我在我的 REST 服務中使用一個 REST API。當我從 Chrome 或 Postman 調用 API 時一切正常，但當我從我的應用程序調用時返回 Forbbiden 響應。PS：我正在使用 Java Spring Boot 項目。測試方法：public static void main(String[] args) { final String uri = "https://swapi.co/api/planets?search=Alderaan"; System.out.println(new RestTemplate().getForObject(uri, String.class));}生產：20:58:01.436 [main] DEBUG org.springframework.web.client.RestTemplate - HTTP GET swapi.co/api/planets?search=Alderaan 20:58:01.461 [main] DEBUG org.springframework.web.client.RestTemplate - Accept=[text/plain, application/json, application/*+json, */*]20:58:02.577 [main] DEBUG org.springframework.web.client.RestTemplate - Response 403 FORBIDDENException in thread "main" org.springframework.web.client.HttpClientErrorException$Forbidden: 403 Forbidden外部 API： https: //swapi.co/documentation

當我在標頭中指定一些“用戶代理”時，一切正常。
它似乎是對 CloudFlare 的限制： https://support.cloudflare.com/hc/en-us/articles/200170086-What-does-the-Browser-Integrity-Check-do-
我的應用程序的用戶代理是我的 Java 版本 (Java/1.8.0_151)。如果您嘗試使用此用戶代理，您將收到來自 CloudFlare 的限制訪問消息。
卷曲：
curl -H "User-Agent: Java/1.8.0_151" https://swapi.co/api/planets/?search=Alderaan
響應：訪問被拒絕 | swapi.co 使用 Cloudflare 來限制訪問
此代碼解決問題：
HttpHeaders headers = new HttpHeaders();
headers.add("user-agent", "Application");
HttpEntity<String> entity = new HttpEntity<>(headers);
String planetFound = restTemplate.exchange(findPlanetUri, HttpMethod.GET, entity, String.class).getBody();
另一個解決方案：
String planetFound = restTemplate.getForObject(findPlanetUri, String.class);
和
@Bean
public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) {
ClientHttpRequestInterceptor interceptor = (request, body, execution) -> {
request.getHeaders().add("user-agent", "Application");
return execution.execute(request, body);
};
return restTemplateBuilder.additionalInterceptors(interceptor).build();
}

您的代碼實際上對我有用：
public static void main(String[] args) {
final String uri = "https://swapi.co/api/planets?search=Alderaan";
System.out.println(new RestTemplate().getForObject(uri, String.class));
}
輸出是：
01:20:49.564 [main] DEBUG org.springframework.web.client.RestTemplate - HTTP GET https://swapi.co/api/planets?search=Alderaan
01:20:49.573 [main] DEBUG org.springframework.web.client.RestTemplate - Accept=[text/plain, application/json, application/*+json, */*]
01:20:51.177 [main] DEBUG org.springframework.web.client.RestTemplate - Response 200 OK
01:20:51.179 [main] DEBUG org.springframework.web.client.RestTemplate - Reading to [java.lang.String] as "application/json"

也許你在一分鐘或一小時內向服務發送了太多請求，他們已經開始阻止你的 IP / 用戶代理或其他任何東西。
