How to copy one struct to nested struct having same fields

问题

我需要使用golang自动创建故事JIRA。为此，我可以将所需的嵌套JSON映射到golang，并且我能够创建故事。现在，我想尝试使用简单的JSON输入，并将其复制到具有相同字段的嵌套结构中。

例如，
我有以下输入JSON：

  1. {
  2.   "project": "cdo",
  3.   "summary": "sample test story",
  4.   "issueType": "Story",
  5.   "userStory" : "this is jira",
  6.   "assignee": "pradnya.shinde",
  7.   "teamOwner" : "TEAM-59",
  8.   "productOwner": "alex.anguiano"
  9. }

我已经将上述JSON映射到golang结构中，如下所示：

  1. type InputJson struct {
  2. 	Project      string `json:"project"`
  3. 	Summary      string `json:"summary"`
  4. 	Issuetype    string `json:"issueType"`
  5. 	UserStory    string `json:"userStory"`
  6. 	Assignee     string `json:"assignee"`
  7. 	TeamOwner    string `json:"teamOwner"`
  8. 	ProductOwner string `json:"productOwner"`
  9. }

我想将此结构复制到另一个嵌套结构中。
嵌套结构如下所示：

  1. type JiraCreateStory struct {
  2. 	Fields struct {
  3. 		Project struct {
  4. 			Key string
  5. 		}
  6. 		Summary   string
  7. 		Issuetype struct {
  8. 			Name string
  9. 		}
  10. 		UserStory string
  11. 		Assignee  struct {
  12. 			Name string
  13. 		}
  14. 		ProductOwner struct {
  15. 			Name string
  16. 		}
  17. 		TeamOwner string
  18. 	}
  19. }

有人可以建议我如何用简单的代码进行复制吗？

I need to automate creation of story JIRA using golang. For this I can mapped required nested json to golang and I am able to create story also. Now I want to try with simple input as json and copy to nested struct having same fields.

Ex.
I have input json like

  1. {
  2.   "project": "cdo",
  3.   "summary": "sample test story",
  4.   "issueType": "Story",
  5.   "userStory" : "this is jira",
  6.   "assignee": "pradnya.shinde",
  7.   "teamOwner" : "TEAM-59",
  8.   "productOwner": "alex.anguiano"
  9. }

I have mapped above json in golang struct like

  1. type InputJson struct {
  2. 	Project      string `json:"project"`
  3. 	Summary      string `json:"summary"`
  4. 	Issuetype    string `json:"issueType"`
  5. 	UserStory    string `json:"userStory"`
  6. 	Assignee     string `json:"assignee"`
  7. 	TeamOwner    string `json:"teamOwner"`
  8. 	ProductOwner string `json:"productOwner"`
  9. }

I want to copy this struct to another nested struct.
Nested struct is like

  1. type JiraCreateStory struct {
  2. 	Fields struct {
  3. 		Project struct {
  4. 			Key string
  5. 		}
  6. 		Summary   string
  7. 		Issuetype struct {
  8. 			Name string
  9. 		}
  10. 		UserStory string
  11. 		Assignee  struct {
  12. 			Name string
  13. 		}
  14. 		ProductOwner struct {
  15. 			Name string
  16. 		}
  17. 		TeamOwner string
  18. 	}
  19. }

Can anyone suggest how can I copy it with simple code?

声明所有结构体的类型：

  1. type JiraCreateStory struct {
  2. 	Fields Fields
  3. }
  5. type Fields struct {
  6. 	Project      Project
  7. 	Summary      string
  8. 	Issuetype    Issuetype
  9. 	UserStory    string
  10. 	Assignee     Assignee
  11. 	ProductOwner ProductOwner
  12. }
  14. type Project struct {
  15. 	Key string
  16. }
  18. type Issuetype struct {
  19. 	Name string
  20. }
  22. type Assignee struct {
  23. 	Name string
  24. }
  26. type ProductOwner struct {
  27. 	Name string
  28. }

使用复合字面量创建一个JiraCreateStory：

  1. x := JiraCreateStory{Fields: Fields{
  2. 	Project:      Project{Key: src.Project},
  3. 	Summary:      src.Summary,
  4. 	Issuetype:    Issuetype{Name: src.Issuetype},
  5. 	UserStory:    src.UserStory,
  6. 	Assignee:     Assignee{Name: src.Assignee},
  7. 	ProductOwner: ProductOwner{Name: src.ProductOwner},
  8. }}
英文:

Declare types for all structs:

  1. type JiraCreateStory struct {
  2. 	Fields Fields
  3. }
  5. type Fields struct {
  6. 	Project      Project
  7. 	Summary      string
  8. 	Issuetype    Issuetype
  9. 	UserStory    string
  10. 	Assignee     Assignee
  11. 	ProductOwner ProductOwner
  12. }
  14. type Project struct { Key string }
  15. type Issuetype struct { Name string }
  16. type Assignee struct { Name string }
  17. type ProductOwner struct { Name string }

Create a JiraCreateStory using a composite literal:

  1. x := JiraCreateStory{Fields: Fields{
  2. 	Project:      Project{Key: src.Project},
  3. 	Summary:      src.Summary,
  4. 	Issuetype:    Issuetype{Name: src.Issuetype},
  5. 	UserStory:    src.UserStory,
  6. 	Assignee:     Assignee{Name: src.Assignee},
  7. 	ProductOwner: ProductOwner{Name: src.ProductOwner},
  8. }}
