java - 使用 JAVA 项目或 AEM 实现 Akamai CCU V3 快速清除

Question

有没有人尝试过将 Java 代码从 CCU V2 集成到 CCU V3 并进行快速清除。我阅读了文档，但无法理解基于 java 的项目需要做什么。在 Akamai 控制台中配置客户端后，我们如何编写代码来访问和清除。非常感谢任何帮助。

谢谢，图沙尔

一般方法是编写一些代码，向快速清除端点发出 HTTP 请求。

这是一个例子:

import com.akamai.edgegrid.auth.*;
//other imports

public void callAkamaiFastPurgeForUrls(Set<String> urlsToPurge) throws URISyntaxException, IOException, RequestSigningException {
    if(!urlsToPurge.isEmpty()) {
        int status;
        String json = getPurgeJson(urlsToPurge);
        HttpRequest signedRequest = getHttpRequest(json, compProperty);
        HttpResponse response = signedRequest.execute();

        status = response.getStatusCode();

        if (status == 201) {
            //handle success responses as you see fit
        } else {
            //handle non-success responses as you see fit
        }
    }
}

private static String getPurgeJson(Set<String> pathsToPurge) {
    //your code to turn the list of urls into JSON in this format:
    //{"objects":["https://www.yourdomain.com/page1.html","https://www.yourdomain.com/page2.html"]}

    return //JSON string such as the example above
}


private HttpRequest getHttpRequest(String json, Dictionary<String, Object> dispatcherAndAkamaiServletProperties) throws URISyntaxException, IOException, RequestSigningException {
    String hostName = yourCodeToFetchConfigValues("hostname");
    String accessToken = yourCodeToFetchConfigValues("accesstoken");
    String clientToken = yourCodeToFetchConfigValues("clienttoken");
    String clientSecret = yourCodeToFetchConfigValues("clientsecret");
    String apiUrl = yourCodeToFetchConfigValues("apiurl");
    String proxyServer = yourCodeToFetchConfigValues("proxyhostakamai");
    int proxyPort = yourCodeToFetchConfigValues("proxyport");

    HttpTransport httpTransport = new NetHttpTransport.Builder()
            .setProxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyServer, proxyPort))).build();

    HttpRequestFactory requestFactory = httpTransport.createRequestFactory();

    URI uri = new URI(HTTPS, hostName, apiUrl, null, null);
    HttpContent body = new ByteArrayContent("application/json", json.getBytes());
    HttpRequest request = requestFactory.buildPostRequest(new GenericUrl(uri), body);
    HttpHeaders headers = request.getHeaders();
    headers.set("Host", hostName);
    ClientCredential credential = new DefaultCredential(clientToken, accessToken, clientSecret);
    RequestSigner signer = new EdgeGridV1Signer(Collections.emptyList(), 1024 * 2);

    return signer.sign(request, credential);
}

此外，您可能需要更新您的信任库以包含您正在调用的 Akamai 端点的证书，以便可以进行 SSL 通信。
