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

你將會改而得到文字版：

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

### 覆寫 `HTTPException` 的錯誤處理器 { #override-the-httpexception-error-handler }

同樣地，你也可以覆寫 `HTTPException` 的處理器。

例如，你可能想在這些錯誤時回傳純文字而非 JSON：

        try {
            stopwordsFile.reload(null, failingStream);
            fail("Should throw DictionaryException");
        } catch (DictionaryException e) {
            assertTrue(e.getMessage().contains("Failed to parse"));
        }
    }

    // Test update with InputStream
    @Test
    public void test_update_withInputStream() throws IOException {
        String content = "new1\n" + "new2\n" + "new3\n";

                sub.include("**/*.adoc");
                // Flatten adocs into a single directory
                sub.eachFile(fcd -> fcd.setRelativePath(RelativePath.parse(true, fcd.getName())));
            });

            // From the snippets, filter out files generated if the build contained was ever executed
            task.from(extension.getUserManual().getSnippets(), sub -> {

			accessKey:          credentials.AccessKey,
			secretKey:          credentials.SecretKey,
			expectedRespStatus: http.StatusLengthRequired,
		},
		// Test case - 4.
		// setting the readSeeker to `nil`, bucket policy parser will fail.
		{
			bucketName:         bucketName,
			bucketPolicyReader: nil,

			policyLen:          10,
			accessKey:          credentials.AccessKey,
			secretKey:          credentials.SecretKey,

        writeTestFile("invalid => "); // Invalid format

        try {
            charMappingFile.reload(null);
            // If no exception, the file might have been parsed with warnings
            assertTrue(true);
        } catch (Exception e) {
            // Expected for invalid format
            assertTrue(true);
        }
    }

	signature := hex.EncodeToString(sumHMAC(signingKey, []byte(stringToSign)))

	// final Authorization header
	parts := []string{
		"AWS4-HMAC-SHA256" + " Credential=" + accessKey + SlashSeparator + scope,
		"SignedHeaders=" + signedHeaders,
		"Signature=" + signature,
	}
	auth := strings.Join(parts, ", ")
	req.Header.Set("Authorization", auth)

	return signature, nil
}

// Returns new HTTP request object.

        // Will fail due to null user, but verifies depth check passes
        try {
            authenticator.getParentGroup(null, "test-id", 4);
            // If we reach here without NullPointerException, depth check passed
        } catch (NullPointerException e) {
            // Expected due to null user - depth check passed, processing attempted
            assertTrue(true);
        } catch (Exception e) {

      @Nullable Object firstParam, ImmutableList<Class<?>> sig) {
    Object[] params = new Object[sig.size()];

        for (int i = 2; i < params.length; i++) {

      }
    }

    Object[] params = new Object[sig.size()];
    params[0] = firstParam;
    if (params.length > 1) {
      params[1] = "";
      if (params.length > 2) {
        // fill in the rest of the array with arbitrary instances
        for (int i = 2; i < params.length; i++) {
          params[i] = ArbitraryInstances.get(sig.get(i));
        }
      }
    }

                    }
                }
            }
            return null;
        } catch (final Exception e) {
            throw new CrawlingAccessException("Failed to parse " + url, e);
