我在 ReSTLet 2.4.2 java 中创建了一个 API,一切正常。 当我尝试在 ServerResource 文件中调用另一个 API 作为客户端时,出现此错误。
这是我作为客户端代码调用 API:
Client client = new Client(new Context(), Protocol.HTTPS);
client.getContext().getParameters().add("useForwardedForHeader","false");
ClientResource cr = new ClientResource("https://www.examples.com");
try{
cr.get(MediaType.APPLICATION_ALL).write(System.out);
} catch(ResourceException | IOException e) { e.printStackTrace(); }
我遇到的错误:
The protocol used by this request is not declared in the list of client connectors. (HTTPS/1.1). In case you are using an instance of the Component class, check its "clients" property.
我尝试在 pom.xml/maven 中添加 httpclient 库,但没有成功
<dependency>
<groupId>org.restlet.jse</groupId>
<artifactId>org.restlet.ext.httpclient</artifactId>
<version>2.4.0</version>
</dependency>
最佳答案
您的问题是您需要为您的 ReSTLet http 客户端配置 HTTPS 连接器。
我为您制作了这个简单的示例项目restlet https server/client sample
在此示例中,您有一个示例 HTTPS 服务器,其中包含带有自签名证书的 keystore (用于测试目的)以及配置了相同 keystore /证书的 HTTPS 客户端。
客户端代码示例:
private static final String url = "https://localhost:8443/";
public static void main(String[] args) {
System.out.println("Sending HTTP GET request to " + url);
// Add your HTTPS specifications
String file = "keystore-dev.jks";
String keystorePwd = "localhost";
String keyPwd = "localhost";
File keystoreFile = new File(file);
if (keystoreFile.exists()) {
Request request = new Request(Method.GET, url);
System.setProperty("javax.net.ssl.trustStore", keystoreFile.getAbsolutePath());
System.setProperty("javax.net.ssl.trustStorePassword", keystorePwd);
System.setProperty("javax.net.ssl.keyStore", keystoreFile.getAbsolutePath());
System.setProperty("javax.net.ssl.keyStorePassword", keystorePwd);
Client client = new Client(new Context(), Protocol.HTTPS);
client.getContext().getParameters().add("sslContextFactory",
"org.restlet.engine.ssl.DefaultSslContextFactory");
client.getContext().getParameters().add("keystoreType", "JKS");
client.getContext().getParameters().add("keystorePath", keystoreFile.getAbsolutePath());
client.getContext().getParameters().add("keystorePassword", keystorePwd);
client.getContext().getParameters().add("keyPassword", keyPwd);
Response resp = client.handle(request);
System.out.println("Service response code: " + resp.getStatus());
try {
System.out.println("Service response body: " + resp.getEntity().getText());
} catch (IOException e) {
System.out.println("Error reading response");
}
} else {
System.err.println("Error keystore not found");
}
}
客户端 pom.xml 依赖项:

创建测试 keystore 的示例命令行:
keytool -genkey -alias localhost -keyalg RSA -keysize 2048 -keypass localhost -storepass localhost -keystore keystore-dev.jks
有关更多信息,请阅读 Restlet- Client connectors和 Restlet - HTTPS .
您可以使用Server/Client Resources也是。
