访问 Azure MobileServices TableController 时出现服务器错误答案

【问题标题】：Server Errors while accessing Azure MobileServices TableController访问 Azure MobileServices TableController 时出现服务器错误
【发布时间】：2017-10-27 23:44:16
【问题描述】：

我使用 Azure 移动应用 模板创建了一个 TableController API 并部署到 azure。

我从 URL 进行了测试，当我使用以下 URL 时它工作正常

http://rkXXXXXXXXXXX.azurewebsites.net/tables/Person/f90cb37d51a34f8cb97432a57000c876?ZUMO-API-VERSION=2.0.0

现在我创建了 Xamarin Forms 应用来使用它，但我在日志中收到 Internal Server Error 并且无法使用它。

public IMobileServiceTable<Person> PersonOnlineTable { get; set; }
PersonOnlineTable = client.GetTable<Person>();
    public async Task SavePersonAsync(Person item)
    {
        if (item.Id == null)
        {
            await PersonOnlineTable.InsertAsync(item);
        }
        else
        {
            await PersonOnlineTable.UpdateAsync(item);
        }
    }

Azure 日志记录错误

我尝试多次部署服务器应用程序，它始终从 MainURL 工作，而在从 App 调用时不工作。有什么想法可以解决这个问题吗？

【问题讨论】：

如果您在本地调试移动服务并将您的应用指向该位置会发生什么？

标签： azure xamarin.forms azure-mobile-services

【解决方案1】：

由于模型对象中的数据类型不匹配而发生此问题。我有日期时间对象，在数据库中定义为 datetimeoffset，在 DTO 对象中定义为 datetime。更改我的 DTO 对象的数据类型后，它工作正常。
