Question

我正在构建一个简单的费用跟踪系统。我在本地运行它时代码工作正常，但当我尝试连接到Azure中的端点时，我得到404错误。我甚至试图完全删除移动服务并重新发布它，但它只能在我的本地机器上运行。

我使用Azure SQL DB中的一些示例数据为数据库播种，因此我知道数据存在

sql db

当然是我的种子方法

    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def

    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

似乎Azure移动服务SDK正在请求错误的路径。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

这是init

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

这里是引发异常的地方

expenseCollection = await expenseTable.ToCollectionAsync();

请求了feecontroller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)
        {

            {
                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

            }
        }

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

        }

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

        return Ok(expense);

    private bool ExpenseExists(string id)

        return db.Expenses.Count(e => e.Id == id) > 0;
    }
}

Answer 1

默认情况下，移动服务（.Net）中的控制器继承自TableController，如您的错误消息所示，其中它寻找到/ tables / expenses的路由。由于您的控制器继承自ApiController（完全可以按照webApi），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);
}

Answer 2

似乎问题出在我的控制器上。它继承自ApiController，但将其切换到TableController解决了这个问题。当脚手架确保使用'windows mobile services table controller'选项时

Answer 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查看。如果托管，则使用您的主密钥作为密码（用户名并不重要）。

TableControllers连接在/ tables / *路径下，而所有其他控制器连接在/ api / *下。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。
