Google Form API - Error when Create, Update Item

问题

我尝试使用Google表单API更新我的现有表单。我在请求中填写了位置字段，但仍然收到服务器的错误消息create_item.location.index is invalid or was not provided。

创建请求代码

  1. func UpdateForm(formId string, form *forms.Form) *forms.Form {
  2.    var requestElements []*forms.Request
  3.    // 更新表单信息
  4.    requestElements = append(requestElements, &forms.Request{
  5.       UpdateFormInfo: &forms.UpdateFormInfoRequest{
  6.          Info:       form.Info,
  7.          UpdateMask: "*",
  8.       },
  9.    })
  10.    // 添加项目
  11.    for i, item := range form.Items {
  12.       element := &forms.Request{
  13.          CreateItem: &forms.CreateItemRequest{
  14.             Item:     item,
  15.             Location: &forms.Location{Index: int64(i)},
  16.          },
  17.       }
  18.       requestElements = append(requestElements, element)
  19.    }
  21.    request := forms.BatchUpdateFormRequest{
  22.       IncludeFormInResponse: true,
  23.       Requests:              requestElements,
  24.    }
  26.    response, err := formService.Forms.
  27.       BatchUpdate(formId, &request).
  28.       Context(context.TODO()).
  29.       Do()
  30.    if err != nil {
  31.       panic(err)
  32.    }
  34.    return response.Form
  35. }

注意：我正在使用form api v1。

I try to update my existing form using google form API. I filled location field in request but still received error message from server create_item.location.index is invalid or was not provided

Create Request Code

  1. func UpdateForm(formId string, form *forms.Form) *forms.Form {
  2.    var requestElements []*forms.Request
  3.    // Update form info
  4.    requestElements = append(requestElements, &forms.Request{
  5.       UpdateFormInfo: &forms.UpdateFormInfoRequest{
  6.          Info:       form.Info,
  7.          UpdateMask: "*",
  8.       },
  9.    })
  10.    // Add items
  11.    for i, item := range form.Items {
  12.       element := &forms.Request{
  13.          CreateItem: &forms.CreateItemRequest{
  14.             Item:     item,
  15.             Location: &forms.Location{Index: int64(i)},
  16.          },
  17.       }
  18.       requestElements = append(requestElements, element)
  19.    }
  21.    request := forms.BatchUpdateFormRequest{
  22.       IncludeFormInResponse: true,
  23.       Requests:              requestElements,
  24.    }
  26.    response, err := formService.Forms.
  27.       BatchUpdate(formId, &request).
  28.       Context(context.TODO()).
  29.       Do()
  30.    if err != nil {
  31.       panic(err)
  32.    }
  34.    return response.Form
  35. }

Note: I'm using form api v1

答案1

得分: 0

最后我找到了问题所在。当向表单中添加新项时，我们必须从索引0开始，但是在protobuf中，0是int的默认值，所以当请求发送时会被忽略。
解决方案：强制发送字段Index

  1. // 添加项
  2. for i, item := range form.Items {
  3. 	element := &forms.Request{
  4. 		CreateItem: &forms.CreateItemRequest{
  5. 			Item: item,
  6. 			Location: &forms.Location{
  7. 				Index:           int64(i),
  8. 				ForceSendFields: []string{"Index"},
  9. 			},
  10. 		},
  11. 	}
  12. 	requestElements = append(requestElements, element)
  13. }
英文:

Finally i found the issue. When add a new item into form we must start with index 0, but 0 is default value of int in protobuf so it will be ignore when request send.
Solution: Force send field Index

  1. // Add items
  2. for i, item := range form.Items {
  3. 	element := &forms.Request{
  4. 		CreateItem: &forms.CreateItemRequest{
  5. 			Item: item,
  6. 			Location: &forms.Location{
  7. 				Index:           int64(i),
  8. 				ForceSendFields: []string{"Index"},
  9. 			},
  10. 		},
  11. 	}
  12. 	requestElements = append(requestElements, element)
  13. }
