I think errors like this can be improved to json_ to_ struct. go, it is convenient for developers to make incorrect type assertions
Tracking issue for:
go.mod中go的版本是1.18,已经支持泛型,为何没有应用泛型,存在大量的重复代码和interface{}。
// MergeSlices 将多个slice合并成一个slice
func MergeSlices(slices ...[]interface{}) []interface{} {}
// MergeStrSlices 将多个slice合并成一个slice
func MergeStrSlices(slices ...[]string) []string {}
// MergeIntSlices 将多个slice合并成一个slice
func MergeIntSlices(slices ...[]int) []int {}
可以参考lancet
At the beginning of the design, due to the strong typing properties of the language, it is not recommended to define data types vaguely. So the definition of interface{}
and any
type is not supported.
However, considering the affordability of some businesses, these two types need to be supported, so this requirement will support the definition of interface{}
and any
type.
func TestJsonToStructAny1(t *testing.T) {
jsonData := `{
"name": "make",
"age": "10"
}`
type Target struct {
Name interface{} `json:"name"`
Age uint `json:"age"`
}
var target Target
err := JsonToStruct(jsonData, &target)
if err != nil {
t.Errorf("err %s", err)
return
}
}
Tracking issue for:
v1.0 为了快速适应本公司的业务,所以没有考虑any和泛型
v2.0 当前正在开发和自测中,将会在不久支持泛型和any,以兼容各个业务需求
有不少同学提出这个问题,这里统一回复一下,请大家期待后续版本的发布。
There is a bug in how jsonToStruct parses maps and slices.
type Target struct {
Followed map[string]bool `json:"followed"`
Fids []string `json:"fids"`
}
func TestJsonToStruct(t *testing.T) {
data := `
{
"followed": {
"43015653": true,
"43015666": false
},
"fids": ["43015653",43015666]
}
`
var event Target
err := JsonToStruct(data, &event)
fmt.Printf("%+v, err:%s \n", event, err)
}
The specific error description is as follows
panic: reflect.Set: value of type float64 is not assignable to type string [recovered]
panic: reflect.Set: value of type float64 is not assignable to type string

这种方法完全可以不使用反射,可以这样写func Ceil[T float32 | float64](num T) int {
if num == 0{return 0 }
return int(math.Ceil(float64(num)))
}

func Chunk[T any](slice []T, size int) [][]T {

chunks = append(chunks, slice[i:end])
