Any.ToInt() resulting not nil LastError() ?

[huangjunwen]

Consider the following test case, all 6 cases are valid json values. Only number will cause a not nil LastError()

package any_test

import (
	"github.com/json-iterator/go"
	"github.com/stretchr/testify/assert"
	"testing"
)

func TestAny(t *testing.T) {
	for _, s := range []string{
		`-32000`,
		`"hello"`,
		`false`,
		`null`,
		`{"a":300}`,
		`[]`,
	} {
		a := jsoniter.Get([]byte(s))
		assert.NoError(t, a.LastError(), "Any.Get(%+q) should have no error", s)
		switch a.ValueType() {
		case jsoniter.NumberValue:
			_ = a.ToInt()
		case jsoniter.StringValue:
			_ = a.ToString()
		case jsoniter.BoolValue:
			_ = a.ToBool()
		case jsoniter.NilValue:

		case jsoniter.ObjectValue:
			var v map[string]interface{}
			a.ToVal(&v)
		case jsoniter.ArrayValue:
			var v []interface{}
			a.ToVal(&v)
		}
		assert.NoError(t, a.LastError(), "Any(%+q) ToXXX should have no error", s)
	}

}

Output:
