"type": "type_error.integer"
        }
    ]
}
```

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：

    sslSocket: SSLSocket,
  ): ConnectPlan {
    if (connectionSpecIndex != -1) return this
    return nextConnectionSpec(connectionSpecs, sslSocket)
      ?: throw UnknownServiceException(
        "Unable to find acceptable protocols." +
          " isFallback=$isTlsFallback," +
          " modes=$connectionSpecs," +
          " supported protocols=${sslSocket.enabledProtocols!!.contentToString()}",
      )
  }

                if (!allowUserInteraction || (attempt >= MAX_REDIRECTS)) {
                    break;
                }
                reconnect();
            }
            throw new IOException("Unable to negotiate NTLM authentication.");
        } finally {
            cachedOutput = null;
        }
    }

    private NtlmMessage attemptNegotiation(final int response) throws IOException {

            "type": "type_error.integer"
        }
    ]
}
```

obtendrás una versión en texto, con:

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

### Sobrescribir el manejador de errores de `HTTPException` { #override-the-httpexception-error-handler }

De la misma manera, puedes sobrescribir el manejador de `HTTPException`.

```JSON
{
  "detail": [
    {
      "type": "int_parsing",
      "loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }
  ]
}
```

porque el parámetro de path `item_id` tenía un valor de `"foo"`, que no es un `int`.

```JSON
{
  "detail": [
    {
      "type": "int_parsing",
      "loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }
  ]
}
```

because the path parameter `item_id` had a value of `"foo"`, which is not an `int`.

            "type": "type_error.integer"
        }
    ]
}
```

você receberá a versão em texto:

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

### Sobrescreva o manipulador de erro `HTTPException` { #override-the-httpexception-error-handler }

Do mesmo modo, você pode sobrescrever o `HTTPException`.

			w.WriteHeader(http.StatusForbidden)
			return
		}
		conn, _, _, err := ws.UpgradeHTTP(req, w)
		if err != nil {
			if debugPrint {
				fmt.Printf("grid: Unable to upgrade: %v. http.ResponseWriter is type %T\n", err, w)
			}
			w.WriteHeader(http.StatusUpgradeRequired)
			return
		}
		m.IncomingConn(ctx, conn)
	}
}

            List<String> versionLines = IOUtils.readLines(new FileInputStream(versionsFile), "UTF-8");
            return new BwcVersions(versionLines);
        } catch (IOException e) {
            throw new IllegalStateException("Unable to resolve to resolve bwc versions from versionsFile.", e);
        }
    }

    private void logGlobalBuildInfo() {
        final String osName = System.getProperty("os.name");

        else

        fi

      --yjp)
        if [ ! -f "$YJPLIB" ]; then
          echo "Error: Unable to autodetect the YJP library location. Please set YJPLIB variable" >&2
          exit 1
        fi
        MAVEN_OPTS="-agentpath:$YJPLIB=onexit=snapshot,onexit=memory,tracing,onlylocal $MAVEN_OPTS"
