Question

知道最后两个URI模板报告端点未找到的原因吗？

v1/version
v1/locations/{id}
v1/locations/{id}/signals
v1/locations&q={searchText}
v1/locations/signals/{signalIds}
v1/signals/{id}
v1/locations/{id}/visits
v1/locations/{locationId}/visits/{id}

以前的所有6条路由都可以正常工作，但是当我添加最后2条路由时，它们会回复404“未找到端点”WCF框架消息。所有8条路线都是GET方法，我已经向Fiddler证实我确实使用了GET动词。我看不出与其他仍然有效的REST方法有什么不同。

成功获取位置ID = 2的测试网址

GET http://localhost:57004/AppsService.svc/v1/locations/2

返回正确的JSON：

{
    "Id": 2,
    "Identifier": "L85",
    "Name": "The Huge Lake",
    "Signals": null
}

以下是测试网址，尝试从位置ID = 2

获取所有“访问”对象

GET http://localhost:57004/AppsService.svc/v1/locations/2/visits

该URL因404框架异常而失败：

以下是完整的服务接口代码：

            UriTemplate = "v1/version")]
        string GetVersion();

        List<Location> GetLocationsContainingSignals(string signalIds);

        [OperationContract]
        [WebGet(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
            UriTemplate = "v1/locations/{id}/visits")]
        List<Visit> GetVisits(string id);

            UriTemplate = "v1/signals/{id}")]
        Signal GetSignal(string id);
    }
}

有什么想法吗？

发现问题：我。

在调试端点＃6之后，我将项目的OutputPath属性从默认的“bin”更改为“$（SolutionDir）\ $ Configuration”，这是我们用于所有项目的模式。

事实证明，当您从VS调试Web项目时，它总是在通过IIS或Cassini独立Web服务器启动项目时查找程序集的相对“bin \”文件夹。项目的OutputPath属性在没有投诉的情况下被忽略。

所以我不得不调试我的程序集的陈旧版本，它只包含前6个端点的路由。啧

找不到八个WCF REST端点中的两个的可能原因？
