未找到 Azure 移动服务终结点（.NET 后端）答案

【问题标题】：Azure Mobile Services Endpoint not found (.NET backend)未找到 Azure 移动服务终结点（.NET 后端）
【发布时间】：2014-08-04 01:04:21
【问题描述】：

我正在构建一个简单的费用跟踪系统。当我在本地运行代码时，代码运行良好，但是当我尝试连接到 Azure 中的端点时，出现 404 错误。我什至尝试完全删除移动服务并重新发布它，但它只适用于我的本地计算机。

我用一些在 Azure SQL DB 中看到的示例数据为数据库播种，所以我知道数据在那里

当然还有我的种子方法

    List<Expense> expenses = new List<Expense>{ new Expense { Id = System.Guid.NewGuid().ToString(), Amount = 7.77, Client = "Cisco", Location = "Houston,tx", Date = DateTime.UtcNow},
    new Expense {Id = System.Guid.NewGuid().ToString(),Amount = 10.99, Client= "Microsoft", Location = "Remond, WA", Date = DateTime.UtcNow}};

    foreach (Expense exp in expenses)
    {
        context.Set<Expense>().Add(exp);
    }
    base.Seed(context);

对象的类定义

    public class Expense: EntityData
    {
        public double Amount { get; set; }

        public ExpenseCurrency? Currency { get; set; }

        public DateTime? Date { get; set; }

        public string Vender { get; set; }

        public ExpenseType? Type { get; set; }

        public string Location { get; set; }

        public string Client { get; set; }

        public string Project { get; set; }

        public bool? PersonalExpense { get; set; }

        public string UserId { get; set; }

        public int? CompanyId { get; set; }
}

更新

Azure 移动服务 SDK 似乎请求了错误的路径。它不是请求 http://{service name}.azure-mobile.net/api/Expenses 而是请求 https://{service name}.azure-mobile.net/tables/Expenses

这里是初始化

private MobileServiceCollection<Expense, Expense> expenseCollection;
private IMobileServiceTable<Expense> expenseTable = App.MobileService.GetTable<Expense>();

这里是抛出异常的地方

expenseCollection = await expenseTable.ToCollectionAsync();

更新 2

请求了费用控制器类..

public class ExpensesController : ApiController
{
    private mXpenseContext db = new mXpenseContext();

    // GET: api/Expenses
    public IQueryable<Expense> GetExpenses()
    {
        return db.Expenses;
    }

    // GET: api/Expenses/5
    [ResponseType(typeof(Expense))]
    public async Task<IHttpActionResult> GetExpense(string id)
    {
        Expense expense = await db.Expenses.FindAsync(id);
        if (expense == null)
        {
            return NotFound();
        }

        return Ok(expense);
    }

    // PUT: api/Expenses/5
    [ResponseType(typeof(void))]
    public async Task<IHttpActionResult> PutExpense(string id, Expense expense)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        if (id != expense.Id)
        {
            return BadRequest();
        }

        db.Entry(expense).State = EntityState.Modified;

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!ExpenseExists(id))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return StatusCode(HttpStatusCode.NoContent);
    }

    // POST: api/Expenses
    [ResponseType(typeof(Expense))]
    public async Task<IHttpActionResult> PostExpense(Expense expense)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        db.Expenses.Add(expense);

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateException)
        {
            if (ExpenseExists(expense.Id))
            {
                return Conflict();
            }
            else
            {
                throw;
            }
        }

        return CreatedAtRoute("DefaultApi", new { id = expense.Id }, expense);
    }

    // DELETE: api/Expenses/5
    [ResponseType(typeof(Expense))]
    public async Task<IHttpActionResult> DeleteExpense(string id)
    {
        Expense expense = await db.Expenses.FindAsync(id);
        if (expense == null)
        {
            return NotFound();
        }

        db.Expenses.Remove(expense);
        await db.SaveChangesAsync();

        return Ok(expense);
    }

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            db.Dispose();
        }
        base.Dispose(disposing);
    }

    private bool ExpenseExists(string id)
    {
        return db.Expenses.Count(e => e.Id == id) > 0;
    }
}

【问题讨论】：

请查看图片。
你能发布控制器类吗？可能是 ExpenseController.cs

标签： c# entity-framework azure

【解决方案1】：

默认情况下，移动服务 (.Net) 中的控制器从 TableController 继承，如您的错误消息所示，它正在寻找到 /tables/expenses 的路由。由于您的控制器继承自 ApiController（根据 webApi 完全可以），您应该能够添加路由属性以获得所需的结果。

// GET: api/Expenses
[Route("api")]
public IQueryable<Expense> GetExpenses()
{
    return db.Expenses;
}

// GET: api/Expenses/5
[Route("api/{id}"]
[ResponseType(typeof(Expense))]
public async Task<IHttpActionResult> GetExpense(string id)
{
    Expense expense = await db.Expenses.FindAsync(id);
    if (expense == null)
    {
        return NotFound();
    }

    return Ok(expense);
}

更新了费用控制器，我仍然遇到同样的问题。我怀疑问题出在我的客户端配置上，而不是控制器类。连接到该服务的 Windows Phone 客户端请求的路径错误。
听起来确实可能是问题所在。我通常使用 Fiddler (telerik.com/fiddler) 测试服务并在 GET 方法上添加断点，然后您可以确定服务是否按预期执行。告诉我你的进展情况

【解决方案2】：

似乎问题出在我的控制器上。它是从 ApiController 继承的，但将其切换到 TableController 解决了这个问题。搭建脚手架时，请确保使用“windows mobile services table controller”选项

【解决方案3】：

您的控制器应显示在帮助页面下，您可以在本地和托管时看到该页面。如果托管，则使用您的主密钥作为密码（用户名无关紧要）。

TableController 连接在 /tables/* 路径下，而所有其他控制器连接在 /api/* 对于 TableControllers，您可以使用客户端表 API，对于所有其他控制器，您可以使用自定义 API。

谢谢，

亨里克
