Spring AppRoleAuthentication出错-URI不是绝对的

Question

我正在尝试使用AppRole身份验证从vault中检索机密。但我得到了错误：

java.lang.IollegalArgumentException：URI不是绝对

我所做的是创建一个vaultEndpoint，然后根据选择的方法使用令牌身份验证或AppRole身份验证。令牌身份验证没有问题，但每当我尝试检索机密，甚至让vaultToken使用AppRole登录时，就会出现URI不是绝对的错误。

我看过https://docs.oracle.com/javase/8/docs/api/java/net/URI.htmlURI在指定方案时是绝对的，否则它是相对的。但我认为我的URI指定了一个方案。

所以我在这里有点迷路了。有人知道我做错了什么吗？或者为什么我会出现这个错误？

我使用spring-vault-core-2.2.0.RELEASE

这是我的代码：

VaultEndpoint ep = VaultEndpoint.create(host, portInt);
if (scheme != null) {
ep.setScheme(scheme);
}
if (authMethod.equals("token")) {
vaultTemplate = new VaultTemplate(ep, new TokenAuthentication(token));
} else if (authMethod.equals("appRole")) {
RestOperations restOperations = VaultClients.createRestTemplate();
AppRoleAuthenticationOptions options = AppRoleAuthenticationOptions.builder()
.roleId(AppRoleAuthenticationOptions.RoleId.provided(roleId))
.secretId(AppRoleAuthenticationOptions.SecretId.wrapped(VaultToken.of(secretId))).build();
vaultTemplate = new VaultTemplate(ep, new AppRoleAuthentication(options, restOperations));
}
}

如果我试图获得vaultToken:，我也会遇到同样的错误

RestOperations restOperations = VaultClients.createRestTemplate();
AppRoleAuthenticationOptions options = AppRoleAuthenticationOptions.builder()
.roleId(AppRoleAuthenticationOptions.RoleId.provided(roleId))
.secretId(AppRoleAuthenticationOptions.SecretId.wrapped(VaultToken.of(uncryptedSecretId))).build();
AppRoleAuthentication appRoleAuth = new AppRoleAuthentication(options, restOperations);
VaultToken appRoleToken = appRoleAuth.login();

错误如下：

Answer 1

经过进一步调查，问题是我如何安装restTemplate。我将spring上下文库添加到我的项目中，并实现了AbstractVaultConfiguration类。这个类包含一个restOperations((函数，它解决了我的问题。

这就是我解决问题的方法：

public class AppRoleAuthenticationService extends AbstractVaultConfiguration {
private String roleId;
private String secretId;
private String host;
private String scheme;
private String port;
public AppRoleAuthenticationService(String roleId, String secretId, String host, String scheme, String port) {
this.roleId = roleId;
this.secretId = secretId;
this.host = host;
this.scheme = scheme;
this.port = port;
}
@Override
public VaultEndpoint vaultEndpoint() {
int portInt = Integer.parseInt(port);
VaultEndpoint ep = VaultEndpoint.create(host, portInt);
if (scheme != null) {
ep.setScheme(scheme);
}
return ep;
}
@Override
public ClientAuthentication clientAuthentication() {
AppRoleAuthenticationOptions options = AppRoleAuthenticationOptions.builder()
.roleId(AppRoleAuthenticationOptions.RoleId.provided(roleId))
.secretId(AppRoleAuthenticationOptions.SecretId.provided(secretId)).build();
return new AppRoleAuthentication(options, restOperations());
}

}

然后使用这个类：

AppRoleAuthenticationService appRoleAuth = new AppRoleAuthenticationService(roleId, 
uncryptedSecretId, host, scheme, port);
VaultEndpoint vaultEp = appRoleAuth.vaultEndpoint();
ClientAuthentication auth = appRoleAuth.clientAuthentication();
vaultTemplate = new VaultTemplate(vaultEp, auth);
