Question

尝试将嵌套数组发布到ServiceStack休息端点时出现错误。

我得到的错误是：

KeyValueDataContractDeserializer：转换为类型时出错：类型定义应以'{'开头，期待序列化类型 'DeployServer'，字符串以：object Object]“
开头

我的班级结构如下：

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; }
}

邮政编码非常简单：

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，对我来说很好看：

{
  "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，这就是我从get中删除的JSON，我只是想把它发回去

我做错了什么？

由于

使用原始HTTP请求更新：

答案感谢mythz的答案，他是对的，我是双重发帖。问题是我调用AngularJS资源库以这种方式保存：

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

我应该这样称呼它：

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

您在QueryString和Request Body中双重发布请求。在QueryString中，使用JSV Format解析复杂类型。

将URL更改为选定的路径，即：

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

然后解析请求正文应该没问题，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,
    ProjectId: 03b5635a-7eb8-4aeb-80e0-461f29c4488c,
    EnvironmentName: QA,
    ServerList: 
    [
        {

            EnvironmentId: 300b1bd2-af16-47bb-a167-407ec8966167,
            ServerName: Server1
        },

        }
    ]
