c# - ServiceStack 嵌套数组错误 : KeyValueDataContractDeserializer: Error converting to type: Type definitions should start with a '{'

Question

尝试将嵌套数组发布到 ServiceStack 剩余端点时出现错误。

我得到的错误是:

KeyValueDataContractDeserializer: Error converting to type: Type definitions should start with a '{', expecting serialized type 'DeployServer', got string starting with: object Object]"

我的类结构如下:

public class DeployEnvironment
{
    public string Id { get; set; }
    public string ProjectId { get; set; }
    public string EnvironmentName { get; set; }
    public List<DeployServer> ServerList { get; set; }

    public DeployEnvironment()
    {
        this.ServerList = new List<DeployServer>();
    }
}
public class DeployServer
{
    public string Id { get; set; }
    public string EnvironmentId { get; set; }
    public string ServerName { get; set; }
}

邮政编码很简单:

public object Post(DeployEnvironment environment)
{
    if (string.IsNullOrEmpty(environment.Id))
    {
        return _projectManager.CreateEnvironment(environment.ProjectId, environment.EnvironmentName, environment.ServerList);
    }
    else
    {
        return _projectManager.UpdateEnvironment(environment.Id, environment.ProjectId, environment.EnvironmentName, environment.ServerList);
    }
}

这是我发送的 JSON，我觉得没问题:

{
  "id": "300b1bd2-af16-47bb-a167-407ec8966167",
  "projectId": "03b5635a-7eb8-4aeb-80e0-461f29c4488c",
  "environmentName": "QA",
  "serverList": [
    {
      "id": "6024e867-f858-47cb-93f4-dd592adb02af",
      "environmentId": "300b1bd2-af16-47bb-a167-407ec8966167",
      "serverName": "Server1"
    },
    {
      "id": "efcc3a14-3d4a-4990-b106-d5a81188ee04",
      "environmentId": "300b1bd2-af16-47bb-a167-407ec8966167",
      "serverName": "Server2"
    }
  ]
}

事实上，这与我从 get 中提取的 JSON 相同，我只是想将其发回

我做错了什么吗？

谢谢

回答感谢 mythz 的回答，他是对的，我在重复发布。问题是我调用 AngularJS 资源库以这种方式保存:

$scope.environment.$save($scope.environment);

我应该这样调用它:

var saveParams = {
    id: $routeParams.environmentId,
    projectId: $routeParams.projectId
};
$scope.environment.$save(saveParams);

您在查询字符串和请求正文中重复发布了请求。当使用 JSV Format 解析 QueryString 复杂类型时.

将 URL 更改为仅选择的路由，即:

/api/project/03b5635a-7eb8-4aeb-80e0-461f29c4488c/environment

然后解析请求体应该没问题，例如:

var json = @"{""id"":""300b1bd2-af16-47bb-a167-407ec8966167"",""projectId"":""03b5635a-7eb8-4aeb-80e0-461f29c4488c"",""environmentName"":""QA"",""serverList"":[{""id"":""6024e867-f858-47cb-93f4-dd592adb02af"",""environmentId"":""300b1bd2-af16-47bb-a167-407ec8966167"",""serverName"":""Server1""},{""id"":""efcc3a14-3d4a-4990-b106-d5a81188ee04"",""environmentId"":""300b1bd2-af16-47bb-a167-407ec8966167"",""serverName"":""Server2""}]}";
var dto = json.FromJson<DeployEnvironment>();

dto.PrintDump();

输出:

/*

    Id: 300b1bd2-af16-47bb-a167-407ec8966167,

        }
    ]
}
