有没有办法仅输出原始定义的响应体中的一个字段

Question

对于上下文，我正在调查为什么One One返回从未设定的字段的空字段。以下是我的原始定义和响应主体。我使用Proto Buf定义作为在我的应用程序中传递消息的一种方式，并在订单中将DB对象转换回原始对象，我使用转换器类转换DB-＆gt;原始buf，反之亦然，

如果我明确将pcisaq saq_b设置为java生成的代码：

V1Form formObject = new V1Form();
formObject.setId("some_id");
formObject.setCreatedAt("");
formObject.setUpdatedAt("");
formObject.setSaqB("some_object");

// the response body is shown below: 

api响应

{
    "id": "xxxxxxxxx",
    "created_at": "2022-04-26T22:57:51.671825-07:00",
    "updated_at": "2022-04-26T22:57:51.671825-07:00",
    "pci_saq_a": null,
    "pci_saq_b": {
        "name": null,
        "signed_at": null,
        "user_agent": null,
        "ip_address": null,
        "is_accepted": null
    },
    "pci_saq_c": null,
}

，则预期的行为应为：

{
    "id": "xxxxxxxxx",
    "created_at": "2022-04-26T22:57:51.671825-07:00",
    "updated_at": "2022-04-26T22:57:51.671825-07:00",
    "pci_saq_b": {
        "name": null,
        "signed_at": null,
        "user_agent": null,
        "ip_address": null,
        "is_accepted": null
    },
}

proto定义：

message Form {


  string id = 1 [
    (google.api.field_behavior) = OUTPUT_ONLY,
    (grpc.gateway.protoc_gen_openapiv2.options.openapiv2_field) = {
      read_only: true,
      example: '"377eca8f-8cf4-42d4-bde6-17d44dc1e961"'
    }
  ];

    google.protobuf.Timestamp created_at = 2[
    (google.api.field_behavior) = OUTPUT_ONLY,
    (grpc.gateway.protoc_gen_openapiv2.options.openapiv2_field) = {
      read_only: true
    }
  ];

  // The time the resource will update.
  google.protobuf.Timestamp updated_at = 3[
    (google.api.field_behavior) = OUTPUT_ONLY,
    (grpc.gateway.protoc_gen_openapiv2.options.openapiv2_field) = {
      read_only: true
    }
  ];


  oneof pci_form {
    PciSaq pci_saq_a = 2;
    PciSaq pci_saq_b = 3;
    PciSaq pci_saq_c = 4;
  }

}

form.java生成的代码包含字段也是如此

  @JsonProperty("pci_saq_a")
  private V1PciSaq pciSaqA;

  @JsonProperty("pci_saq_b")
  private V1PciSaq pciSaqB;

  @JsonProperty("pci_saq_c")
  private V1PciSaq pciSaqC;

Answer 1

您是否尝试使用可选关键字？

message Form {

  // other fields ...

  optional PciSaq pci_saq_a = 2;
  optional PciSaq pci_saq_b = 3;
  optional PciSaq pci_saq_c = 4;
}

这个有关可选的问题看起来很有趣：如何在Protobuf 3中定义可选字段3
