在In Asp.net Core 2.2.1中访问XMLHttpRequest

Moh*_*iri 0 asp.net-core angular

在我的Asp.net核心项目中,我使用Microsoft.AspNetCore.App Version =“ 2.2.1”并在启动服务中调用AddCors
Startup.cs

public void ConfigureServices(IServiceCollection services)
{
 services.AddCors(options =>
    {
        options.AddPolicy("CorsPolicy",
            builder => builder
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()
                );
    });

    .....

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseCors(policyName: "CorsPolicy");  

            ....

在angular 5 App中,当调用Web API时,在浏览器的控制台中显示此错误

CORS策略已阻止从原点' http:// localhost:4200 ' 访问' http:// localhost:5000 / api / Account / LoginByPortal ' 上的XMLHttpRequest :对预检请求的响应未通过访问控制检查:当请求的凭据模式为“ include”时,响应中“ Access-Control-Allow-Origin”标头的值不得为通配符“ *”。XMLHttpRequest发起的请求的凭据模式由withCredentials属性控制。

角度服务:

loginByPortal(credentials: Credentials): Observable<userLoginViewmodel> {
    const headers = new HttpHeaders({ 'Content-Type': 'application/json' });
    return this.http
      .post(`${this.appConfig.apiEndpoint}/Account/LoginByPortal`, credentials,
       { headers: headers, withCredentials: true /* For CORS */ })     
      .map(response => response || {})
      .catch((error: HttpErrorResponse) => Observable.throw(error));
  }

我不想使用.WithOrigins("http://localhost:4200"
我想在CoresPloicy中使用AllowAnyOrigin有
什么问题?我该如何解决?

这是解决方案:https : //stackoverflow.com/a/53790841/8801075

app.UseCors(builder => builder
                .AllowAnyHeader()
                .AllowAnyMethod()
                .SetIsOriginAllowed((host) => true)
                .AllowCredentials()
            );
