WPF怎么通过RestSharp向后端发请求

1.下载RestSharpNuGet包

2.请求类和响应类

public class ApiRequest
{/// <summary>/// 请求地址/// </summary>public string Route { get; set; }/// <summary>/// 请求方式/// </summary>public Method Method { get; set; }/// <summary>/// 请求参数/// </summary>public Object Parameters { get; set; }/// <summary>/// 请求头，表示发送的请求的类型、数据格式等/// </summary>public string ContentType { get; set; } = "application/json";
}

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

 public class HttpClient{private readonly RestClient Client; // 客户端private readonly string baseUrl = "http://localhost:63615/api/";public HttpClient(){Client = new RestClient();}/// <summary>/// 执行请求/// </summary>/// <param name="request">请求数据</param>/// <returns>响应数据</returns>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 -> jsonrequest.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 -> objectreturn JsonConvert.DeserializeObject<ApiResponse>(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

private readonly IEventAggregator _eventAggregator;

public LoginUCViewModel(HttpClient httpClient)
{//请求Client_httpClient = httpClient;
}

5.发送请求

// 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
