**Key Fields**: `crawlerContext`, `urlFilter`, `intervalController`, `clientFactory`, `ruleManager`

### CrawlerContext (`CrawlerContext.java`)

Execution context and configuration.

**Important Fields**:
```java
String sessionId                // Format: yyyyMMddHHmmssSSS
volatile CrawlerStatus status   // DONE, RUNNING

    }

    @Test
    @DisplayName("seq ctor: tag 3 with wrong tag class is rejected")
    void sequenceConstructor_ticketTag_wrongClass_throws() {
        // Arrange: minimal valid fields + tag 3 as CONTEXT-SPECIFIC instead of APPLICATION
        ASN1EncodableVector v = new ASN1EncodableVector();
        v.add(new DERTaggedObject(true, 0, new ASN1Integer(Integer.parseInt(KerberosConstants.KERBEROS_VERSION))));

				if dataType != jsonparser.String {
					return errors.New("sub: Expected string")
				}
				c.Subject, err = jsonparser.ParseString(value)
				return err
			}
		}
		// Ignore unknown fields
		return nil
	})
}

// MapClaims - implements custom unmarshaller
type MapClaims struct {
	AccessKey string `json:"accessKey,omitempty"`
	jwtgo.MapClaims
}

比如，你可以将请求体的一个 `example` 传递给 `Body`:

{* ../../docs_src/schema_extra_example/tutorial003_an_py310.py hl[22:27] *}

## 文档 UI 中的例子

使用上面的任何方法，它在 `/docs` 中看起来都是这样的:
