Daha kapsamlı bir örneğe bakalım.

本章添加上一章示例中欠缺的部分，实现完整的安全流。

## 获取 `username` 和 `password` { #get-the-username-and-password }

首先，使用 **FastAPI** 安全工具获取 `username` 和 `password`。

OAuth2 规范要求使用“密码流”时，客户端或用户必须以表单数据形式发送 `username` 和 `password` 字段。

并且，这两个字段必须命名为 `username` 和 `password`，不能使用 `user-name` 或 `email` 等其它名称。

不过也不用担心，前端仍可以显示终端用户所需的名称。

数据库模型也可以使用所需的名称。

但对于登录*路径操作*，则要使用兼容规范的 `username` 和 `password`，（例如，实现与 API 文档集成）。

    /**
     * Create username/password credentials with specified domain
     *
     * @param domain the authentication domain
     * @param username the username
     * @param passwordHash
     *            NT password hash
     */
    public NtlmNtHashAuthenticator(final String domain, final String username, final byte[] passwordHash) {
        super(domain, username, (String) null, AuthenticationType.USER);

    }

    private String maskUsername(String username) {
        if (!maskSensitiveData || username == null) {
            return username;
        }

        // Show first and last character only
        if (username.length() <= 2) {
            return "***";
        }

        return username.charAt(0) + "***" + username.charAt(username.length() - 1);
    }

     *
     * @param form the form containing duplicate host data
     * @param username the current username
     * @param currentTime the current timestamp
     * @return optional duplicate host entity
     */
    public static OptionalEntity<DuplicateHost> getEntity(final CreateForm form, final String username, final long currentTime) {
        switch (form.crudMode) {
        case CrudMode.CREATE:

	conn, err := l.LDAP.Connect()
	if err != nil {
		return nil, err
	}
	defer conn.Close()

	// Bind to the lookup user account
	if err = l.LDAP.LookupBind(conn); err != nil {
		return nil, err
	}

	// Check if the passed in username is a valid DN.
	if !l.ParsesAsDN(username) {
		// We consider it as a login username and attempt to check it exists in
		// the directory.
