c# - 如何在 xamarin.android 中使用 HttpClient 将数据传递到服务器

Question

我正在用 xamarin 开发一个 android 应用程序，现在我想发出 post 请求并将以下数据发送到服务器

Name 
EmailID
Prod_EMAILID
ID

并从服务器获取响应Link of API .我做过这样的事

static async Task CallWebAPIAsync()
{
    using (var client = new HttpClient())
    {
        client.BaseAddress = new Uri("http://localhost:55587/");
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));                

        //POST Method
        var post = new Post() { Id = 1,NAME="aaaaa222",PROF_EMAILD="aaa@gmail.com",MAILID="asasa@gmail.com" };
        HttpResponseMessage responsePost = await client.PostAsJsonAsync("api/Department", post);
        if (responsePost.IsSuccessStatusCode)
        {
            // Get the URI of the created resource.
            Uri returnUrl = responsePost.Headers.Location;
            Console.WriteLine(returnUrl);
        }        
    }
    Console.Read();    
}

但它只适用于 GET 方法，现在我想在 Httpclient 中发出 post 请求

Answer 1

这是我在解决方案中使用 HttpClient 的方式

using (var client = new HttpClient())
{
    var content = new StringContent(JsonConvert.SerializeObject(myPoco));
    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

    var response = await client.PostAsync(new Uri("http://your-url"), content);

    /* handle response here*/
};

myPoco 是您的普通 C# 对象
