Flutter http对象列表

Question

作为示例，我可以如何请求一个简单的正文元素

 //Sets static IP
    public static void SetStaticIP(string ip, string newIP, string subnet = "255.255.255.0")
    {
        ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection objMOC = objMC.GetInstances();

        foreach (ManagementObject objMO in objMOC)
        {
            if ((bool)objMO["IPEnabled"])
            {
                try
                {
                    object x = objMO["IPAddress"];
                    string[] str = (string[])x;
                    if (str[0] == ip)
                    {
                        ManagementBaseObject objNewIP = null;
                        ManagementBaseObject objSetIP = null;
                        objNewIP = objMO.GetMethodParameters("EnableStatic");

                        objNewIP["IPAddress"] = new string[] {newIP};
                        objSetIP = objMO.InvokeMethod("EnableStatic", objNewIP, null);
                    }
                }
                catch (Exception ex)
                {
                    Console.WriteLine("Unable to Set IP : " + ex.Message);
                }

            }
        }
    }

    //sets allocation to DHCP
    public static bool setDHCP(string oldIP)
    {
        ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection objMOC = objMC.GetInstances();

        foreach (ManagementObject objMO in objMOC)
        {
            if (!(bool)objMO["IPEnabled"])
            {
                object x = objMO["IPAddress"];
                string[] str = (string[])x;
                if (str[0] == oldIP)
                {
                    try
                    {
                        ManagementBaseObject objNewDNS = null;
                        ManagementBaseObject objSetDNS = objMO.GetMethodParameters("EnableDHCP");

                        objNewDNS = objMO.InvokeMethod("EnableDHCP", null, null);

                        return true;
                    }
                    catch (Exception) { return false; }
                }
            }
        }
        return false;
    }

我的问题是如何处理这个复杂的问题？

var body = jsonEncode({

      "name":"username",
      "phone":"-",

    });

我有"items" :[ { "product_id" :9, "quantity" : 2, "price" : 20 }, { "product_id" : 10, "quantity" : 3 , "price" : 20 } ] 的鞭子包含所有数据

Answer 1

http.get("url").then((response) {
      map = json.decode(response.body);
}
