### Das Passwort überprüfen { #check-the-password }

Zu diesem Zeitpunkt liegen uns die Benutzerdaten aus unserer Datenbank vor, das Passwort haben wir jedoch noch nicht überprüft.

Lassen Sie uns diese Daten zunächst in das Pydantic-Modell `UserInDB` einfügen.

            repo = versions.latestRepository;
        }
        if (version != null && !isCompatible(request, version)) {
            logger.info(
                    "Latest version of plugin {}:{} failed compatibility check",
                    request.getGroupId(),
                    request.getArtifactId());
            versions.versions.remove(version);
            version = null;
            searchPerformed = true;
        }

        // of DefaultModelBuilder.getCache() are affected by MNG-6530

        FileUtils.copyDirectoryStructure(new File("src/test/resources/projects/grandchild-check"), tempDir.toFile());

        MavenSession mavenSession = createMavenSession(null);
        mavenSession.getRequest().setRootDirectory(tempDir);

common_parameters(["common_parameters"])
read_items["/items/"]
read_users["/users/"]

common_parameters --> read_items
common_parameters --> read_users
```

这样，只编写一次代码，**FastAPI** 就可以为多个*路径操作*共享这段代码 。

/// check | 检查

注意，无需创建专门的类，并将之传递给 **FastAPI** 以进行「注册」或执行类似的操作。

只要把它传递给 `Depends`，**FastAPI** 就知道该如何执行后续操作。

///

## 要不要使用 `async`？

**FastAPI** 调用依赖项的方式与*路径操作函数*一样，因此，定义依赖项函数，也要应用与路径操作函数相同的规则。

### Revisa el password { #check-the-password }

En este punto tenemos los datos del usuario de nuestra base de datos, pero no hemos revisado el password.

Primero pongamos esos datos en el modelo `UserInDB` de Pydantic.
