/// info | 信息

要使用 `EmailStr`，首先安装 [`email-validator`](https://github.com/JoshData/python-email-validator)。

请先创建并激活一个[虚拟环境](../virtual-environments.md)，然后安装，例如：

```console
$ pip install email-validator
```

或者：

```console
$ pip install "pydantic[email]"
```

///

我们使用这个模型来声明输入，同时也用相同的模型来声明输出：

	id := mustGetRequestID(UTCNow())

	if len(id) != 16 {
		t.Fail()
	}

	var e rune
	for _, char := range id {
		e = char

		// Ensure that it is alphanumeric, in this case, between 0-9 and A-Z.
		isAlnum := ('0' <= e && e <= '9') || ('A' <= e && e <= 'Z')
		if !isAlnum {
			t.Fail()
		}
	}

        ComponentUtil.getLogNotificationHelper()
                .offer(new LogNotificationEvent(System.currentTimeMillis(), "WARN", "org.test", "msg2", null));

        // expired() will drain buffer then fail on OpenSearch (not available) but should not throw
        logNotificationTarget.expired();

        // Buffer should be empty after expired() drained it

  }

  private void assertBad(String spec) {
    try {
      HostSpecifier.fromValid(spec);
      fail("Should have thrown IllegalArgumentException: " + spec);
    } catch (IllegalArgumentException expected) {
    }

    try {
      HostSpecifier.from(spec);
      fail("Should have thrown ParseException: " + spec);
    } catch (ParseException expected) {

			t.Errorf("Test %d: %s: Expected to fail with error \"%s\", but passed instead.", i, instanceType, testCase.expectedError.Error())
			continue
		}
		// Failed as expected, but does it fail for the expected reason.
		if actualErr != nil && actualErr != testCase.expectedError {

                .orElse(false);
    }

例えば、クライアントが次のフォームフィールドを送ろうとした場合:

- `username`: `Rick`
- `password`: `Portal Gun`
- `extra`: `Mr. Poopybutthole`

フィールド `extra` は許可されていない旨のエラーレスポンスが返されます:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
}
```

```
org.gradle[.<qualifier>].<feature-name>.<detail>
```

The optional qualifier defines the secondary aspects, if any.

For better ergonomics on the CLI, some properties can have supplementary command-line build option(s).
The name of the feature in the build option SHOULD be the same as in the property name.

Shared scheme for long-form build options:

```
--<feature-name>-<detail>
```

                        "type": "object",
