Web API 和 OData- 传递多个参数 [英] Web API and OData- Pass Multiple Parameters

问题描述

是否可以让 OData 执行以下操作?我希望能够通过传递可能不是主键的参数来查询 REST 调用.我可以调用诸如 --> GetReports(22, 2014) 或 Reports(22, 2014) 之类的 REST 方法吗?

Is it possible to get OData to do the following? I would like to be able to query a REST call by passing on parameters than may not be the primary key. Can I call a REST method like --> GetReports(22, 2014) or Reports(22, 2014)?

[HttpGet]
[ODataRoute("Reports(Id={Id}, Year={Year})")]
public IHttpActionResult GetReports([FromODataUri]int Id, [FromODataUri]int Year)
{
    return Ok(_reportsRepository.GetReports(Id, Year));
}

这是我的最新更改.

  //Unbound Action  OData v3
       var action = builder.Action("ListReports");
        action.Parameter<int>("key");
        action.Parameter<int>("year");
        action.ReturnsCollectionFromEntitySet<Report>("Reports");

我的控制器 ReportsController 方法

[HttpPost]
            [EnableQuery]
             public IHttpActionResult ListReports([FromODataUri] int key, ODataActionParameters parameters)

            {

                if (!ModelState.IsValid)
                {
                    throw new HttpResponseException(HttpStatusCode.BadRequest);
                }


                int year = (int)parameters["year"];
                return Ok(_reportsRepository.GetReports(key, year).Single());

            }

我试着像这样调用网址:

 http://localhost:6064/odata/Reports(key=5,year=2014)/ListReports

未找到与请求 URI 'http://localhost:6064/odata/Reports(key%3D5%2Cyear%3D2014)/ListReports'匹配的 HTTP 资源.`

No HTTP resource was found that matches the request URI 'http://localhost:6064/odata/Reports(key%3D5%2Cyear%3D2014)/ListReports'.`

推荐答案

您可以定义一个名为 GetReports 的函数导入，它有两个参数.

You can define a function import named GetReports that has two parameters.

(注意:函数导入的名称不能与实体集名称相同)

将您的 EDM 模型配置为:

Configure your EDM model as:

var builder = new ODataConventionModelBuilder();
builder.EntitySet<Report>("Reports");
var function = builder.Function("GetReports");
function.Parameter<int>("Id");
function.Parameter<int>("Year");
function.ReturnsCollectionFromEntitySet<Report>("Reports");
var model = builder.GetEdmModel();

然后将您的方法写为:

[HttpGet]
[ODataRoute("GetReports(Id={Id},Year={Year})")]
public IHttpActionResult WhateverName([FromODataUri]int Id, [FromODataUri]int Year)
{
    return Ok(_reportsRepository.GetReports(Id, Year));
}

然后请求

Get ~/GetReports(Id=22,Year=2014)

会起作用.
