角度应用程序中的请求返回状态400

分类：编程问答

如何解决角度应用程序中的请求返回状态400

我正在尝试向asp.net核心后端发送发布请求，以验证输入名称，但收到状态为400错误的请求。

这是控制器：

menu()

这是角度应用程序中的相应服务调用：

[Route("api/masterdata/general/companies")]
[ApiController]
public class CompanyController : Controller
{
    private DataContext DataContext;

    public CompanyController(DataContext dataContext)
    {
        DataContext = dataContext;
    }

    [HttpGet("{id}")]
    public Company GetCompany(long Id)
    {
        return DataContext.Companies.Find(Id);
    }

    [HttpGet]
    public IEnumerable<Company> GetCompanies()
    {
        return DataContext.Companies;
    }

    [HttpPost("validatename/{name}")]
    public JsonResult ValidateName(string name)
    {
        IEnumerable<Company> companies = DataContext.Companies;

        bool isValid = !companies.Any(c => Common.CleanName(c.Name) == Common.CleanName(name));

        return Json(isValid);
    }
}

为什么收到我的错误要求？ validateName(name: string): Observable<any> { return this.http.post<boolean>("api/masterdata/general/companies/validatename/" + name,null); } api调用是f达到并且工作正常。

谢谢。

解决方法

尝试一下：

house_data["bedrooms"] = ''
house_data["bedrooms"] = house_data["Amenities"].str.extract("(\d*\.?\d+)",expand=True)

2098    3
2099    2
2100    3
Name: bedrooms,Length: 1213,dtype: object

或更好

var cleanName=  Common.CleanName(name);
var isValid = !DataContext.Companies.Any(c => Common.CleanName(c.Name) == cleanName);
return Json(new { isValid = isValid.ToString() });
,

问题是，我在ConfigureServices方法中注册了防伪令牌功能：

services.AddAntiforgery(options => { options.HeaderName = "X-XSRF-TOKEN"; });

但是我忘记将反伪造令牌添加到像这样的来自角度的请求中：

    app.Use(nextDelegate => context =>
    {
        string path = context.Request.Path.Value;
        string[] directUrls = { "/masterdata" };
        if (path.StartsWith("/api") || string.Equals("/",path) || directUrls.Any(url => path.StartsWith(url)))
        {
            var tokens = antiforgery.GetAndStoreTokens(context);
            context.Response.Cookies.Append("XSRF-TOKEN",tokens.RequestToken,new CookieOptions()
            {
                HttpOnly = false,Secure = false,IsEssential = true
            });
        }
        return nextDelegate(context);
    });

现在，它可以工作了（状态200）。
