json中的MultipartFile和嵌套对象来测试POSTMAN中的post请求? [英] MultipartFile and nested object in a json to test post request in POSTMAN?

问题描述

想在 POSTMAN 中测试一个 post 请求.

Wanted to test a post request in POSTMAN.

public enum TimeUnit {

    HOURS("hours"),
    MINUTE("mins");

    private String value;

    public static TimeUnit get(String text) {
        return Arrays.stream(TimeUnit.values())
                     .filter(a -> Objects.equals(a.getValue(), text))
                     .findFirst()
                     .orElse(null);
    }
}

public final class SchoolTimeTable {

  private Double value;
  private TimeUnit unit;
 
  public SchoolTimeTable (double value, TimeUnit unit) {
      this.value = value;
      this.unit=unit;
  }
}

public class SchoolDto {
    private String name;
    private String address;
    private MultipartFile profileImage;
    private MultipartFile[] galleryImages;
    private SchoolTimeTable openCloseTime;
 }

Spring MVC 控制器

@PostMapping(value = "/schoolInfo", produces = { MediaType.APPLICATION_JSON_VALUE }) 
public ResponseEntity<Object> saveSchoolInfo( @Parameter(required = true, schema = @Schema(implementation = SchoolDto.class)) SchoolDto schoolDto) throws IOException, InterruptedException {  
   ...
}

我想在发布请求中发送 SchoolDto(邮递员:body->raw->json)以获得所需的结果.但我无法创建支持 SchoolTimeTable (Object) 和 MultipartFile 类型的 json.我什至不知道是否可以使用 JSON.注意:使用带有键/值的 body->form-data 也可以实现相同的效果.

I want to send SchoolDto (POSTMAN: body->raw->json) in post request to get desired result. But I am not able to create the json which supports SchoolTimeTable (Object) and MultipartFile types. I don't even know whether it is possible with JSON or not. Note: Same could be achieved using body->form-data with key/value.

请帮忙.

推荐答案

我认为您不应该在 application/json 请求中上传文件，为此您应该使用 multipart/表单数据 请求.您的请求可能包含三部分 profileImage、galleryImages 和 schoolInfo.

I think you should not upload files within a application/json request, to do so you should use a multipart/form-data request. Your request may have three parts profileImage, galleryImages and schoolInfo.

从SchoolDto类

修改你的方法签名以支持多部分请求

Modify your method signature to support the multipart request

@PostMapping(value = "/schoolInfo", consumes = MediaType.MULTIPART_FORM_DATA_VALUE) 
public ResponseEntity<Object> saveSchoolInfo(@RequestPart(value = "profileImage") MultipartFile profileImage, @RequestPart(value = "galleryImages") MultipartFile[] galleryImages, @RequestPart(value = "schoolInfo") SchoolDto schoolInfo) throws IOException, InterruptedException {  
   ...
}

此外，您可以使用 RestDocumentationExtension 实施 @SpringBootTest 单元测试，以检查您的代码是否有效并生成一个 curl 请求示例将帮助您了解如何向您的端点发出请求

In addtion you can implement a @SpringBootTest unit test using RestDocumentationExtension to check whether your code works and to produce a curl request sample that will help you to understand how to make a request to your endpoint
