HttpClient是什么和为什么？

Question

什么是HttpClient？它是什么？从我需要开始为api控制器编写简单的http客户端？我需要它来简单访问控制器。

Answer 1

这应该给你一个开始：

private Order SendOrderRequest(Models.OrderTest model) 
{ 
    Uri uri = new Uri(model.BaseUrl + "order"); 

    HttpClient client = new HttpClient(); 

    client.BaseAddress = uri; 

    var mediaType = new MediaTypeHeaderValue("application/json"); 
    var jsonFormatter = new JsonMediaTypeFormatter(); 

    HttpContent content = new ObjectContent<Order>(model.Order, jsonFormatter); 
    HttpResponseMessage responseMessage = client.PostAsync(uri, content).Result; 

    return responseMessage.Content.ReadAsAsync(typeof(Supertext.API.POCO.Order)).Result as Supertext.API.POCO.Order; 
} 

它只是岗位模型内部订单对象到Web API（并得到一个订单对象返回）
