func testDemo() {
    let jsonStr = "[{\"name\": \"hangge\", \"age\": 100, \"phones\": [{\"name\": \"公司\",\"number\": \"123456\"}, {\"name\": \"家庭\",\"number\": \"001\"}]}, {\"name\": \"big boss\",\"age\": 1,\"phones\": [{ \"name\": \"公司\",\"number\": \"111111\"}]}]"
    
    if let jsonData = jsonStr.data(using: .utf8, allowLossyConversion: false) {
        ///使用JSONSerialization
