Functions ¶
Types ¶
type Json ¶
type Json struct {
// contains filtered or unexported fields
}
func NewFromAny ¶
func NewFromAny(data interface{}) *Json
New returns a pointer to a new, empty `Json` object
func NewFromReader ¶
NewFromReader returns a *Json by decoding from an io.Reader
func NewJson ¶
NewJson returns a pointer to a new `Json` object after unmarshaling `body` bytes
func (*Json) CheckGet ¶
CheckGet returns a pointer to a new `Json` object and a `bool` identifying success or failure
useful for chained operations when success is important:
if data, ok := js.Get("top_level").CheckGet("inner"); ok {
log.Println(data)
}
func (*Json) Del ¶
Del modifies `Json` map by deleting `key` if it is present.
func (*Json) Encode ¶
Encode returns its marshaled data as `[]byte`
func (*Json) EncodePretty ¶
EncodePretty returns its marshaled data as `[]byte` with indentation
func (*Json) Get ¶
Get returns a pointer to a new `Json` object for `key` in its `map` representation
useful for chaining operations (to traverse a nested JSON):
js.Get("top_level").Get("dict").Get("value").Int()
func (*Json) GetIndex ¶
GetIndex returns a pointer to a new `Json` object for `index` in its `array` representation
this is the analog to Get when accessing elements of a json array instead of a json object:
js.Get("top_level").Get("array").GetIndex(1).Get("key").Int()
func (*Json) GetPath ¶
GetPath searches for the item as specified by the branch without the need to deep dive using Get()'s.
js.GetPath("top_level", "dict")
func (*Json) Interface ¶
func (j *Json) Interface() interface{}
Interface returns the underlying data
func (*Json) MarshalJSON ¶
Implements the json.Marshaler interface.
func (*Json) MustArray ¶
func (j *Json) MustArray(args ...[]interface{}) []interface{}
MustArray guarantees the return of a `[]interface{}` (with optional default)
useful when you want to interate over array values in a succinct manner:
for i, v := range js.Get("results").MustArray() {
fmt.Println(i, v)
}
func (*Json) MustBool ¶
MustBool guarantees the return of a `bool` (with optional default)
useful when you explicitly want a `bool` in a single value return context:
myFunc(js.Get("param1").MustBool(), js.Get("optional_param").MustBool(true))
func (*Json) MustFloat64 ¶
MustFloat64 guarantees the return of a `float64` (with optional default)
useful when you explicitly want a `float64` in a single value return context:
myFunc(js.Get("param1").MustFloat64(), js.Get("optional_param").MustFloat64(5.150))
func (*Json) MustInt ¶
MustInt guarantees the return of an `int` (with optional default)
useful when you explicitly want an `int` in a single value return context:
myFunc(js.Get("param1").MustInt(), js.Get("optional_param").MustInt(5150))
func (*Json) MustInt64 ¶
MustInt64 guarantees the return of an `int64` (with optional default)
useful when you explicitly want an `int64` in a single value return context:
myFunc(js.Get("param1").MustInt64(), js.Get("optional_param").MustInt64(5150))
func (*Json) MustMap ¶
MustMap guarantees the return of a `map[string]interface{}` (with optional default)
useful when you want to interate over map values in a succinct manner:
for k, v := range js.Get("dictionary").MustMap() {
fmt.Println(k, v)
}
func (*Json) MustString ¶
MustString guarantees the return of a `string` (with optional default)
useful when you explicitly want a `string` in a single value return context:
myFunc(js.Get("param1").MustString(), js.Get("optional_param").MustString("my_default"))
func (*Json) MustStringArray ¶
MustStringArray guarantees the return of a `[]string` (with optional default)
useful when you want to interate over array values in a succinct manner:
for i, s := range js.Get("results").MustStringArray() {
fmt.Println(i, s)
}
func (*Json) MustUint64 ¶
MustUInt64 guarantees the return of an `uint64` (with optional default)
useful when you explicitly want an `uint64` in a single value return context:
myFunc(js.Get("param1").MustUint64(), js.Get("optional_param").MustUint64(5150))
func (*Json) Set ¶
Set modifies `Json` map by `key` and `value` Useful for changing single key/value in a `Json` object easily.
func (*Json) SetPath ¶
SetPath modifies `Json`, recursively checking/creating map keys for the supplied path, and then finally writing in the value
func (*Json) StringArray ¶
StringArray type asserts to an `array` of `string`
