我试图从邮递员那里访问keycloak API.但它显示了400个不良请求.

我用以下格式打电话给api.

http://{hostname}:8080/auth/realms/master/protocol/openid-connect/token?username=admin&password=admin&client_id=admin-cli&grant_type=password

在我设置的标题中 content_type as application/x-www-form-urlencoded

我得到的答复如下.

{
    "error": "invalid_request",
    "error_description": "Missing form parameter: grant_type"
}

任何人都可以帮助我.任何帮助将不胜感激.提前致谢

我正在尝试以编程方式在 keycloak 中访问创建用户。但是我收到 403 作为状态代码。我正在关注以下链接。

谁能帮我？提前致谢

我使用以下代码创建用户

Keycloak kc = Keycloak.getInstance(
                     "http://{server name}:8080/auth",
                     "{realm name}", // the realm to log in to
                     "{useraname}", 
                     "{password}",  // the user
                     "{client id}",
                     "{client secret key}");

            CredentialRepresentation credential = new CredentialRepresentation();
            credential.setType(CredentialRepresentation.PASSWORD);
            credential.setValue("test123");
            UserRepresentation user = new UserRepresentation();
            user.setUsername("codeuser");
            user.setFirstName("sampleuser1");
            user.setLastName("password");

            user.setCredentials(Arrays.asList(credential));
            user.setEnabled(true);
            Response result = kc.realm("{realm name}").users().create(user);

response.status 是 403

如何使用 Java 应用程序在 keycloak 中以编程方式创建客户端？

在我的spring starter项目中,我正在尝试使用JPA进行API调用.我pom.xml看起来像这样:

当我尝试运行它时会出现错误

java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/Module

我为此搜索了很多.但找不到确切的解决方案.请任何人帮我解决这个问题.提前致谢.
