我收到错误“没有找到与请求 URI 匹配的 HTTP 资源”

Question

Request URL:请求 URL：

/api/Test/Retrieve/14012638/?14012647

Endpoint:端点：

[Route("Retrieve/{firstid}/{secondid?}")]       
public async Task<TestAPI> Retrieve(long firstid, long secondid)

Answer 1

It is always better to place your route at the controller level and your HTTP verb at the action level.最好将您的路线放在 controller 级别，将 HTTP 动词放在操作级别。

For your requirement, you can do this like below.根据您的要求，您可以像下面那样执行此操作。 I assume you are doing a GET operation.我假设您正在执行GET操作。

[HttpGet("Retrieve/{firstid}/{secondid?}")]    
public async Task<WellsTradeAccountsInformation> Retrieve(long firstid, long secondid) { … }

If your controller' route is api/Test , then you can call this as:如果您的控制器的路由是api/Test ，那么您可以将其称为：

GET /api/Test/Retrieve/14012638/14012647

or或者

GET /api/Test/Retrieve/14012638

As the second parameter is an optional value type, if you don't pass it will default to 0.由于第二个参数是可选值类型，如果不传递默认为0。
