后台发送get请求

1.发送带参数的get请求

    /// <summary>  
    /// 发送get请求 参数拼接在url后面  
    /// </summary>  
    /// <param name="url">请求接口地址</param>  
    /// <returns></returns>  
    public static string HttpGet(string url)  
    {  
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);  
        request.Method = "GET";  
        //设置发送请求的类型  
        request.ContentType = "text/html;charset=UTF-8";// "application/json";  
        //设置请求超时时间  
        request.Timeout = 60 \* 1000;

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();  
        using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))  
        {  
            string strResult = reader.ReadToEnd();  
            reader.Close();  
            response.Close();  
            return strResult;  
        }  
    }

2.后台接收请求API

    /// <summary>  
    /// 获取站点信息  
    /// </summary>  
    /// <returns></returns>  
    \[HttpGet\]  
    \[Route("GetStationInfo")\]  
    public ActionResult GetStationInfo(string stationName)  
    {  
        List<StationInfo> station= \_stationServices.GetStationList().Where(p => p.StationName == stationName).ToList();  
        return new JsonResult(new { code = 1000, data = station });  
    }

后台发送post请求

1.发送带参数的post请求

        string url = "https://localhost:44319/api/Station/AddStationInfo";  
        StationInfo stationInfo = new StationInfo()  
        {  
            StationGuid = Guid.NewGuid().ToString(),  
            StationName = "站点10",  
            UpdateTime = DateTime.Now  
        };  
        //传递json格式字符串信息  
        var jsonStr = JsonConvert.SerializeObject(stationInfo);  
        var result = HttpPost(url, jsonStr);  
        var returnData = JsonConvert.DeserializeObject<ReturnData>(result); 

2.后台请求的方法

    /// <summary>  
    /// 发送post请求 参数在Body中  
    /// </summary>  
    /// <param name="url">请求接口地址</param>  
    /// <param name="json">json字符串</param>  
    /// <returns></returns>  
    public static string HttpPost(string url, string json)  
    {  
        //创建请求  
        HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;  
        //请求方式为POST  
        request.Method = "POST";  
        request.ContentType = "application/json";  
        //设置请求超时时间  
        request.Timeout = 60 \* 1000;  
        try  
        {  
            //添加post请求参数  
            byte\[\] bs = Encoding.UTF8.GetBytes(json);  
            using (Stream reqStream = request.GetRequestStream())  
            {  
                reqStream.Write(bs, 0, bs.Length);  
                reqStream.Close();  
            }  
            //发送请求并获取相应回应数据  
            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())  
            {  
                using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII))  
                {  
                    string content = reader.ReadToEnd();  
                    return content;  
                }  
            }  
        }  
        catch (WebException ex)  
        {  
            return string.Format("错误信息：{0}，传输json串：{1}", ex.Message, json);  
        }  
    }

3.后台接收请求API

    /// <summary>  
    /// 添加站点信息  
    /// </summary>  
    /// <param name="station"></param>  
    /// <returns></returns>  
    \[HttpPost\]  
    \[Route("AddStationInfo")\]  
    public ActionResult AddStationInfo(StationInfo station)  
    {  
        try  
        {  
            StationInfo stationInfo = new StationInfo();  
            stationInfo.StationGuid = station.StationGuid;  
            stationInfo.StationName = station.StationName;  
            stationInfo.UpdateTime = station.UpdateTime;  
            string result = \_stationServices.AddStation(stationInfo) > 0 ? "添加成功" : "添加失败";  
            return new JsonResult(new { code = 1000, data = result });  
        }  
        catch (Exception ex)  
        {  
            return new JsonResult(new { code = 1000, data = ex.Message });  
        }  
    }
