Question

我有asp.net mvc5项目，我想用JSON调用另一个API，我想从我的Controller操作中调用该API，因为我需要在那里进行一些散列，

这是我第一次这样做，我需要用JSON发送请求，并使用控制器操作在JSON中获取所有响应。

如果您的方法是POST：

                string uri = "yourdomain/api/controller/method;

                var client = new HttpClient();
                var values = new Dictionary<string, string>()
                    {
                        {"username", SecurityHelper.EncryptQueryString(username)},
                        {"password", SecurityHelper.EncryptQueryString(password)},
                    };
                var content = new FormUrlEncodedContent(values);
                var response = await client.PostAsync(uri, content);
                response.EnsureSuccessStatusCode();

如果你的方法是GET：

                    string url = "domain/api/controller/method?parameter1=param";
                    using (var client = new HttpClient())
                    {
                        HttpResponseMessage response = await client.GetAsync(url).ConfigureAwait(false);
                        if (response.IsSuccessStatusCode)
                        {
                            var jsonResponse = response.Content.ReadAsStringAsync().Result;
                            bool data = JsonConvert.DeserializeObject<bool>(jsonResponse);
                            return data;
                        }
                    }

        var client = new HttpClient();
        var payload = @"{
           'CPU': 'Intel',
           'PSU': '500W',
           'Drives': [
             'DVD read/writer',
             '500 gigabyte hard drive',
             '200 gigabype hard drive'
           ]
        }";

        var content = new StringContent(payload, Encoding.UTF8, "application/json");
        var url = {APIEndpoint};
        var result = await client.PostAsync(url, content);

使用JSON.NET进行响应解析：

JObject joResponse = JObject.Parse(result);
