java-XMPPError：错误请求-修改错误,使用smack库4.1.8和openfire创建新用户

我一直在使用smack客户端库4.1.8和xmpp服务器(openfire服务器)开发聊天应用程序,但是在尝试使用Accountmanger类创建新用户时,它引发了异常“ XMPPError：bad-request-Modify”

XMPPTCPConnectionConfiguration conf = XMPPTCPConnectionConfiguration.builder()
                        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                        .setHost("127.0.0.1")
                        .setDebuggerEnabled(true)
                        .setPort(5222)
                        .setSendPresence(true)
                        .setServiceName("127.0.0.1")
                        .build();

                AbstractXMPPConnection conn2 = new XMPPTCPConnection(conf);

                //conn2.login();
                conn2.connect();

                AccountManager accountManager = AccountManager.getInstance(conn2);
                if (accountManager.supportsAccountCreation()) {
                    accountManager.sensitiveOperationOverInsecureConnection(true);
                    accountManager.createAccount("qidus", "123456");
                    conn2.login("qidus", "123456");

                }

            } catch (SmackException | IOException | XMPPException e) {
                e.printStackTrace();
            }

唯一的例外是

解决方法:

您需要正确设置服务名称.您可以通过管理面板(127.0.0.1:9090)在Openfire中检查服务名称,该名称位于页面中间的第一页,登录后查找“服务器名称”.

默认情况下,这是您的计算机名称.

但是,您的代码将仅运行一次：第二次AccountManger将由于已注册用户而引发异常.
