Azure MobileApp:InvokeApiAsync因InvalidOperationException失败

我正在试用Azure移动应用程序和最近发布的SDK

我创建了服务，starter Todo应用程序运行良好。然后我添加了facebook认证，这也起到了作用。我还想从该服务中获得一些额外的FB信息，因此基于github上的解决方案和示例应用程序，我添加了一个新的api

服务器端代码

public class AuthenticationController : ApiController
{
    [Authorize]
    public async Task<JObject> GetIdentity()
    {
        FacebookCredentials fb = await this.User.GetAppServiceIdentityAsync<FacebookCredentials>(this.Request);
        var result = new JObject();
        if (fb != null)
        {
            var accessToken = fb.AccessToken;
            result.Add("facebook", await GetProviderInfo("https://graph.facebook.com/me?access_token=" + accessToken));
        }

        return result;
    }

    private async Task<JToken> GetProviderInfo(string url)
    {
        var c = new HttpClient();
        var resp = await c.GetAsync(url);
        resp.EnsureSuccessStatusCode();
        return JToken.Parse(await resp.Content.ReadAsStringAsync());
    }

}

LoginAsync成功，我获得了用户ID和令牌，但InvokeApiAsync失败，出现以下异常

我错过了什么或做错了什么？

---

提前感谢。

我在使用新的Azure应用程序服务示例项目的项目中遇到了类似的错误。我只是尝试使用自己的模型类从Azure db检索数据，而不是像您那样进行身份验证

以下是错误：

Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException: 您正在查找的资源已被删除，其名称为 已更改，或暂时不可用

事实证明，在我的移动服务器项目中，我有一个定义为

CorporateEvent

的模型，在我的客户端项目中，我有一个定义为

CorporateEventModel

的相同模型。一旦我将客户项目中的模型重命名为

CorporateEvent

，错误就消失了，我能够访问数据库

希望有帮助。

请只发布相关代码，不要链接到外部代码源。另外，请正确设置错误消息的格式。我认为在调用“GetIdentity”时，身份验证头可能丢失。你能用小提琴来检查那个值吗？我认为您可以将Fiddler配置为Android仿真器的代理。您的控制器上是否有

[MobileAppController]

属性？要确认您是否缺少http请求头上的身份验证令牌，可以从`GetIdentity（）中删除

[Authorize]

`方法并重新部署您的服务，查看您是遇到相同的错误还是不同的错误。您在

GetProviderInfo（）

method中遇到问题了吗？你设定了什么权限？您可以使用“Graph API Explorer”生成具有所选权限的令牌。然后你可以用这个令牌测试你的代码。嘿，迈克尔，谢谢你的建议。。我在控制器上有

[MobileAppController]

属性。我甚至尝试删除所有身份验证。基本上创建了一个新服务，只添加了一个新的

ApiController

，其中包含一个

GetIdentity

方法，该方法只返回一个字符串并获得相同的

您正在查找的资源已被删除、名称已更改或暂时不可用。

错误。和小提琴手也没什么好运气。我通过fiddler代理了我的android设备。我看到所有应用程序的跟踪。但在移动应用程序中看不到任何内容。
