。NET Core大张旗鼓的查询字符串参数

Question

我有一个名为“ FootballControler”的控制器，具有以下端点：

• 获取/ api / FeedMatch
• 获取/ api / FeedMatch / ExternalMatchIdAndFeedLeagueId？externalMatchId = 0＆feedLeagueId = 0
• 获取/ api / FeedMatch / ExternalMatchIdAndFeedTypeId？externalMatchId = 0＆feedTypeId = 0
• 获取/ api / FeedMatch / feedMatchId = 2
• 获取/ api / FeedMatch / MatchId = 3
• 获取/ api / FeedMatch / dateMatch？dateMatch =“ 2012/1/1”

如您所见，所有端点都试图获取FeedMatch列表。我想要做的就是让他们像这样：

• 获取/ api / FeedMatch
• 获取/ api / FeedMatch？externalMatchId = 0＆feedLeagueId = 0
• 获取/ api / FeedMatch？externalMatchId = 0＆feedTypeId = 0
• 获取/ api / FeedMatch？feedMatchId = 2
• 获取/ api / FeedMatch？MatchId = 3
• 获取/ api / FeedMatch？dateMatch =“ 2012/1/1”

我的解决方案：

[HttpGet]
public List<Match> GetAll()
{
  return a list of matches. 
}

[HttpGet]
public List<Match> GetByMatchIdAndFeedLeagueId(string externalMatchId, int feedLeagueId)
{
  return a list of matches. 
}

[HttpGet]
public List<Match> GetByExternalMatchIdAndFeedTypeId(string externalMatchId, int feedTypeId)
{
  return a list of matches. 
}

[HttpGet]
public List<Match> GetByFeedMatchId(int feedMatchId)
{
  return a list of matches. 
}

[HttpGet]
public List<Match> GetByMatchId(int feedMatchId)
{
  return a list of matches. 
}

但是Swashbuckle在Asp.net核心中失败，并带有NotSupportedException异常。

我不想使用这样一种带有可选参数的方法：

[HttpGet]
public List<Match> Get(int? feedMatchId = null, int? feedMatchId = null,string externalMatchId = null ..... )
{
  return a list of matches. 
}

请帮助我解决此问题。谢谢

使用一个具有多个参数的功能。对于没有值的参数，您的函数将收到null。

[HttpGet]
public List<Match> GetSomething(
[FromQuery] int? externalMatchId,
[FromQuery] int? feedLeagueId,
[FromQuery] int? feedTypeId)
{
  if (externalMatchId.HasValue)
  {
      select by match id 
  }
  ...
  return a list of matches. 
}
