How to upload CSV file as a post request in Karate 0.9.0 version?

我在 Controller 中有一个文件上传端点(/document)，定义如下:

@RestController
public class FileUploadController {

    @Autowired
    private PersonCSVReaderService personCSVReaderService;

    @PostMapping(value = "/document", consumes= {MediaType.MULTIPART_FORM_DATA_VALUE})
    public void handleFileUpload3(@RequestPart("file") MultipartFile file, @RequestPart("metadata") DocumentMetadata metadata) {
        System.out.println(String.format("uploading file %s of %s bytes", file.getOriginalFilename(), file.getSize()));
        personCSVReaderService.readPersonCSV(file, metadata);
    }
}

我可以使用 Advanced Rest Client (ARC) 或 Postman 测试此端点，方法是定义引用 people.csv 文件的"file"部分和指定一些示例元数据 JSON 的文本部分。



一切正常，我得到了一个 200 状态，people.csv 文件内容被服务方法写入控制台输出:

uploading file people.csv of 256 bytes
{Address=1, City=2, Date of Birth=6, Name=0, Phone Number=5, State=3, Zipcode=4}
Person{name='John Brown', address='123 Main St.', city='Scottsdale', state='AZ', zipcode='85259', phoneNumber='555-1212', dateOfBirth='1965-01-01'}
Person{name='Jan Black', address='456 University Dr.', city='Atlanta', state='GA', zipcode='30306', phoneNumber='800-1111', dateOfBirth='1971-02-02'}
Person{name='Mary White', address='789 Possum Rd.', city='Nashville', state='TN', zipcode='37204', phoneNumber='888-2222', dateOfBirth='1980-03-03'}

现在，我想将此作为自动 Karate 测试运行。我已经指定了一个 MockConfig :

@Configuration
@EnableAutoConfiguration
@PropertySource("classpath:application.properties")
public class MockConfig {

    // Services ...
    @Bean
    public PersonCSVReaderService personCSVReaderService() {
        return new PersonCSVReaderService();
    }

    // Controllers ...
    @Bean
    public FileUploadController fileUploadController() {
        return new FileUploadController();
    }
}

我在类路径中还有一个 MockSpringMvcServlet ，我的 karate-config.js 是:

function fn() {    
   var env = karate.env; // get system property 'karate.env'
   if (!env) {
      env = 'dev';
   }
   karate.log('karate.env system property was:', env);

   var config = {
     env: env,
     myVarName: 'someValue',
     baseUrl: 'http://localhost:8080'
   }

   if (env == 'dev') {
      var Factory = Java.type('MockSpringMvcServlet');
      karate.configure('httpClientInstance', Factory.getMock());
      //var result = karate.callSingle('classpath:demo/headers/common-noheaders.feature', config);
   } else if (env == 'stg') {
      // customize
   } else if (env == 'prod') {
      // customize
   }

   return config;
}

其他 Karate 测试使用模拟 servlet 运行正常。

但是，当我尝试此测试来测试/document 端点时:

Feature: file upload end-point

  Background:
    * url baseUrl
    * configure lowerCaseResponseHeaders = true

  Scenario: upload file
    Given path '/document'
    And header Content-Type = 'multipart/form-data'
    And multipart file file =  { read: 'people.csv', filename: 'people.csv', contentType: 'text/csv' }
    And multipart field metadata = { name: "joe", description: "stuff" }
    When method post
    Then status 200

我收到此错误:

我只能假设参数不符合我的端点所期望的 - 我从未在 Debug模式下进入端点。

我试过这个:

    And multipart file file =  read('people.csv')
    And multipart field metadata = { name: "joe", description: "stuff" }

但这也不是首发。

我究竟做错了什么？ people.csv 与 fileupload.feature 位于同一文件夹中，所以我假设它正在查找文件。我还查看了此处给出的 Karate 演示项目中的 upload.feature 文件:

Karate demo project upload.feature

但我无法让它发挥作用。任何帮助表示赞赏。提前致谢。

Postman 请求如下所示:


编辑更新:

我无法获得建议的工作答案。

这是特征文件:

Feature: file upload

  Background:
    * url baseUrl
    * configure lowerCaseResponseHeaders = true

  Scenario: upload file
    Given path '/document'
    And header Content-Type = 'multipart/form-data'
    * def temp = karate.readAsString('people.csv')
    * print temp
    And multipart file file =  { value: '#(temp)', filename: 'people.csv', contentType: 'text/csv' }
    And multipart field metadata = { value: {name: 'joe', description: 'stuff'}, contentType: 'application/json' }
    When method post
    Then status 200

这是运行该测试的控制台输出:

注意:people.csv 文件读取成功并在控制台打印。

引用文档的这一部分:https://github.com/intuit/karate#read-file-as-string

所以做这个改变:

* def temp = karate.readAsString('people.csv')
And multipart file file =  { value: '#(temp)', filename: 'people.csv', contentType: 'text/csv' }

编辑:我不好，也引用: https://github.com/intuit/karate#multipart-file
