Question

我想与社区分享在使用控制台应用程序和与WebAPI服务调用进行通信时必须克服的问题。

将简单类型作为参数传递是直接的，但传递复杂类型并不简单。我需要以某种方式序列化类型并将其作为参数传递。我的方法如下。我希望有人发现这个有用的

WebAPI方法：

      public IHttpActionResult PurchaseOrders([FromUri]string parameters)
      {
      var criteria = new JavaScriptSerializer().Deserialize<PurchaseOrderManager.Criteria>(parameters);
      var result = PurchaseOrderManager.PurchaseOrderSummary(criteria);
      return Content(HttpStatusCode.OK, result);
      }

调用服务的客户端方法......

 private static async Task<List<PurchaseOrderListModel>> GetPendingPurchaseOrdersByUser(string token, UserModel userModel)
{
    var service = ConfigurationManager.AppSettings["service:address"];

    using (var client = new HttpClient())
    {
        client.BaseAddress = new Uri(service);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);

        var content = new StringContent(JsonConvert.SerializeObject(new
        {
            Filter = "PENDING",
            RequestType = "REQUEST"
        }), Encoding.UTF8, "application/json");
        var paramsValue = content.ReadAsStringAsync().Result;


        HttpResponseMessage response = await client.GetAsync($"purchaseorders/purchaseorders?parameters={paramsValue}");
        if (response.IsSuccessStatusCode)
        {

            var purchaseOrders = response.Content.ReadAsAsync<List<PurchaseOrderListModel>>().Result;
            //do work....
            //return some value
        }
    }
    return null;
}

使用客户端应用程序中的HttpClient将对象参数提交到WebAPI
