Why razor pages don`t set a get param?
问题
当我尝试使用 /?page=1 参数获取我的 Razor 页面时，我期望我的 page 参数将是1，但它仍然是0。为什么它没有从URL中读取，我可以怎么做？
public async Task OnGetAsync(string[] tags, int page)
{
_logger.Log(LogLevel.Information, $"新的索引请求，页面 {page}");
var find = new Api.FindApi(cs);
posts = await find.Find(tags, Page * Constants.POST_PER_PAGE);
}
我还尝试了这个，但它仍然不起作用：
[FromQuery(Name = "page")]
public int Page { get; private set; }
英文:
When i try get my Razor page with /?page=1 params, i expect that my page param will be a 1, but it a still 0. Why is it not being read from the url and what can i do about it?
public async Task OnGetAsync(string[] tags, int page)
{
_logger.Log(LogLevel.Information, $"New index request, page {page}");
var find = new Api.FindApi(cs);
posts = await find.Find(tags, Page*Constants.POST_PER_PAGE);
}
I also tried this, but it still not working
[FromQuery(Name = "page")]
public int Page{get;private set;}

使用 [FromQuery(Name ="page")] 在你的参数前面来解决这个问题，就像这样：
public async Task OnGetAsync([FromQuery(Name ="page")]int page, string[] tags)
{
//Your Code
}
英文:
Use [FromQuery(Name ="page")] befor your parameter to solve this problem like this:
public async Task OnGetAsync([FromQuery(Name ="page")]int page, string[] tags)
{
//Your Code
}

除了FromQuery属性之外，在Razor页面中，你可能应该在这些查询参数属性上使用BindProperty属性。
你还应该移除Page的setter上的private修饰符。
[BindProperty(SupportsGet = true)]
public int Page { get; set; }
英文:
Instead of the FromQuery attribute, in a Razor page you should probably be using the BindProperty attribute on those query param properties.
You should also remove the private modifier on the setter for Page
[BindProperty(SupportsGet = true)]
public int Page { get; set; }
