1.json中存在单引号,json.Unmarshal解析至结构体报错

正常的解析过程

json.Unmarshal方法只能解析双引号包裹的标准json,所以做以下处理

func TestJsonUnmarshal(t *testing.T)  {
	ClusterGeneralInfo := ClusterGeneralInfo{}
	value := "{'init_status': 'enable', 'init-time': 1638529388.948411}"
	//value = `{"init_status": "enable", "init-time": 1638529388.948411}`
    //做替换处理,将单引号替换为双引号
	value = strings.Replace(value, "'", "\"", -1)
	err := json.Unmarshal([]byte(value), &ClusterGeneralInfo)
	spew.Dump(value)
	spew.Dump(ClusterGeneralInfo)
	require.NoError(t, err)
}
