Question

我正在尝试查询“ UserType”对象，并获取属性“ name” 因此，整个JSON对象为User：，并且api调用应如下所示： api/user?userTypeName=randomUserTypeName

我可以在其中搜索特定的userTypeName并返回名称。

API调用：

在这里，我要使用FromQuery，以便能够搜索userTypeName并检查userTypeName是否等于输入的名称。

// GET: /api/User/userTypeName
[HttpGet("{userTypeName}")]
public async Task<ActionResult<IEnumerable<User>>> GetAsync(([FromQuery(Name = "userTypeName")]string userTypeName) {
    var result = await ctx.User
        .Include(x => x.UserType)
        .Where(x => x.UserType.Name.ToLower() == UserTypeName.ToLower())
        .ToListAsync();

    if (result == null) return BadRequest();

    return result;
}

对象看起来像这样：

{
    "id": 9,
    "userTypeId": 1,
    "userType": {
    "id": 1,
    "name": "randomUserTypeName",
    "users": 
    [
        {
            "id": 11,
            "userTypeId": 1,
            "userUrl": "https://userurl",
            "username": "eee",
            "password": "eee",
        }
    ]
}

如果您想通过userTypeName之类的请求通过路由访问/api/User/userTypeName，则您的操作应为

[HttpGet("{userTypeName}")]
public async Task<ActionResult<IEnumerable<User>>> GetAsync(string userTypeName) {
    var result = await ctx.User
        .Include(x => x.UserType)
        .Where(x => x.UserType.Name.ToLower() == UserTypeName.ToLower())
        .ToListAsync();

    if (result == null) return BadRequest();

    return result;
}

如果您想通过userTypeName之类的请求从查询访问api/user?userTypeName=randomUserTypeName，则您的操作应为

[HttpGet]
public async Task<ActionResult<IEnumerable<User>>> GetAsync([FromQuery(Name = "userTypeName")]string userTypeName) {
    var result = await ctx.User
        .Include(x => x.UserType)
        .Where(x => x.UserType.Name.ToLower() == UserTypeName.ToLower())
        .ToListAsync();

    if (result == null) return BadRequest();

    return result;
}

GET json嵌套对象属性。 [FromQuery]
