将swashbuckle中的参数设为可选(不需要) [英] Make parameters in swashbuckle optional(not required)

问题描述

我想在控制器中将param设置为可选参数，但会大摇大摆地根据需要显示它.

I want to make param in my controller as optional but swagger shows it as required.

我的控制器看起来像:

[HttpGet("{name}")]
[SwaggerResponse((int)HttpStatusCode.OK)]
[SwaggerResponse((int)HttpStatusCode.BadRequest)]
public async Task<IActionResult> GetPolicy(string name)
 {
     if (string.IsNullOrEmpty(name))
     {
         return BadRequest("Name is empty");
     }
     try
     {
         CRUDPolicyResponse crudPolicyResponse = await _managementOperations.CRUDPolicy(CRUDType.Read, name, null);
         if (!crudPolicyResponse.OperationSucceeded)
         {     
            return StatusCode((int)HttpStatusCode.BadRequest, crudPolicyResponse.Message);
         }
         if (crudPolicyResponse.FileMetadataPolicy == null)
         {
             return NotFound($"Policy name doesn't exists NAME: {name}");
         }
         return Ok(crudPolicyResponse.FileMetadataPolicy);
     }
     catch (Exception ex)
     {
        _log.Error("Error while trying to save file meta data policy", ex);
            return StatusCode((int)HttpStatusCode.InternalServerError, ex);
     }
 }

我试图更改为默认值，例如:string name = null，但无法正常工作/

I tried to change to default value like this: string name = null but not working/

因此，名称字符串是必需的，我无法使名称为空.

So the name string is required and i can't make get with name as empty.

我试图用此解决方案解决我的问题 将int设为可为空

I tried to solve my problem with this solution make int as nullable

推荐答案

将默认值添加到控制器参数

Add the default value to your controller parameter

[HttpGet("{name}")]
[SwaggerResponse((int)HttpStatusCode.OK)]
[SwaggerResponse((int)HttpStatusCode.BadRequest)]
public async Task<IActionResult> GetPolicy(string name = "")
 {
...
}
