如何在Dot Net Core Web API中处理OPTION标头 [英] How to handle OPTION header in dot net core web api

问题描述

在使用ajax调用测试我的点网核心网络api时，当我用提琴手监视时，chrome用请求头中的Option替换了我的get。我在此处在上为CORS启用了OPTIONS标头。 NET Core Web API 仍然无法正常工作。我该如何实现？这是我的启动文件

While testing my dot net core web api with ajax call, chrome replaces my get with Option in the request header when i monitor with fiddler. I followed the code here Enable OPTIONS header for CORS on .NET Core Web API and still not working. How do I achieve this? Here is my start up file

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<CookiePolicyOptions>(options =>
    {
        options.CheckConsentNeeded = context => true;
        options.MinimumSameSitePolicy = Microsoft.AspNetCore.Http.SameSiteMode.None;
    });

    services.AddCors(options => options.AddPolicy("AllowCors", p => 
        p.AllowAnyOrigin().AllowAnyMethod().AllowCredentials().AllowAnyHeader()));

    services.Configure<IISOptions>(options =>
    {
        options.ForwardClientCertificate = false;
    });

    services.AddMvc()
        .SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }

    app.UseOptions();
    app.UseCors("AllowCors");
    app.UseDefaultFiles();
    app.UseStaticFiles();
    app.UseCookiePolicy();
    app.UseHttpsRedirection();

    app.UseMvc(routes =>
    {
        routes.MapRoute(name: "default", template: "{controller=Account}/{action=Login}/{id?}");
    });
}

推荐答案

这应启用OPTION标头

This should enable OPTION header

          app.UseCors(builder => builder.WithOrigins("http://example.com")
          .AllowAnyHeader()
          .AllowAnyMethod()
          .AllowCredentials());

使其适合您的需求。
