Unity使用Get和Post传递json数据并转换成class对象

此文写的并不是使用UnityRequest等等Unity自带的方法。

1、Get方法

        public static async Task<string> DoGet(string requestUrl, string parms)
        {
            string reslut = "";
            string uri = ""; // url + "?" + parms;
            if (string.IsNullOrEmpty(parms))
            {
                uri = requestUrl;
            }
            else
            {
                uri = requestUrl + "?" + parms;
            }

            string responseBody = string.Empty;
            using (HttpClient httpClient = new HttpClient())
            {
                httpClient.DefaultRequestHeaders.Add("Method", "Get");
                httpClient.DefaultRequestHeaders.Add("KeepAlive", "false");
                httpClient.DefaultRequestHeaders.Add("UserAgent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");

                HttpResponseMessage response = await httpClient.GetAsync(uri);
                response.EnsureSuccessStatusCode();
                responseBody = await response.Content.ReadAsStringAsync();
            }
            return responseBody;
        }

　　调用：

  string u2 = "http://" + ip + "/api/WeatherForecast/GetGameList";
            string data2 = await HttpHelper.DoGet(u2, "");
 类名 info = JsonConvert.DeserializeObject<类名>(data2);

 

2、Post

        public static async Task<string> DoPost(string Url, object message)
        {
            try
            {
                //var res = new T();
                string jsonContent = message == null ? "" : JsonConvert.SerializeObject(message);
                string responseBody = string.Empty;
                using (HttpClient httpClient = new HttpClient())
                {
                    var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
                    httpClient.DefaultRequestHeaders.Add("Method", "Post");

                    HttpResponseMessage response = await httpClient.PostAsync(Url, content);
                    response.EnsureSuccessStatusCode();
                    responseBody = await response.Content.ReadAsStringAsync();
                    //res = (T)JsonConvert.DeserializeObject<T>(responseBody);
                    return responseBody;
                }
            }
            catch (Exception ex)
            {

                return "";
            }


        }

调用：

        string js = await HttpHelper.DoPost(@"https://****", null);
            //JObject? result = JsonConvert.DeserializeObject<JObject>(js);
            类名 info = JsonConvert.DeserializeObject<类名>(js);

 

这样写主要是省了回调，省得使用消息者模式消息满天飞。

注意使用await等待时，主线程不会锁死，而使用await时，当前的方法前要加上async，例子如下。

 

      public async void GetPostData()
        {
            string js = await HttpHelper.DoPost(@"***********", null);
            //JObject? result = JsonConvert.DeserializeObject<JObject>(js);
            PkgInfo info = JsonConvert.DeserializeObject<PkgInfo>(js);
        }

 

在把json数据转换成类对象之前，如果需要校验，则使用如下方式：

        public async void GetPostData()
        {
            string js = await HttpHelper.DoPost(@"***********************", null);
            JObject result = JsonConvert.DeserializeObject<JObject>(js);
            string errcode = result["errcode"]?.ToString();
            string errmsg = result["errmsg"]?.ToString();
　　　　　　　　//先验证errcode之后，再根据情况进行类对象的转换。
            PkgInfo info = JsonConvert.DeserializeObject<PkgInfo>(js);
        }
