1.下载RestSharpNuGet包 ![](https://i-blog.csdnimg.cn/direct/fd278a6bc9d248ee9f130af0619ed12b.png) 2.请求类和响应类 ```cs public class ApiRequest { ///

/// 请求地址 ///

public string Route { get; set; } ///

/// 请求方式 ///

public Method Method { get; set; } ///

/// 请求参数 ///

public Object Parameters { get; set; } ///

/// 请求头，表示发送的请求的类型、数据格式等 ///

public string ContentType { get; set; } = "application/json"; } ``` ```cs public class ApiResponse { public int Code { get; set; } public string Msg { get; set; } public Object Data { get; set; } } ``` 3.封装请求工具类 ```cs public class HttpClient { private readonly RestClient Client; // 客户端 private readonly string baseUrl = "http://localhost:63615/api/"; public HttpClient() { Client = new RestClient(); } ///

/// 执行请求 ///

/// 请求数据 /// 响应数据 public ApiResponse Execute(ApiRequest ApiRequest) { var request = new RestRequest(ApiRequest.Method); request.AddHeader("Content-Type", ApiRequest.ContentType); if (ApiRequest.Parameters!= null) { // SerializeObject 序列化参数 object -> json request.AddParameter("params", JsonConvert.SerializeObject(ApiRequest.Parameters), ParameterType.RequestBody); } // 设置请求地址 Client.BaseUrl = new Uri(baseUrl + ApiRequest.Route); // 发送请求 var res = Client.Execute(request); if (res.StatusCode == System.Net.HttpStatusCode.OK) { // 反序列化响应数据 json -> object return JsonConvert.DeserializeObject(res.Content); } else { return new ApiResponse { Code = (int)res.StatusCode, Msg = res.ErrorMessage }; } } } ``` 4. 在接口中引入该类，并在构造函数中初始化 ```cs private readonly IEventAggregator _eventAggregator; ``` ```cs public LoginUCViewModel(HttpClient httpClient) { //请求Client _httpClient = httpClient; } ``` 5.注入我们的请求服务（这里我用的是prism框架，写法可能有所不同，但是思路是一样的） ```cs protected override void RegisterTypes(IContainerRegistry containerRegistry) { //请求 containerRegistry.GetContainer().Register(made: Parameters.Of.Type(serviceKey: "webUrl")); } ``` 6.发送请求 ```cs // 发送请求 ApiRequest apiRequest = new ApiRequest(); // 请求方式 apiRequest.Method = RestSharp.Method.POST; // 请求地址(这里只写这一段是因为定义的时候定义了baseUrl apiRequest.Route = "Account/Register"; AccountInfoDto.Password = Md5Helper.GetMd5(AccountInfoDto.Password); apiRequest.Parameters = AccountInfoDto; ApiResponse response = _httpClient.Execute(apiRequest); ``` 到此，简单的请求封装就结束了
