚它有什么問題。 我是 Heroku 環境的新手。 如果我遺漏任何東西，請幫忙

代碼：

@Bean
    public RestTemplate restTemplate() {
        CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                .build();
        HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);
        return new RestTemplate(requestFactory);
    }

public void checkAvailability(VaccineRequest vaccineRequest) {
        String url = findByPinUrl.replace("#pin#", vaccineRequest.getPinCode()).replace("#date#", vaccineRequest.getDate());

        log.info("API-SETU-URL - {}", url);

        HttpHeaders headers = new HttpHeaders();
        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        headers.add("user-agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36");
        HttpEntity<String> entity = new HttpEntity<>("parameters", headers);

        ResponseEntity<Response> responseObj = null;

        try {
            responseObj = restTemplate.exchange(url, HttpMethod.GET, entity, Response.class);
        } catch (RestClientException e) {
            log.info("Exception while invoking apisetu url : {}", e);
        }


        log.info("Response : {}", responseObj);
}

Answer 1

禁止，因為服務器不允許您的請求。 API 僅限於非印度 IP 地址。 這是最可能的原因，因為您的 heroku 部署可能超出了印度 IP 范圍。
