Question

Url.Link(...)上抛出以下异常：

An exception of type 'System.ArgumentException' occurred in System.Web.dll but was not handled in user code

Additional information: A route named 'api/companies/{companyId:Guid}' could not be found in the route collection.

这是控制器方法：

[Route("api/companies/")]
[HttpPost]
public IHttpActionResult Create()
{
    Company company = new Company("Test!");

    CompanyRepository.Add(company);

    return Created(new Uri(Url.Link("api/companies/{companyId:Guid}", new { companyId = company.Id })), company);
}

此处使用属性路由定义路径：

[Route("api/companies/{companyId:Guid}")]
[HttpGet]
public IHttpActionResult Get(Guid companyId)
{
    return Ok(CompanyRepository.Find(companyId));
}

为什么无法找到路线？我是否需要在RouteConfig中使用传统路由？

Answer 1

你需要这样命名你的路线：

[Route("api/companies/{companyId:Guid}", Name="MyRouteName")]

然后使用

Url.Link("MyRouteName", new { companyId = company.Id })

Url.Link（）：使用属性路由时找不到路由
