RestTemplate 調(diào)用外部 API 時(shí)被禁止（Cloudflare 服務(wù)器）

Java

翻翻過去那場雪 2023-05-10 15:42:03

我在我的 REST 服務(wù)中使用一個(gè) REST API。當(dāng)我從 Chrome 或 Postman 調(diào)用 API 時(shí)一切正常，但當(dāng)我從我的應(yīng)用程序調(diào)用時(shí)返回 Forbbiden 響應(yīng)。PS：我正在使用 Java Spring Boot 項(xiàng)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(chǎn)：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(dāng)我在標(biāo)頭中指定一些“用戶代理”時(shí)，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(yīng)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(yīng)：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(gè)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(shí)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"

{"count":1,"next":null,"previous":null,"results":[{"name":"Alderaan","rotation_period":"24","orbital_period":"364","diameter":"12500","climate":"temperate","gravity":"1 standard","terrain":"grasslands, mountains","surface_water":"40","population":"2000000000","residents":["https://swapi.co/api/people/5/","https://swapi.co/api/people/68/","https://swapi.co/api/people/81/"],"films":["https://swapi.co/api/films/6/","https://swapi.co/api/films/1/"],"created":"2014-12-10T11:35:48.479000Z","edited":"2014-12-20T20:58:18.420000Z","url":"https://swapi.co/api/planets/2/"}]}

也許你在一分鐘或一小時(shí)內(nèi)向服務(wù)發(fā)送了太多請求，他們已經(jīng)開始阻止你的 IP / 用戶代理或其他任何東西。
