针对 swagger 文件验证 json 有效负载 - json-schema-validator

Validating json payload against swagger file - json-schema-validator(针对 swagger 文件验证 json 有效负载 - json-schema-validator)

问题描述

我正在尝试针对包含服务协议的 swagger 文件验证 json 有效负载.我正在使用 json-schema-validator(2.1.7) 库来实现这一点，但目前它没有针对指定的模式或最小/最大长度进行验证.

I am trying to validate a json payload against a swagger file that contains the service agreement. I am using the json-schema-validator(2.1.7) library to achieve this, but at the moment it's not validating against the specified patterns or min/max length.

Java 代码:

public void validateJsonData(final String jsonData) throws IOException, ProcessingException {

    ClassLoader classLoader = getClass().getClassLoader();
    File jsonSchemaFile = new File (classLoader.getResource("coachingStatusUpdate.json").getFile());

    String jsonSchema = new String(Files.readAllBytes(jsonSchemaFile.toPath()));

    final JsonNode dataNode = JsonLoader.fromString(jsonData);
    final JsonNode schemaNode = JsonLoader.fromString(jsonSchema);

    final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
    JsonValidator jsonValidator = factory.getValidator();

    ProcessingReport report = jsonValidator.validate(schemaNode, dataNode);
    System.out.println(report);
    if (!report.toString().contains("success")) {
        throw new ProcessingException (
                report.toString());
    }
}

  }

如您所见，我通过 -1 的相关 ID 发送，这应该验证失败，但目前返回成功:

As you can see I am sending through a correlationID of -1, which should fail validation, but at the moment is's returning as successful:

com.github.fge.jsonschema.report.ListProcessingReport: success

推荐答案

我建议使用这个库，它对我有用:

I suggest using this library, which worked for me:

https://github.com/bjansen/swagger-schema-validator

例子:

invalid-pet.json

invalid-pet.json

{
  "id": 0,
  "category": {
    "id": 0,
    "name": "string"
  },
  "named": "doggie",
  "photoUrls": [
    "string"
  ],
  "tags": [
    {
      "id": 0,
      "name": "string"
    }
  ],
  "status": "available"
}

我的 SchemaParser:

My SchemaParser:

@Component
public class SchemaParser {

    private Logger logger = LoggerFactory.getLogger(getClass());

    public boolean isValid(String message, Resource schemaLocation) {

        try (InputStream inputStream = schemaLocation.getInputStream()) {
            SwaggerValidator validator = SwaggerValidator.forJsonSchema(new InputStreamReader(inputStream));
            ProcessingReport report = validator.validate(message, "/definitions/Pet");
            return report.isSuccess();
        } catch (IOException e) {
            logger.error("IOException", e);
            return false;
        } catch (ProcessingException e) {
            e.printStackTrace();
            return false;
        }
    }
}

测试:

    @Test
    void shouldFailValidateWithPetstoreSchema() throws IOException {

        final Resource validPetJson = drl.getResource("http://petstore.swagger.io/v2/swagger.json");

        try (Reader reader = new InputStreamReader(validPetJson.getInputStream(), UTF_8)) {
            final String petJson = FileCopyUtils.copyToString(reader);
            final boolean valid = schemaParser.isValid(petJson, petstoreSchemaResource);
            assertFalse(valid);
        }
    }
