json中的多部分文件和嵌套对象来测试POSTMAN中的post请求？

Question

想在POSTMAN中测试post请求。

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 {  
   ...
}

我想送SchoolDto（邮递员：尸体-

请帮忙。

Answer 1

当我使用多部分/表单数据时，我使用的是Spring Boot 2.0。x、 Java 8和使用相同方法=POST

您需要正确实施以下几点。也许这可以帮助您：

@RequestMapping(value = MEUVOUCHER_FILE, method = POST, consumes =  "multipart/form-data", produces = APPLICATION_JSON_UTF8_VALUE)
@ResponseStatus(code = CREATED)
public ObjectResponse<MEUVOUCHERFileRetrievalDto> createMEUVOUCHERFile(
    @RequestPart("MEUVOUCHERFile") MultipartFile MEUVOUCHERFile,
    @ApiParam(name = "metadata", value = "{ \"MEUVOUCHERTypeId\" : 0, \"relatedContentId\" : 0, \"expireDate\" : \"datetime\" }", required = true)
    

Answer 2

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/form-data请求。您的请求可能有三个部分proileImage、GalleryImages和School Info。

从SchoolDto类中删除proileImage和GalleryImages

修改方法签名以支持多部分请求

@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，您还可以使用RestDocumentationExpress实现@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，以帮助您了解如何向您的endpoint发出请求
