我正在尝试在我的Sping Boot 应用程序中调用外部Rest API端点。我有一个API密钥，是我在将其用于我的Rest应用程序之前生成的。每当我尝试点击GET请求时，都会显示缺少API密钥403禁止错误。

我试着写这段代码来得到想要的输出。不幸的是无法做到。

@RequestMapping(value = {"/reports"}, method = {RequestMethod.GET, RequestMethod.POST}, produces = {MediaType.APPLICATION_JSON_VALUE})
    public ResponseEntity<Object> getCloudHealthReports(){
        logger.info("Inside get cloud health reporting function..!!!!");
        try {
            String apiKey = "abc-xyz-example-apikey-e215d82537ba";
            final String uri = "https://chapi.cloudhealthtech.com/olap_reports";
            RestTemplate restTemplate = new RestTemplate();
            
            URL url = new URL(uri);
            HttpURLConnection http = (HttpURLConnection)url.openConnection();
            
            http.setRequestProperty("Accept", "application/json");
            http.setRequestProperty(HttpHeaders.AUTHORIZATION, String.format("Bearer %s", apiKey));
            
            ResponseEntity<String> response = restTemplate.getForEntity(uri, String.class);
            
            return new ResponseEntity<>(response.getHeaders(), HttpStatus.OK);
            
        } catch (Exception e) {
            System.out.println(e.getMessage());
            e.printStackTrace();
            return new ResponseEntity<>("Error! Please try again later", HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }

jecbmhm31#

HttpURLConnection c = (HttpURLConnection) new URL("https://chapi.cloudhealthtech.com/olap_reports").openConnection();
c.setRequestProperty("Accept", "application/json");
c.setRequestProperty("Authorization", "Bearer abc-xyz-example-apikey-e215d82537ba");
try {
  System.out.println(c.getResponseCode() + ": " + new String(c.getInputStream().readAllBytes()));
} catch(Exception e) {
  System.out.println(c.getResponseCode() + ": " + new String(c.getErrorStream().readAllBytes()));
}

我得到：

403: {"error":"Unrecognized API key"}

这比“缺少”API键要好。也许可以尝试使用这个示例，一次改变一件事。
看看这个：Sending GET request with Authentication headers using restTemplate
您需要以特定于Spring的方式传递请求头。

您确定您为其余呼叫提供了正确的标题吗？
有一件事是可以的，那就是你的API会回答你，所以它工作正常，但不是很好。
如果可以的话，你可能也应该检查你的响应API中的日志。

ApiClient apiClient = new ApiClient();
apiClient.setBasePath("BASE_URL");
apiClient.setApiKeyPrefix("App");
apiClient.setApiKey("API_KEY");
return apiClient;

我试过这种方法，得到了预期的结果。

public ResponseEntity<Object> getCloudHealthReports() throws IOException{
        ResponseEntity<String> responseEntity = null;
        try {
            final String uri = "https://chapi.cloudhealthtech.com/olap_reports";
            RestTemplate restTemplate = new RestTemplate();
            HttpHeaders header = new HttpHeaders();
            header.set(HttpHeaders.AUTHORIZATION, "Bearer API-KEY");
            
            HttpEntity<String> requestEntity = new HttpEntity<String>("body",header);
            responseEntity = restTemplate.exchange(uri, HttpMethod.GET, requestEntity, String.class);
            
            String response = responseEntity.getBody();
            
            return new ResponseEntity<Object>(response, HttpStatus.OK);
            
        } catch (Exception e) {
            e.printStackTrace();
            
            return new ResponseEntity<Object>("Please try again later", HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
