Web API和OData-传递多个参数

Question

是否有可能让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REST方法,如 - > GetReports(22, 2014)或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));
}

这是我的最新变化.

  //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的方法

[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

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

Answer 1

您可以定义具有两个参数的名为GetReports的函数导入.

(注意:函数导入的名称不能与实体集名称相同)

将EDM模型配置为:

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();

然后将您的方法编写为:

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

然后是请求

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

将工作.
