我正在创建一个Web API端点,它将作为一种服务来检索我们的应用程序配置,执行日志记录等.我遇到的问题是能够在控制台应用程序中反序列化Json.
建立
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
}
Web API
[HttpGet]
[Route("Person")]
public IHttpActionResult GetPerson()
{
Person person = new Person
{
FirstName = "Steve",LastName = "Rogers",DateOfBirth = new DateTime(1920,7,4)
};
return Ok(JsonConvert.SerializeObject(person));
}
控制台应用
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost");
var response = client.GetAsync("api/Person").Result;
var data = response.Content.ReadAsStringAsync().Result;
var person = DeserializeJson<Person>(data);
}
public static T DeserializeJson<T>(string input)
{
var result = JsonConvert.DeserializeObject(input);
var result2 = JsonConvert.DeserializeObject(result.ToString());
return JsonConvert.DeserializeObject<T>(result2.ToString());
}
值
data = “\”{\\”FirstName\\”:\\”Steve\\”,\\”LastName\\”:\\”Rogers\\”,\\”DateOfBirth\\”:\\”1920-07-04T00:00:00\\”}\””
result = “{\”FirstName\”:\”Steve\”,\”LastName\”:\”Rogers\”,\”DateOfBirth\”:\”1920-07-04T00:00:00\”}”
result2 = {{
“FirstName”: “Steve”,
“LastName”: “Rogers”,
“DateOfBirth”: “1920-07-04T00:00:00”
}}
我遇到的问题是,在第3次反序列化之前,我无法反序列化为Person对象. result2中的值是我能够成功反序列化为Person的唯一值.有没有更有效的方法来完成这种反序列化？优选地,没有3次迭代.
解决方法
我能够成功运行以下内容(基于
this Microsoft article)：
控制台应用：
static void Main(string[] args)
{
RunAsync().Wait();
}
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:3963/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync("api/Person");
Person product = await response.Content.ReadAsAsync<Person>();
}
}
控制器：
public class PersonController : ApiController
{
public Person GetPerson()
{
Person person = new Person
{
FirstName = "Steve",4)
};
return person;
}
}
