英文:
Parse JSON into nested structs
问题
以下是翻译好的内容：
type APIResponse struct {
Results []Result `json:"results,omitempty"`
Paging Paging
}
type Result struct {
Id string `json:"id"`
Name string `json:"name"`
}
type Paging struct {
Count int `json:"count"`
Previous string `json:"previous"`
Next string `json:"next"`
}
func Get(ctx context.Context) APIResponse[T] {
results := APIResponse{}
rc, Err := r.doRequest(ctx, req)
if rc != nil {
defer rc.Close()
}
err = json.NewDecoder(rc).Decode(&results)
return results
}
示例JSON如下：
{
"count": 70,
"next": "https://api?page=2",
"previous": null,
"results": [
{
"id": 588,
"name": "Tesco"
}
...
]
}
我希望将其解码为一个形式为APIResponse的结构体，其中分页元素是一个子结构，就像results一样。然而，在示例JSON中，分页部分没有父级json标签。如何将其解码为一个单独的结构体？
目前，如果我将Count、Next和Previous提升到APIResponse中，它们会出现，但当它们是子结构时，它们不会出现。
英文:
type APIResponse struct {
Results []Result `json:"results,omitempty"`
Paging Paging
}
type Result struct {
Id string `json:"id"`,
Name string `json:"name"`,
}
type Paging struct {
Count int `json:"count"`
Previous string `json:"previous"`
Next string `json:"next"`
}
func Get(ctx context.Context) APIResponse[T] {
results := APIResponse{}
rc, Err := r.doRequest(ctx, req)
if rc != nil {
defer rc.Close()
}
err = json.NewDecoder(rc).Decode(&results)
return results
}
The Sample JSON looks like this:
{
"count": 70,
"next": "https://api?page=2",
"previous": null,
"results": [
{
"id": 588,
"name": "Tesco",
}...
and I want it decoded into a struct of the form APIResponse, where the pagination element is a substruct, like the results is. However, in the sample JSON, the pagination aspect does not have a parent json tag. How can it be decoded into it's own separate struct?
Currently, if I lift Count,Next, and Previous into the APIResponse, they appear, but they don't appear when they're a substruct.

将你的Paging结构直接嵌入到APIResponse中，如下所示：
type APIResponse struct {
Results []Result `json:"results,omitempty"`
Paging
}
type Result struct {
Id string `json:"id"`
Name string `json:"name"`
}
type Paging struct {
Count int `json:"count"`
Previous string `json:"previous"`
Next string `json:"next"`
}
这样它将按照这个结构定义的方式工作。你可以通过两种方式访问它的字段：
- 直接访问：
APIResponse.Count - 间接访问：
APIResponse.Paging.Count
英文:
Embed your Paging struct directly into APIResponse like:
type APIResponse struct {
Results []Result `json:"results,omitempty"`
Paging
}
type Result struct {
Id string `json:"id"`,
Name string `json:"name"`,
}
type Paging struct {
Count int `json:"count"`
Previous string `json:"previous"`
Next string `json:"next"`
}
This way it will work as it defined in this structure. You can access its fields two ways:
- Directly:
APIResponse.Count - Indirect:
APIResponse.Paging.Count
