我正在尝试从Web API
接收到的JSON字符串try
{
string r = await App.client.GetUser();
App.Authentication = JsonConvert.DeserializeObject<ApiResult>(r);
await DisplayAlert("TEST", App.Authentication.ToString(), "OK");
Application.Current.MainPage = new Schedule();
}
catch (Exception p)
{
await DisplayAlert("Getting Authentication failed", p.ToString(), "TEST");
}
但是它给出了错误:无法施放或转换system.string到app1.apiresult App.Authentication = JsonConvert.DeserializeObject<ApiResult>(r);
app.authentication:
public static ApiResult Authentication = new ApiResult();`
json字符串:
" " {\" status \":\" 0 \",\" message \":{\" id \":5,\ \" firstname \":\" john \",\" lastname \":\" doe \",\" email \":\" testemail@gmail.com \",\" password \ \":\" testpass \",\" CreationDate \":\" 2016-10-26T15:01:08 \",\" releid \":1,\ doorcode \'otor Code \\\\\\\\\\\\\\\\":9999}} "
apiresult类:
public class ApiResult
{
public string status { get; set; }
public Account message { get; set; }
}
帐户类:
public class Account
{
public string status { get; set; }
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string Password { get; set; }
public DateTime CreationDate { get; set; }
public int RoleID { get; set; }
public int doorCode { get; set; }
}
完整错误消息:
{"错误转换值 " {"状态":" 0 "," messages ":{" ID ":5," firstName ":" john ",", " lastName ":":"doe "," email ":" testemail@gmail.com "," password ":" testpass "," creationdate ":" 2016-10-26T15:01:01:08 "," releid ":1,"门代码":9999}}} " 键入'app1.apiresult'。路径'',第1行,位置232。"}
看来,您收到的JSON已被序列化两次 - 首先是从ApiResult
到string
,然后再次到string
:
""{\"status\":\"0\",\"message\":...
您的调试器可能会添加第一个双引号,但是第二个引号(逃脱的"
One)似乎确实是您正在处理的数据的一部分。错误消息也很有意义,它值得将string
划分,然后尝试将其投射到ApiResult
。
尝试将数据当作字符串,然后然后将其结果列为ApiResult
,以确保是这种情况 - 如果是这样,则需要更改服务器代码。
下面的代码沿着我的c.evenhuis答案为我工作,
var content = response.Content;
var jsonResult = JsonConvert.DeserializeObject(content).ToString();
var result= JsonConvert.DeserializeObject<Model>(jsonResult);
这里的内容类似于 - " " {\" id \":\" 92209 \",\" operatorId \":100000,\" status \":true,.....
尝试使用app.authentication = jobign.parse(request.content.content.readasstringasync()。结果);
