如何使用 REST API 与 java 连接 JIRA？
How connection with JIRA using RESTAPI with java?
我的任务是使用 RESTAPI 在 java 中建立与 JIRA 的连接。我遇到 SSL 安全证书错误。我已经尝试了很多次并查看了 google，但我没有找到任何解决我的问题的方法。谁能帮我解决这个错误？

HttpsURLConnection 默认使用 JDK 可信证书来验证服务器证书是否已知和可信。如果它在那边，它不会抛出 SSLHandshakeException
Jira 当前具有以下证书链：
您可以通过在初始化 HttpsURLConnection 后添加断点轻松验证您的 HttpsURLConnection 是否具有受信任的证书，请参见下面的示例：
所以我的假设是，在您的情况下，JDK 信任库中不存在证书。你可以做的是提取 Jira 证书，就像这里显示的那样：Using openssl to get the certificate from a server 后记要么将它导入到 cacert 文件中：$JAVA_HOME/lib/security/cacerts。但我认为为您的 HttpsUrlConnection 提供自定义 ssl 配置会更好，因为我认为它更易于维护。但是这两个选项都可以。
因此，以下代码片段适用于使用自定义 trustore 时的选项 2：

public class App {
public static void main(String[] args) throws Exception {
Path trustStorePath = Paths.get("/path/to/your/truststore.jks");
char[] trustStorePassword = "my-password".toCharArray();
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
try(InputStream inputStream = Objects.requireNonNull(Files.newInputStream(trustStorePath))) {
trustStore.load(inputStream, trustStorePassword);
}
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(trustStore);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustManagerFactory.getTrustManagers(), null);
SSLSocketFactory socketFactory = sslContext.getSocketFactory();
URL url = new URL("https://jira.atlassian.com/rest/api/latest/issue/JRA-9");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(socketFactory);
connection.setRequestProperty("accept", "application/json");
try(InputStream inputStream = connection.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader)) {
String responseBody = bufferedReader.lines().collect(Collectors.joining(System.lineSeparator()));
System.out.println(responseBody);
}
}
}
或者您可以在没有文件系统中的自定义信任库的情况下内联执行所有操作，如下所示。通过这种方式，您将根 ca 作为 pem，即 DigiCert High Assurance EV ROOT CA 并以编程方式将其加载到您的内存信任库中。

byte[] decodedCertificate = Base64.getDecoder().decode(certificateContent);
try(ByteArrayInputStream certificateAsInputStream = new ByteArrayInputStream(decodedCertificate);
BufferedInputStream bufferedCertificateStream = new BufferedInputStream(certificateAsInputStream)) {
