ASP.Net Web API は初めてです。Recurly REST ベースの API と対話しようとしていますが、ReadAsAsync 呼び出し中に以下のようなエラーが発生します。これは、応答をシリアル化しようとしていると思われるポイントです。
{"Error in line 1 position 73. Expecting element 'account' from namespace 'http://schemas.datacontract.org/2004/07/RecurlyWebApi.Recurly'.. Encountered 'Element' with name 'account', namespace ''. "}
簡潔にするために簡略化した、私の HttpClient 実装を次に示します。
public class RecurlyClient
{
readonly HttpClient client = new HttpClient();
public RecurlyClient()
{
var config = (RecurlySection)ConfigurationManager.GetSection("recurly");
client.BaseAddress = new Uri(string.Format("https://{0}.recurly.com/v2/", config.Subdomain));
// Add the authentication header
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(config.ApiKey)));
// Add an Accept header for XML format.
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
}
public T Get<T>(string id)
{
var accounts = default(T);
// Make the request and get the response from the service
HttpResponseMessage response = client.GetAsync(string.Concat("accounts/", id)).Result; // Blocking call!
if (response.IsSuccessStatusCode)
{
// Parse the response body. Blocking!
accounts = response.Content.ReadAsAsync<T>().Result;
}
return accounts;
}
}
そして、ここに私のモデルがあります:
[XmlRoot("account")]
public class Account
{
[XmlAttribute("href")]
public string Href { get; set; }
[XmlElement("account_code")]
public string AccountCode { get; set; }
[XmlElement("state")]
public AccountState State { get; set; }
[XmlElement("username")]
public string Username { get; set; }
[XmlElement("email")]
public string Email { get; set; }
[XmlElement("first_name")]
public string FirstName { get; set; }
[XmlElement("last_name")]
public string LastName { get; set; }
[XmlElement("company_name")]
public string Company { get; set; }
[XmlElement("accept_language")]
public string LanguageCode { get; set; }
[XmlElement("hosted_login_token")]
public string HostedLoginToken { get; set; }
[XmlElement("created_at")]
public DateTime CreatedDate { get; set; }
[XmlElement("address")]
public Address Address { get; set; }
}
