RestSharp 接口请求封装类

RestSharp，在nuget中引用进项目来

这里封装了，常用的接口请求方式，Post，Get，还有file上传，header处理，鉴权等方式

using RestSharp;
using System;

namespace FinanceApi
{
    public class APIHelper
    {
        private readonly string baseUrl = "http://192.168.60.108:8081/";

        /// <summary>
        /// http请求接口
        /// </summary>
        /// <param name="url">地址</param>
        /// <param name="data">数据，json格式化后的数据</param>
        /// <param name="method">方法 POST，或者get</param>
        /// <returns></returns>
        public string HttpRequest(string url, string data, Method method, string file = null)
        {
            try
            {
                var client = new RestClient(baseUrl + url);
                var request = new RestRequest(method);
                request.RequestFormat = DataFormat.Json;
                if (file == null)
                    request.AddHeader("Content-Type", "application/json");
                else
                {
                    request.AddHeader("Content-Type", "multipart/form-data");
                    request.AddHeader("user_id", UserCache.Current_UserId.ToString());
                    request.AddHeader("username", UserCache.Current_UserName);
                }
                request.Timeout = 10000;
                if (data != null)
                    request.AddParameter("application/json; charset=utf-8", data, ParameterType.RequestBody);
                if (UserCache.CACHE_UserInfoModel != null)
                    request.AddHeader("authorization", "Bearer " + UserCache.CACHE_UserInfoModel.access_token);
                if (file != null)
                    request.AddFile("file", file);
                IRestResponse response = client.Execute(request);
                var responseContent = response.Content;
                return responseContent;
            }
            catch (Exception ex)
            {
                return null;
            }
        }
    }
}
