Serializing an object with restsharp and passing it to WebApi not serializing list
提问by Diver Dan
I have a a view model that looks like.
我有一个看起来像的视图模型。
public class StoreItemViewModel
{
public Guid ItemId { get; set; }
public List<Guid> StoreIds { get; set; }
[Required]
public string Description { get; set; }
//[Required]
//[DataMember(IsRequired = true)]
public int ItemTypeId { get; set; }
}
I have a small helper that using is using RestSharp.
我有一个使用 RestSharp 的小帮手。
public static IRestResponse Create<T>(object objectToUpdate, string apiEndPoint) where T : new()
{
var client = new RestClient(CreateBaseUrl(null))
{
Authenticator = new HttpBasicAuthenticator("user", "Password1")
};
var request = new RestRequest(apiEndPoint, Method.POST);
//request.JsonSerializer = new JsonSerializer();
// {RequestFormat = DataFormat.Json};
request.AddObject(objectToUpdate);
// clientJsonSerializer = new YourCustomSerializer();
var response = client.Execute<T>(request);
return response;
}
When debugging the controller within my api
在我的 api 中调试控制器时
[HttpPost]
public HttpResponseMessage Create([FromBody]StoreItemViewModel myProduct)
{
//check fields are valid
.........
}
myProducts products are all populated apart from the public List StoreIds it always is returning a single reward with an empty Guid. Even if I have added 2 or more StoreIds
除了公共列表 StoreIds 之外，myProducts 产品都被填充，它总是返回一个带有空 Guid 的奖励。即使我添加了 2 个或更多 StoreId
I assume this is because I am doing something wrong with my Create helper within my application.
我认为这是因为我在我的应用程序中的 Create helper 做错了。
Can anyone help with this its causing a major headache.
任何人都可以帮助解决这个问题，这会导致严重的头痛。
The raw data sent to the webapi is looking like
发送到 webapi 的原始数据看起来像
ItemId=f6dbd244-e840-47e1-9d09-53cc64cd87e6&ItemTypeId=6&Description=blabla&StoreIds=d0f36ef4-28be-4d16-a2e8-37030004174a&StoreIds=f6dbd244-e840-47e1-9d09-53cc64cd87e6&StoreId=d0f36ef4-28be-4d16-a2e8-37030004174a

I managed to get this working. I don't think its the correct way but it works.
我设法让这个工作。我不认为它是正确的方法，但它有效。
public static IRestResponse Create<T>(object objectToUpdate, string apiEndPoint) where T : new()
{
var client = new RestClient(CreateBaseUrl(null))
{
Authenticator = new HttpBasicAuthenticator("user", "Password1")
};
var json = JsonConvert.SerializeObject(objectToUpdate);
var request = new RestRequest(apiEndPoint, Method.POST);
request.AddParameter("text/json", json, ParameterType.RequestBody);
var response = client.Execute<T>(request);
return response;
}

I struggled with the same problem and came up a working solution.
我遇到了同样的问题，并提出了一个可行的解决方案。
Be sure to set the request format to JSON:
request.RequestFormat = DataFormat.Json;
Use AddBody, rather than AddObject:
request.AddBody(zNewSessionUsage);
请务必将请求格式设置为 JSON：
request.RequestFormat = DataFormat.Json;
使用 AddBody，而不是 AddObject：
request.AddBody(zNewSessionUsage);
So your code would be something like this:
所以你的代码应该是这样的：
public static IRestResponse Create<T>(object objectToUpdate, string apiEndPoint) where T : new()
{
var client = new RestClient(CreateBaseUrl(null))
{
Authenticator = new HttpBasicAuthenticator("user", "Password1")
};
var request = new RestRequest(apiEndPoint, Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(objectToUpdate);
var response = client.Execute<T>(request);
return response;
}

RestSharp now has a more streamlined way to add an object to the RestRequest Body with Json Serialization:
RestSharp 现在有一种更简化的方法来使用 Json 序列化将对象添加到 RestRequest Body：
public static IRestResponse Create<T>(object objectToUpdate, string apiEndPoint) where T : new()
{
var client = new RestClient(CreateBaseUrl(null))
{
Authenticator = new HttpBasicAuthenticator("user", "Password1")
};
var request = new RestRequest(apiEndPoint, Method.POST);
request.AddJsonBody(objectToUpdate); // HERE
var response = client.Execute<T>(request);
return response;
}
