        }
    ]
}
```

将得到如下文本内容：

```
Validation errors:
Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
```

### 覆盖 `HTTPException` 错误处理器 { #override-the-httpexception-error-handler }

同理，也可以覆盖 `HTTPException` 的处理器。

例如，只为这些错误返回纯文本响应，而不是 JSON：

     *
     * @param json the JSON string to parse.
     * @return the parsed map, or an empty map on failure.
     */
    protected Map<String, Object> parseJson(final String json) {
        try {
            return objectMapper.readValue(json, new TypeReference<Map<String, Object>>() {
            });
        } catch (final Exception e) {
            logger.warn("Failed to parse JSON.", e);
            return Map.of();

	cred := credentialHeader{
		accessKey: accessKey,
	}
	parsedDate, err := time.Parse(yyyymmdd, date)
	if err != nil {
		t.Fatalf("Failed to parse date")
	}
	cred.scope.date = parsedDate
	cred.scope.region = region
	cred.scope.service = service
	cred.scope.request = requestVersion

	return cred
}

                }
            }
        } catch (ParseException e) {
            System.err.println("Unable to parse maven.config file options: " + e.getMessage());
            cliManager.displayHelp(System.out);
            throw e;
        }

        try {
            CommandLine mavenCli = cliManager.parse(cliRequest.args);
            if (mavenConfig == null) {
                cliRequest.commandLine = mavenCli;

        state == STATE_WRITING_REQUEST_BODY ||
        state == STATE_READ_RESPONSE_HEADERS,
    ) {

    }

        } catch (final IllegalArgumentException e) {
            log.error("Failed to parse OID", e);

경로 매개변수 `item_id`가 `int`가 아닌 `"foo"` 값을 가졌기 때문입니다.
